DeepSeek Resumes API Services After Capacity-Driven Pause

Chinese AI startup DeepSeek has reopened access to its API after a three-week pause caused by capacity constraints. The company's openly available R1 reasoning model has gained recognition for matching or exceeding the performance of OpenAI's top models, prompting competitive responses from both OpenAI and domestic rivals like Alibaba.

Anthropic Launches Claude 3.7 Sonnet with Extended Reasoning Capabilities

Anthropic has released Claude 3.7 Sonnet, described as the industry's first "hybrid AI reasoning model" that can provide both real-time responses and extended, deliberative reasoning. The model outperforms competitors on coding and agent benchmarks while reducing inappropriate refusals by 45%, and is accompanied by a new agentic coding tool called Claude Code.

xAI Launches Grok 3 Model Suite with Enhanced Reasoning Capabilities

Elon Musk's xAI has released its latest flagship AI model, Grok 3, trained with approximately 10 times more computing power than its predecessor using 200,000 GPUs. The release includes a family of models including Grok 3 Reasoning and Grok 3 mini, featuring specialized reasoning capabilities for mathematics, science, and programming, alongside a new DeepSearch feature for internet research.

Researchers Use NPR Sunday Puzzle to Test AI Reasoning Capabilities

Researchers from several academic institutions created a new AI benchmark using NPR's Sunday Puzzle riddles to test reasoning models like OpenAI's o1 and DeepSeek's R1. The benchmark, consisting of about 600 puzzles, revealed intriguing limitations in current models, including models that "give up" when frustrated, provide answers they know are incorrect, or get stuck in circular reasoning patterns.

Anthropic to Launch Hybrid AI Model with Advanced Reasoning Capabilities

Anthropic is preparing to release a new AI model that combines "deep reasoning" capabilities with fast responses. The upcoming model reportedly outperforms OpenAI's reasoning model on some programming tasks and will feature a slider to control the trade-off between advanced reasoning and computational cost.

OpenAI Cancels o3 Model in Favor of Unified GPT-5 Release

OpenAI has canceled its planned o3 AI model release, instead incorporating its technology into an upcoming GPT-5 release that aims to unify various capabilities including voice, canvas, search and reasoning. CEO Sam Altman announced that before GPT-5, the company will release GPT-4.5 (Orion) in the coming weeks, which will be OpenAI's last non-chain-of-thought model as the company fully embraces reasoning models.

Stanford Researchers Create Open-Source Reasoning Model Comparable to OpenAI's o1 for Under $50

Researchers from Stanford and University of Washington have created an open-source AI reasoning model called s1 that rivals commercial models like OpenAI's o1 and DeepSeek's R1 in math and coding abilities. The model was developed for less than $50 in cloud computing costs by distilling capabilities from Google's Gemini 2.0 Flash Thinking Experimental model, raising questions about the sustainability of AI companies' business models.

Google Releases Gemini 2.0 Pro with Enhanced Reasoning Capabilities

Google has launched Gemini 2.0 Pro Experimental, its new flagship AI model with improved coding abilities, complex prompt handling, and a 2 million token context window. The company is also making its reasoning model, Gemini 2.0 Flash Thinking, available in the Gemini app, while introducing a more cost-efficient model called Gemini 2.0 Flash-Lite that outperforms previous versions.

OpenAI Launches 'Deep Research' Agent for Complex Information Analysis

OpenAI has introduced 'deep research,' a new AI agent for ChatGPT designed to conduct comprehensive, in-depth research across multiple sources. Powered by a specialized version of the o3 reasoning model, the system can analyze text, images, and PDFs from the internet, create visualizations, and provide fully documented outputs with citations, though it still faces limitations in distinguishing authoritative information and conveying uncertainty.

OpenAI Launches Affordable Reasoning Model o3-mini for STEM Problems

OpenAI has released o3-mini, a new AI reasoning model specifically fine-tuned for STEM problems including programming, math, and science. The model offers improved performance over previous reasoning models while running faster and costing less, with OpenAI claiming a 39% reduction in major mistakes on tough real-world questions compared to o1-mini.
