Qwen2.5 Omni: See, Hear, Talk, Write, Do It All! I'm not sure how I missed this one at the time, but last month (March 27th) Qwen released their first multi-modal model that can handle audio and video in addition to text and images - and that has audio output as a core model feature.

We propose Thinker-Talker architecture, an end-to-end multimodal model designed to perceive diverse modalities, including text, images, audio, and video, while simultaneously generating text and natural speech responses in a streaming manner. We propose a novel position embedding, named TMRoPE (Time-aligned Multimodal RoPE), to synchronize the timestamps of video inputs with audio.

Here's the Qwen2.5-Omni Technical Report PDF.

As far as I can tell nobody has an easy path to getting it working on a Mac yet (the closest report I saw was this comment on Hugging Face).

This release is notable because, while there's a pretty solid collection of open weight vision LLMs now, multi-modal models that go beyond that are still very rare. Like most of Qwen's recent models, Qwen2.5 Omni is released under an Apache 2.0 license.

Qwen 3 is expected to release within the next 24 hours or so. @jianxliao captured a screenshot of their Hugging Face collection which they accidentally revealed before withdrawing it again which suggests the new model will be available in 0.6B / 1.7B / 4B / 8B / 30B sizes. I'm particularly excited to try the 30B one - 22-30B has established itself as my favorite size range for running models on my 64GB M2 as it often delivers exceptional results while still leaving me enough memory to run other applications at the same time.
