Introducing the Arcee AI Trinity Models @juliensimonfr

Uploaded December 2025 | Updated September 2026, 2 weeks ago

In this video, I discuss the new Trinity models that @ArceeAI just released (Trinity Nano Preview 6B and Trinity Mini 26B, both mixture of experts models). I am SUPER IMPRESSED by their quality, their speed, and their low price. And they have an Apache 2.0 license. Any serious AI practitioner needs to take a look NOW.

$Open-source Coding with Cline and Arcee Trinity Large I built a code review app powered by @ArceeAI s new Trinity Large model and deployed it to a @HuggingFace Space. In this video, I use the Cline AI coding assistant with Trinity Large to explore and enhance the code review app. Open-source coding all the way! Try the app yourself and let me know what it catches in your code. ⭐️⭐️⭐️ More content on Substack at https://julsimon.substack.com ⭐️⭐️⭐️ Trinity Large is a 400B parameter Mixture-of-Experts model trained in 33 days for $20M — a fraction of what frontier labs spend. It has 256 experts but activates only 4 per token, so only 13B active parameters do the work. That translates to 2-3x faster inference than anything in its weight class, which you can feel in the demo when reviews come back in seconds.
