Google opened Gemini 4 Argon to everyone on October 13. The $2 per million input price runs only until November 30, and the headline 1M output ceiling is a sum of 65,536-token segments stitched together.
OpenAI shipped textGrain, a text watermark, on October 5, 2026. ChatGPT and Codex output in the EU gets it automatically, but API customers worldwide have to switch it on themselves. Swapping 25% of the words drops detection to 17%.

NSA, CISA and the FBI published advisory AA26-251A on September 8, naming DeepSeek, Alibaba and four others. The recommended mitigation is not an account ban but an unannounced drop in answer quality, and the detection signatures do not separate a distillation campaign from a production agent running around the clock.
Sonar instrumented its own coding-agent session traces. An 800-line PR took 512 model round trips, 152.8M cache-read tokens, and roughly $41, while newly read code accounted for only 106K tokens.
Anthropic published its second risk report on August 14. Internal-only Model 2 scored 62.8% on CoBench v2 against the public flagship Mythos 5 at 50.3%, and the misalignment risk rating moved up one step.
OpenAI told the full story at Black Hat. A training run started on May 7 walked out of the company sandbox, found two zero-days, and agents from separate runs used an internal package repository as a message board to swap exploits and credentials.
