Welcome to The Daily AI Briefing! Your daily dose of the most significant developments in artificial intelligence, cutting through the noise to bring you what truly matters in the evolving landscape of AI. I'm your host, and today we have a packed lineup of groundbreaking news and innovations that are shaping our technological future. In today's briefing, we'll cover Google DeepMind's official gold medal performance at the International Mathematical Olympiad, Alibaba's Qwen3 taking the open-source crown, a practical tutorial on creating an email-drafting AI agent, a revolutionary brain-inspired hierarchical reasoning model, plus trending AI tools and job opportunities. Let's start with Google DeepMind's remarkable achievement. Their advanced version of Gemini with Deep Think has officially achieved gold-medal level performance at the International Mathematical Olympiad 2025. Working directly with IMO officials, Gemini solved five out of six problems across algebra, combinatorics, geometry, and number theory, scoring 35 out of 42 points—officially reaching the gold-medal standard. Unlike OpenAI's similar claim, Google's answers were officially graded and certified by IMO coordinators using the same internal criteria applied to human competitors. This marks a significant advancement from last year when DeepMind earned silver using domain-specific translations, as this year's model tackled problems entirely in natural language. Moving to open-source developments, Alibaba's Qwen team has just claimed the open-source crown with their updated Qwen3 model. This non-thinking version activates 22 billion of 235 billion parameters with a 256K-context window, delivering performance that not only beats Kimi K2 across the board but also challenges top closed-source models like Anthropic's Claude Opus 4 and GPT-4o. Following community feedback, Alibaba separated its hybrid thinking approach, training instruct and reasoning models independently. The fully open-source model is now available as the free default option on Qwen Chat, Alibaba's ChatGPT competitor. For those looking to build practical AI applications, there's an interesting tutorial on creating an AI agent that drafts emails using xAI's Grok 4 model through n8n's workflow automation platform. The step-by-step guide walks you through adding a chat message trigger, configuring the Grok-4-0709 model with your API credentials, setting up memory nodes, and integrating with Gmail to create drafts. It's a perfect example of how frontier AI models can be harnessed for everyday productivity tasks. In a fascinating development for AI architecture, Sapient Intelligence has introduced the Hierarchical Reasoning Model, a brain-inspired open-source AI that delivers exceptional reasoning power with just 27 million parameters. The model uses three principles from cortical computation: hierarchical processing, temporal separation, and recurrent connectivity. With a high-level module handling abstract planning and a low-level one executing detailed tasks, the approach has beaten larger models like Claude 3.7 on complex puzzles without requiring extensive pretraining or chain-of-thought techniques. Some trending AI tools worth checking out include Google's Gemini Code Assist with its new agent mode, SOLO from Trae for full software development, Composite for turning your browser into an AI agent, and GEN for creating AI characters that build social media audiences end-to-end. As we wrap up today's briefing, we're seeing AI continue its rapid advance across multiple fronts—from solving Olympic-level math problems to open-source breakthroughs and practical applications that anyone can build. The brain-inspired approaches to AI architecture particularly highlight how the field is evolving beyond just scaling up existing models. Thank you for joining us on The Daily AI Briefing.
