1-bit Kimi K3 Quant Tested: 2.8T Model Compressed to 590GB Runs Locally
rohanpaul_ai · x · 2026-08-01
A developer conducted local deployment tests on the 1-bit quantized version of Kimi K3. This quantization successfully compressed the 2.8 trillion parameter model to 590GB (a 62% reduction) while fully retaining the 1M context capability.
In an HTML 3D physics engine test, the local 1-bit K3 running on 4x B200 GPUs performed excellently. It not only handled physics collisions correctly but was also the only model to successfully build a working winch, matching the performance of cloud-based models like Opus 5.
