GPT-6 Sol and Luna now available on AI Gateway

OpenAI's GPT-6 Sol and GPT-6 Luna are now available on Vercel's AI Gateway, the company said, with both models priced lower than GPT-6 Astra. GPT-6 Sol (openai/gpt-6-sol) targets complex professional workflows and sustained coding tasks, while GPT-6 Luna (openai/gpt-6-luna) is the lower-cost option for high-volume agentic workflows and everyday tasks. Vercel said both models improve factuality and communicate more directly than their GPT-5.6 counterparts, with fewer misleading claims about work completed during coding tasks.

GPT-6 Sol https://vercel.com/ai-gateway/models/gpt-6-sol and GPT-6 Luna https://vercel.com/ai-gateway/models/gpt-6-luna from OpenAI https://vercel.com/ai-gateway/models/providers/openai are now available on AI Gateway https://vercel.com/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 https://vercel.com/ai-gateway/models/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.
