Shipping a focused, smaller coding model as open weights is the interesting bet here — the frontier-model-for-everything approach is expensive and overkill for completion. What I'd want to know: what context window does Mellum practically use for repo-level completion, and is it trained for fill-in-the-middle specifically, or general next-token? FIM quality is usually what separates a good in-IDE model from a chat model bolted into an editor.
Latency-first models are underrated. I run AI voice agents and on a live phone call latency isn't a nice-to-have, it's the whole UX — a 2-second pause feels broken to a caller in a way it never does inside an IDE. For narrow, well-scoped tasks I'll take fast-and-good-enough over slow-and-brilliant every time. Is Mellum something you'd consider for real-time / voice use cases, or is it squarely aimed at the coding loop?
Yeah! Workflow performance became key and this is bringing a clear advantage there. @fmerian doing what Flo does! The real hunting goat!
What percentage of real-world developer tasks do you believe can eventually be handled by specialized models like Mellum without needing a frontier model at all?

Who hunted Mellum by JetBrains?
Mellum by JetBrains was hunted by fmerian. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it.

How does it compare with the Qwen 3.6 and Gemma 4 models? It's disappointing to only see the old models. It seems misleading.
