All three are stronger at agentic work across coding, biology, and cybersecurity, and are more token-efficient than the previous generation.\n\n**Sol **(`openai/gpt-5.6-sol`\n\n): the flagship, and the most capable of the three.\n\n**Terra **(`openai/gpt-5.6-terra`\n\n): a balanced model for everyday work, with performance comparable to the previous generation at half the cost.\n\n**Luna **(`openai/gpt-5.6-luna`\n\n): a fast, affordable model with strong capability at the lowest cost in the series.\n\nTo use GPT 5.6, set `model`\n\nto one of the above slugs in the [AI SDK](https://ai-sdk.dev/):\n\nYou can also set [routing rules](https://vercel.com/docs/ai-gateway/models-and-providers/routing-rules) to switch to GPT 5.6 from other gateway models without touching your code.\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\nTry GPT 5.6 in the [model playground](https://vercel.com/ai-gateway/models/gpt-5.6-sol).", "url": "https://wpnews.pro/news/gpt-5-6-sol-luna-and-terra-now-available-on-ai-gateway", "canonical_source": "https://vercel.com/changelog/gpt-5-6-now-available-on-ai-gateway", "published_at": "2026-07-09 00:00:00+00:00", "updated_at": "2026-07-09 17:35:58.357397+00:00", "lang": "en", "topics": ["large-language-models", "ai-products", "ai-infrastructure", "developer-tools"], "entities": ["OpenAI", "Vercel", "AI Gateway", "GPT 5.6 Sol", "GPT 5.6 Terra", "GPT 5.6 Luna"], "alternates": {"html": "https://wpnews.pro/news/gpt-5-6-sol-luna-and-terra-now-available-on-ai-gateway", "markdown": "https://wpnews.pro/news/gpt-5-6-sol-luna-and-terra-now-available-on-ai-gateway.md", "text": "https://wpnews.pro/news/gpt-5-6-sol-luna-and-terra-now-available-on-ai-gateway.txt", "jsonld": "https://wpnews.pro/news/gpt-5-6-sol-luna-and-terra-now-available-on-ai-gateway.jsonld"}}
