Compare it with Opus on the same tasks and reasoning settings before choosing it. Use the current proof and benchmark evidence on this page for measured standing. The data layer withholds a suspect latency figure, so that figure cannot establish suitability for interactive work. ### Strengths - Tool use and structured outputs are listed in the accepted record - Cache and batch pricing are recorded separately ### Weaknesses - Measure latency on your own prompts; the withheld figure is not usable evidence - Compare tokenizer counts on the actual text rather than assuming identical token bills across models ### Reach for it when - Evaluation for difficult agent tasks - Workflows that can measure quality and cost per completed task ### Avoid it if - Your application requires a latency guarantee you have not tested - A less expensive candidate already passes your evaluations Sources: [platform.claude.com](https://platform.claude.com/docs/en/about-claude/pricing) · [platform.claude.com](https://platform.claude.com/docs/en/about-claude/models/overview) Claude Fable 5 is a Mythos-class model from Anthropic, built for autonomous knowledge work and coding.
