This was the initial anecdotal evidence, but we undertook this small study to collect empirical data:
We added logging between the agentic coding tool (Claude Code and OpenCode) and Anthropic's endpoint, and captured all requests (and the returned usage blocks).
With one caveat (toward the end of the post) we found unambiguously that Claude Code was far more inefficient in terms of its cache strategy and its harness token usage than OpenCode.
Suspect that many have covered the "Comparing agentic coding tools" angle before, and that the differentiator is depth of analysis + conclusions.
Claude is much better in OpenCode then in Claude Code, OpenCode is just better than Claude Code. Claude Code feels like a complete mess to use comparatively.
I'm quite impressed with Grok 4.5 because its speed and single-task effectiveness feels better than anything else for a human-in-the-loop workflow. (For the stuff I do, I'm not interested in having AI race ahead of what I can oversee.)
All models do things in a way I personally disagree with at least some of the time. The "dumber" models sometimes fail to recognise how to fit a solution into existing code. The "smarter" models sometimes get too clever and over-engineer their solutions. Cleverness is occasionally interesting, but is just as likely to trigger a distracting rabbit hole where I spend time analysing whether something unexpected was a legit insight, or mere opinion.
