Vercel has made Anthropic's Claude Fable 5.2 available through AI Gateway for open-ended technical work. Vercel says the model improves coding, reasoning and vision over earlier Fable models and can orchestrate smaller models or advise other Claude models on harder problems.

Access requires retaining prompts and completions for 30 days; they are not used to train Claude. Teams with Zero Data Retention enabled receive an error instead of having requests sent to Fable 5.2. The model also has cybersecurity and biology safety classifiers enabled. Developers can configure fallback models when the cybersecurity classifier declines a request.
