Today, we’re excited to officially take AFM-4.5B out of preview and release the weights of both AFM-4.5B and AFM-4.5B-Base on @huggingface.
This marks a major milestone for our team at @arcee_ai as we open up access to a new, enterprise-grade language model designed for both flexibility and performance across a wide range of deployment environments.

fine-tuning — Taking a trained model and training it a bit more on your own examples so it gets better at one specific job.
open weights — A model whose trained parameters are published for anyone to download and run — unlike API-only models you can access but never possess.
Why it matters
