How did people in 1913 see the world? How did they think about the future? We trained LLMs exclusively on pre-1913 texts—no Wikipedia, no 20/20. The model literally doesn't know WWI happened. Announcing the Ranke-4B family of models. Coming soon: github.com/DGoettlich/his…

Very happy to announce the release of our latest Mistral OCR, which significantly outperforms existing solutions! A lot of effort was done to improve handwritten content, low quality scans, and complex tables & forms commonly found in enterprise documents.

Stanford just made fine-tuning irrelevant with a single paper. It’s called Agentic Context Engineering (ACE) and it proves you can make models smarter without touching a single weight. Key takeaways (and get the 23 page PDF):

The new @AnthropicAI Opus 4.5 model is absolutely stunningly good at literary analysis. I'm helping a friend with their book and there's times I feel like something is a little off in the writing, and when I ask Opus about it, it always diagnoses it beautifully, with examples.

This is literally my new workflow now: Real-time search → Grok 4.1 Fast Planning → Grok 4.1 Thinking Frontend Coding → Gemini 3 Pro Backend Coding → Claude Code (Opus/Sonnet 4.5) Write Tests → Gemini 3 Pro Run Tests → GPT-5.1 Codex Debug → Claude Opus 4.5 Bookmark this.
