Big Chonk Energy

Mistral's new flagship, Mistral Large 4 — nicknamed "Le Chonk" — is a 1-trillion-parameter model and the biggest open-weight release to ship in Europe or the US this year, with weights dropping at the end of the month. It landed in the middle of a broader model pile-up — GPT-6 reached the free tier with "Intelligent UI," Anthropic shipped Claude Haiku 5.5, and Aleph Alpha and Reflection answered with the open-weight Kolibri and Beam. The week also brought the deaths of Margaret Hamilton, who led the Apollo flight-software teams, and Bob Cringely, the "Triumph of the Nerds" documentarian. And privacy kept surfacing: Anthropic reported a woman's Claude "diary" entry to police, Denmark disclosed an 8.8-million-person register breach, and a federal judge called Flock's plate tracking "indiscriminate mass surveillance."

Mistral opened a public preview of Mistral Large 4, a 1-trillion-parameter natively multimodal model with 52 billion active parameters, internally nicknamed "Le Chonk." The company says it outperforms any open-weight model developed in the US or Europe and is state-of-the-art among open models on enterprise workloads like cybersecurity, finance, and law. Weights drop at the end of the month; until then Mistral is red-teaming the model with partners and state authorities under reduced moderation.

OpenAI brought GPT-6 to the 1.2 billion people who use ChatGPT each week, adding "Intelligent UI" that answers with fully interactive interfaces and can build a small tool on the spot. A day later Anthropic released Claude Haiku 5.5, its cheapest and fastest small model, priced roughly 75% lower than Haiku 4.5 and pitched as a subagent for coding work alongside Opus 5.5 and Sonnet 5.5.

The open-weight side got crowded, too. Aleph Alpha released Kolibri, an English–German 78B Mixture-of-Experts model (3B active) with a 1M-token context under Apache 2.0, aimed at sovereign public-administration and aerospace work. Reflection introduced Beam, a 501B-parameter sparse MoE (23B active) pretrained on 23.8 trillion tokens and trained with a high-compute RL run of 100 million rollouts on 10,500 GB300 GPUs over four weeks.

Margaret Hamilton died at 90. She led the teams that programmed the Apollo guidance computers — more than 400 people across the Lunar Module and Command/Service Module flight software — and appears in the famous 1969 photo standing beside a stack of the listings her teams produced. Bob Cringely — Mark Stevens, an early Apple employee best known for the PBS documentary "Triumph of the Nerds" — also died this week, in his sleep.

Anthropic's safety systems flagged a Florida woman's Claude entries and a human reviewer reported them to police; she says she used the chatbot as a diary and wrote that she would attack a sheriff's office, and she now faces a second-degree felony under Florida Statute 836.10. Denmark's Central Person Register said an unauthorized party misused a company's legitimate access to pull names, addresses, and CPR numbers for about 8.8 million citizens. And in Tulsa, a federal judge ruled that a deputy's warrantless Flock license-plate search violated the Fourth Amendment, writing that tracking people's whereabouts becomes "constitutionally problematic when law enforcement can indiscriminately and passively catalog your whereabouts," and suppressed the resulting evidence as fruit of a poisonous tree.
