Anthropic released a new model, Opus 4.5 and i'm playing with it. I had it generate some docs for a server i'm working on setting up, and it created a docx file which was nicely formatted instead of a markdown file.

docx is a zip-based format. It must have used a tool to do that
Yeah those tools are fairly recently introduced, it’s probably instructed to use them. I think I’d prefer the markdown haha
Wonder if opus is just Claude Sonnet with Claude Skills added
I think we are saturated somehow in LLM knowledge. So now they only can increase profit by adding tools.
It can actually spin up a Linux container (for just that session) that contains Python modules for various office files. Pretty cool.
From the presentation:
> Advanced tool use (beta): Build agents that can take action with three new capabilities—the tool search tool, programmatic tool calling, and tool use examples. Together, these updates enable Claude to navigate large tool libraries, chain operations efficiently, and accurately execute complex tasks.
that’s kinda cool
Have you got Claude Code to not run out of context? Still seems to for me - and doesn’t default to Opus 4.5 (others said it did).
