AI labs are racing to construct information facilities as giant as Manhattan, every costing billions of {dollars} and consuming as a lot power as a small metropolis. The hassle is pushed by a deep perception in “scaling” — the concept including extra computing energy to present AI coaching strategies will ultimately yield superintelligent methods able to performing all types of duties.
However a rising refrain of AI researchers say the scaling of huge language fashions could also be reaching its limits, and that different breakthroughs could also be wanted to enhance AI efficiency.
That’s the guess 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 grow to be an inefficient method to squeeze extra efficiency out of AI fashions. Hooker, who left Cohere in August, quietly introduced the startup this month to begin recruiting extra broadly.
In an interview with TechCrunch, Hooker says Adaption Labs is constructing AI methods that may repeatedly adapt and study from their real-world experiences, and accomplish that extraordinarily effectively. She declined to share particulars concerning the strategies behind this strategy 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 formulation 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 rigorously round it subsequent time. AI labs have tried to seize this concept by reinforcement studying (RL), which permits AI fashions to study from their errors in managed settings. Nonetheless, at this time’s RL strategies don’t assist AI fashions in manufacturing — which means methods already being utilized by clients — study from their errors in actual time. They simply preserve stubbing their toe.
Some AI labs supply consulting providers to assist enterprises fine-tune their AI fashions to their customized wants, nevertheless it comes at a value. OpenAI reportedly requires clients to spend upwards of $10 million with the corporate to supply its consulting providers on fine-tuning.

“We have now a handful of frontier labs that decide this set of AI fashions which are served the identical method to everybody, they usually’re very costly to adapt,” stated Hooker. “And truly, I feel that doesn’t have to be true anymore, and AI methods can very effectively study from an atmosphere. Proving that can 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 business’s religion in scaling LLMs is wavering. A latest paper from MIT researchers discovered that the world’s largest AI fashions could quickly present diminishing returns. The vibes in San Francisco appear to be shifting, too. The AI world’s favourite podcaster, Dwarkesh Patel, just 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 really 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 concerning the longterm potential of RL to enhance AI fashions.
These kind of fears aren’t unprecedented. In late 2024, some AI researchers raised issues that scaling AI fashions by pretraining — by which 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 issues at the moment are displaying up within the information, however the AI business has discovered different methods to enhance fashions. In 2025, breakthroughs round AI reasoning fashions, which take further time and computational sources to work by 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 could scale up effectively. Meta and Periodic Labs researchers just lately launched a paper exploring how RL may scale efficiency additional — a research that reportedly value greater than $4 million, underscoring how costly present approaches stay.
Adaption Labs, in contrast, goals to search out the following breakthrough, and show that studying from expertise may 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 formidable,” stated Hooker, when requested about her traders.
Hooker beforehand led Cohere Labs, the place she skilled small AI fashions for enterprise use instances. Compact AI methods now routinely outperform their bigger counterparts on coding, math, and reasoning benchmarks — a development Hooker desires to proceed pushing on.
She additionally constructed a fame for broadening entry to AI analysis globally, hiring analysis expertise from underrepresented areas comparable 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 concerning the limitations of scaling, the implications may very well be large. Billions have already been invested in scaling LLMs, with the belief that greater fashions will result in normal intelligence. However it’s doable that true adaptive studying may show not solely extra highly effective — however way more environment friendly.
