A second-rack bagel that's nearly first-rack. Tasty stuff.
Summary
MiniCPM 4.0 is a family of ultra-efficient, open-source AI models designed for on-device deployment, offering significant speed improvements on edge chips. The launch includes VoxCPM2, a 2B parameter open-source text-to-speech model with 48kHz output, 30-language support, voice design from text, controllable voice cloning, and real-time streaming capabilities suitable for production workflows. The models are highly quantized with BitCPM versions for efficient edge deployment.
