Claude OSS 350M

Disclaimer: This is not an official release by Anthropic.
Claude OSS 350M is an independent open model project.

Overview

Claude OSS 350M is a compact assistant model built to bring a familiar Claude-style feel into an edge-sized model.

In simple terms: this is an attempt to capture the habitual Claude-style tone and interaction pattern in a lightweight 350M-class model that is easier to run in constrained environments.

The model was fine-tuned on open-source datasets, with a combined total of approximately 200,000 rows collected from Hugging Face. The training focus emphasized assistant behavior, conversational tone, instruction following, and consistent identity in a small-footprint setting.

Claude OSS 350M is intended for:
