Initial impressions of Claude Fable 5
The article gives early hands-on impressions of Anthropic's Claude Fable 5, describing it as very capable but also slow and expensive. It highlights a 1 million token context window, a 128,000-token output limit, stricter safety guardrails than Claude Mythos 5, and a new fallback mechanism when requests are rejected.
