It actually looked at the skills, for the first time.

does anyone know how to use it in Claude Code cli right now ?

This doesnt work: `/model claude-sonnet-4-6-20260217`

edit: "/model claude-sonnet-4-6" works with Claude Code v2.1.44

Max user: Also can't see 4.6 and can't set it in claude code. I see it in the model selector in the browser.

Edit: I am now in - just needed to wait.

Seems like Claude Code v2.1.45 is out with Sonnet 4.6 as the new default in the /model list.

Honest question: why would anyone use Opus instead of this? I’m doing web development, the whole shebang, and I don’t think I need Opus right now. I know it’s supposed to be smarter, but a 2%–5% improvement doesn’t seem meaningful, especially when it costs more than double and has only a portion of the context window.

Am I getting this wrong? I would seriously appreciate any clarification here.

Why is the system "card" 140 pages long! Was it generated by LLM too?

Is someone able to use this in Claude Code?

You can use it by running this command in your session: `/model claude-sonnet-4-6`

so this is an economical version of opus 4.6 then? free + pro --> sonnet, max+ -> opus?

Opus is available in Pro subs as well and for the sort of things I do I rarely hit the quota.

How do people keep track of all these versions and releases of all these models and their pros/cons? Seems like a fulltime hobby to me. I'd rather just improve my own skills with all that time and energy

Unless you're interested in this type of stuff, I'm not sure you really need to. Claude, Google, and ChatGPT have been fairly aggressive at pushing you towards whatever their latest shiny is and retiring the old one.

Only time it matters if you're using some type of agnostic "router" service.

That's what I would recommend, it's time better spent. I use AI occasionally to bounce some questions around or have some math jargon explained in simpler terms (all of which I can verify with external sources) using the free version of chatgpt or gemini or whatever I'm feeling that day, without caring about whatever version the model is. I don't need an AI to write code for me because writing the code is not really the hard part of solving a problem, in my opinion.

For me it's simple. I did my research, settled on Anthropic and Claude and got the Pro plan at ~$20/month. That way I only have to keep track of what Anthropic are offering, and that isn't even necessary as the tools I use for AI-supported development (Claude Code for VS Code extension, Xcode Intelligence and Claude Desktop) offer me to use the newsest models as soon as they are released.

on a subscription you cant access all that many different options, so you just stay with whatever the newest is unless it doesnt work.
