**A · 81.7/100 · rank #8 of 1486 · #3 in Model APIs & inference · agent-ready · confidence medium**


Assessment: Bedrock reaches Claude, GPT-6, Nova, Llama and other families through one IAM-controlled API, with a 99.9 per cent SLA and a per-Region zero-retention switch. Setup needs an AWS account, IAM permissions and a Region, capabilities vary by model, and some Regions gave five older Claude models about 34 days of notice.

## Facts

- Kind: Model API · vendor: Amazon Web Services · category: Model APIs & inference · legal entity: Amazon Web Services, Inc. · provenance 94/100
- Endpoint: `https://bedrock-runtime.us-east-1.amazonaws.com` (HTTP)
- Auth: OAuth or key · pricing: Pay per use · x402: no · licence: Proprietary service under the AWS Customer Agreement and Service Terms. Third-party models carry their providers' licence terms. The AWS SDKs and the Smithy service models are Apache-2.0
- Benchmark probes: not run yet, so Performance is pending
- Live, from our pollers (not part of the score): up at 2026-11-07 17:49 UTC · uptime 30 days 100.0% (195 probes) · p50 269 ms · p95 352 ms over 24 hours
- Surface listed: Model inference on the bedrock-runtime and bedrock-mantle endpoints (Converse, InvokeModel, Responses, Chat Completions and Messages). Bedrock Guardrails, model customisation and AgentCore are separate listings (amazon-bedrock-guardrails, amazon-bedrock-customization, agentcore-*). Read from AWS's docs, pricing, price feed and health history on 6 November 2026; no account was made
- Free tier: No Bedrock free tier. New AWS accounts get up to $200 in credits, and the Free Tier page lists Bedrock among eligible services
- Trains on API data: No. The security page says customer data isn't shared with model providers or used to improve the base models
- Data retention: Not stored by default. Claude Fable 5 and 5.1 keep all traffic up to 30 days, GPT-6 and GPT-5.x models keep classifier-flagged traffic up to 30 days
- Zero data retention: `data_retention_mode: none` per Region or per project, which blocks models that require retention. Zero retention for Claude Fable 5 and 5.1 is granted only through the Enterprise Frontier Safeguards programme
- Rate limits: Per-model tokens a minute per Region, published in the AWS General Reference and adjustable in Service Quotas, plus a cross-model tokens-per-day quota
- Endpoints: `bedrock-runtime` (Converse, InvokeModel, Responses, Chat Completions) and `bedrock-mantle` (OpenAI- and Anthropic-compatible, projects)
- Batch: 50% off on supported models, not shown for Opus 5.5 or Sonnet 5.5. Since 26 October 2026 the docs say on-demand requests take priority over batch jobs, completion isn't guaranteed and jobs time out after 24 hours by default, up to 168
- Service tiers: Standard, Priority (Nova 2 Lite at 1.75x), Flex (half price) and Reserved
- Certifications: ISO, SOC and CSA STAR Level 2 scope, HIPAA eligible, FedRAMP High in GovCloud (US-West), per the Bedrock security page
- Status: AWS Health Dashboard with per-Region Bedrock feeds
- Models ($/1M in/out): `anthropic.claude-opus-5-5` $4/$20; `anthropic.claude-sonnet-5-5` $2/$10; `anthropic.claude-fable-5-1` $11/$55; `amazon.nova-2-lite-v1` $0.30/$2.50
- 2026-10-08 Price change: Claude Opus 4.1 enters public extended access at higher prices
- 2026-10-14 Shutdown: Claude Sonnet 4 (`anthropic.claude-sonnet-4-20250514-v1:0`) end of life
- 2026-11-26 Shutdown: AI21 Jamba 1.5 Large and Mini end of life
- 2026-11-30 Shutdown: TwelveLabs Marengo Embed v2.7 end of life
- 2027-01-08 Shutdown: Claude Opus 4.1 end of life

- Scores: Reliability 80, Performance pending, Schema & documentation 94, Agent ergonomics 92, Security & auth 98, Payments & pricing 30, Task success pending, Maintenance & community 81, Transparency & trust 85 · total over the 7 assessed categories
- Why: Reliability, AWS Health Dashboard with per-service, per-Region feeds and a public history file (20). · Schema & documentation, Model reading. · Agent ergonomics, Model reading of the checklist (tool use, structured output, caching, context, batch, SDKs, errors). · Security & auth, Model reading. · Payments & pricing, No x402, MPP or L402 (0). · Maintenance & community, Model reading. · Transparency & trust, Closed service under the AWS Customer Agreement and Service Terms, with the SDKs and Smithy models under Apache-2.0 (18, as for S3).

## Before you call it

1. Use the geographic or global inference ID from the model card, such as `global.anthropic.claude-opus-5-5`. Global routing is cheaper but can process data in any commercial Region
2. Set `data_retention_mode` to `none` in each Region before sending sensitive data. Models that need retention then return ValidationException
3. Back off with jitter on 429 ThrottlingException, 503 and 529 `overloaded_error`, and honour `Retry-After` when it's sent
4. Generate short-term API keys from an IAM role for production. Long-term keys create an IAM user and AWS marks them exploration only
5. Call ListFoundationModels in your Region and read `modelLifecycle` before pinning a model ID. Claude 3.x IDs in several Regions stop working on 13 November 2026 and requests don't redirect

## Connect

```bash
