Claude Opus 4.6 context display shows 200k instead of 1M

[slotheather55]

Bug Description

The /context command displays claude-opus-4-6 · 103k/200k tokens (51%) — capping the context window at 200k tokens. However, Claude Opus 4.6 (released Feb 5, 2026) supports a 1M token context window.

Steps to Reproduce

1. Run Claude Code with model claude-opus-4-6
2. Run /context
3. Observe the displayed limit is 200k

Expected Behavior

Context display should show 103k/1,000k tokens (or similar), reflecting the 1M token context window for Opus 4.6.

Actual Behavior

claude-opus-4-6 · 103k/200k tokens (51%)

The 200k limit appears to be inherited from the previous Opus 4 model and was not updated for 4.6.

Environment

• Claude Code (latest as of Feb 8, 2026)
• Model: claude-opus-4-6
• Platform: Windows 11

You're supposed to enable it manually (the model). However, it's Beta and mostly enterprise users have it.

Many reviews suggest after 300k it just becomes unusable, very unstable. You're better off learning better context and memory management, agent orchestration, compaction techniques, etc... Rather than relying on larger context windows.
