Sessions cannot be paused or resumed, and an AWS account with IAM set-up is needed before a first call.\n\n**Freestyle.** A public OpenAPI 3.1 file describes 88 operations with a stable error code on every failure, and per-VM identity tokens keep the team API key away from end users. No terms of service, product privacy policy, request rate limit or incident history was found, and the only SDK is TypeScript.\n\n## Before you call either\n\n### Amazon Bedrock AgentCore Code Interpreter\n\n1. Start a session with `StartCodeInterpreterSession`, then pass its id in the `x-amzn-code-interpreter-session-id` header on every `InvokeCodeInterpreter` call\n2. Set `sessionTimeoutSeconds` when starting. The default is 900 seconds and the maximum is eight hours, and the session ends itself at the timeout\n3. Stop sessions when done. Billing runs per second while code is busy, and a session left open counts against the 1,000 concurrent-session quota\n4. Use `startCommandExecution`, `getTask` and `stopTask` for work longer than the 15-minute synchronous request limit\n5. Retry `ThrottlingException` (429) and `InternalServerException` (500) with exponential backoff, and treat `ServiceQuotaExceededException`, returned as HTTP 402, as a quota to raise\n\n### Freestyle\n\n1. Send a `firewall` object on every `POST /v5/vms`. It is required, and a VM with no rules has no outbound internet\n2. Ask the owner to run `freestyle login` in a browser once, then mint a key with `freestyle tokens create --output json`\n3. Do not retry an exec that answers 409 `VM_NON_RESPONSIVE`. The command may already have run\n4. Keep `exec-await` under its 300,000 ms cap and use a PTY session or `x-freestyle-background-after-secs` for longer work\n5. Call the `/v5` paths. The unversioned duplicates in the OpenAPI file are marked deprecated\n\n## Questions\n\n### Which is better for AI agents, Amazon Bedrock AgentCore Code Interpreter or Freestyle?\n\nAmazon Bedrock AgentCore Code Interpreter scores 73.1 (BB) on agent readiness against Freestyle's 58.5 (C), and leads in 4 of 7 scored categories. Freestyle leads on schema \u0026 documentation, payments \u0026 pricing and maintenance \u0026 community.\n\n### Do Amazon Bedrock AgentCore Code Interpreter and Freestyle need an API key?\n\nBoth need an API key.\n\n### Can an agent call Amazon Bedrock AgentCore Code Interpreter and Freestyle without installing anything?\n\nYes.
