That had me bogling too. But you know what? A local MoE model roughly equivalent to sonnet mid-2025? Totally possible. Just costs electricity to run, put it in your CI/CD pipeline. Have it apply a bit of intelligence to the thing as well. Uh.... if you've got a spare box, why not?
(the fact that said spare box would cost an arm and a leg in 2026 is... a minor detail)
Why not? Because you can get stronger guarantees of correctness and consistency out of a typical code formatter, which will also probably run about a million times faster.
