Hey, a few others have mentioned similar things recently. There’s a related thread here: [Opus 4.6 was fun for 1 week..... why?!](https://forum.cursor.com/t/opus-4-6-was-fun-for-1-week-why/155751) One thing to keep in mind: Opus 4.6 in Max Mode uses extended thinking, which means the model does extra reasoning steps before producing the final output. This naturally increases response time compared to non-Max or non-thinking variants. That said, if it feels noticeably slower than before, we’d want to look into it. To dig deeper, I’ll need: 1. Request IDs from the slow sessions. Top right corner of the chat \> Copy Request ID. Even 2 to 3 examples would help. 2. How long are the responses taking roughly? Are we talking 30s, 1min+? 3. Are you seeing the same slowness with other models, for example Sonnet 4.6 or non-Max Opus? A couple of things to try in the meantime: - Start a fresh chat for new tasks instead of continuing long threads. Accumulated context can increase latency significantly. - Try Opus 4.6 without Max Mode to see if the speed difference is drastic. Share those request IDs and I can check what’s happening on our end. --- _[View the full topic](https://forum.cursor.com/t/has-anyone-noticed-performance-issues-with-opus-4-6-max-mode-recently/156370)._
