Google unveils Gemini 3 AI model and AI-first IDE called Antigravity

OpenAI has introduced GPT‑5.1-Codex-Max, a new coding model available in its Codex developer environment. This model enhances AI-assisted software engineering with improved reasoning, efficiency, and interactive capabilities. It replaces GPT‑5.1-Codex as the default model, designed to handle complex software development tasks across multiple contexts.

Fetch AI, a startup led by Humayun Sheikh, has launched three interconnected products aimed at enhancing the ecosystem of AI agents. The new offerings include ASI:One, a personal-AI orchestration platform, Fetch Business, a verification and discovery portal for brand agents, and Agentverse, an open directory with over two million agents. This initiative seeks to establish a robust infrastructure for what Fetch describes as the 'Agentic Web.'

Alphabet Inc. shares increased by as much as 6.9% on Wednesday, marking the largest gain since early September. This surge in stock price follows a series of positive reviews for the company's latest AI model, Gemini 3, which has been praised for its advancements in coding and reasoning capabilities.

DeepMind has introduced AlphaProof, an artificial intelligence designed to tackle mathematical proofs. While it shows promise in handling math challenges, it currently requires some assistance to function effectively.

A new benchmark from Artificial Analysis has highlighted significant weaknesses in the factual reliability of large language models, with only four out of 40 models tested achieving a positive score. Google's Gemini 3 Pro emerged as the leader in this evaluation, despite high rates of hallucinations.

Oriol Vinyals, co-lead of Gemini, stated that the advancements in Gemini 3 are attributed to improved pre-training and post-training processes. This statement challenges the prevailing notion that gains from pre-training are diminishing. Vinyals emphasized the importance of these enhancements in the context of AI development.

DeepMind CEO Demis Hassabis has emphasized the importance of world models in the future of AI, while cautioning about a potential bubble in the artificial intelligence market. With the launch of Gemini 3 Pro, Google aims to strengthen its position in AI leadership, reflecting a long-term strategy that is beginning to yield results.

Google's latest AI model, Gemini 3, reportedly surpasses competitors in various benchmark tests. However, concerns about its reliability persist, raising questions about the sustainability of the current AI hype.
