I'm not 100x'ing my output like some people claim, but using it as a augmentation rather than delegating my work to it results in better code, and I don't lose context / control over my codebases. I really have read 100% of the code, because the LLM is generating smaller pieces around and inside my own written code. Works well enough for me, and open models are already both cheap enough and good enough for this workflow. This is why the big companies are so desperate to push full-on agentic hands-off workflows and developer replacement - that's the only way they won't go bankrupt.
I'm working on my own harness to be a bit more aligned with my workflow but tbh I'm losing motivation since other harnesses are fine now. I could probably vibe code something but there's not much point imo. Unless I come up with something completely different but who knows.
I think there is a Deepseek agent out there in Rust, but I've never tried it. Zed has been pretty decent with all models, not the best but certainly beats VSCode. ChatGPT 5.4 on that calls about 100 different git diffs to "verify" the changes are valid which is rubbish. I haven't tried Deepseek with it though.
Honestly these models and agents are becoming commodities, as long as they don't totally fail with tool calling or some stupid system instructions the models can figure stuff out pretty well.
