Portkey supports batching requests in two ways:
  1. Batching requests with Provider’s batch API using unified api and provider file
  2. Custom batching with Portkey’s batch API

​
1. Batching requests directly with Provider’s batch API using unified api

Portkey supports batching requests directly with Provider’s batch API by using a unified api structure. The unified api structure is similar to OpenAI’s batch API. Please refer to individual provider’s documentation for more details if additional headers or parameters are required.

2. Custom batching with Portkey’s batch API

Portkey supports custom batching with Portkey’s batch API in two ways.
  1. Batching requests with Provider’s batch API using Portkey’s file.
  2. Batching requests directly with Portkey’s gateway using Portkey’s file.
This is controlled by completion_window parameter in the request.
  • When completion_window is set to 24h, Portkey will batch requests with Provider’s batch API using Portkey’s file.
  • When completion_window is set to immediate, Portkey will batch requests directly with Portkey’s gateway.
Along with this, you have to set portkey_options which helps Portkey to batch requests to Provider’s batch API or Gateway.
  • This is achieved by using provider specific headers in the portkey_options
    • For example, if you want to use OpenAI’s batch API, you can set portkey_options to {"x-portkey-virtual-key": "openai-virtual_key"}

​
2.1 Batching requests with Provider’s batch API using Portkey’s file

completion_window needs to be set to 24h and input_file_id needs to be Portkey’s file id. Please refer to Portkey’s files for more details.
  • Using Portkey’s file, you can upload your data to Portkey and reuse the content in your requests.
  • Portkey will automatically upload the file to the Provider and reuse the content in your batch requests.
  • Portkey will also automatically check the batch progress and does post batch request analysis including token and cost calculations.
  • You can also get the batch output in the response using GET /batches/<batch_id>/output endpoint.

​
2.2 Batching requests directly with Portkey’s gateway

completion_window needs to be set to immediate and input_file_id needs to be Portkey’s file id. Please refer to Portkey’s files for more details.
Using this method, you can batch requests to any provider, whether they support batching or not.
  • Portkey will batch requests directly with Portkey’s gateway.
  • Please note the following:
    • Currently, Batch Size is set to 25 by default.
    • Batch Interval / Reset is set to 5 seconds (Next batch runs after 5 seconds)
    • We retry requests 3 times by default (can be extended retry using x-portkey-config header with retry)
    • We have plans to support custom batch size, batch interval and retry count in the future.
  • Portkey will also automatically check the batch progress and does post batch request analysis including token and cost calculations.
