Augment does not have a model picker. It uses Claude 3.7 right now. The context engine is the magic sauce. Itβs miles ahead of all the other tools, almost always gets it right where others fail.
I haven't fully stress tested it, but from brief use their proprietary context engine just feels like a gimmick to draw in VC investments. You can't convince me you get better end performance using an older model. Especially as most AI coding tools draw closer to enshitification with opaque context compression to save on costs
YMMV, but I've found it really does work and isn't a gimmick. It gets problems right that Cursor, Roo, Windsurf, etc trip up on because somehow it finds exactly the relevant stuff for context at a granularity you can't really achieve by @mentioning whole files/directories in other tools. I'm going to enjoy it at least until something better comes along. I think the "relevant accurate context is better than just adding more context" approach is the way to go.
I find the autocomplete model a lot better than cursor/copilot as well. IMO it does a much better job of understanding the intention of your changes and generating relevant changes across files. I think that's also due to the context engine, it checks for relevant changes to the task at hand across files rather than being mostly "local".
