<p>UPDATE:<p>After reading PUSH_AX's valid comment:
```
This is like saying contractor (A) asked for $33,000 to undertake the work and contractor (B) asked for $7,000
Are we measuring and caring about the right thing?
```
We will update the post to include:<p>1) A more in-depth task.
2) Qualitative results comparison.
3) As soon as possible, a reproduction of the inputs and outputs.</p>

<p>Model:<p>Cost, mainly. The runs went through a Claude Max subscription rather than metered API billing, and pinning an older stable snapshot kept run-to-run comparisons clean and cheap. The fixed harness payload (system prompt plus tool schemas), so the headline numbers shouldn't change too much.<p>That said, happy to re-run the matrix on Fable and publish the diff; payload figures should barely move, tool-calling behaviour might.<p>Gateway:<p>Meridian (github.com/rynfar/meridian); proxy that bridges the Claude Code SDK to a standard Anthropic endpoint so a Claude Max subscription can drive OpenCode-et-al.<p>It's the auth route for all agent traffic on the machine, not something built for the benchmark.</p>

<p>This started based off of a hunch. We usually use OpenCode, but were 'forced' to use Claude Code for a while due to issues with Meridian. In that time, we saw the usage meter rise much, much more quickly than when using OpenCode.<p>This was the initial anecdotal evidence, but we undertook this small study to collect empirical data:<p>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).<p>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.</p>

<p>Sorry, I missed part of your question:<p>What caused the switch was that we're building AI solutions for sometimes price-conscious customers, so I was already familiar with the pattern of "Use a superior model for setting a standard, then fine-tuning a cheaper one to do that same work".<p>So I brought that into my own workflows (kind of) by using Opus 4.6 to do detailed planning and one 'exemplar' execution (with 'over documentation' of the choices), then after that, use Opus 4.6 only for planning, then "throw a load of MiniMax M2.5s at the problem".<p>They tend to do 90% of the job well, then I sometimes do a final pass with Opus 4.6 again to mop up any issues, this saves me a lot of tokens/money.<p>This pattern wasn't possible with Claude Code, thus my move to Open Code.</p>
