16201620* **Clear between tasks**: run `/clear` when switching to unrelated work. Old conversation crowds out the files you need next and costs tokens on every message.
16211621* **Delegate large reads**: send research to a [subagent](/docs/en/sub-agents) so the file contents stay in its context window, not yours.

1623If you need a larger window rather than a smaller conversation, Fable 5.1, Fable 5, Sonnet 5, Opus 4.6 and later, and Sonnet 4.6 support a 1 million token context window. See [Extended context](/docs/en/model-config#extended-context) for availability by plan and how to select a `[1m]` model variant. Sonnet 5 runs at 1M with no `[1m]` variant to select; see [Sonnet 5 context window](/docs/en/model-config#sonnet-5-context-window) for its auto-compaction thresholds and the LLM gateway exception. Compaction works the same way at the larger limit.

1625Sonnet 5 runs with the 1M context window and has no `[1m]` variant to select. See [Sonnet 5 context window](/docs/en/model-config#sonnet-5-context-window) for its auto-compaction thresholds and the LLM gateway exception.

16251627The point where automatic compaction runs depends on your model and configuration. See [Default auto-compact thresholds](/docs/en/model-config#default-auto-compact-thresholds) for the boundaries per model, and [Correct the window for a gateway or custom model ID](/docs/en/model-config#correct-the-window-for-a-gateway-or-custom-model-id) if Claude Code assumes the wrong window for your model ID, such as an [LLM gateway](/docs/en/llm-gateway) alias.
