New Kimi K2.7 Code performs at GPT-5.5 level 3x cheaper!
We gave both models the same three prompts: build a self-contained HTML5 canvas sim with real physics, no libraries. A spring pendulum on a stretching coil, a 1 kg block trading collisions with a 100,000 kg block, and 22 balls churning in a spinning hexagon
Outputs:
Kimi K2.7 Code: $0.28 on 52.4k tokens
GPT-5.5: $0.93 on 23.4k tokens
Spring pendulums and blocks came out even. The balls Kimi did better: its pile spins with the drum when GPT's bounce around in pure chaos. On price to quality, K2.7 Code is the clear pick
