Inception reports strong results across a range of benchmarks, with generation speeds above 1,000 tokens per second.\n\nMercury 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.\n\nSet `AI_GATEWAY_API_KEY` in your environment. Use `inception/mercury-3` as the model name:\n\nTo use it in Claude Code, Codex, Cursor, and more, install the latest Vercel CLI and run setup:\n\nThen select `inception/mercury-3` in the agent. See the [coding agents guide](https://vercel.com/docs/ai-gateway/coding-agents) for details.\n\nTry Mercury 3 in the [model playground](https://vercel.com/ai-gateway/models/mercury-3).\n\nAI Gateway provides a unified API for calling models, tracking usage and cost, and configuring retries, failover, and performance optimizations for higher-than-provider uptime. It includes built-in [custom reporting](https://vercel.com/changelog/custom-reporting-ai-gateway), [Zero Data Retention support](https://vercel.com/blog/zdr-on-ai-gateway), [budgets for API keys](https://vercel.com/docs/ai-gateway/authentication-and-byok/api-keys), [routing rules](https://vercel.com/docs/ai-gateway/models-and-providers/routing-rules), and more.\n\nAI Gateway reflects provider pricing with no markup and does not charge a platform fee on inference, including on [Bring Your Own Key](https://vercel.com/docs/ai-gateway/authentication-and-byok/byok) (BYOK) requests.\n\nYou can view [all language models](https://vercel.com/ai-gateway/models?type=text) available on AI Gateway.", "url": "https://wpnews.pro/news/mercury-3-now-available-on-ai-gateway", "canonical_source": "https://vercel.com/changelog/mercury-3-now-available-on-ai-gateway", "published_at": "2026-10-19 00:00:00+00:00", "updated_at": "2026-10-19 17:44:50.507443+00:00", "lang": "en", "topics": ["large-language-models", "ai-infrastructure", "ai-agents", "ai-tools"], "entities": ["Vercel", "Inception", "Mercury 3", "AI Gateway", "Claude Code", "Codex", "Cursor", "Vercel CLI"], "also_reported_by": [], "alternates": {"html": "https://wpnews.pro/news/mercury-3-now-available-on-ai-gateway", "markdown": "https://wpnews.pro/news/mercury-3-now-available-on-ai-gateway.md", "text": "https://wpnews.pro/news/mercury-3-now-available-on-ai-gateway.txt", "jsonld": "https://wpnews.pro/news/mercury-3-now-available-on-ai-gateway.jsonld"}}
