Mei was updated to 0.6.1, for the Ornith 1.5 model weighted avg TPS improved slightly, same for TTFT, and total task time was better. Qwen 3.6 only improved on task time and TTFT. Progress has slowed a bit, definitely harder to get gains now without making another metric worse. github.com/tijs/mei

I want to reverse this whole agent thing. Why do I need to keep telling it what to do if instead it can just ask me if it needs anything and just fuck off and do its own thing the rest of the time.

Starting today in version 2.1.277, if there is
no CLAUDE.md in a folder, Claude will
check for and use AGENTS.md.
You can toggle this behavior in /config.

New inference demand just dropped! This feature prefers Qwen2.5-7B-Instruct-4bit / gemma-4-12b / gemma-3-4b-it-qat-4bit in that order so start hosting those and make sure you're updated to the latest version!

@cocore.dev this also means cocore on mlx is likely viable again 😛 I think most of these optimizations would translate fine, though Mei is single user and I guess cocore is not so that might need some tinkering still.

With the release of Mei 0.5.0 it has become much easier to run things. You can brew install and all the important settings have good defaults now. Also; Ornith 1.5 is no longer the front runner, my text only version of Qwen 3.6 27B beats it in my benchmarks. github.com/tijs/mei

We already peaked, for agentic software engineering, with Opus 4.8 (5 acts like a confused older gentleman most of the time) and Sol 5.6. Or actually with Sonnet and Terra (or Luna at max effort which is my fav now).

I'm basically left with Ornith 1.5 and Qwen 3.6 as viable models for this machine. Since Ornith is text only i also tested a version of Qwen without vision which is a nice boost to memory usage. So if you don't need vision that's a nice option. If you *do* want your local model to have vision..

I’m stripping the 333 vision tensors from Qwen 3.6 and it feels like I’m rather unqualified to poke the poor models eyes out 🥹 sorry please don’t have your robot friends run me over when they spot me on the streets.

Tijs Teulings 🦑 @tijs.org · 06/09/2026
Ornith 1.5 seems to hit a sweet spot for my M1 + Mei (MLX) setup. It’s a fairly large 35B model, but its MoE design only activates about 3B parameters for each token. Its hybrid design also does less full attention than a conventional model, so it doesn’t hammer memory and the KV cache as hard

Frontier AI models are converging on similar intelligence, yet cost per task can still vary 10x-60x across vendors. That seems unsustainable as models become more substitutable. A lot of frontier lab economics depend on customers paying huge premiums for increasingly marginal intelligence gains.

And if you just want a nice Mac app instead of messing around with alpha software and command line stuff (no worries I get it) you should checkout osaurus.ai Mei is based on some of their open source work (but Mei is more memory efficient and faster 😛) and it’s quite good and has a cute logo

If you have a Mac you can just use the passwords app. It’s perfectly fine now. It has the family sharing, the one time token. It works. You don’t need an extra app for this never mind paying a subscription fee. Save that money and donate it to whatever is your local version of the ACLU instead.

tldr; you can run Ornith 1.5 35B on a 32GB M1 Mac Studio at 50 tokens/sec and get Luna (or Qwen 3.8 27B) level intelligence at proper speeds. And you can do it with an MLX based inference engine you could embed in your own swift app. So much ground to still discover.

If you were following progress on my little quest getting a decent model working on my M1 Mac with only 32GB ram I have some updates. Phase 1 of github.com/tijs/local-m... is basically done. There I figured out a few viable models and which inference engine to run them on. Llama.ccp ended up..

This is the updated summary after the lastest round of testing btw (small but useful models running locally, M1 32GB) github.com/tijs/local-m...
Horizontal bar chart titled “Best overall — composite score by model,” ranking local LLM configurations by a composite benchmark score combining pass rate, speed, time, and turns. The top models are Ornith-1.5-35B-A3B GGUF at 0.591, the same model via llama.cpp at 0.586, Laguna-XS-2.1 at 0.560, and HaUncensored-35B-A3B at 0.554. Scores decline through several Qwen3 and LFM2.5 configurations to 0.063; one LFM2.5-2.6B GGUF configuration failed the usefulness gate.

Ok so I’ve now tried three different MLX implementations for a local inference engine and all of them collapse when handed more than a few thousand tokens to <1 token/sec. All in the server wrapper though so I see some potential for making a native swift version to resolve this..
