Mirendil

Former Anthropic researchers building self-accelerating AI R&D. Mirendil describes itself as a frontier lab with a singular focus on AI R&D: it trains models that are exceptional at research and redesigns the entire lab around them so the full loop runs faster, more capably and more autonomously, with the stated aim of making self-accelerating AI R&D widely accessible rather than confined to a few labs (site, launch thread). In this corpus it appears at launch in the Claude Mythos leak issue, where the author reads it as a bet that the next leap comes from rethinking the loop rather than scaling weights, alongside the Agentica scaffolding result. Within the recursive self-improvement theme it is an early company founded on the loop itself as the product, months before Recursive Superintelligence’s $650M raise and the company founded to automate the scientific method.
