"The AI labs never sleep - especially the week before Thanksgiving, it seems. Days after Google's buzzworthy Gemini 3, and OpenAI's updated agentic coding model, Anthropic has announced Claude Opus 4.5, which it bills as "the best model in the world for coding, agents, and computer use," claiming it has leapfrogged even Gemini 3 in different categories of coding. But the model is still too new to have made waves on LMArena yet, a popular crowdsourced AI model evaluation platform."
"The company's blog post also says Opus 4.5 is significantly better than its predecessor at deep research, working with slides, and filling out spreadsheets. Additionally, Anthropic is also releasing new tools within Claude Code, its coding tool, and its consumer-facing Claude apps, which it says will help with "longer-running agents and new ways to use Claude in Excel, Chrome, and on desktop." Claude Opus 4.5 is available today via Anthropic's apps, API, and all three major cloud providers, per Anthropic."
Claude Opus 4.5 is a newly released model positioned for coding, agents, and general computer use, claiming improvements over rival models in multiple coding categories. The release follows recent updates from other labs and is currently too new to have extensive third-party benchmark coverage on platforms like LMArena. The model reportedly improves deep research, slide handling, and spreadsheet work. Anthropic is also introducing new tools in Claude Code and consumer Claude apps to support longer-running agents and integrations with Excel, Chrome, and desktop environments. Availability includes Anthropic apps, the API, and major cloud providers, while agent security remains a noted concern.
