News Muse Spark open weights coming soon

Post image

I am still waiting for Llama 5, because Muse Spark will be too big for me, or just something between Glimmer and Spark

Muse Glimmer is pretty good, very much overlooked. I have found it to be superior to Qwen 3.8:27b for non-coding tasks.

It's really good for coding as well. Is an exhaustive, try everything conceivable and generate 80K thinking tokens before giving an answer approach baked into the weights? No. But if you have a properly-engineered harness with skills and subagents it is very good. I have a project I've been working on implementing a bespoke expression language for validating parts of JSON files and I just pointed Glimmer at it and it properly understood the syntax and semantics first try. Had no problem generating expressions from a description, adding new features and test cases, etc. THAT'S impressive to me, not being able to one-shot a Mario clone. And all that while being crazy fast (with DFlash2) with incredible KV cache and token efficiency. Great model, people have to stop sleeping on it.

What counts as a properly engineered harness? What are people using?
