What is NVIDIA NeMo?

NeMo split itself apart: the flagship repo is now a speech toolkit and nothing else.

NeMo has spent the last six months on a controlled demolition. The 2.7.0 notes warned that avlm, diffusion, llm, multimodal, nlp, speechlm, vision and vlm collections would be removed; NeMo Speech 3.0 executed it, splitting the repository, renaming it to NVIDIA-NeMo/Speech and moving everything non-speech to sibling repos. The release removed 800k lines of deprecated code, moved to uv for installs, cut dependencies and shipped lighter containers. Patch releases in between were security fixes and CUDA binding repairs.

What is Ollama?

Ollama v0.40.11 adds local speech output on macOS, with an OpenAI-compatible audio endpoint.

Ollama v0.40.11 can generate speech on macOS: ollama run reads text or a model's reply aloud as it is produced, and apps can stream audio from an OpenAI-compatible /v1/audio/speech endpoint using the Phonon voice model. The same release adds d3, a family of 2B–27B decision models that classify, answer yes or no, or score options with probabilities. v0.40.10 added NVIDIA's Nemotron 3.5 Bolt E4B with a speculative-decoding draft.

NeMo split itself apart: the flagship repo is now a speech toolkit and nothing else.

◆ Current state

NeMo has spent the last six months on a controlled demolition. The 2.7.0 notes warned that avlm, diffusion, llm, multimodal, nlp, speechlm, vision and vlm collections would be removed; NeMo Speech 3.0 executed it, splitting the repository, renaming it to NVIDIA-NeMo/Speech and moving everything non-speech to sibling repos. The release removed 800k lines of deprecated code, moved to uv for installs, cut dependencies and shipped lighter containers. Patch releases in between were security fixes and CUDA binding repairs.

◆ Where it's heading

This is a scope decision, not a cleanup. NeMo is trading its position as a general-purpose model framework for a defensible one as the speech toolkit — ASR, TTS, speaker tasks and SpeechLM — and accepting a hard migration for everyone else. The feature work that did ship in 2.7.0 points the same way: streaming speech translation, per-stream phrase boosting, and new streaming ASR and multilingual TTS models.

◆ Prediction

With the split done, expect the next releases to be speech-model drops rather than framework changes, and the separated repos to start versioning independently.

6.3

Ollama v0.40.11 adds local speech output on macOS, with an OpenAI-compatible audio endpoint.

◆ Current state

Ollama v0.40.11 can generate speech on macOS: ollama run reads text or a model's reply aloud as it is produced, and apps can stream audio from an OpenAI-compatible /v1/audio/speech endpoint using the Phonon voice model. The same release adds d3, a family of 2B–27B decision models that classify, answer yes or no, or score options with probabilities. v0.40.10 added NVIDIA's Nemotron 3.5 Bolt E4B with a speculative-decoding draft.

◆ Where it's heading

Ollama is widening from a local text LLM runner into a local runtime for several model types: vision, decision scoring and now speech. The release candidates show the groundwork, with Phonon checkpoint support, a voice catalog and Gemma 4 draft heads landing over a few days before the stable cut.

◆ Prediction

Expect speech output to reach Linux and Windows and more voices in the Phonon catalog; the decision-model work (PPLX Decider, d3) suggests more classifier-style models.
