Mirendil

Instead of using AI to assist researchers, Mirendil wants AI to do the research itself, and it has organized the whole company around that bet. It calls itself a frontier lab building systems that excel at AI research and development, with models trained for the job and a lab redesigned around them. The name comes from a word the company defines as friend of precious things, the hidden and undiscovered, meaning friend of discovery.

Lor, a lab made of agents

Lor is the product in private beta, with a waitlist. Its agents write code, run experiments and iterate for days on any machine, bringing up GPUs as needed and splitting a job across dozens or hundreds of parallel agents. People stay in charge of what to try and what to trust, and can follow or stop any agent. Lor runs frontier models from other developers as well as open-source ones, and is the home for Mirendil's own. The company says it runs on Lor every day. Example tasks include overnight ablation runs with a written report and a repository-wide security audit that opens a pull request for each fix.

Fern and the case for long context

Fern is Mirendil's first model, pretrained from scratch and post-trained from a base model called Mirendil-Base. Version 0.1 supports up to 10 million tokens of context, which the company equates to roughly 23 MB of code or half a million lines. Larger base models in the family, at 0.5 to 2 trillion and 2 to 10 trillion parameters, are listed as still in pretraining. Early access is by request.

One researcher, under $10M

The company reports that a single researcher working with agents pretrained its base coding model in 3.5 months using less than $10 million of compute. Its stated goal is to make frontier AI R&D reachable for scientists in fields such as drug discovery, chemistry, biology and robotics, which otherwise must become AI labs themselves.
