Kolibri 1 and the European take on open-weight models: what Aleph Alpha shipped, and what it takes to run it
Models
· Kolibri 1 is Aleph Alpha's Apache-2.0 German-English 78B MoE. What the licence covers, how to run it, what the benchmarks show, and what 'European' means here.

Nex-AGI: Six Agentic Models, One of Which Fits Your GPU
Models
· Nex-AGI doesn't pretrain models — it post-trains other labs' open weights for agentic work, and six of the results are now in the library. Built on Qwen3.5 and DeepSeek bases, they run from 35B to 1.6 trillion parameters. Here's what each one is, where its numbers come from, and why exactly one of the six will load on a card you can buy.

The New Renaissance: What the Printing Press Actually Did, and What Open Models Are Doing Now
Models
· The printing press did not do what most people think it did. The Church was an early customer, not a panicked censor, and printing did not stay free. Read accurately, the fifteenth century says something precise about open-weight models — about why the narrow specialist is a 250-year-old industrial invention rather than a medieval one, and about which half of your craft just became free.

UNESCO's Nine Approaches to Governing AI — And What Comes After the Taxonomy
Privacy & Business
· UNESCO's 2026 policy brief maps nine approaches lawmakers are using to regulate AI, from principles to liability, illustrated with real laws from Brazil to South Korea. The taxonomy is useful — but none of the nine, by itself, guarantees an organisation can demonstrate what actually happened across the AI lifecycle. Here is the map, read against the primary source, plus the gap it leaves and the operational architecture that closes it: Policy to Risk to Decision to Action to Evidence to Accountability, and Governance to Runtime to Usage to Consumption to Cost.

Kimi Linear, Explained: The Attention Architecture That Beat Full Attention
Models
· Moonshot AI's Kimi Linear is the first architecture to beat full attention under a controlled comparison — while cutting KV cache 75% and decoding 6.3x faster at 1M tokens. Here's how Kimi Delta Attention actually works, transcribed from the open-source kernel: the state-update equation, why per-channel gating was the unlock, where the 75% comes from arithmetically, and what the paper does not prove.

PageIndex: The Vectorless, Reasoning-Based RAG Alternative (2026 Guide)
