pipecat-ai/phonellm-alpha-1
PhoneLLM Alpha 1 is an open-weights language model from the Pipecat team designed for voice agent use cases, such as handling inbound customer service calls and outbound calling tasks when paired with transcription and text-to-speech models. It is a full-parameter fine-tune of NVIDIA's Nemotron 3 Nano 30B-A3B, a mixture-of-experts model with 3.5B active parameters, and is trained to invoke tools accurately in multi-turn conversations without requiring thinking tokens. It is released under the BSD license with no commercial restrictions and can be run on your own infrastructure.
