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.", "body_md": "[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).\n\nBoth 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).\n\n**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.\n\n**GPT-6 Luna** (`openai/gpt-6-luna`) is the lower-cost option for high-volume agentic workflows, coding, and everyday tasks.\n\nBoth 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.\n\nUse `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.\n\nInstall 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:\n\nThen select `openai/gpt-6-sol` for longer or more demanding coding work, or `openai/gpt-6-luna` when throughput is the priority.\n\nAI Gateway provides a unified API for calling models, tracking usage, and configuring retries, failover, and routing.\n\nTry [GPT-6 Sol](https://vercel.com/ai-gateway/models/gpt-6-sol) or [GPT-6 Luna](https://vercel.com/ai-gateway/models/gpt-6-luna) in the model playground, or [view all language models](https://vercel.com/ai-gateway/models?type=text) available on AI Gateway.", "url": "https://wpnews.pro/news/gpt-6-sol-and-luna-now-available-on-ai-gateway", "canonical_source": "https://vercel.com/changelog/gpt-6-sol-and-luna-now-available-on-ai-gateway", "published_at": "2026-09-22 00:00:00+00:00", "updated_at": "2026-09-23 08:58:58.707173+00:00", "lang": "en", "topics": ["large-language-models", "ai-products", "ai-agents", "ai-tools"], "entities": ["OpenAI", "GPT-6 Sol", "GPT-6 Luna", "GPT-6 Astra", "Vercel", "AI Gateway", "AI SDK", "Vercel CLI"], "alternates": {"html": "https://wpnews.pro/news/gpt-6-sol-and-luna-now-available-on-ai-gateway", "markdown": "https://wpnews.pro/news/gpt-6-sol-and-luna-now-available-on-ai-gateway.md", "text": "https://wpnews.pro/news/gpt-6-sol-and-luna-now-available-on-ai-gateway.txt", "jsonld": "https://wpnews.pro/news/gpt-6-sol-and-luna-now-available-on-ai-gateway.jsonld"}}
