``` Claude Code v2.0.13 Sonnet 4.5 (with 1M token context) Claude Max /Users/jesse/tmp/new-tool/.worktrees/todo-cli ```

How does this person have access to Sonnet 4.5 with 1m token context? I don't see this referenced anywhere when I search or when I ask Claude about it.

It’s a limited release beta feature not available to all. You can try to activate it by doing: /model sonnet[1m] And it accepts it but the at the next API call it may fail and say “this beta model is not available with your subscription”.

I haven’t gotten access yet.

One of the nice things about Codex (GPT-5) is the supposed 400k token context (although performance starts to deteriorate when you get to 80% context usage).

OpenRouter shows Sonnet 4.5 as having a 1M context limit: https://openrouter.ai/anthropic/claude-sonnet-4.5
