Anthropic released Claude Opus 4.7 on April 16, 2026, positioning the model as a focused upgrade for advanced software engineering and long-horizon reasoning tasks. The new model shows concrete performance gains: on an internal 93-task coding benchmark, Opus 4.7 lifted resolution by 13% over Opus 4.6, including four tasks that neither Opus 4.6 nor Sonnet 4.6 could solve.
The improvement centers on execution rigor. Early testers report that Opus 4.7 handles complex, long-running tasks with consistency, catches its own logical faults during planning, and devises ways to verify outputs before reporting results. Clarence Huang, VP of Technology at Anthropic, noted the model "catches its own logical faults during the planning phase and accelerates execution, far beyond previous Claude models."
Beyond coding, Opus 4.7 gains substantially in vision. The model now processes images in greater resolution and shows improved multimodal understanding—users report benefits in areas like reading chemical structures and interpreting complex technical diagrams. Early testers in life sciences note the model is helping build "best-in-class tools for life sciences patent workflows, from drafting and prosecution to infringement detection and invalidity charting."
In other capability areas, Opus 4.7 shows improvements on internal benchmarks for research-agent work and financial reasoning. On one research-agent benchmark measuring multi-step task efficiency, Opus 4.7 tied for the top overall score across six modules at 0.715. On a General Finance module (the largest tested), it scored 0.813 versus Opus 4.6's 0.767.
Opus 4.7 is available across all Claude products, the Claude API, Amazon Bedrock, Google Cloud's Vertex AI, and Microsoft Foundry. Pricing remains unchanged from Opus 4.6: $5 per million input tokens and $25 per million output tokens.
One constraint: Anthropic deliberately reduced Opus 4.7's cybersecurity capabilities relative to Claude Mythos Preview. The company stated it would keep Mythos Preview's release limited and test new cyber safeguards on less capable models first. Opus 4.7 ships with safeguards that automatically detect and block requests indicating prohibited or high-risk cybersecurity uses. Security professionals conducting legitimate work—vulnerability research, penetration testing, red-teaming—can apply to Anthropic's new Cyber Verification Program for access. The company indicated that what it learns from real-world deployment of these safeguards will inform its eventual strategy for broader Mythos-class model release.
