Anthropic released Claude Opus 4.5 on December 3, 2025, which outperformed all human engineering candidates in internal tests, marking a new benchmark in AI capabilities. OpenAI is developing a new model codenamed 'Garlic' that reportedly surpasses Google's Gemini 3, alongside prioritizing its Imagegen for ChatGPT.​

Key Developments

• French startup Mistral unveiled new models, while Amazon launched its latest AI chip to challenge Nvidia, intensifying the global AI arms race.​
• UC San Diego research showed OpenAI's GPT-4.5 passing the Turing test better than humans 73% of the time in short interactions, though not proving full AGI.​
• A UN report on December 2 warned AI could widen global inequalities, creating a 'great divergence' between developed and other states.​

Broader Trends

Fujitsu advanced multi-AI agent systems, and new research uses AI to model brain dynamics and behavior with tools like GPT-4. Experts highlight progress in reasoning, coding, and math competitions, but long-term AGI timing remains uncertain. Ongoing fragmentation includes European alternatives like Mistral and infrastructure plays by Amazon.​
