Briefly

Last month in AI - November 2025
"November was the month AI went full gladiator mode: three frontier labs released their best models within a week, Google reclaimed the throne with Gemini 3, and open source proved it can win Olympic gold medals in mathematics. Meanwhile, the agent revolution became official doctrine at Microsoft and Google, and China's AI ecosystem hit escape velocity with 10 million app downloads in seven days."
"Gemini 3 Pro, launched November 18, sits at #1 on LMSYS Arena and tops benchmarks for text generation, image editing, image processing, and text-to-image. It solved 5 out of 6 IMO 2025 problems in "Deep Think" mode, a feat that would earn a silver medal at the International Mathematical Olympiad. The model was trained exclusively on Google's Tensor TPUs, not Nvidia GPUs, which sent Broadcom's stock soaring on chip demand and sparked a new hardware narrative: ASICs are back."
"Anthropic dropped Claude Opus 4.5 on November 25, right before Thanksgiving, and it's the efficiency king of November's model wars. It scores 80.9% on SWE-bench Verified for coding and research tasks, outpacing Sonnet 4.5 in both speed and cost. The price dropped 67% to $5 per million tokens, making it cheaper than Sonnet 4 for most workloads."
Three major frontier models launched in November and reshaped the competitive landscape. Google’s Gemini 3 Pro led benchmarks across text and image tasks, solved five of six IMO 2025 problems in "Deep Think" mode, and was trained on Tensor TPUs, renewing interest in ASICs; over one million users tried it in 24 hours and Google stock rose. Anthropic’s Claude Opus 4.5 emphasized efficiency and cost reduction, scoring highly on coding benchmarks and cutting price to $5 per million tokens. The agent paradigm became formalized at major cloud providers, and China’s AI ecosystem accelerated with ten million app downloads in seven days.
