Inflect v2 ships two complete TTS models at 3.97M and 9.36M parameters.

owensong released Inflect-Nano-v2 (3,966,721 deployable params) and Inflect-Micro-v2 (9,356,513) under Apache-2.0, VITS-family end-to-end text-to-waveform with 128 latent channels, 3 encoder layers, 4 flow coupling blocks, 24 kHz mono. Nano-v2 runs at 0.0933 RTF (10.72x real-time) on four CPU threads; Micro-v2 at 0.1593 RTF (6.28x). The trade-off is deliberate: English only, one fixed male voice, and the training-corpus pipeline stays private, so it's open-weight not open-source. 410 upvotes on r/LocalLLaMA. Usable on-device TTS now fits in under 10MB of parameters, which puts voice output inside embedded budgets that ruled it out a year ago.
