GPT 5.2 Codex now available on Vercel AI Gateway
GPT 5.2 Codex is now accessible through Vercel's AI Gateway without requiring separate provider accounts. This model combines professional knowledge work capabilities with advanced agentic coding features, improved handling of long-running tasks, stronger vision performance, and enhanced cybersecurity capabilities.
You can now access GPT 5.2 Codex with Vercel's and no other provider accounts required. GPT 5.2 Codex combines GPT 5.2's strength in professional knowledge work with GPT 5.1 Codex Max's agentic coding capabilities.AI Gateway
GPT 5.2 Codex is better at working on long running coding tasks compared to predecessors and can handle more complex tasks like large refactors and migrations more reliably. The model has stronger vision performance for more accurate processing of screenshots and charts that are shared while coding. GPT 5.2 Codex also surpasses GPT 5.1 Codex Max in cyber capabilities and outperformed the previous model in OpenAI's Professional Capture-the-Flag (CTF) cybersecurity eval.
