Kimi K3 reasoning trace shows both correct math and a clear error
teortaxesTex · x · 2026-07-20
Teortaxes says the Kimi team should treat this kind of case as a goldmine for GRM training: Sol/Fable inspect K3’s reasoning chain and find both strengths and mistakes.
From the screenshot’s analysis:
- K3 is said to reason through the core math correctly and reach the right conclusion.
- It also makes a conspicuous elementary error and adds unsupported speculation.
- The author notes it checks point evaluations, Jacobians, and symbolic determinants, ultimately concluding the map’s determinant is identically -2.
- The screenshot also flags a separate issue: the model misstates the degree of the map and overclaims a “Pinchuk-style suspension.”
The overall takeaway is that K3 can sustain valid symbolic reasoning over a long chain, but still carries a shallow local unreliability that shows up in details.
