Enabling /extra-usage in my (personal) claude code[0] with this env:

    "ANTHROPIC_DEFAULT_SONNET_MODEL": "claude-sonnet-4-6[1m]"

has enabled the 1M context window.

Fixed a UI issue I had yesterday in a web app very effectively using claude in chrome. Definitely not the fastest model - but the breathing space of 1M context is great for browser use.

[0] Anthropic have given away a bunch of API credits to cc subscribers - you can claim them in your settings dashboard to use for this.

That sounds awesome but I’m pretty sure you get charged for it in addition to a max plan you may already be paying 100 or 200/month for. Otherwise, I’d be all over opus 4.6 1m. Could be worth the cost of course but I’m not in a position to spend that right now.

/extra-usage inside claude code also works
