Sonnet 1m - what is the magic config to enable this?

[whizzzkid]

I am sure I was seeing the option to select the Sonnet 1M earlier, but with last update this is missing. here's my agent-servers setting:

    "claude-acp": {
      "default_config_options": {
        "effort": "max",
        "model": "claude-sonnet-4-6[1m]",
      },
      "favorite_config_option_values": {
        "effort": ["max"],
        "mode": ["auto"],
      },
      "type": "registry",
    },

But I only see:

This results in frequent compaction and disrupts my workflow. Also, where are all the config options documented? I've been looking for those but could not find it.

Hmmm we get this list from anthropic, we aren't adapting it.
If you set sonnet[1m] in your ~/.claude/settings.json though it should show up: https://code.claude.com/docs/en/model-config

@benbrandt I have that setup, claude in terminal always uses the 1m context, the ACP however falls back to 200k
