AI BriefingVercel AI Gateway adds Cat Jam reasoning model for coding in stealth
Key point
Cat Jam is free to use during its stealth period and supports function calling and structured outputs for agentic tasks.
Details
Vercel AI Gateway has added Cat Jam, a reasoning model optimized for coding and agentic tasks, available for free during its stealth period. The model features low-latency inference and supports text input only, offering reasoning efforts ranging from low to max.
Capabilities and Integration
Cat Jam supports function calling, allowing agents to connect to external tools, and generates structured outputs that follow a user-supplied JSON schema. Responses include both the model's reasoning text and the final answer. It integrates with the AI SDK, OpenAI-compatible Chat Completions and Responses APIs, Anthropic-compatible Messages API, and coding agents like Claude Code, Codex, and Cursor via the Vercel CLI.
Privacy and Pricing
Zero Data Retention (ZDR) is not available for Cat Jam, and prompts may be retained for safety reasons. AI Gateway reflects provider pricing with no markup and charges no platform fee on inference, including for Bring Your Own Key (BYOK) requests.
