Anthropic dropped two models today.

Most people are focused on the wrong one.

What launched:

Fable 5 — the public-facing Mythos-class model. Available on Pro, Max, Team, and Enterprise right now. Stronger than anything Anthropic has released publicly.

Better at long-context, agentic coding, vision, and knowledge work. The longer and more complex the task, the bigger the gap between Fable and previous models.
