Fable and Astra are what we currently call frontier models, but to be more specific they are generalist models, built in pursuit of AGI. The strategy is to have one single model that does everything, whether it's writing code or doing research, etc. Fable is a single, massively sized models that is intended to do specialist work across every domain.

The issue with this is first of all that it is the contradiction of a generalist doing specialist work, and that contradiction creates the present situation with model profiles that ensure that these models will rarely be chosen in a pool of models like V4.1 Flash that can now do GPT 5.4-level work.

We are seeing this reflected in the market where companies and individual developers are moving away from frontier models toward models with better cost profiles. In a sense, the market is killing Anthropic's dreams of AGI.

And there we have it: the reason I say that Anthropic is no longer a frontier lab is because after this July, we have proof that their strategy and the models they put out do not match what us, the users and the market, needs and doesn't fit the work we need models to do. As a result, Anthropic's market share is dropping rapidly, and how can you be a frontier lab when you're losing every day, for months, without end in sight?
