Moonshot’s 2.8T-parameter Kimi K3 escalates the open-weight AI price war

Chinese startup Moonshot AI released Kimi K3 on July 16, describing it as a 2.8-trillion-parameter open-weight multimodal model focused on coding, reasoning, and agentic work. API access is live, while downloadable weights are reportedly due July 27. Early coverage says K3 is competitive with leading US systems on selected benchmarks, but real-world reliability and the vendor’s benchmark claims remain insufficiently tested.
