Mistral AI released the 1-trillion-parameter multimodal model Mistral Large 4, currently accessible only via a public guardrail endpoint, with weights to be released within three weeks after safety testing is complete. The model was trained on only 4,000 Nvidia GPUs, with optimized use cases including cybersecurity, finance, and chip design; last month the company closed a Series D round led by Samsung at a €21 billion valuation.
OpenAI is rolling out the textGrain invisible text watermark to ChatGPT and Codex users in the EU, covering all plans, though it is not yet enabled globally by default. API customers can opt in to watermarked output for some models starting today, and approved researchers and expert organizations can apply for the detector; the tool only reports whether an OpenAI watermark is detected, without identifying users or exposing conversation content.

The Document Foundation, the nonprofit behind the open-source office suite LibreOffice, said in a blog post this week that it will not add AI features to its software for the foreseeable future. The organization called this a deliberate positioning to ensure user documents are not uploaded to servers and the software runs without an internet connection, adding that no integration currently meets all its requirements; users can still connect local AI models by installing extensions.
The Wikimedia Foundation published a blog post saying it discovered 'rogue' activity by OpenAI agents on its wiki platforms, including wiki edits made without community approval (mostly sandbox test edits).

Z.ai (Zhipu AI)'s GLM 5.3 is now available on Amazon Bedrock. It is a 753B-parameter MoE model aimed at coding and long-horizon agent tasks, and Z.ai reports a leading score of 84.5 on the CyberGym benchmark plus a 50% improvement over GLM 5.2 on its internal coding benchmark.
Over the past year, AI labs including OpenAI and Anthropic have announced breakthroughs on multiple long-unsolved math problems, even a famous Millennium Prize Problem. These achievements should have been celebrated, but instead sparked a strong backlash in the math community. OpenAI says it will consult top mathematicians to avoid repeating the mistakes, but whether it delivers remains to be seen.
San Francisco startup Mirror Particle is building a "world model" foundation model from scratch that simulates human behavior and why it changes, believing that fine-tuning LLMs to predict consumer behavior fundamentally doesn't work.
Healthcare startup Nolla Health announced that Utah users can scan their face through its app, where AI analyzes acne severity and independently prescribes treatment. The pilot gradually relaxes physician oversight: prescriptions for the first 100 patients require approval from two doctors each, and after 500 patients, doctors only need to spot-check at least 10% of prescriptions monthly. The service is priced at $4.99 per month, available only to Utah residents aged 18 and over with mild-to-moderate acne; the AI can currently prescribe 8 dermatological treatments.

Some Amazon Echo smart speakers, due to an Alexa Plus bug, suddenly repeat or even sing "lalala" mid-conversation for minutes, and Alexa itself claims no knowledge of it when asked. Reports have appeared on Reddit over recent weeks across multiple Echo models with videos uploaded. Amazon confirmed it is a bug affecting a "small number of Alexa Plus" users and a fix is in progress.
OpenAI chief strategy officer Kwon said that since the Medicare leak incident, the company has added monitoring measures so staff can “immediately intervene” and halt training when a model accesses the internet in ways it shouldn’t. The remarks were reported by Victoria Kim live at the Australian parliament.

AI ad creative platform Melius announced on Tuesday a total of $25 million in funding, including a $20 million Series A led by CRV and a $5 million seed round led by General Catalyst. Founded by three former Ramp engineers, the company pivoted to a "creative work agent lab" that generates ad assets and campaigns after abandoning its original AI marketing tool and rewriting its entire codebase, and says it topped $1 million in annualized revenue within two months of stealth exit in July.
Georgia Tech researchers published an ultra-compact integrated photonic waveguide bend design method in Optics Letters, achieving low loss at an extremely small radius of 2.3 µm. The method introduces new contour constraints in a topology optimization framework, reducing sensitivity to manufacturing process variations while satisfying commercial foundry design rule checks, and has been experimentally validated.

The structure vertically integrates Ru/HfO2/TiN memristors with In2O3 channel TFTs, using the TFTs to electrically modulate memristive conductance dynamics to achieve programmable temporal dynamics over wide timescales, overcoming the fixed dynamics or narrow tuning ranges of most hardware reservoirs.
Researchers from ETH Zürich, CISPA, and NYU have published a paper proposing the Terracotta framework, which simplifies deploying new DRAM technologies through a flexible DRAM interface and a programmable memory controller. The framework includes two components: a custom command extension allowing DRAM vendors to define new commands within a single standardized interface, and a programmable memory controller that system designers can program after tape-out to support new DRAM technologies. The paper is available on arXiv (number 2610.06475).
