Anthropic Launches Opus 4.5 with Enhanced Memory and Agent Capabilities

Anthropic released Opus 4.5, completing its 4.5 model series, featuring state-of-the-art performance across coding, tool use, and problem-solving benchmarks, including being the first model to exceed 80% on SWE-Bench verified. The model introduces significant memory improvements for long-context operations, an "endless chat" feature, and new Chrome and Excel integrations designed for agentic use-cases. Opus 4.5 competes directly with OpenAI's GPT 5.1 and Google's Gemini 3 in the frontier model landscape.

Hugging Face CEO Warns of 'LLM Bubble' While Broader AI Remains Strong

Hugging Face CEO Clem Delangue argues that while large language models (LLMs) may be experiencing a bubble that could burst soon, the broader AI field remains healthy and is just beginning. He predicts a shift toward smaller, specialized models tailored for specific use cases rather than universal LLMs, and notes his company maintains a capital-efficient approach with significant cash reserves.

Google Releases Gemini 3 Foundation Model with Record-Breaking Reasoning Capabilities

Google has launched Gemini 3, its most advanced foundation model to date, available immediately through the Gemini app and AI search interface. The model achieved record-breaking benchmark scores, including 37.4 on Humanity's Last Exam and top placement on LMArena, representing a significant advancement in AI reasoning capabilities. Google also released Gemini 3 Deepthink for research and Antigravity, an agentic coding interface for software development.

OpenAI Criticized for Overstating GPT-5 Mathematical Problem-Solving Capabilities

OpenAI researchers initially claimed GPT-5 solved 10 previously unsolved Erdős mathematical problems, prompting criticism from AI leaders including Meta's Yann LeCun and Google DeepMind's Demis Hassabis. Mathematician Thomas Bloom clarified that GPT-5 merely found existing solutions in the literature that were not catalogued on his website, rather than solving truly unsolved problems. OpenAI later acknowledged the accomplishment was limited to literature search rather than novel mathematical problem-solving.

Anthropic Releases Claude Sonnet 4.5 with Advanced Autonomous Coding Capabilities

Anthropic launched Claude Sonnet 4.5, a new AI model claiming state-of-the-art coding performance that can build production-ready applications autonomously. The model has demonstrated the ability to code independently for up to 30 hours, performing complex tasks like setting up databases, purchasing domains, and conducting security audits. Anthropic also claims improved AI alignment with lower rates of sycophancy and deception, along with better resistance to prompt injection attacks.

South Korea Invests $390 Million in Domestic AI Companies to Challenge OpenAI and Google

South Korea has launched a ₩530 billion ($390 million) sovereign AI initiative, funding five local companies to develop large-scale foundational models that can compete with global AI giants. The government will review progress every six months and narrow the field to two frontrunners, with companies like LG AI Research, SK Telecom, Naver Cloud, and Upstage developing Korean-language optimized models.

Hugging Face Co-founder Thomas Wolf to Discuss Open-Source AI Future at TechCrunch Disrupt 2025

Thomas Wolf, co-founder and chief science officer of Hugging Face, will speak at TechCrunch Disrupt 2025 about making AI research and models open and accessible. The session will focus on how open-source development, rather than closed labs and big tech budgets, can drive the next wave of AI breakthroughs. Wolf has been instrumental in launching key open-source AI tools like the Transformers library and the BigScience Workshop that produced the BLOOM language model.

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.

Mistral AI Secures $14 Billion Valuation in Major European AI Investment Round

French AI startup Mistral AI is finalizing a €2 billion investment round at a $14 billion post-money valuation, making it one of Europe's most valuable tech startups. The OpenAI rival, founded by former DeepMind and Meta researchers, develops open source language models and has raised over €1 billion from prominent investors since its founding two years ago.

OpenAI Launches GPT-5 with Aggressive Pricing Strategy to Challenge Competitors

OpenAI released GPT-5, which CEO Sam Altman calls "the best model in the world," though it only marginally outperforms competitors like Anthropic and Google on benchmarks. The model is priced significantly lower than competitors, particularly undercutting Anthropic's Claude Opus 4.1, potentially sparking an industry-wide price war among AI model providers.
