- A hands-on test of Moonshot AI's Kimi K3.1 Pro via the Kimi Code harness: 2-3x faster than K3, completing a voxel-garden task in 5 minutes for $0.55, with the overthinking issue fixed.
- Benchmarked head-to-head against Opus 5.5, Astra, GPT-6.1 Sol, Sonnet 5.5 and DeepSeek V4.1-Flash on voxel pagoda scenes; screenshots show K3.1 Pro's design taste now approaching Astra-class closed models.
- Pricing: 5x cheaper than Astra, 3x cheaper than Opus 5.5, on par with GPT-6.1 Sol — open models are closing in on the frontier for 3D work.
