We put Claude Opus 4.6 to the test against Opus 4.5 using the Cosmic AI Platform. Same prompt. Same setup. Two very different results. The prompt: "Create a blog with posts, authors, and categories." Here is what we found... 🧵

Opus 4.5 delivered a clean, well-organized blog with solid architecture and good fundamentals. Opus 4.6 took it further: cohesive brand identity, editorial-grade design, featured articles with rich imagery, and stronger creative decisions with zero extra prompting.

The benchmarks back it up. Opus 4.6 leads in agentic coding, search, reasoning, finance, and office tasks. Plus it now supports 1M token context, 128k output tokens, adaptive thinking, and agent teams. Same price as Opus 4.5. Significant capability upgrade.
