Mirendil released Fern 0.1 — its first model, pre-trained from scratch and designed for a context up to 10 million tokens. According to MarkTechPost, the model is oriented toward research and development tasks in the field of agent AI.

In the RULER single needle test on a context of 10 million tokens, Fern 0.1 achieved a score of 100%. At the same time, in code-agent development tasks it lagged behind leading models.

The practical significance of the launch is the combination of a very long context with purported emphasis on AI-agent work. Available materials are metadata and an excerpt of the MarkTechPost publication, so details of training, availability and comparative testing remain undisclosed.
