Mistral AI unveiled Mistral OCR 3, positioning it as a leader in document intelligence with superior accuracy and efficiency over enterprise solutions and rival AI-native OCR tools, particularly on challenging inputs like forms, low-quality scans, complex tables, and handwriting—boasting a 74% overall win rate against its predecessor while outputting clean text structured in markdown with HTML-style tables. The model is now accessible via API or the Document AI playground in Mistral AI Studio, marking a significant leap for real-world document processing applications.
In coding and cybersecurity realms, OpenAI launched GPT-5.2-Codex, hailed as the top agentic coding model for complex software engineering, featuring native compaction, enhanced long-context understanding, and refined tool-calling. It dominates benchmarks like SWE-Bench Pro and Terminal-Bench 2.0, building on GPT-5.2 and GPT-5.1-Codex-Max, with gains extending to cybersecurity—where a researcher recently used its predecessor to disclose a React vulnerability risking source code exposure. While empowering defenders, OpenAI emphasized dual-use risks, opting for gradual rollout: available now in Codex for paid ChatGPT users, with API access imminent and invite-only cyber tools for vetted teams.
Meanwhile, xAI's new Grok Voice Agent has surged to the forefront of speech-to-speech reasoning, maintaining Grok's overall dominance and fueling anticipation for upcoming releases like Grok 4.20 and Grok 5. On the integration front, Perplexity rolled out Gemini 3 Flash to all Pro and Max subscribers, broadening access to Google's latest lightweight powerhouse within its search ecosystem.
OpenAI accelerated its evolution into a full-fledged app platform by debuting the ChatGPT App Directory and Apps SDK, rebranding "connectors" as apps for seamless in-chat experiences like file search, deep research, and sync—now expanded with integrations for Spotify, Zillow, Apple Music, and DoorDash, alongside hints at future monetization via digital goods. This move transforms ChatGPT into a developer hub for interactive tools.
Bolstering scientific ambitions, OpenAI deepened ties with the U.S. Department of Energy, expanding collaboration on AI-driven advanced computing to propel national priorities, including the Genesis Mission for faster scientific breakthroughs at DOE national labs.
Yet, beneath the growth, challenges loom: reports detail how organizational missteps have stalled ChatGPT's momentum, as the research division chased slow-reasoning models unappealing to everyday users craving quick answers—yielding no paid subscriber uptick—while deprioritizing hits like image generation let rivals like Google close the gap, prompting a company-wide "code red" refocus on consumer appeal. Amid this, OpenAI eyes a colossal funding round at a $750B valuation, with talks for up to $100B in fresh capital fueled by ~$19B annualized revenue, speculating a potential $1.5T peak pre-IPO.
Chinese firm LimX Dynamics showcased a striking modular robot that underscores Beijing's inventive edge in AI hardware, adapting to chip constraints much like software teams optimize models for peak efficiency—a trend signaling broader shifts in robotics amid global AI hardware races.
"I love the expression 'food for thought' as a concrete, mysterious cognitive capability humans experience but LLMs have no equivalent for... So in LLM speak it’s a sequence of tokens such that when used as prompt for chain of thought, the samples are rewarding to attend over, via some yet undiscovered intrinsic reward function. Obsessed with what form it takes. Food for thought."
—Andrej Karpathy
Andrej Karpathy, the influential AI researcher, sparked viral reflection on LLM frontiers with this meditation on why large language models lack a "food for thought" analog—a nourishing mental stimulus for deep pondering—reframing it as intrinsically rewarding token sequences ripe for chain-of-thought prompting, hinting at untapped reward mechanisms in model cognition.
