Fix ContextWindowExceededError
in LiteLLM
✅ Solution
The ContextWindowExceededError in litellm usually occurs when the total length of your prompt and generated response exceeds the model's maximum context window. To fix this, shorten your prompt, use a model with a larger context window, or implement techniques like summarization or context pruning to reduce the total token count sent to the model. Also verify that your model's context window is properly set in your code and is not using arbitrary defaults.
