summary: "Mirendil has launched Fern 0.1, its first AI coding model, which supports up to 10 million tokens and can process roughly 500,000 lines of code in a single context window. The model is a post-trained version of Mirendil-Base, a foundation model built in 3.5 months with one researcher and less than $10M in compute, and is designed for high-volume tasks such as auditing training data and reading agent traces end to end."
