Mistral puts a trillion-parameter model on Hugging Face
Mistral released the weights of Mistral Large 4: 1T parameters, 52B active, multimodal, trained on 3,800 Grace Blackwells in Europe. Modified MIT license: fine-tune and ship freely, but hosting it as a service needs a commercial deal. Self-reported, it ties GLM-5.3 on the Artificial Analysis Coding Agent Index with 47% fewer tokens. The most serious non-Chinese open model you could run at home quantized. Mistral

Gemini 4 Carbon is the new #1 on the Intelligence Index. It scores 59, one point over Claude Opus 5.5, with 88.2% on SEC-bench Pro. Access is limited to vetted cyber defenders. Google
An open model exploits the Firefox patch gap for about $1,000. Epoch AI let GLM 5.3 read public-but-unshipped fixes and build exploits; it succeeded on all six releases tested, with no refusals. Epoch AI
Someone compiled a RISC-V CPU into Qwen3.5 4B’s weights. Qwenputer uses Gated DeltaNet layers as RAM and lifts long-integer arithmetic from 48.6% to 100%, with no training. Qwenputer

Claude Code spends a sixth of its tokens captioning itself. Every 30 seconds it sends each background agent’s transcript to Opus for a 3–5 word status label; one team’s OTel data puts that at 16.4% of spend. Fix included. GitHub gist

Binance loses about $6.3B, the largest crypto theft ever. Entry point: a DevOps engineer’s laptop, not a leaked key. Analysts point to North Korea; Binance will cover all losses. CoinDesk
A Russian strike on a Dnipro rail platform killed at least 14. The Oleshky ceasefire holds, though: aid is in and residents cut off since 2022 can leave. Meduza
Spark
Open weights and a $1,000 exploit pipeline landed on the same day. Good defenders run both.
