AI labs are racing to construct knowledge facilities as large as Manhattan, every costing billions of {dollars} and consuming as a lot vitality as a small metropolis. The trouble is pushed by a deep perception in “scaling” — the concept including extra computing energy to present AI coaching strategies will finally yield superintelligent programs able to performing every kind of duties.
However a rising refrain of AI researchers say the scaling of enormous language fashions could also be reaching its limits, and that different breakthroughs could also be wanted to enhance AI efficiency.
That’s the wager Sara Hooker, Cohere’s former VP of AI Analysis and a Google Mind alumna, is taking along with her new startup, Adaption Labs. She co-founded the corporate with fellow Cohere and Google veteran Sudip Roy, and it’s constructed on the concept scaling LLMs has develop into an inefficient option to squeeze extra efficiency out of AI fashions. Hooker, who left Cohere in August, quietly announced the startup this month to start out recruiting extra broadly.
In an interview with TechCrunch, Hooker says Adaption Labs is constructing AI programs that may constantly adapt and study from their real-world experiences, and accomplish that extraordinarily effectively. She declined to share particulars in regards to the strategies behind this method or whether or not the corporate depends on LLMs or one other structure.
“There’s a turning level now the place it’s very clear that the method of simply scaling these fashions — scaling-pilled approaches, that are engaging however extraordinarily boring — hasn’t produced intelligence that is ready to navigate or work together with the world,” stated Hooker.
Adapting is the “coronary heart of studying,” in keeping with Hooker. For instance, stub your toe if you stroll previous your eating room desk, and also you’ll study to step extra fastidiously round it subsequent time. AI labs have tried to seize this concept by means of reinforcement studying (RL), which permits AI fashions to study from their errors in managed settings. Nonetheless, right this moment’s RL strategies don’t assist AI fashions in manufacturing — that means programs already being utilized by clients — to study from their errors in actual time. They only preserve stubbing their toe.
Some AI labs provide consulting companies to assist enterprises fine-tune their AI fashions to their customized wants, however it comes at a value. OpenAI reportedly requires clients to spend upwards of $10 million with the corporate to supply its consulting companies on fine-tuning.

“We’ve got a handful of frontier labs that decide this set of AI fashions which can be served the identical option to everybody, they usually’re very costly to adapt,” stated Hooker. “And truly, I feel that doesn’t must be true anymore, and AI programs can very effectively study from an atmosphere. Proving that may fully change the dynamics of who will get to regulate and form AI, and actually, who these fashions serve on the finish of the day.”
Adaption Labs is the most recent signal that the trade’s religion in scaling LLMs is wavering. A latest paper from MIT researchers discovered that the world’s largest AI fashions may soon show diminishing returns. The vibes in San Francisco appear to be shifting, too. The AI world’s favourite podcaster, Dwarkesh Patel, lately hosted some unusually skeptical conversations with well-known AI researchers.
Richard Sutton, a Turing award winner thought to be “the daddy of RL,” advised Patel in September that LLMs can’t truly scale as a result of they don’t study from actual world expertise. This month, early OpenAI worker Andrej Karpathy advised Patel he had reservations in regards to the longterm potential of RL to enhance AI fashions.
These kinds of fears aren’t unprecedented. In late 2024, some AI researchers raised considerations that scaling AI fashions by means of pretraining — wherein AI fashions study patterns from heaps of datasets — was hitting diminishing returns. Till then, pretraining had been the key sauce for OpenAI and Google to enhance their fashions.
These pretraining scaling considerations are actually exhibiting up within the knowledge, however the AI trade has discovered different methods to enhance fashions. In 2025, breakthroughs round AI reasoning fashions, which take further time and computational sources to work by means of issues earlier than answering, have pushed the capabilities of AI fashions even additional.
AI labs appear satisfied that scaling up RL and AI reasoning fashions are the brand new frontier. OpenAI researchers beforehand advised TechCrunch that they developed their first AI reasoning mannequin, o1, as a result of they thought it might scale up effectively. Meta and Periodic Labs researchers lately released a paper exploring how RL might scale efficiency additional — a research that reportedly cost more than $4 million, underscoring how costly present approaches stay.
Adaption Labs, in contrast, goals to seek out the subsequent breakthrough, and show that studying from expertise will be far cheaper. The startup was in talks to lift a $20 million to $40 million seed spherical earlier this fall, in keeping with three traders who reviewed its pitch decks. They are saying the spherical has since closed, although the ultimate quantity is unclear. Hooker declined to remark.
“We’re set as much as be very bold,” stated Hooker, when requested about her traders.
Hooker beforehand led Cohere Labs, the place she skilled small AI fashions for enterprise use circumstances. Compact AI programs now routinely outperform their bigger counterparts on coding, math, and reasoning benchmarks — a development Hooker desires to proceed pushing on.
She additionally constructed a repute for broadening entry to AI analysis globally, hiring analysis expertise from underrepresented areas corresponding to Africa. Whereas Adaption Labs will open a San Francisco workplace quickly, Hooker says she plans to rent worldwide.
If Hooker and Adaption Labs are proper in regards to the limitations of scaling, the implications might be large. Billions have already been invested in scaling LLMs, with the idea that larger fashions will result in normal intelligence. But it surely’s potential that true adaptive studying might show not solely extra highly effective — however way more environment friendly.
