Which one, for what

Amazon Bedrock AgentCore Code Interpreter BB

Good for A team already on AWS that wants agent code to run under IAM, inside a VPC and beside S3 data, for sessions up to eight hours.

Ahead on

  • Reliability, 85 against 70
  • Agent ergonomics, 75 against 65
  • Security & auth, 87 against 80

Also in its favour

  • Agent-ready, a grade of BB or better
  • Free to start without a card

Watch for

No pause, resume or snapshot. Session files are removed when the session ends, and persistence needs a customer-owned S3 Files or EFS mount inside a VPC

Vercel Sandbox B

Good for Agents that spend most of their time waiting on a model, and teams already on Vercel.

Ahead on

  • Payments & pricing, 40 against 30
  • Maintenance & community, 80 against 65
  • Transparency & trust, 75 against 70

Watch for

Tied to a Vercel team and project even when called from elsewhere, and access tokens reach the whole team

Verdicts

Amazon Bedrock AgentCore Code Interpreter

Each session runs in its own microVM with 2 vCPU, 8 GB and a 10 GB disk for up to eight hours, and IAM can scope access to one interpreter. Sessions cannot be paused or resumed, and an AWS account with IAM set-up is needed before a first call.

Vercel Sandbox

Active CPU billing, so waiting on model responses costs only memory. Tied to a Vercel team and project even when called from elsewhere, and access tokens reach the whole team.

Before you call either

Amazon Bedrock AgentCore Code Interpreter

  1. Start a session with StartCodeInterpreterSession, then pass its id in the x-amzn-code-interpreter-session-id header on every InvokeCodeInterpreter call
  2. Set sessionTimeoutSeconds when starting. The default is 900 seconds and the maximum is eight hours, and the session ends itself at the timeout
  3. 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
  4. Use startCommandExecution, getTask and stopTask for work longer than the 15-minute synchronous request limit
  5. Retry ThrottlingException (429) and InternalServerException (500) with exponential backoff, and treat ServiceQuotaExceededException, returned as HTTP 402, as a quota to raise

Vercel Sandbox

  1. Call sandbox.stop() when the task is done. Memory bills until the session ends
  2. Use Sandbox.getOrCreate with a name so retries land in the same sandbox
  3. Set networkPolicy to deny-all for untrusted code. The default is allow-all
  4. Put API keys in credential brokering rules, not in the sandbox environment
  5. Pass persistent: false for one-off runs so no snapshot is stored or billed
