Tips for Success
According to OpenAI
- Be Specific: The more detailed your prompt, the better Codex’s output. For example, specify the programming language or constraints like “optimise for speed.”
- Check Rate Limits: API usage is subject to rate limits, so monitor your quota in the OpenAI dashboard.
- Explore Options: Run codex — help to see all available commands and flags, like setting output formats or model preferences.
