Mirendil has released Fern 0.1, its first AI model, a from-scratch coding model with a context window of up to 10M tokens, roughly 23 MB of code. Built on Mirendil-Base, which was pretrained by one researcher with AI agents writing over 99% of the code for under $10M, Fern targets AI R&D tasks like large-codebase work and agentic coding. It achieves 100% on RULER single-needle retrieval up to 10M tokens but lags on agentic benchmarks, scoring 6.1% on Terminal Bench 4.0 versus 66.4% for Claude Opus 5.5. The model is in hosted early access with no open weights announced.
OpenAI says its internal AI models have cracked three major open questions in mathematics, computer science and physics, including one tied to a Millennium Prize Problem. Outside experts, among them a Nobel laureate, are now checking whether the proofs hold up. The report says a valid computer science proof could undermine hundreds of research papers, but the claims remain unverified.
Why it matters: Readers get an early look at a high-stakes expert verification process for claimed AI-generated proofs with implications across multiple research fields.
Baidu released Unlimited OCR 2, an open-source 3.34B vision-language model for parsing very long documents like books and filings in a single request. It introduces SR-SWA, a sparse attention mechanism that keeps per-step decoding costs nearly constant as document length grows. The model achieves 77.1 on MarathonDocBench, far ahead of competitors, though all benchmark figures are self-reported. Weights are available under the MIT license with code on GitHub.
