GPT-6.1 Sol from OpenAI now available on Vercel AI Gateway

What happened

Vercel has made GPT-6.1 Sol from OpenAI available on AI Gateway. The model improves upon GPT-6 Sol and is optimized for coding tasks, computer use, and professional workflows that involve document analysis and multi-step operations.

How to use GPT-6.1 Sol

Developers can access GPT-6.1 Sol through multiple interfaces on Vercel's platform. The model identifier is openai/gpt-6.1-sol and works across the AI SDK, OpenAI-compatible Chat Completions API, and Responses API. For those using coding agents connected to AI Gateway, such as Codex, Cursor, and similar tools, the latest Vercel CLI must be installed followed by running the setup command.

• Use model name openai/gpt-6.1-sol in any compatible SDK
• Install latest Vercel CLI with npm i -g vercel@latest
• Run vercel ai-gateway setup to configure for coding agents
• Select the model from agent settings

npm i -g vercel@latest

Pricing and use cases

GPT-6.1 Sol offers pricing advantages in two areas. Standard input and output costs are lower than GPT-6 Astra, making routine requests more economical. Cached input pricing is particularly cost-effective, which benefits workflows that reuse long shared context across multiple requests. This pricing structure makes the model practical for agents that debug code, process business tasks, or extract information from PDFs with complex layouts including tables and charts.

Integration with agents

Developers working with coding agents can integrate GPT-6.1 Sol by installing the latest Vercel CLI and running the ai-gateway setup command. Once configured, the model appears as an option within supported agents. Vercel provides a playground for testing the model and additional documentation about the GPT-6 model family for further reference.

Developer implications

Teams using Vercel's AI Gateway can now route model calls for coding tasks and complex workflows through a single unified endpoint. The combination of improved performance on coding and document analysis tasks with competitive pricing makes GPT-6.1 Sol a practical choice for builders implementing AI agents that need to debug, analyze, or extract information from structured data. Existing users of AI Gateway can adopt the model by selecting it in their agent configuration without changes to deployment infrastructure.
