Not sure if everyone noticed but Opus 4.6 now defaults to the full 1M context window in Claude Code. No extra cost, no config changes needed if you’re on Max/Team/Enterprise. Been using it on a large project and the difference is real, especially in long sessions where before it would start forgetting files I referenced 20 messages ago. Now it just keeps tracking everything. Model ID is claude-opus-4-6 btw. How’s it working for you guys? submitted by /u/NefariousnessHappy66
