Together AI releases NVIDIA Nemotron 3 Ultra and 3.5 ASR models

By PulseAugur Editorial · [3 sources] ·

Together AI has released two new NVIDIA Nemotron models, Nemotron 3 Ultra and Nemotron 3.5 ASR. Nemotron 3 Ultra is designed for complex agentic tasks requiring long-term planning and iteration, boasting 550 billion parameters and a 1 million token context window. Nemotron 3.5 ASR is optimized for streaming speech recognition and voice agents, offering low-latency multilingual capabilities. AI

IMPACT Provides new open-source models for agentic workloads and speech recognition, potentially lowering barriers for developers.

RANK_REASON Release of new open-source models from a non-frontier lab.
