Use OpenAI Developers to build AI applications and agents. Optimize your existing API integration with our latest models and best practices, and build multimodal experiences with voice and image models. Build agents with the Agents API and OpenAI-hosted sandboxes, and create voice agents with the new GPT Live bidirectional model. Get best practices to improve your prompts and diagnose API errors. Plan your DevDay with official event information and session guidance.
Example prompts
- “Create an OpenAI API key to use in this project”
- “Build an agent with the Agents API”
- “Help me diagnose an API error”
Skills
agents
Build agent apps with the Agents API or Agents SDK. Use when adding tools, sessions, sandboxes, handoffs, guardrails, evals, or deployment.
devday-guide
Help with OpenAI DevDay attendance, onsite logistics, session schedules, personal plans, livestreams, recordings, and DevDay Exchanges. Use for DevDay-specific questions, not general OpenAI API or app development.
openai-api-troubleshooting
Use when an OpenAI API request fails and Codex needs to classify the likely cause, explain the next step, and route to the right follow-up. Covers common runtime failures such as blocked outbound network access, invalid credentials, exhausted API quota or credits, rate limits, and model, project, or organization access issues; delegate key provisioning to openai-platform-api-key and current documentation lookups to openai-docs.
openai-platform-api-key
Use when Codex is asked to build, run, test, debug, or configure an OpenAI-backed or provider-unspecified AI app, UI, script, CLI, generator, or tool, especially requests phrased only as "using AI" or generators driven by forms/user input; also use for OPENAI_API_KEY or sk-proj setup. Treat this as the credential gate: inspect safely, ask reuse-vs-new before API work, and never expose plaintext.
