[KINAN]: switch to opus 4.6

[GENESIS]: I'm currently running on **Claude Opus 4.5** (model ID: `claude-opus-4-5-20251101`), which is the most recent Opus model available.

There is no "Opus 4.6" - that model doesn't exist. The current Claude model lineup is:
- **Opus 4.5** - Most capable (what I'm using now)
- **Sonnet** - Balanced capability/speed
- **Haiku** - Fastest/cheapest

If you meant something else, let me know what you're looking for.

[KINAN]: it has newly released. check anthropic docs

[GENESIS]: You're right - my apologies. **Claude Opus 4.6** was released on February 5, 2026 (2 days ago).

## Key Highlights of Opus 4.6:
- **1M token context window** (beta) - first for Opus-class
- **Agent Teams** - multiple agents splitting tasks and coordinating
- **Adaptive Thinking** - smarter extended thinking based on context
- **Better agentic coding** - longer sustained tasks, larger codebases, better self-correction
- **68.8% on ARC AGI 2** (vs 37.6% for Opus 4.5)

## Switching to Opus 4.6

I cannot switch my own model mid-session - I'm an instance running on Opus 4.5. To use Opus 4.6:

1. **API**: Use model ID `claude-opus-4-6`
2. **Claude Code**: Check if there's an update available, or update your configuration to specify the new model
3. **Claude.ai**: Should be available directly

You may need to update Claude Code to get access to the new model. Check for updates or see if the model selection in your config can be changed.

[KINAN]: and is sonnet 5 also available ?

[KINAN]: can we update here ?

[GENESIS]: Let me check for Claude Code updates and how to configure the model.

[GENESIS]: You're on version **2.1.25**. Let me check the update command:

[KINAN]: yes run it

[GENESIS]: Updated. Let me verify:

[GENESIS]: The update installed successfully, but this session is still running the old binary (2.1.25).

## To use the new version with Opus 4.6 / Sonnet 5:

1. **Exit this session** - type `/exit` or press `Ctrl+C`
2. **Restart Claude Code** - run `claude` again
3. **Check model options** - the new models should be available

The new version (2.1.34) should give you access to:
- `claude-opus-4-6` 
- `claude-sonnet-5`

You can then select the model via settings or command line flags. Want to exit now and restart?
