    Tonight, I am releasing eight Gemma fine tunes and a beta of their combined mixture of experts model named GemMoE. GemMoE has ALL Gemma bug fixes built-in. You do not have to do anything extra to get great fine tunes/inference with it. It's a beast of a model. This would not

    Today was my last day at xAI. I was in charge of keeping people from making unauthorized changes to the system prompt. It sounds simple when I put it like that, but in practice, it was a game of cat and mouse. Some days, it felt like I was the only one standing between order

    Our customers needed a better base model <10B parameters. We spent the last 5 months building one. I'm delighted to share a preview of our first Arcee Foundation Model: AFM-4.5B-Preview.

    I'm excited to release a project I've been working on the last couple of weeks. Qwen1.5-8x7b: huggingface.co/Crystalcareai/… And the accompanying dataset created with the intention of encouraging MoE models to organically develop their own experts: huggingface.co/datasets/Cryst… The purpose

    We’re going permissive: Apache 2.0 across the board. AFM-4.5B is now relicensed from Arcee to Apache 2.0; the agent variant will launch under Apache 2.0; and all upcoming releases ship with open weights. Three models are in training.

    Arcee-Maestro-7B-Preview is out—our first reasoning model. This one isn’t distilled yet, but more is on the way. Arcee-Blitz is our 24B Mistral distillation from DeepSeek. We did continued pretraining distillation, using only our standard post-training distillation stack.
