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.

DeepSeek's Reasoning Model Disrupts AI Industry and Raises International Concerns

DeepSeek's release of its R1 reasoning model has created significant industry disruption, displacing ChatGPT as the App Store's top app and prompting reactions from both tech giants and the U.S. government. The Chinese AI lab claims to have built its models more efficiently and at lower cost than competitors, though some remain skeptical of these claims.

Hugging Face Launches Open-R1 Project to Replicate DeepSeek's Reasoning Model in Open Source

Hugging Face researchers have launched Open-R1, a project aimed at replicating DeepSeek's R1 reasoning model with fully open-source components and training data. The initiative, which has gained 10,000 GitHub stars in three days, seeks to address the lack of transparency in DeepSeek's model despite its permissive license, utilizing Hugging Face's Science Cluster with 768 Nvidia H100 GPUs to generate comparable datasets and training pipelines.

Chinese AI Lab DeepSeek Releases Open Reasoning Model That Rivals OpenAI's Capabilities

Chinese AI lab DeepSeek has released DeepSeek-R1, an open reasoning model with 671 billion parameters under an MIT license, claiming it matches or beats OpenAI's o1 model on several benchmarks. The model, which effectively self-checks to avoid common pitfalls, is available in smaller "distilled" versions and through an API at 90-95% lower prices than OpenAI's offering, though it includes Chinese regulatory restrictions on certain politically sensitive content.
