Batches

Portkey lets you run Bedrock batch jobs without any manual S3 wrangling—simply upload an OpenAI-format .jsonl file and Portkey converts it on-the-fly to the Bedrock format. Supported batch endpoints:

Chat Completions (/v1/chat/completions)
Embeddings (/v1/embeddings)

This is the most efficient way to

Test your data with different foundation models
Perform A/B testing with different foundation models
Perform batch inference with different foundation models

Portkey supports two modes on Bedrock:

Provider Batch API (cheapest, completion_window: 24h, 48h, etc.)
Portkey Batch API ⭐️ (fast, provider-agnostic, completion_window: immediate)

Before You Start

Portkey API key ($PORTKEY_API_KEY).
Bedrock credentials — either a Portkey Provider from Model Catalog or explicit AWS keys (aws_access_key_id, aws_secret_access_key, aws_region, optional aws_session_token).
S3 bucket with read/write access for inputs and outputs.
IAM roles (see Permissions & IAM below).
Optional: a Portkey File (input_file_id) — required only when you set completion_window:"immediate" (Portkey-Batch mode).

Defaults & Limits (Bedrock Native)

Property	Default	Notes
`completion_window`	`24h`	Fixed by Bedrock.
Job quota	50k/day	Subject to your AWS account.
Max input file size	10 GB	Across all `.jsonl` objects.

Portkey-Batch mode inherits the Gateway defaults (25 req / 5 s) and retries (3×) per request.

Glossary

Term	Meaning
Batch Job	Collection of asynchronous completions.
Portkey File (`input_file_id`)	File uploaded to Portkey and re-uploaded to the provider for batch processing.
Provider Slug	Bedrock credential stored in Portkey via Model Catalog; referenced by slug.
Completion Window	`immediate` → Portkey-Batch; `24h` → Bedrock native.
