They can't do that because only they are the incorruptible stewards empowered with the ability to develop these models, making them accessible to the unwashed masses would be irresponsible!
If that was true, they wouldn't have named it Gemini 1.5 to follow the half-point increment of ChatGPT, they desperately want "people" to care about their product to gain back their mindshare.
Anthropic's Claude targets mostly business use cases and you don't see them write self-congratulating articles about Claude v2.1, they just pushed the product.
And look at how well it's going for Claude. Their primary claim to fame is being called "an annoying coworker" and that's it.
Why would anyone look to form a contract with Anthropic right now? I'd say they're in danger here, because their models and offerings don't have clear value propositions to customers.
I work at a very large company and everyone knows about ChatGPT and Gemini (in part because we for our sins have a good chunk of GCP stuff), but I doubt anyone here not doing some LLM-flavored development has ever even heard of Anthropic, let alone Claude.
