Claude Opus 5.5 and Sonnet 5.5 available on Amazon Bedrock in AWS GovCloud (US) with Claude Code

Anthropic’s Claude Opus 5.5 and Claude Sonnet 5.5 (alongside Claude Sonnet 5) are available via Amazon Bedrock in AWS GovCloud (US); Sonnet 5 holds FedRAMP Class D and DoD IL4/IL5 authorizations and Opus/Sonnet 5.5 hold FedRAMP Class D certification on Bedrock (users should verify current model certification status). The post outlines using Anthropic’s agentic coding tool Claude Code with Bedrock’s bedrock-runtime and bedrock-mantle endpoints, describing security features (Zero Operator Access), compliance pathways, and integrations for CI/CD and developer tooling.

Anthropic launches Claude Haiku 5.5 with big price cuts and benchmark gains

Anthropic released Claude Haiku 5.5, a faster, lower‑cost small model aimed at high‑volume tasks; Anthropic says Haiku 5.5 costs ~75% less on average than Haiku 4.5 and up to 90% less for prompts ≤100,000 tokens. The company also halved Sonnet 5.5 cache‑read costs, added monthly API credits for subscribers, updated SDKs with beta computer/browser use, and says Haiku 5.5 outperforms its predecessor (and compares favorably to OpenAI’s GPT‑6 Luna) on several benchmarks and agentic coding tests.

Anthropic releases Claude Sonnet 5.5 claiming faster output and up to 30% lower per-task costs

Anthropic has released Claude Sonnet 5.5, the second model in its Claude 5.5 family; the company says the model generates output more than 30% faster and reduces per-task costs by up to 30% through more efficient token usage while nearly matching Opus 5.5 on several coding and knowledge-work benchmarks. Sonnet 5.5 is available on AWS, Google Cloud, and Azure as model ID "claude-sonnet-5-5," and Anthropic says it adds new safeguards against cybersecurity risks and distillation attacks — independent verification of the performance and cost claims is pending.

Anthropic releases Opus 5.5 with improved performance and lower pricing

Anthropic announced Opus 5.5, a faster and cheaper follow-up to Opus 5 that the company says outperforms the larger Fable model on many coding and knowledge-work benchmarks. Output token pricing has been reduced (now $20 per mTok vs $25 for Opus 5), the model communicates with less jargon and front-loads key information, and Sonnet 5.5 and Haiku 5.5 are slated to follow soon; the release is subject to the same safety safeguards as Fable and underwent external evaluation.
