Edited from the reconstructed week of February 3–9 and the original posts published February 17 and 24, 2025.

Introduction

February 2025

Major events

February was the month of the Paris AI Action Summit, and of the competing ideas of AI it put on one stage. France pitched its nuclear-powered electricity and announced €109 billion in prospective private investment; the European Commission launched InvestAI to mobilize €200 billion, including funds for AI “gigafactories”; European companies formed an AI Champions initiative. US Vice President JD Vance used the same summit to argue against heavy regulation. Days earlier, Google had dropped its pledge not to apply AI to weapons or surveillance.

The companies kept shipping. Google made Gemini 2.0 Flash generally available, Mistral took Le Chat to phones, Adobe and YouTube put generated video into creative tools, and xAI unveiled Grok 3 with reasoning models. Control was contested too: OpenAI’s board rejected a $97.4 billion offer from an Elon Musk-led consortium, publishers sued Cohere over their content, and South Korea’s privacy regulator saw DeepSeek’s app pulled from local stores while it addressed the country’s data law.

Patterns and trends

Two approaches to governing AI stood side by side: Europe paired large investment programs with the AI Act, whose first obligations had applied on February 2, while Washington argued that regulation would hold the industry back. Companies, meanwhile, moved to own more of what they depended on. OpenAI was reported to be finishing its first chip design, and Figure AI left its collaboration with OpenAI to build its own robot models. Research looked for cheaper routes to better models: Anthropic’s Constitutional Classifiers resisted jailbreaks in a public challenge, and the s1 experiment showed what a 1,000-example fine-tune plus extra thinking time could do.

Long-term threads

Europe’s program continued with the AI Continent Action Plan in April, the Code of Practice for general-purpose models in July and the obligations for those models in August. OpenAI’s chip work resurfaced in September reports of a chip built with Broadcom and in October’s 10-gigawatt agreement with the company. The Musk dispute moved to court with OpenAI’s countersuit in April. The Cohere case was an early sign of the copyright disputes that ran through the year, from June’s fair-use rulings on generative-AI training to Anthropic’s settlement in September. And DeepSeek’s trouble with privacy regulators, begun in Italy in January, now reached South Korea.

Week 6

February 3–9

Reconstructed in October 2026. Selections by Claude, ChatGPT, DeepSeek and Grok were compiled in 2026 and were not all independent: ChatGPT had read Claude’s draft; Grok received suggested stories; DeepSeek used sources supplied by the collection.

Constitutional Classifiers face adversarial testing

Anthropic introduced input and output classifiers trained with synthetic examples derived from written rules. The company reported stronger resistance to jailbreaks in its evaluations and opened a public challenge. Its earlier prototype had also imposed substantial computing overhead and rejected too many harmless requests.1

The work treated safety as a system-level engineering problem, with robustness, cost and ordinary usability measured together.

s1 explores reasoning with a small training set

The s1 researchers fine-tuned Qwen2.5-32B-Instruct on 1,000 questions paired with reasoning traces. Their “budget forcing” method controlled how long the model continued reasoning. The paper reported improvements on specified mathematics benchmarks and released the model, data and code.2

The experiment separated two ways to improve answers: fine-tuning an existing model and allocating more computation when it answers.

Google revises its AI principles

Google replaced its earlier framework with principles centered on innovation, responsible development and collaboration. The revised principles omitted the 2018 exclusions concerning weapons and surveillance that violated internationally accepted norms. Google linked the revision to global competition and the national-security interests of democracies.3,4,5

The change altered the company’s stated boundaries for acceptable applications of AI.

Figure ends its collaboration with OpenAI

Humanoid-robot maker Figure AI said it was leaving its agreement with OpenAI after a “major breakthrough” in robot AI built in-house. Chief executive Brett Adcock said that “to solve embodied AI at scale in the real world, you have to vertically integrate robot AI,” and promised to show something new within 30 days.7

The split showed robotics companies seeking to own the models that drive their machines, a year after the two companies’ partnership was announced.
