Anthropic rolls out Claude Opus 4.6 for long-context workloads
Summary
Anthropic has released Claude Opus 4.6, an updated Opus-class model designed for coding workflows and long-context use, featuring a 1M token context window in beta. This marks the first Opus-class model from the San Francisco-based AI company to support such an extensive context. Claude Opus 4.6 is available via claude.ai, its API, and major cloud platforms, with standard pricing at $5/$25 per million tokens, and premium pricing of $10/$37.50 for prompts exceeding 200,000 tokens. The model demonstrates improved coding capabilities, more reliable operation in large codebases, and stronger debugging. It also excels in financial analysis, research, and document creation, outperforming OpenAI's GPT-5.2 on GDPval-AA by 144 Elo points and leading on Terminal-Bench 2.0 and Humanity's Last Exam. The release includes product updates like adaptive thinking, effort controls, context compaction, and integrations with Excel and a research preview for PowerPoint.
Key takeaway
For CTOs and VPs of Engineering evaluating large language models for complex enterprise applications, Claude Opus 4.6's 1M token context and enhanced agentic coding capabilities present a compelling option. Your teams can leverage its improved performance in financial analysis, research, and document creation, potentially streamlining workflows and reducing development cycles for long-horizon tasks.
