Google unveils Gemini 4 Argon - initially only for trusted cybersecurity specialists

Google announced Gemini 4 Argon, a new model that according to the company has, among other things, the top score on the DeepSWE v1.1 coding benchmark (77.9 percent, compared with 74.2 percent for Claude Opus 5.5 and 74.1 percent for GPT-6 Astra) and can generate responses up to a million tokens long. For now, it is available only to trusted cybersecurity specialists in the Fairwind program, and without the safeguards that block hacking tasks. The company will open wider access, first in the paid API and for Google AI Ultra subscribers, only after strengthening the safeguards. The launch price is $2 per million input tokens and $10 per million output tokens.

OpenAI unveils Decisions API - the Luna model picks from preset options in a fraction of a second

At DevDay, OpenAI presented the Decisions API, in which the Luna model receives a predefined set of options, such as image classification categories or possible agent actions, and picks one of them in a fraction of a second. The service is in a limited preview for now and, according to TechCrunch, resembles the Jev model that the startup TypeSafe AI released in September. TypeSafe CEO Diogo Almeida responded on X with a joke about the start of the "clone wars."

OpenAI adds an invisible watermark to ChatGPT and Codex text in the European Union to comply with the AI Act

OpenAI announced on Monday, October 5, that in the coming weeks it will start adding an invisible watermark to text generated by ChatGPT and Codex in the European Union - a response to the AI Act's transparency rules, which have applied since August 2. The textGrain technology doesn't insert any symbol; instead, it steers word choice so that a detector can read the pattern. API customers worldwide can enable it from October 5; it is off by default. In OpenAI's tests, replacing 10 percent of the words with synonyms lowered detectability from about 92 to 66 percent, and replacing 25 percent lowered it to 17 percent, so initially only researchers and institutions approved by OpenAI will get access to the detector.
