A deep dive into how I trained an edit model to show highly relevant code suggestions while programming
This is def interesting for all SWEs who would like to know what goes behind the scenes in your code editor when you hit \`Tab\`. I'm working on an open-source coding agent and I would love to share my experience transparently and hear honest thoughts on it.
So for context, NES is designed to predict the next change your code needs, wherever it lives.
Honestly when I started building this, I realised this is much harder to achieve, since NES considers the entire file plus your recent edit history and predicts how your code is likely to evolve: where the next change should happen, and what that change should be.
Other editors have explored versions of next-edit prediction, but models have evolved a lot, and so has my understanding of how people actually write code.
One of the first pressing questions on my mind was: What kind of data actually teaches a model to make good edits?
It turned out that real developer intent is surprisingly hard to capture. As anyone who’s peeked at real commits knows, developer edits are messy. Pull requests bundle unrelated changes, commit histories jump around, and the sequences of edits often skip the small, incremental steps engineers actually take wh
Bluntly speaking, there’s a lot said here but not much clarified which turns this into more of a debate At least from my perspective.
From my side, this feels rushed rather than thought through which is why this is getting picked apart
Honestly, the main issue seems to be how this is handled which turns this into more of a debate
From where I sit, the timing matters more than people admit which explains why reactions are split Feels like there’s more coming here.
Real talk, this solves one problem while creating another which turns this into more of a debate
At first glance, the timing matters more than people admit and that’s why opinions are all over the place Interested to see the follow-up.
If you zoom out, this feels more about execution than intent so the response doesn’t surprise me That’s just how it reads to me.
From a neutral view, this feels like a half-step, not a full move and that’s where the disagreement starts That’s what changes the context. That’s just how it reads to me.
To be fair, this solves one problem while creating another That’s what changes the context. Others will probably see it differently.
Just reading this, the logic is there, but the execution is uneven and that’s the part people are stuck on That part stands out.
From where I sit, the follow-through is what will decide this which is why the comments look the way they do That’s what changes the context. We’ll see how people react over time.
On the surface, the idea isn’t bad, but the delivery is doing damage and that’s where the disagreement starts
If we’re being honest, the framing does a lot of heavy lifting here and that’s where people will push back At least from my perspective.
Stepping back, the way this is presented changes how it lands and that’s why opinions are all over the place
If we’re being honest, the framing does a lot of heavy lifting here Feels like an opening move, not an ending. Others will probably see it differently.
From a practical angle, the wording alone shifts how people read this and that’s why this won’t land the same for everyone That’s the key detail here. Feels like there’s more coming here. At least from my perspective.
the framing does a lot of heavy lifting here which makes the reaction pretty predictable That’s what changes the context. This probably isn’t the last word on it.
Looking at this, this depends heavily on what happens next and that’s why this won’t land the same for everyone Could be wrong, but that’s how it comes across.
From the outside, this comes across more reactive than planned That’s what makes this interesting. Hard to say where this lands long term. Others will probably see it differently.

If we’re being honest, the logic is there, but the execution is uneven This could age very differently in a week. That’s the impression it gives me.
