GPT-6 Sol and GPT-6 Luna from OpenAI are now available on AI Gateway.
Both models bring GPT-6 improvements in professional work, coding, computer use, factuality, and communication at a lower price than GPT-6 Astra.
GPT-6 Sol (openai/gpt-6-sol) is suited to complex professional workflows and sustained coding tasks where quality and room to iterate both matter.
GPT-6 Luna (openai/gpt-6-luna) is the lower-cost option for high-volume agentic workflows, coding, and everyday tasks.
Both Sol and Luna communicate more directly than their GPT-5.6 counterparts, with less jargon and fewer low-value details. They also improve factual reliability and are less likely to make misleading claims about work completed during coding tasks.
Use `openai/gpt-6-sol` and `openai/gpt-6-luna` across the [AI SDK](https://vercel.com/docs/ai-gateway/sdks-and-apis/ai-sdk), [OpenAI-compatible Chat Completions API](https://vercel.com/docs/ai-gateway/sdks-and-apis/openai-chat-completions), [OpenAI-compatible Responses API](https://vercel.com/docs/ai-gateway/sdks-and-apis/responses), and [coding agents](https://vercel.com/docs/ai-gateway/coding-agents) connected to AI Gateway.
Install the latest [Vercel CLI](https://vercel.com/docs/cli) and connect your supported [coding agents](https://vercel.com/docs/ai-gateway/coding-agents) to AI Gateway:
Then select openai/gpt-6-sol for longer or more demanding coding work, or openai/gpt-6-luna when throughput is the priority.
AI Gateway provides a unified API for calling models, tracking usage, and configuring retries, failover, and routing.
