Amazon Bedrock AgentCore Code Interpreter vs Sprites

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.

Sprites

A Sprite keeps a 100 GB ext4 disk between runs, bills compute only while active and can be checkpointed and restored through a published OpenAPI contract. The status page records four Sprites incidents in the last 90 days, one lasting over seven hours, and outbound network access is unrestricted until a policy is set.

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

Sprites

1. Create a token at sprites.dev/account after a browser signup, and send it as Authorization: Bearer <token> to https://api.sprites.dev
2. Follow the OpenAPI document, not the product page example. Create with POST /v1/sprites and a JSON name, and run commands with POST /v1/sprites/{name}/exec using cmd query parameters
3. Set a network policy with POST /v1/sprites/{name}/policy/network before running untrusted code. Egress is open until one is set
4. Processes started by exec stop on a cold wake. Define a Service for anything that must answer the request that wakes the Sprite
5. Create a checkpoint before a restore. Restoring replaces the filesystem, ends active sessions and keeps no copy of the replaced state
6. Sprite creation is limited to 10 a minute on pay-as-you-go. The Go SDK reads Retry-After and the error code sprite_creation_rate_limited on a 429
7. Delete Sprites you no longer need. An idle Sprite still bills cold storage for the bytes it holds
