Claude Code now lets you choose Amazon Bedrock service tiers and fixes telemetry and cloud integration bugs.
The latest releases add an ANTHROPIC_BEDROCK_SERVICE_TIER env var that sets the X-Amzn-Bedrock-Service-Tier header, giving you explicit control over default, flex, or priority tiers for Amazon-hosted Claude calls (releases, summary).
OpenTelemetry attributes for api_request/api_error are now properly typed as numbers, with a new claude_code.at_mention event. There are also targeted fixes for Vertex AI/Bedrock structured-output errors, proxy count_tokens failures, and an OAuth 401 loop when betas are disabled releases.
If you’re exploring “lightweight agents,” Routines are getting real use in production-style recurring tasks, without running your own stack guide.
You can now tune Claude-on-Bedrock calls for latency or throughput without code changes, which helps SLOs and cost control.
Telemetry types are corrected, reducing parsing errors and making OTel dashboards more reliable.
-
terminal
Benchmark default vs flex vs priority tiers via ANTHROPIC_BEDROCK_SERVICE_TIER; capture p95 latency, throttling, and any error-rate shifts.
-
terminal
Validate OTel pipelines: ensure numeric attributes ingest as numbers, and surface the new claude_code.at_mention event in dashboards.
Legacy codebase integration strategies...
- 01.
Allowlist and forward X-Amzn-Bedrock-Service-Tier through proxies/gateways; verify egress policies don’t strip it.
- 02.
If you cast OTel attributes from strings, remove workarounds and update schemas; retest Vertex AI/Bedrock structured-output paths and proxy count_tokens.
Fresh architecture paradigms...
- 01.
Parameterize service tier by environment or task class (e.g., priority for interactive PRs, flex for batch jobs).
- 02.
Adopt OTel from day one with numeric attribute types; add alerts on api_error rates and track at_mention resolution.
