   Mirendil releases Fern 0.1, its first model with a 10M-token context window

   AIMirendil has released Fern 0.1, its first AI model, a from-scratch coding model with a context window of up to 10M tokens, available only through early access. On RULER single-needle retrieval it scores 100% at every length from 32K to 10M tokens, but it scores 6.1% on Terminal Bench 4.0 against 66.4% for Claude Opus 5.5 in Mirendil's own table.

   Mirendil releases Fern, a model pretrained from scratch with 10M-token context

   AIMirendil releases Fern 0.1, its first model, pretrained from scratch with up to 10M tokens of context. The company says that is about 23 MB of code, roughly 500,000 lines, or several days of agent work held at once. Fern 0.1 received only a short round of post-training, and Mirendil says next-token prediction keeps improving as context grows to 10M.
