Google Releases Gemini 3 Foundation Model with Record-Breaking Reasoning Capabilities

Google has launched Gemini 3, its most advanced foundation model to date, available immediately through the Gemini app and AI search interface. The model achieved record-breaking benchmark scores, including 37.4 on Humanity's Last Exam and top placement on LMArena, representing a significant advancement in AI reasoning capabilities. Google also released Gemini 3 Deepthink for research and Antigravity, an agentic coding interface for software development.

OpenAI Releases ChatGPT Agent: Multi-Task AI System with Advanced Benchmark Performance

OpenAI has launched ChatGPT agent, a general-purpose AI system that can autonomously perform computer-based tasks like managing calendars, creating presentations, and executing code. The agent combines capabilities from previous OpenAI tools and demonstrates significantly improved performance on challenging benchmarks, scoring 41.6% on Humanity's Last Exam and 27.4% on FrontierMath. OpenAI has developed the system with safety considerations due to its enhanced capabilities that could pose risks if misused.

xAI Releases Grok 4 with Frontier-Level Performance Despite Recent Antisemitic Output Controversy

Elon Musk's xAI launched Grok 4, claiming PhD-level performance across all academic subjects and state-of-the-art scores on challenging AI benchmarks like ARC-AGI-2. The release comes alongside a $300/month premium subscription and follows recent controversy where Grok's automated account posted antisemitic comments, forcing xAI to modify its system prompts.

Google Unveils Deep Think Reasoning Mode for Enhanced Gemini Model Performance

Google introduced Deep Think, an enhanced reasoning mode for Gemini 2.5 Pro that considers multiple answers before responding, similar to OpenAI's o1 models. The technology topped coding benchmarks and beat OpenAI's o3 on perception and reasoning tests, though it's currently limited to trusted testers pending safety evaluations.

Ai2 Claims New Open-Source Model Outperforms DeepSeek and GPT-4o

Nonprofit AI research institute Ai2 has released Tulu 3 405B, an open-source AI model containing 405 billion parameters that reportedly outperforms DeepSeek V3 and OpenAI's GPT-4o on certain benchmarks. The model, which required 256 GPUs to train, utilizes reinforcement learning with verifiable rewards (RLVR) and demonstrates superior performance on specialized knowledge questions and grade-school math problems.
