The bitter lesson for generative AI adoption



The speedy tempo of innovation and the proliferation of recent fashions have raised considerations about know-how lock-in. Lock-in happens when companies change into overly reliant on a particular mannequin with bespoke scaffolding that limits their capacity to adapt to improvements. Upon its launch, GPT-4 was the identical price as GPT-3 regardless of being a superior mannequin with a lot greater efficiency. Because the GPT-4 launch in March 2023, OpenAI costs have fallen one other six instances for enter knowledge and 4 instances for output knowledge with GPT-4o, launched Could 13, 2024. In fact, an evaluation of this type assumes that era is bought at price or a hard and fast revenue, which might be not true, and important capital injections and detrimental margins for capturing market share have doubtless sponsored a few of this. Nevertheless, we doubt these levers clarify all the development features and worth reductions. Even Gemini 1.5 Flash, launched Could 24, 2024, provides efficiency close to GPT-4, costing about 85 instances much less for enter knowledge and 57 instances much less for output knowledge than the unique GPT-4. Though eliminating know-how lock-in is probably not attainable, companies can cut back their grip on know-how adoption through the use of business fashions within the quick run.

Avoiding lock-in dangers

In some respects, the bitter lesson is a part of this extra appreciable dialogue about lock-in dangers. We count on scaling to proceed, a minimum of for one more couple of interactions. Until you could have a specific use case with apparent business potential, or function inside a high-risk and extremely regulated business, adopting the know-how earlier than the complete scaling potential is set and exhausted could also be hasty.

In the end, coaching a language mannequin or adopting an open-source mannequin is like swapping a leash for a ball and chain. Both approach, you’re not strolling away with out leaving some pores and skin within the recreation. Chances are you’ll want to coach or tune a mannequin in a slender area with specialised language and tail information. Nevertheless, coaching language fashions entails substantial time, computational assets, and monetary funding. This will increase the danger for any technique. Coaching a language mannequin can price a whole bunch of hundreds to hundreds of thousands of {dollars}, relying on the mannequin’s dimension and the quantity of coaching knowledge. The financial burden is exacerbated by the nonlinear scaling legal guidelines of mannequin coaching, during which features in efficiency might require exponentially better compute assets—highlighting the uncertainty and threat concerned in such endeavors. Bloomberg’s technique of together with a margin of error of 30 % of their computing price range underscores the unpredictable nature of coaching.
