Kimi K3.1 Pro beats rivals on benchmarks but struggles on robotics and hard tasks
Afinetheorem · x · 2026-10-24
- Researcher Afinetheorem weighs in on Kimi K3.1 Pro: a competent team and a nice model, but like recent models with heavy RL post-training, general performance and "emergent capabilities" fall short.
- Cited testing shows K3.1 Pro performs poorly on robotics tasks despite beating Astra and Argon on popular benchmarks like Terminal-Bench.
- His take: the AA Index is only a proxy — on genuinely hard tasks, K3.1 Pro is clearly not at the level of Astra or Gemini 5.5, suggesting benchmark scores don't reflect real capability.
