Mercury 3 now available on AI Gateway Vercel added Inception's Mercury 3 to its AI Gateway with 50% off launch pricing, calling the model via the name `inception/mercury-3`. Inception reports generation speeds above 1,000 tokens per second and a 1M-token context window for Mercury 3, which uses diffusion to generate text through parallel refinement and targets latency-sensitive workloads such as browser agents, real-time search, interactive education and customer support. AI Gateway provides a unified API for calling models, tracking usage and cost, and configuring retries, failover and performance optimizations, and reflects provider pricing with no markup and no platform fee on inference, including Bring Your Own Key requests. Mercury 3 from Inception https://vercel.com/ai-gateway/models/mercury-3 is now available on AI Gateway with 50% off launch pricing. Inception reports strong results across a range of benchmarks, with generation speeds above 1,000 tokens per second. Mercury 3 uses diffusion to generate text through parallel refinement. It brings improved reasoning to latency-sensitive workloads such as browser agents, real-time search, interactive education, and customer support. A 1M-token context window gives those applications room for long documents and extended conversation histories. Set AI GATEWAY API KEY in your environment. Use inception/mercury-3 as the model name: To use it in Claude Code, Codex, Cursor, and more, install the latest Vercel CLI and run setup: Then select inception/mercury-3 in the agent. See the coding agents guide https://vercel.com/docs/ai-gateway/coding-agents for details. Try Mercury 3 in the model playground https://vercel.com/ai-gateway/models/mercury-3 .
