Kimi K3 and Sol fail in different ways
The attached analysis breaks down failure modes on the same benchmark:
- Kimi K3 gets closer to the target but more often stops short of passing every test.
- GPT-5.6 Sol breaks more baseline tests.
The chart quantifies the difference:
- Kimi K3: 65% near misses, 11% partial, 13% big misses, 11% broke baseline
- Sol: 54% near misses, 15% partial, 11% big misses, 20% broke baseline
The author notes Sol’s 20% baseline-breaking failures are consistent with other GPT models, while Kimi’s profile looks more like Claude-style regressions.
