Introducing AFM, the Arcee Foundation Model

Today, we’re thrilled to unveil the Arcee Foundation Model, a new family of GenAI models built from the ground up for enterprise reality.

The first release — AFM-4.5B — is a 4.5-billion-parameter frontier model that delivers excellent accuracy, strict compliance, and very high cost-efficiency.

In short: enterprise-grade intelligence that can run anywhere — on a smartphone, at the edge, or in the cloud.

For a quick taste, you can test AFM-4.5B in our playground and on Together.ai.

For a deeper dive into the model’s training pipeline and benchmarks, details are available in our technical blog post.

PS: As we’ll now focus on our AFM foundation models, and because we love open-source, we’re opening up access to our previously closed-source language models. Details in the tech blog post.
