ArtificialAnalysis puts out benchmarks for harnesses now as well, and OpenCode seems to be winning it. https://artificialanalysis.ai/agents/coding-agents#coding-agents-harness-comparison-chart-tabs https://artificialanalysis.ai/agents/coding-agents#coding-ag... I only found this yesterday, and it inspired me to start testing out OpenCode.

I'm not surprised to also see Cursor above Claude code, their harness is very good.

  In what scenarios?

    It indexes the code efficiently, seems to find stuff quicker, it has a very nice UI (much better than Claude Codes IMO), it has a nice sub-agent UX which I find triggers more reliably, diffs render nicely. Otherwise it just seems to work in a purely vibes sense. That said Claude Code is perfectly fine. I just prefer the integrated experience of using Cursors since I already use VSCode, but I still mostly use Claude Code because of their Max/Fable plan.

Can OpenCode dispatch background subagents yet? I tried it a week ago and saw nothing. This is 99% of my workflow at this point.

  Having just "asked" my opencode instance-- Yes, but it's behind an experimental flag and not necessarily feature-complete.
- jauntywundrkind 1mo ago
  In the new v2 beta, yes. Major QoL upgrade, so much less sitting around waiting.

    The v2 branch of OpenCode has not been touched for months, if it's beeing developed then I don't know where.
    - jauntywundrkind 1mo ago
      this is very easy to check. i promise i'm not tricking you and just uploaded this. https://github.com/anomalyco/opencode/tree/v2 https://github.com/anomalyco/opencode/tree/v2 this is the integration branch for https://opencode.ai/v2 https://opencode.ai/v2 . it has been for months. it's where the Effect-based refactor has been landing.

        sorry, I was mistaken! I looked at https://github.com/anomalyco/opencode/tree/2.0 https://github.com/anomalyco/opencode/tree/2.0

Just a warning, this is on Opus. There's not a clear harness winner. It will change depending on the models.
