Recently, large language model releases have been coming one after another, like dumplings being dropped into boiling water.
Gemini 3 Pro stole the spotlight for just two weeks before Claude Opus 4.5 was officially launched, still focusing on programming with that familiar flavor.
Anthropic officially claims that Opus 4.5 is overall smarter and more hassle-free. When it comes to “system-level tasks” like programming, building agents, and computer control, it remains among the world’s best. Daily desk work, such as research, making presentations, and processing spreadsheets, has also noticeably improved.
Starting today, Opus 4.5 is fully available and can be accessed through applications, API, and three major cloud platforms. Developers just need to call claude-opus-4-5-20251101 in the Claude API.
Along with the release comes a complete toolchain upgrade. The developer platform, Claude Code, Chrome extension, Excel integration, desktop application overhaul, and “uninterrupted long conversations” have all been updated. From applications to APIs to cloud platforms, this rollout truly covers all fronts.
