I've been using Qwen 2.5 Coder
(bartowski/Qwen2.5.1-Coder-7B-Instruct-GGUF) for some time now, and it has
shown significant improvements compared to previous open weights models.
Notably, this is the first model that can be used with
Aider. Moreover, Qwen 2.5 Coder has made notable strides
in editing files without requiring frequent retries to generate in the proper format.
One area where most models struggle, including this one, is when the
prompt exceeds a certain length. In this case, it appears that the model
becomes unable to remember the system prompt when the prompt length is above ~2000 tokens.
It's a good model, way better than the models from half a year ago.
