Model added: Claude Fable 5 joins the Opera Neon model lineup
Claude Fable 5 is now available in Chat for Opera Neon subscribers.
Anthropic released Fable 5 on June 9 — their most capable model made publicly available to date. It's built for extended agentic work, handles software engineering, scientific research, and vision at state-of-the-art levels, and sits just below the yet unreleased Mythos 5 in raw capability.
Neon is model-agnostic, and Fable 5 takes its place alongside the best versions of every other major family — Gemini 3.5 Flash, GPT-5.5 and GPT-5.4 Pro, GROK 4.3, and more. Pick your model, run your agent.
Love to see what you do with it. Tell us how it works in the comments.
