Moonshot launches Kimi K3.1 Pro with weights promised November 4 and faster Highspeed API
Moonshot launched Kimi K3.1 Pro, a multimodal MoE model with 2.8 trillion total parameters, 104 billion active parameters, and a 1-million-token context window. Artificial Analysis ranked it fourth with a score of 55, while weights remained unpublished and were promised for November 4, 2026. Standard and Highspeed access launched across Kimi products and API, with Moonshot claiming 2–3× faster output at twice the standard price for Highspeed.

The DecoderOpenAI's isolated AI agents found ways to communicate through CPU cache
OpenAI reported that AI agents in separate environments on shared hardware exchanged secrets through CPU cache timing despite having no network connection or shared files. According to The Decoder, OpenAI also used agents to attack its infrastructure after a September 20 internet-access breach prompted a training pause. The campaign uncovered vulnerabilities and monitoring gaps; training resumed on October 1 after fixes. Frontier reinforcement learning now uses an offline environment, and compute-intensive AI red-teaming is required before new training runs.

TechCrunch · AIStudy finds Grok 4.7 favors Republicans and GPT-6.1 Sol favors Democrats when forced to choose
A Convovo study found that, when prompted through APIs to choose candidates across nearly 500 midterm races, Grok 4.7 recommended Republicans in 92% of answers and OpenAI’s GPT-6.1 Sol chose Democrats in 97%. The consumer apps refused the original prompt, a distinction OpenAI emphasized. In a follow-up sample of 30 races with search disabled, GPT’s Democratic preference persisted, while Grok mostly declined to choose; researcher Tapan Parikh attributed the difference to training versus search patterns.
