GPT-6.1 Terra + 9 AI Updates That REALLY Matter
GPT-6.1 Terra built a 3D tram in Blender from one photo and one sentence. That's one of ten AI updates from 26–30 October 2026, and we tested five of them ourselves: LFM3 and llama.cpp on a Mac, the Codex 0.166 upgrade, n8n 2 → 3 in Docker, and GitHub Agentic Workflows on our own repository. Every example in the video is real, and the screen says where it came from. What you'll learn: → What GPT-6.1 Terra costs ($1 per million input tokens, half the old Terra) and which claims nobody else has checked yet → Who gets up to $500 a month of free OpenAI API credits, and the two limits → Why Mistral Large 4 is a 1,060 GB download, and what its licence allows → LFM3 running on our Mac: a 1.1 GB file, the same answer three times → What llama.cpp 0.8.0's release notes say, and what the code shows → How Copilot Fusion picks a model, and what it costs → What broke when we upgraded n8n to 3.0, even after its Migration Report → GitHub Agentic Workflows: our 45-line file, the 2,139-line Actions file, and why our run didn't start Honest trade-offs: Terra's and Fusion's best numbers are the companies' own; Mistral Large 4 needs a server full of graphics cards; LFM3 trails bigger models as a coding agent (Liquid's own words); n8n 3.0 is a one-way upgrade; Agentic Workflows still needs careful human supervision (GitHub's own guide). ⏱️ Timestamps 0:00 GPT-6.1 Terra built a tram 0:35 1.
