DEEPSEEK-MATH-V2

DeepSeek's new math reasoning model achieves gold-level performance on IMO 2025, matching recent results from Google and OpenAI. The approach trains an LLM-based proof verifier that serves as a reward model. This incentivizes the generator to verify step-by-step reasoning rather than just final answers, addressing the fundamental limitation that correct answers don't guarantee correct reasoning.

OPENAI CUTS OFF MIXPANEL AFTER ANALYTICS LEAK EXPOSES API USERS

OpenAI API users may be affected by a recent breach at data analytics provider Mixpanel. Only API users are affected - normal ChatGPT users don't need to take any action. The data includes names, approximate locations, operating system and browser details, and user IDs. OpenAI dropped Mixpanel as a result of the attack. It is also carrying out a wider security review across its vendor ecosystem.

GOOGLE CHANGES GEMINI 3 PRO FREE ACCESS LIMITS DUE TO ‘HIGH DEMAND'

Google has updated the access elements for Gemini 3 Pro. Free users are now only guaranteed basic access, where daily limits may change frequently when using Thinking with 3 Pro. The limits have likely decreased, given the industry's general demand trends. NotebookLM rolled back access to the new Nano Banana Pro-powered Infographics and Slide Decks for free users and implemented limits for Pro users.

02DEEP DIVES & ANALYSIS

THE MOAT OF THE SEARCH INDEX

ChatGPT surpasses Google's search by using an "agent" approach, extracting relevant information from multiple sources and synthesizing answers, which diminishes Google's traditional search index advantage. This method reduces the impact of any single search result's failure, although it struggles with long-tail, fresh, or SEO-heavy queries. The traditional search engine moat has largely vanished, with AI-driven models increasingly blending search capabilities.

BETTER AGENTS

Better Agents is a CLI tool and a set of standards for agent building. It makes coding assistants experts in any agent framework. The tool generates an AGENTS.md that ensures industry best practices. The CLI guides users through selecting a programming language, agent framework, coding assistant, LLM provider, and API keys.

COMPOUNDING ENGINEERING PLUGIN

The Compounding Engineering Plugin is a Claude Code plugin that transforms how developers plan, build, and review code using AI-powered tools that systematically improve their development workflow. Compound engineering is the idea that each unit of engineering work should make subsequent units of work easier, not harder. The plugin provides the tools to make compound engineering practical.

INTELLECT-3: A 100B+ MOE TRAINED WITH LARGE-SCALE RL

INTELLECT-3 is a 100B+ parameter Mixture-of-Experts that achieves state-of-the-art performance for its size across math, code, science, and reasoning benchmarks. It was trained with both SFT and RL on top of the GLM 4.5 Air base model. The researchers used a diverse and challenging mix of RL environments designed to enhance the reasoning and agentic capabilities of their model. Full details about the training are available.

OPEN DEEP RESEARCH

An experimental, fully open-source research assistant built on LangGraph that automates deep topic research by planning, gathering, and writing structured markdown reports—either via a human-in-the-loop workflow or a multi-agent architecture—with configurable models, search tools, prompting, and evaluation integration.

04MISCELLANEOUS

OFF-THE-RAILS COST

A 'wasted thread' is when a model starts spitting out tons of leaked thinking or repeating tokens. This usually means users have to abandon and revert the thread. 17.8% of all costs incurred by Gemini users in Amp were on 'wasted tokens'. This is more than 2x worse than Sonnet and almost 8x worse than Opus.

THE CURRENT STATE OF THE THEORY THAT GPL PROPAGATES TO AI MODELS TRAINED ON GPL CODE

The jury is still out on whether GPL propagation to models should be pursued or avoided. It is unlikely that it will become a reality any time soon. Current lawsuits are seeking injunctions and damages rather than the forced GPL-ization of models, so it is still a legally uncharted territory. We need to continue exploring how to make technology innovation and software freedom compatible.
