"But marinade" and leaked passwords are what researchers found in ChatGPT's hidden reasoning

By Matthias Bastian

AI Analysis

Security researchers disclosed a vulnerability across OpenAI, Anthropic, and Google APIs that allows extraction of encrypted reasoning traces and cross-model transfer. Public scans already turned up dozens of leaked passwords and API keys, and surfaced that user-facing reasoning summaries often hide the models' actual behavior.

Security researchers found a vulnerability in the APIs of OpenAI, Anthropic, and Google that lets them extract encrypted reasoning traces and move them between models. A scan of public sessions turned up dozens of passwords and API keys. The traces also show that the reasoning summaries users see often hide what the models are actually doing.

[AINews] Muse Glimmer and Spark: Open Weights return Personal Superintelligence promise

By Unknown

80 score
AI Analysis

Continuing our coverage from yesterday, Meta released Muse Glimmer as its first substantive open-weights small LLM, accompanied by a Zuck essay reiterating Meta's personal superintelligence strategy. Muse Spark is slated for release soon and is positioned as part of an open-weights push that includes Muse Code.

Last week was the 1 year anniversary of Zuck’s original Personal Superintelligence essay, and MSL seems to be feeling a second wind this year, as they slowly ramped up with the Dreamer acquisition and then Muse Spark and recently Muse Code. For a while it seemed like MSL was being rather timid with the launches… but today that all changed. Zuck returned with a hit sequel essay and released MSL’s first real open weights frontier-ish small LLM, with Spark to also be released soon

AI Analysis

Nvidia released Nemotron 3.5 Lightning, an open-weights model with 3.6 billion active parameters that matches gpt-oss-120b on the Intelligence Index at roughly a quarter of the size. It runs near 670 tokens/second, the fastest in the comparison, positioning Nvidia on efficiency rather than raw scale.

Nvidia's Nemotron 3.5 Lightning is an open-weights model with just 3.6 billion active parameters that matches OpenAI's gpt-oss-120b on the Intelligence Index despite being four times smaller. At nearly 670 tokens per second, it's also the fastest model in the comparison, showing Nvidia is betting on efficiency over raw size.
