On February 5, 2026, Anthropic released Claude Opus 4.6 — their most capable model to date. Opus 4.6 delivers significant improvements across coding, agentic workflows, knowledge work, and long-context reasoning. It achieves state-of-the-art results on multiple industry benchmarks and introduces a 1M token context window (in beta) — a first for Opus-class models.
AI·Collab now supports Claude Opus 4.6, giving you access to this frontier model alongside 300+ other AI models in one unified, GDPR-compliant workspace. Whether you're building agentic workflows, tackling complex codebases, or running sophisticated research tasks, Opus 4.6 is ready when you need it.
Opus 4.6 brings substantial upgrades across the board. Here's what makes it stand out:
Better planning, longer-running agentic tasks, reliable operation in large codebases. Improved code review and debugging — the model catches its own mistakes more effectively.
Context compaction for longer-running tasks, adaptive thinking that adjusts effort based on context, and new effort controls for developers to balance intelligence, speed, and cost.
Financial analysis, research, document creation, spreadsheets, and presentations. Integrates with Claude in Excel and Claude in PowerPoint (research preview) for everyday work.
Opus 4.6 is the first Opus-class model with a 1M token context window. Handle vast documents and long-running conversations without losing coherence.
Opus 4.6 achieves state-of-the-art results across multiple evaluations. Here are the highlights:
Highest score on the agentic coding evaluation. Opus 4.6 excels at multi-step coding tasks that require planning, tool use, and sustained execution.
Leads all frontier models on this complex multidisciplinary reasoning test. Opus 4.6 demonstrates exceptional reasoning across diverse domains.
Outperforms GPT-5.2 by ~144 Elo points and Opus 4.5 by 190 points on economically valuable knowledge work in finance, legal, and other professional domains.
Best-performing model at locating hard-to-find information online. Ideal for research tasks that require web search and synthesis.

Opus 4.6 maintains an overall safety profile as good as or better than any other frontier model. Low rates of misaligned behavior across safety evaluations, and the lowest rate of over-refusals of any recent Claude model — meaning it answers benign queries more reliably while still refusing harmful requests.
Getting started with Claude Opus 4.6 on AI·Collab is straightforward:
In your AI·Collab chat interface, click the model selector dropdown. Search for "Opus 4.6" or "claude-opus-4-6".
Choose Claude Opus 4.6 from the list. If you don't see it, ensure your organization has enabled Anthropic models in settings.
Begin your conversation. Opus 4.6 excels at complex reasoning, coding, research, and multi-step tasks. Pair it with Skills, Knowledge Base, or Web Search for maximum impact.
Pricing follows AI·Collab's credit system. Opus 4.6 is a premium model — check the Models page and your account settings for current credit rates. Anthropic's list price is $5/$25 per million tokens (input/output).
The 1M token context is in beta on Anthropic's Developer Platform. AI·Collab provides access through OpenRouter and other providers — check the model card for the context window available in your setup.
Use Opus 4.6 for the most demanding tasks: complex coding, agentic workflows, long-context analysis, and knowledge work where accuracy matters. For simpler tasks, Sonnet or Haiku may be faster and more cost-effective.
AI·Collab applies GDPR-compliant data handling (PII redaction, privacy guardrails). Opus 4.6 is not currently served via EU model origin — inference runs in the provider's default region. For models with EU routing, see our EU routing blog post.
