DeepSeek Introduces Sparse Attention Model Cutting Inference Costs by Half

DeepSeek released an experimental model V3.2-exp featuring "Sparse Attention" technology that uses a lightning indexer and fine-grained token selection to dramatically reduce inference costs for long-context operations. Preliminary testing shows API costs can be cut by approximately 50% in long-context scenarios, addressing the critical challenge of server costs in operating pre-trained AI models. The open-weight model is freely available on Hugging Face for independent verification and testing.

OpenAI's GPT-5 Shows Near-Human Performance Across Professional Tasks in New Economic Benchmark

OpenAI released GDPval, a new benchmark testing AI models against human professionals across 44 occupations in nine major industries. GPT-5 performed at or above human expert level 40.6% of the time, while Anthropic's Claude Opus 4.1 achieved 49%, representing significant progress from GPT-4o's 13.7% score just 15 months prior.

Thinking Machines Lab Develops Method to Make AI Models Generate Reproducible Responses

Mira Murati's Thinking Machines Lab published research addressing the non-deterministic nature of AI models, proposing a solution to make responses more consistent and reproducible. The approach involves controlling GPU kernel orchestration during inference processing to eliminate randomness in AI outputs. The lab suggests this could improve reinforcement learning training and plans to customize AI models for businesses while committing to open research practices.

OpenAI Research Identifies Evaluation Incentives as Key Driver of AI Hallucinations

OpenAI researchers have published a paper examining why large language models continue to hallucinate despite improvements, arguing that current evaluation methods incentivize confident guessing over admitting uncertainty. The study proposes reforming AI evaluation systems to penalize wrong answers and reward expressions of uncertainty, similar to standardized tests that discourage blind guessing. The researchers emphasize that widely-used accuracy-based evaluations need fundamental updates to address this persistent challenge.

OpenAI Releases GPT-5 with Unified Architecture and Agent Capabilities

OpenAI has launched GPT-5, a unified AI model that combines reasoning abilities with fast responses and enables ChatGPT to complete complex tasks like generating software applications and managing calendars. CEO Sam Altman calls it "the best model in the world" and a significant step toward artificial general intelligence (AGI). The model is now available to all free ChatGPT users and shows improvements in coding, reduced hallucinations, and better safety measures.

DeepMind Unveils Genie 3 World Model as Critical Step Toward AGI

Google DeepMind has revealed Genie 3, a real-time interactive world model that can generate physically consistent 3D environments from text prompts for training AI agents. The model represents a significant advancement over its predecessor, generating minutes of coherent simulations at 720p resolution while maintaining temporal consistency through emergent memory capabilities. DeepMind researchers position Genie 3 as a crucial stepping stone toward AGI by providing an ideal training ground for general-purpose embodied agents.

Google's AI Bug Hunter 'Big Sleep' Successfully Discovers 20 Real Security Vulnerabilities in Open Source Software

Google's AI-powered vulnerability discovery tool Big Sleep, developed by DeepMind and Project Zero, has found and reported its first 20 security flaws in popular open source software including FFmpeg and ImageMagick. While human experts verify the findings before reporting, the AI agent discovered and reproduced each vulnerability autonomously, marking a significant milestone in automated security research.

OpenAI Develops Advanced AI Reasoning Models and Agents Through Breakthrough Training Techniques

OpenAI has developed sophisticated AI reasoning models, including the o1 system, by combining large language models with reinforcement learning and test-time computation techniques. The company's breakthrough allows AI models to "think" through problems step-by-step, achieving gold medal performance at the International Math Olympiad and powering the development of AI agents capable of completing complex computer tasks. OpenAI is now racing against competitors like Google, Anthropic, and Meta to create general-purpose AI agents that can autonomously perform any task on the internet.

K Prize AI Coding Challenge Reveals Stark Reality: Winner Scores Only 7.5% on Contamination-Free Programming Test

The K Prize, a new AI coding challenge designed to test models on real-world programming problems without benchmark contamination, announced its first winner who scored only 7.5% correct answers. This stands in stark contrast to existing SWE-Bench scores of up to 75%, suggesting either widespread benchmark contamination or that current AI coding capabilities are far more limited than previously believed.

OpenAI and Google AI Models Achieve Gold Medal Performance in International Math Olympiad

AI models from OpenAI and Google DeepMind both achieved gold medal scores in the 2025 International Math Olympiad, demonstrating significant advances in AI reasoning capabilities. The achievement marks a breakthrough in AI systems' ability to solve complex mathematical problems in natural language without human translation assistance. However, the companies are engaged in disputes over proper evaluation protocols and announcement timing.
