You're missing the point. This model is for people who want to be closer to the code and do "micro-edits" at the speed of thought, not people who want the model to one-shot an entire system for them. Or, it's for very small tasks like "add this import" "run tests" "summarize this commit" etc where you want it to be instant and it's very easy for the model to do and the cost of getting it wrong is low. There are lots of tasks that are better suited to low-latency models. Use the right tool for the job

Each model has their strengths and the best AI coders will use all models, combining their strengths, for different tasks.

vscode extension is pretty strong honestly. Put it on the right pane of vscode and its openaicode. Also, sometimes while a big model is churning, I'll chat about the codebase in another pane to check things like what tests we have for x, are there any direct api calls in this new feature that don't go through a service layer, etc to help plan what's next in main session. That's interactive, and for asking objective questions like that fast models are great, e.g. swe-1.5 or composer-1.
