What changed
Anthropic launched Opus 4.7 with stronger advanced software engineering performance, self-verification behavior, better vision, and selective cybersecurity safeguards.
Why it matters
Frontier model competition is moving toward reliability and multi-step autonomy, not just broader benchmark coverage.
Evidence
Anthropic says Opus 4.7 improves advanced software engineering, devises ways to verify its own outputs, and is available across Claude, API, Amazon Bedrock, Google Cloud Vertex AI, and Microsoft Foundry.
