With that word, David Limp, on the time Amazon’s head of gadgets and products and services, confirmed off a brand new generative AI-powered model of the corporate’s signature Alexa voice assistant in September 2023.
At a packed match on the Seattle-based tech massive’s lavish 2d headquarters within the Washington DC suburbs, Limp demonstrated the brand new Alexa for a room stuffed with newshounds and cheering staff. He confirmed how based on the brand new cause word, “Alexa, let’s chat,” the virtual assistant answered in a much more pure and conversational voice than the friendly-but-robotic one who masses of hundreds of thousands have turn into familiar with speaking with for climate updates, reminders, timers and tune requests. Limp requested Alexa how his favourite soccer crew—Vanderbilt College—used to be doing. Alexa confirmed how it will reply in a completely happy voice, and the way it will write a message to his pals to remind them to observe the impending Vanderbilt soccer sport and ship it to his telephone.
The brand new Alexa LLM, the corporate mentioned, would quickly be to be had as a loose preview on Alexa-powered gadgets in the United States. Rohit Prasad, Amazon’s SVP and Alexa chief mentioned the scoop marked a “huge transformation of the assistant we like,” and referred to as the brand new Alexa a “tremendous agent.” It used to be transparent the corporate sought after to refute perceptions that the present Alexa lacked smarts. (Microsoft CEO Satya Nadella reportedly referred to as it “dumb as a rock” in March 2023 as OpenAI’s ChatGPT rocketed to status).
However after the development, there used to be radio silence—or virtual assistant silence, because the case is also. The normal Alexa voice by no means modified at the half-a-billion gadgets which have been bought globally, and little information emerged over the approaching months concerning the new generative AI Alexa, rather than fresh experiences a couple of doable release later this 12 months that might come with a subscription rate.
The rationale, in line with interviews with greater than a dozen former staff who labored on AI for Alexa, is a corporation beset by way of structural disorder and technological demanding situations that experience many times not on time cargo of the brand new generative AI-powered Alexa. General, the previous staff paint an image of an organization desperately at the back of its Large Tech opponents Google, Microsoft, and Meta within the race to release AI chatbots and brokers, and floundering in its efforts to catch up.
The September 2023 demo, the previous staff emphasize, used to be simply that—a demo. The brand new Alexa used to be now not able for a chief time rollout, and nonetheless isn’t. The Alexa massive language mannequin (LLM), that sits on the middle of the brand new Alexa, and which Amazon situated as taking over OpenAI’s ChatGPT, is, in line with former staff, a ways from cutting-edge. Analysis scientists who labored at the LLM mentioned Amazon does now not have sufficient knowledge or get admission to to the specialised pc chips had to run LLMs to compete with rival efforts at corporations like OpenAI. Amazon has additionally, former staff say, many times deprioritized the brand new Alexa in prefer of establishing generative AI for Amazon’s cloud computing unit, AWS. And whilst Amazon has constructed a partnership and invested $4 billion in AI startup Anthropic, whose LLM mannequin Claude is regarded as aggressive with OpenAI’s fashions, it’s been not able to capitalize on that courting to construct a greater Alexa. Privateness issues have stored Alexa’s groups from the usage of Anthropic’s Claude mannequin, former staff say—yet so too have Amazon’s ego-driven inside politics.
An Amazon spokesperson mentioned main points supplied by way of the previous analysis scientists for this tale have been “dated” —despite the fact that many of those resources left the corporate up to now six months—and didn’t replicate the present state of the Alexa LLM. She added that the corporate has get admission to to masses of 1000’s of GPUs and different AI-specific chips. She additionally disputed the concept Alexa has been deprioritized or that Anthropic’s Claude has been off-limits because of privateness issues, yet she declined to offer proof of the way Claude is getting used within the new Alexa.
Whilst sides of Amazon’s battle to replace Alexa are distinctive, the corporate’s demanding situations give a sign of the way tricky it’s for firms to redesign virtual assistants constructed on older applied sciences to include generative AI. Apple, too, has confronted identical struggles to combine AI into its merchandise, together with its virtual assistant Siri. Siri and Alexa percentage a identical technological pedigree—in truth, Siri debuted 3 years previous to Alexa, in October 2011. And prefer Amazon, Apple underinvested in the type of AI experience had to construct the large language fashions that underpin these days’s generative AI, and within the huge clusters of graphics processing devices (GPUs), the specialised pc chips such fashions require. Apple too, like Amazon, has introduced a decided, yet belated, effort to catch up.

Apple took some large steps against regaining misplaced flooring within the generative AI race with a suite of highly-anticipated bulletins at its WWDC convention previous this week. The debut integrated a large improve for Siri, together with a extra natural-sounding voice and the potential of “on-screen consciousness,” which is able to sooner or later permit Siri to take extra agent-like movements throughout apps. Apple additionally introduced a Siri integration with ChatGPT. Apple’s bulletins most effective up the power on Amazon to ship the brand new Alexa.
Sadly, there’s rising proof that Amazon is ill-prepared for this renewed combat of the virtual assistants—despite the fact that many assumed the corporate would had been completely situated to take Alexa into the generative AI age. The previous day, Mihail Eric, a former senior gadget studying scientist at Alexa AI, took to X (previously Twitter) to mention simply that: In a submit titled “How Alexa dropped the ball on being the highest conversational machine on this planet,” Eric, who left Amazon in July 2021, identified that Alexa had bought over 500 million gadgets, “which is a mind-boggling consumer knowledge moat,” and that “we had all of the assets, ability, and momentum to turn into the unequivocal marketplace chief in conversational AI.” However maximum of that tech by no means noticed the sunshine of day, he mentioned, as a result of Alexa AI “used to be riddled with technical and bureaucratic issues.” The dozen former staff Fortune spoke to over the last month echo Eric’s account and upload additional main points to the tale of the way the The entirety Corporate has failed to try this something. The previous staff spoke anonymously to steer clear of violating non-disclosure agreements or non-disparagement clauses that they had signed.
Amazon Alexa used to be stuck flat-footed by way of ChatGPT
Neatly prior to ChatGPT wowed the arena in November 2022, there used to be Amazon’s Alexa. The virtual assistant used to be introduced in 2014 along the Echo sensible speaker that served as its {hardware} interface. The virtual assistant, Amazon mentioned, were impressed by way of the all-knowing pc featured on Megastar Trek (Amazon founder Jeff Bezos is a large Megastar Trek fan). The product briefly was a success with shoppers, promoting over 20 million gadgets by way of 2017. However Alexa used to be now not constructed at the similar AI fashions and strategies that made ChatGPT groundbreaking. As a substitute, it used to be a choice of small gadget studying fashions and 1000’s of handmade and hard-coded laws that grew to become a consumer’s utterances into the movements Alexa carried out.
Amazon were experimenting with some early massive language fashions—they all a lot smaller than GPT-3 and GPT-4, the 2 fashions OpenAI would use to energy ChatGPT—yet those have been nowhere close to able for deployment in a product. The corporate used to be stuck flat-footed by way of the generative AI increase that adopted ChatGPT’s past due November 2022 release, former staff say. A frantic, frenetic few months adopted as Amazon’s Alexa group struggled to coalesce round a imaginative and prescient to take the virtual assistant from a stilted command-action bot to a really conversational, useful agent. Non-generative AI tasks have been deprioritized in a single day, and right through the 2022 Christmas length executives instructed Amazon’s scientists, engineers and product managers to determine how to make sure Amazon had generative AI merchandise to supply consumers. One former Alexa AI mission supervisor described the ambience on the corporate as “a little bit panicked.”Amazon’s reaction virtually in an instant bumped into bother, as quite a lot of groups inside of Alexa and AWS didn’t coalesce round a unified plan. Many staff have been nonetheless operating remotely following the Covid pandemic, resulting in other people being forever “huddled on convention calls debating the trivialities of strategic PRFAQs” (Amazon-speak for a written file used when proposing a product concept in its early levels), the Alexa AI mission supervisor mentioned. The corporate struggled, he mentioned, to “shift from peacetime to wartime mode.”
One senior Alexa knowledge scientist mentioned this used to be particularly irritating as a result of he had attempted to sound the alarm at the coming wave of generative AI way back to mid-2022, amassing knowledge to turn his director-level management, yet he mentioned he may now not persuade them that the corporate had to alternate its AI technique. Handiest after ChatGPT introduced did the corporate swing into motion, he defined.

The issue is, as masses of hundreds of thousands are conscious from their stilted discourse with Alexa, the assistant used to be now not constructed for, and hasn’t ever been essentially used for, back-and-forth conversations. As a substitute, it all the time considering what the Alexa group calls “utterances” — the questions and instructions like “what’s the elements?” or “flip at the lighting fixtures” that folks bark at Alexa.
Within the first months after ChatGPT introduced, it used to be now not transparent LLMs would be capable to cause those real-world movements from a pure dialog, one Ph.D. analysis scientist who interned at the Alexa crew all over this era mentioned. “The concept that an LLM may ‘transfer at the lighting fixtures’ while you mentioned ‘I will’t see, flip all of it on’ used to be now not confirmed but,” he mentioned. “So the leaders internally obviously had large plans, yet they didn’t in point of fact know what they have been entering.” (It’s now broadly authorized that LLMs can, no less than in principle, be coupled with different era to keep watch over virtual gear.)
As a substitute, groups have been understanding find out how to enforce generative AI at the fly. That integrated developing artificial datasets —on this case, collections of computer-generated dialogues with a chatbot—that they might use to coach an LLM. The ones development AI fashions regularly use artificial knowledge when there isn’t sufficient real-world knowledge to beef up AI accuracy, or when privateness coverage is wanted— and have in mind, maximum of what the Alexa crew had have been easy, declarative “utterances.”
“[Customers were] speaking in Alexa language,” one former Amazon gadget studying scientist mentioned. “So now consider you wish to have to inspire other people to speak in language that hasn’t ever took place—so the place are you going to get the knowledge from to coach the mannequin? It’s a must to create it, yet that incorporates a number of hurdles as a result of there’s a gazillion tactics other people can say the similar factor.”
Additionally, whilst Alexa has been built-in with 1000’s of third-party gadgets and products and services, it seems that LLMs don’t seem to be extraordinarily just right at dealing with such integrations. In step with a former Alexa gadget studying supervisor, who labored on Alexa’s sensible house features, even OpenAI’s newest GPT 4o mannequin, or the latest Google Gemini mannequin—which each are ready to make use of voice, quite than simply textual content—battle to move from spoken discussion to acting a role the usage of different instrument. That calls for what’s referred to as an API name and LLMs don’t do that smartly but.
“It’s now not constant sufficient, it hallucinates, will get issues incorrect, it’s tough to construct an enjoy while you’re connecting to many alternative gadgets,” the previous gadget studying scientist mentioned.
As spring gave technique to the summer time of 2023, many in Alexa’s rank and document remained at midnight about how the virtual assistant would meet the generative AI second. The mission lacked imaginative and prescient, former staff mentioned. “I have in mind my crew and myself complaining so much to our superiors that it wasn’t clear what the imaginative and prescient looks as if—it wasn’t clear what precisely we’re seeking to release,” one mentioned. Some other former supervisor mentioned the brand new Alexa LLM used to be mentioned within the months previous to the September demo, however it wasn’t transparent what it could imply. “We have been simply listening to such things as, ‘Oh yeah, that is coming,’” he mentioned. “However we had no concept what it used to be or what it could appear to be.”

Alexa LLM demo didn’t meet ‘pass/no-go’ standards
The September 2023 Alexa demo made it appear to be a standard rollout of the brand new Alexa LLM used to be approaching. However the brand new language model-based Alexa in the end “didn’t meet the pass/no-go standards,” one former worker mentioned. LLMs are recognized for generating hallucinations and on occasion poisonous content material, and Amazon’s used to be no other, making huge liberate dangerous.
This, former staff say, is the explanation Alexa’s “Let’s Chat” characteristic hasn’t ever made it into broad liberate. “It’s very tough to make AI protected sufficient and take a look at all sides of that black field in an effort to liberate it,” a former supervisor mentioned.
The September 2023 demo, he identified, concerned other capability than what Alexa used to be very best recognized for— this is, taking a command and executing it. Making sure Alexa may nonetheless carry out those previous purposes whilst additionally enabling the conversational discussion the brand new Alexa promised could be no simple activity. The chief mentioned it used to be an increasing number of transparent to him that the group would, no less than quickly, wish to care for two utterly other era stacks—one supporting Alexa’s previous options and any other the brand new ones. However managers didn’t need to entertain that concept, he mentioned. As a substitute, the message on the corporate on the time he used to be laid off in November 2023 used to be nonetheless “we wish to principally burn the bridge with the previous Alexa AI mannequin and pivot to simply operating at the new one.”
Whilst the brand new Alexa LLM rollout floundered, Amazon executives set ever extra lofty generative AI targets. Proper prior to the demo, Prasad, the Amazon SVP who had served as Alexa’s head scientist, used to be promoted to a brand new position designed to carry the corporate’s disparate analysis groups below a unmarried umbrella, with a function to expand human-level synthetic common intelligence, or AGI. The transfer put Amazon in direct pageant with corporations like OpenAI, Google DeepMind, and Anthropic, that have the advent of AGI as their founding undertaking. Meta CEO Mark Zuckerberg has additionally just lately mentioned that developing AGI is his corporate’s undertaking too.
Via November 2023, there used to be phrase that Amazon used to be making an investment hundreds of thousands in coaching an AI mannequin, codenamed Olympus, that may have 2 trillion parameters—or tunable variables. Parameters are a coarse approximation of a mannequin’s measurement and complexity. And Olympus’s reported parameter depend would make it double the reported measurement of OpenAI’s maximum succesful mannequin, GPT-4.
The previous analysis scientist operating at the Alexa LLM mentioned Challenge Olympus is “a comic story,” including that the most important mannequin in development is 470 billion parameters. He additionally emphasised that the present Alexa LLM model is unchanged from the 100 billion-parameter mannequin that used to be used for the September 2023 demo, yet has had extra pretraining and superb tuning performed on it to beef up it. (To make sure, 100 billion parameters continues to be a reasonably tough mannequin. Meta’s Llama 3, as a comparability, weighs in at 70 billion parameters).
A loss of knowledge made it tricky to ‘get some magic’ out of the LLM
Within the months following the September 2023 demo, a former analysis scientist who labored on development the brand new Alexa LLM recalled how Alexa management, together with Amazon’s generative AI chief Rohit Prasad, driven the crew to paintings tougher and tougher. The message used to be to “get some magic” out of the LLM, the analysis scientist mentioned. However the magic by no means took place. A loss of ok knowledge used to be one of the vital major explanation why, former staff mentioned.
Meta’s Llama 3 used to be pre-trained on 15 trillion tokens, the smallest unit of knowledge that an LLM processes. The Alexa LLM has most effective been skilled on 3 trillion. (Not like parameters, which might be the choice of tunable settings {that a} mannequin has, a token is the small unit of knowledge – similar to a phrase – that the mannequin processes all over coaching). In the meantime, “fine-tuning” an AI mannequin—which takes a pre-trained mannequin and extra hones it for particular duties—additionally advantages from higher datasets than what Amazon has on the able. Meta’s Llama 3 mannequin used to be fine-tuned on 10 million knowledge issues. The LLM constructed by way of Amazon’s AGI group has thus far accrued most effective round 1 million, with most effective 500,000 top of the range knowledge issues, the previous Alexa LLM analysis scientist mentioned.

Some of the many causes for that, he defined, is that Amazon insists on the usage of its personal knowledge annotators (other people accountable for labeling knowledge in order that AI fashions can acknowledge patterns) and that group may be very sluggish. “So we will be able to by no means by no means get top quality knowledge from them after a number of rounds, even after three hundred and sixty five days of creating the mannequin,” he mentioned.
Past a paucity of knowledge, the Alexa crew additionally lacks get admission to to the huge amounts of the most recent Nvidia GPUs, the specialised chips used to coach and run AI fashions, that the groups at OpenAI, Meta, and Google have, two resources instructed Fortune. “Lots of the GPUs are nonetheless A100, now not H100,” the previous Alexa LLM analysis scientist added, regarding probably the most tough GPU Nvidia recently has to be had.
Now and then, development the brand new Alexa has taken a backseat to different generative AI priorities at Amazon, they mentioned. Amazon’s major center of attention after ChatGPT introduced used to be to roll out Bedrock, a brand new AWS cloud computing provider that allowed consumers to construct generative AI chatbots and different programs within the cloud—which used to be introduced in April 2023 and made normally to be had in September. AWS is a vital profit-driver for Amazon.
Alexa, then again, is a price middle—the department reportedly loses billions each and every 12 months—and is most commonly seen so as to stay consumers engaged with Amazon and so as to accumulate knowledge that may lend a hand Amazon and its companions higher goal promoting. The LLM that Amazon scientists are development (a model of which may even energy Alexa) could also be first being rolled out to AWS’ business-focused generative AI assistant Amazon Q, mentioned a former Alexa LLM scientist who left inside the previous few months, since the mannequin is now regarded as just right sufficient for particular undertaking use circumstances. Amazon Q additionally faucets Anthropic’s Claude AI mannequin. However Alexa’s LLM crew has now not been allowed to make use of Claude because of issues about knowledge privateness.
Amazon’s spokesperson mentioned the statement about Claude and privateness is fake, and disputed different information about Amazon’s LLM effort that Fortune heard from more than one resources. “It’s merely erroneous to state Amazon Q is a better precedence than Alexa. It’s additionally improper to state that we’re the usage of the similar LLM for Q and Alexa.”
Paperwork and infrastructure problems bogged down Alexa’s gen AI efforts
One former Alexa AI worker who has employed a number of staff who were operating at the new Alexa LLM mentioned that almost all have discussed “feeling exhausted” by way of the consistent power to able the mannequin for a release this is many times postponed—and annoyed as a result of different paintings is on cling till within the intervening time. A couple of have additionally conveyed a rising skepticism as as to if the entire design of the LLM-based Alexa even is smart, he added.
“One tale I heard used to be that early within the mission, there used to be a large push from senior executives who had turn into overconfident after experimenting with ChatGPT, and that this overconfidence has continued amongst some senior leaders who proceed to power towards an unrealistic-feeling function,” he mentioned. Some other former Alexa LLM scientist mentioned managers set unachievable time limits. “Each and every time the managers assigned us a role associated with [the] LLM, they asked us to finish it inside of an excessively quick time period (e.g., 2 days, one week), which is unimaginable,” he mentioned. “It kind of feels the management doesn’t know the rest about LLMs—they don’t know what number of people they want and what must be the predicted time to finish each and every activity for development a a hit product like ChatGPT.”

Alexa by no means aligned with Jeff Bezos’ concept of “two-pizza groups”—this is, that groups must preferably be sufficiently small that you might want to cater a complete crew assembly with simply two pizzas. Bezos concept smaller groups drove efficient decision-making and collaboration. As a substitute, Alexa has traditionally been—and stays, for probably the most section—a large department. Previous to the latest layoffs, it had 10,000 staff. And whilst it has fewer now, it’s nonetheless arranged into massive, siloed domain names similar to Alexa House, Alexa Leisure, Alexa Track and Alexa Buying groceries, each and every with masses of staff, in conjunction with administrators and a VP on the most sensible.
As power grew for each and every area to paintings with the brand new Alexa LLM to craft generative AI options, each and every of which required accuracy benchmarks, the domain names got here into battle, with on occasion counterproductive effects, resources mentioned.
As an example, a gadget studying scientist operating on Alexa House recalled that whilst his area used to be operating on tactics for Alexa to lend a hand customers keep watch over their lighting fixtures or the thermostat, the Track area used to be busy operating on find out how to get Alexa to know very particular requests like “play Rihanna, then Tupac, after which pause half-hour after which play DMX.”
Each and every area crew needed to construct its personal courting with the central Alexa LLM crew. “We spent months operating with the ones LLM guys simply to know their construction and what knowledge lets give them to fine-tune the mannequin to make it paintings.” Each and every crew sought after to fine-tune the AI mannequin for its personal area targets.
However because it grew to become out, if the House crew attempted to fine-tuned the Alexa LLM to make it extra succesful for House questions, after which the Track crew got here alongside and fine-tuned it the usage of their very own knowledge for Track, the mannequin would finally end up acting worse. “Catastrophic forgetting,” the place what a mannequin learns later in coaching degrades its skill to accomplish smartly on duties it encountered previous in coaching is an issue with all deep studying fashions. “Because it will get higher in Track, [the model] can get much less sensible at House,” the gadget studying scientist mentioned. “So discovering the candy spot the place you’re seeking to superb track for 12 domain names is nearly a lottery.” This present day, he added, LLM scientists know that superb tuning might not be the most efficient method for making a mannequin with each wealthy features and versatility—there are others, like urged engineering, that may do higher. However by way of then, many months had long past by way of with little development to turn for it.
Each and every Alexa area, with its personal management, sought after to offer protection to and amplify its fiefdom, one former product supervisor mentioned. “This group has simply grew to become out into one thing like a mafia,” she mentioned. “Let’s say, if I be just right for you, I’m simply taking orders as a result of it’s in my very best passion to accept as true with you. It’s my very best passion not to get chopped off within the subsequent layoff—it’s fairly ruthless. It’s in my very best passion since you’re going to lend a hand me construct my empire.”
Amazon says it stands by way of its dedication to Alexa
Amazon insists it’s absolutely dedicated to handing over a generative AI Alexa, including that its imaginative and prescient stays to construct the “global’s very best non-public assistant.” An Amazon consultant identified that over half of one thousand million Alexa-enabled gadgets had been bought, and consumers engage with Alexa tens of hundreds of thousands of instances each and every hour.

She added that the implementation of generative AI comes with “large accountability—the main points in point of fact topic” with a technical implementation of this scale, on a tool that hundreds of thousands of consumers have welcomed into their house. Whilst the Alexa LLM “Let’s chat” characteristic has now not been rolled out to most people, it’s been examined on small teams of consumers “on an ongoing foundation.”
However most of the staff Fortune spoke to mentioned they left partly as a result of they despaired that the brand new Alexa would ever be able—or that by the point it’s, it’s going to had been overtaken by way of merchandise introduced by way of nimbler competition, similar to OpenAI. The ones corporations don’t must navigate an current tech stack and shield an current characteristic set. The previous worker who has employed a number of who left the Alexa group over the last 12 months mentioned many have been pessimistic concerning the Alexa LLM release. “They only didn’t see that it used to be in fact going to occur,” he mentioned.
It’s conceivable, say probably the most staff Fortune interviewed, that Amazon will in the end release an LLM-based Alexa — and that it’s going to be an development to these days’s Alexa. In spite of everything, there are masses of hundreds of thousands of Alexa customers available in the market on the planet who would indubitably feel free if the instrument sitting on their table or kitchen counter may do greater than execute easy instructions.
However given the demanding situations weighing down the Alexa LLM effort, and the space setting apart it from the choices of generative AI leaders like OpenAI and Google, not one of the resources Fortune spoke with consider Alexa is just about carrying out Amazon’s undertaking of being “the arena’s very best non-public assistant,” let on my own Amazon founder Jeff Bezos’ imaginative and prescient of making a real-life model of the useful Megastar Trek pc. As a substitute, Amazon’s Alexa runs the danger of changing into a virtual relic with a cautionary story— that of a doubtlessly game-changing era that were given caught taking part in the incorrect sport.
