Anthropic Announces Claude Opus 4.1
Anthropic has released Claude Opus 4.1, offering upgrades in agentic workflows, real-world coding, and reasoning at the same pricing as Opus 4.
ArticleAnthropicAnnouncement
For engineering teams and agentic workflows, Opus 4.7 improves reliability by cutting tool errors and maintaining coherence across extended runs. It also acts as the testing ground for Anthropic's new cybersecurity safeguards ahead of wider Mythos-class releases.
The update targets endurance, instruction adherence, and loop resistance in multi-step production environments. Partner benchmarks across Devin, Cursor, and Vercel show clear improvements in resolving complex bugs and parsing system requirements. Anthropic pairs these capability gains with strict cybersecurity guardrails stemming from Project Glasswing.
