Kimi K3 model too large for local use, surpassed by newer models

Three months after its release, the Kimi K3 model is proving too large for most users to run locally, with its smallest recommended quantization requiring nearly 600 GB of RAM and VRAM. While initially hyped as a top-tier open model, its performance has been surpassed by newer models like GLM-5.3 and Step 5 Preview, which now score higher on benchmarks. Furthermore, Kimi K3's license restricts commercial use for companies exceeding $20 million in annual revenue without a separate agreement with Moonshot. AI
