Claude Opus 5

Claude Opus 5 is Anthropic’s Opus-tier model for coding, long-running agents, research, and professional knowledge work across Claude plans.

Claude Opus 5

Overview

Claude Opus 5 is Anthropic’s latest Opus-tier model, announced as available in July 2026. The page describes it as a thoughtful and proactive model designed for everyday use, long-running agents, coding, and other professional knowledge-work tasks.

Anthropic positions Opus 5 as more efficient than earlier models at the same cost as Opus 4.8, with results that improve across effort settings. The announcement also says it is the new default model on Claude Max and the strongest model on Claude Pro, while the pricing page places Opus within Claude’s broader Free, Pro, Max, Team, Enterprise, and API plan structure.

Features

Coding and professional-work performance

The announcement positions Opus 5 as a strong model for coding and professional work, with state-of-the-art results on Frontier-Bench v0.1 and strong results on CursorBench 3.2 and AA Coding Agent Index-related evaluations.

Effort settings for speed and cost control

Anthropic says customers can use effort settings to optimize for intelligence or conserve tokens for faster and cheaper results, and that Opus 5 is more efficient than other models at everyday use.

Careful agent behavior

The model is described as much stronger at verifying its work and iterating carefully until it succeeds, with examples focused on debugging, root-cause analysis, and multi-step completion.

Broader knowledge-work strength

The page highlights gains on knowledge-work and problem-solving benchmarks such as ARC-AGI 3, Zapier AutomationBench, OSWorld 2.0, GDPval-AA v2, HLE, AutomationBench, and DeepSearchQA.

Research-oriented performance

Anthropic says Opus 5 improves on life-science evaluations covering structural biology, organic chemistry, and bioinformatics, including specific gains on molecular-structure inference and protein-related tasks.

Visual output generation

The announcement says Opus 5 can produce stronger visual outputs, including an aerodynamic flow visualization and a simplified interactive cell illustration.

Use cases

  • Software engineering and debugging

    Use Opus 5 for coding tasks where the model needs to debug, reconstruct behavior, or carry a project through to a working result. The announcement’s examples include root-cause analysis, a FreeCAD reconstruction task, and difficult software fixes.

  • Long-running agents and automation

    Use it for multi-step knowledge work that benefits from checking assumptions and staying on task through long runs. Anthropic highlights business-task automation, analytical work, and other professional workflows where careful iteration matters.

  • Scientific research

    Use it for research-oriented work in areas such as structural biology, organic chemistry, bioinformatics, and related life-science analysis. The page specifically calls out stronger performance on molecular-structure inference and protein-related tasks.

  • Computer-use workflows

    Use it when a task needs computer-use or browser-like interaction rather than only text generation. The source points to OSWorld 2.0 and other computer-use benchmarks, plus examples of end-to-end business tasks.

  • Visual and explanatory outputs

    Use it for visual explanation tasks that involve producing or improving diagrams and interactive illustrations. Anthropic cites stronger generated visuals, including a wind-tunnel visualization and a simplified cell illustration.

Pros and Cons

Pros

  • Strong results on coding and software-engineering evaluations, including Frontier-Bench v0.1 and CursorBench 3.2.
  • Designed to work efficiently, with effort settings that let users trade off quality, speed, and token use.
  • Shows improved performance on knowledge work, problem solving, automation, and computer-use benchmarks.
  • Anthropic highlights stronger research performance across life sciences tasks.
  • The model is described as more thorough at verifying work and iterating until a task is complete.

Cons

  • The announcement says Opus 5 remains behind Mythos 5 on cybersecurity tasks.
  • The source does not provide a full public feature list for connectors, APIs, or workspace integrations specific to Opus 5.
  • Several claims rely on benchmark and early-access evaluation results rather than a complete product specification.
