Having tried local agents just two weeks ago, the parent poster is correct: they don't come anywhere near frontier models, despite what the benchmarks state. I haven't tried Qwen 3.6 yet, but the version before it frequently got stuck even on moderately complex problems.
Same experience for me. I think people need to start providing context for the type of work they're doing when repeating the local model hype. Maybe they're working with a cookie cutter React app and it does the job fine.
