Is the Gap Widening Between Anthropic and Open-Source Models?

Some developers have told me that the rising costs of frontier AI models from Anthropic and other firms could prompt them to shift to cheaper open-source AI. After all, when companies as sophisticated as Uber are accidentally blowing through their entire year’s AI budget in a matter of months, it makes sense to cut back by using a less capable open-source model to automate simpler tasks. (In fact, companies like Uber and Airbnb are doing exactly that!) It’s not clear whether open-source AI is good enough to meet the challenge, though.
