When using free tiers of Large Language Model (LLM) APIs, developers often encounter HTTP 429 errors, indicating that rate limits have been exceeded. These limits can be based on requests per minute, tokens per minute, requests per day, or concurrency. To effectively manage these errors, it's crucial to read the specific error details provided by the API, such as those from Groq or the Gemini API, which indicate the violated window and offer retry information. Implementing a robust retry strategy with exponential backoff and jitter is essential, but it's also important to recognize when a limit, like a daily cap, cannot be overcome by retries. The most effective long-term solution involves distributing requests across multiple LLM providers, each with their own rate limits, and routing requests based on the specific limit shape required for the task.
