We're design the stack to be fairly flexible. It's Python/Pytorch under the hood, with the ability to plug and play various off the shelf models. For ASR we support GCP/AssemblyAI/etc, as well as a customized self-hosted version of Whisper that is tailored for stream processing. For the LLM we support fine-tuned GPT3 models, fine-tuned Google text-bison models, or locally hosted fine-tuned Llama models (and a lot of the project goes into how to do the fine-tuning to ensure accuracy and low latency). For the TTS we support Elevenlabs/GCP/etc, and they all tie into the latency reducing approaches.
