Copilot is constantly summarizing conversation history and it takes 5+ mins every time. It is making copilot very slow/hard to use. This seems to have been getting worse and worse with time. #178513

I am experiencing the same problem recently - significantly - where i am working on a module (feature enhancement) in an existing project and conversation is very long because of planning, todos creation and research. Currently the situation is copilot is creating 2-3 files (roughly ~1500 lines of code) and then almost take 5 minutes for summarising the history. This is repeating with same frequency Overall execution time is getting too slow and painful model being used is Claude Sonnet 4.5 As the conversation is becoming longer, i can also notice the code quality is getting degraded and getting a lot of compilation errors and even syntax errors. |

same issue, at a point it takes so much time it becomes useless. |

It is painful to use, and I am not seeing how to not move to AntiGravity, Cursor, or OpenCode. |

Same issue here. And I remember better times, still. This started to get worse when "thinking" was introduced. |

Add my "me too" here. However I use VSCode and Copilot all day long at work and don't experience this. I am noticing it at home though on my personal account. I almost always use "Auto" or "Claude 4.5 Sonnet" (in both work/home). This was NOT an issue a week ago IIRC. I just started noticing it the past couple of days literally and I use this from everything from System Administration, to code, to home automations/dashboards, etc. I use it a LOT. I thought maybe it was some "experimental feature" I maybe enabled, but now I see others with my experience here... For example, this is after a Perplexity says, "it's not you, it's them" but IDK... this seems a pretty glaring problem and I'd think more people would be complaining loudly/louder. Are we part of a canary rollout maybe and that's why only some folks experience this terrible bug? I had it examine my |

As copilot just confirmed to me, this happens because the model you are using is running out of context capacity. What it probably does is writing a summary, then reseeding a new session with just the summary (rather than the full previous conversation). As @DAE51D suggested, you can see whether context isn't bloated for some silly reason (e.g. parsing of very large files). Note that best practices mention that any open files are typically added to the context, so you might e.g. want to close irrelevant files: https://docs.github.com/en/copilot/get-started/best-practices#guide-copilot-towards-helpful-outputs Alternatively, you can also switch to a model with a larger context size. You can check the model context size by clicking "Manage Models" in the model selection dropdown:

Copilot in vscode is starting to get to be impossible to use. It is constantly summarizing conversation history almost every other interaction and it is taking minutes to summarize the history. Often critical points get lost in the summarization and I have to remind the agent of details that it forgot in the summarization often triggering another conversation summarization. It is getting ridiculous and I am not getting this same nonsense in Cursor.
