picoLLM is an on-device inference SDK for developers building apps that run compressed language models on users' hardware. It generates text locally, so prompts don't need to go to a cloud inference service. Its main distinction is Picovoice's compression method, which learns how to allocate precision across model weights rather than applying a fixed allocation.

Spleeter is Deezer's music source separation library for developers and audio researchers who want to split recordings into separate vocal and instrumental tracks on their own hardware. It includes pretrained models, so you can separate audio without first training a model. The library is open source under the MIT license.
