Claude Platform — April 16, 2026 — Opus 4.7 launches + Bedrock GA
Claude Platform — April 16, 2026
Two announcements for API developers. Claude Opus 4.7 is generally available at Opus 4.6 pricing, but ships with breaking API changes: thinking budgets removed, temperature/top_p/top_k now 400s on non-default values, thinking silently omitted by default, and a new tokenizer. Separately, Claude in Amazon Bedrock opens to every Bedrock customer across 27 AWS regions through a new Messages API endpoint at /anthropic/v1/messages — zero operator access from Anthropic, AWS-managed infrastructure.
Claude Opus 4.7 GA with breaking API changes
Why: Developers running complex agentic coding and vision workloads needed better reasoning without paying more, but thinking and sampling APIs required a migration.
What: Launches claude-opus-4-7 generally available at Opus 4.6 pricing ($5/$25 per MTok), with a new tokenizer, high-resolution image support, and breaking API changes.
How: Set model: "claude-opus-4-7", drop temperature/top_p/top_k, switch thinking to {"type": "adaptive"}, and review the migration guide before cutting over.
Claude in Amazon Bedrock — open to all customers
Why: AWS-heavy customers needed Claude running entirely inside their security boundary with AWS billing, but Bedrock access was gated and API-shape-divergent.
What: Opens Claude Opus 4.7 and Claude Haiku 4.5 self-serve to all Amazon Bedrock customers via the Messages API endpoint at /anthropic/v1/messages, across 27 AWS regions.
How: Call POST https://bedrock-mantle.{region}.api.aws/anthropic/v1/messages with model ID anthropic.claude-opus-4-7, or install pip install -U "anthropic[bedrock]".
Hosts: Alex Chen & Sarah Kim · Generated from the official Claude Platform release notes.
