AI labs are racing to construct knowledge facilities as giant 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 that including extra computing energy to current AI coaching strategies will finally yield superintelligent techniques able to performing all types 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 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 that scaling LLMs has turn into an inefficient technique 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 iinfoai, Hooker says Adaption Labs is constructing AI techniques that may repeatedly adapt and be taught from their real-world experiences, and accomplish that extraordinarily effectively. She declined to share particulars in regards to 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 system 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,” mentioned Hooker.
Adapting is the “coronary heart of studying,” in keeping with Hooker. For instance, stub your toe once you stroll previous your eating room desk, and also you’ll be taught to step extra fastidiously round it subsequent time. AI labs have tried to seize this concept via reinforcement studying (RL), which permits AI fashions to be taught from their errors in managed settings. Nonetheless, right now’s RL strategies don’t assist AI fashions in manufacturing — that means techniques already being utilized by prospects — to be taught from their errors in actual time. They simply maintain 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 prospects to spend upward 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 can be served the identical technique to everybody, and so they’re very costly to adapt,” mentioned Hooker. “And truly, I feel that doesn’t have to be true anymore, and AI techniques can very effectively be taught from an atmosphere. Proving that can utterly change the dynamics of who will get to manage and form AI, and actually, who these fashions serve on the finish of the day.”
Adaption Labs is the newest 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 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 considered “the daddy of RL,” informed Patel in September that LLMs can’t really scale as a result of they don’t be taught from real-world expertise. This month, early OpenAI worker Andrej Karpathy informed Patel he had reservations in regards to the long-term 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 via pretraining — through which AI fashions be taught 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 assets to work via 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 informed iinfoai 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 just lately launched a paper exploring how RL may scale efficiency additional — a examine that reportedly price greater than $4 million, underscoring how costly present approaches stay.
Adaption Labs, against this, goals to seek out the subsequent breakthrough and show that studying from expertise might be far cheaper. The startup was in talks to boost 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,” mentioned Hooker, when requested about her traders.
Hooker beforehand led Cohere Labs, the place she educated small AI fashions for enterprise use instances. Compact AI techniques now routinely outperform their bigger counterparts on coding, math, and reasoning benchmarks — a pattern Hooker desires to proceed pushing on.
She additionally constructed a status for broadening entry to AI analysis globally, hiring analysis expertise from underrepresented areas akin 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 big. Billions have already been invested in scaling LLMs, with the belief that larger fashions will result in common intelligence. However it’s doable that true adaptive studying may show not solely extra highly effective — however way more environment friendly.
