# MODEL_RATE_LIMIT

<Note>
  Currently only used in `langchainjs` (JavaScript/TypeScript).
</Note>

You have hit the maximum number of requests that a model provider allows over a given time period and are being temporarily blocked.

This error occurs when you exceed the maximum number of requests permitted by your model provider within a specific timeframe, resulting in temporary blocking. The restriction is generally temporary and lifts after the limit resets.

## Troubleshooting

To resolve this error, you can:

1. **Implement Rate Limiting**: Deploy a rate limiter to regulate the frequency of requests sent to the model.

2. **Implement Response Caching**: Use model response caching to reduce redundant requests when incoming queries are repetitive.

3. **Use Multiple Providers**: Distribute requests across multiple providers if your application architecture supports this approach

4. **Contact Your Provider**: Reach out to your model provider requesting an increase to your rate limits
