  1. Cardano founder ships free code that strips Anthropic Claude watermarks

    Charles Hoskinson, the founder of the Cardano blockchain, has published a free open-source release that removes the watermarks Anthropic now attaches to Claude output. He calls it Anthropies. The release lands five days after Anthropic switched on invisible marking across every Claude product. The code appeared on GitHub under an Apache 2.0 license, so anyone can copy, modify, or sell it. Anthropic's mark is not a hidden character. A secret key steers tournament sampling, the step that breaks

  2. Study finds RL for reasoning changes only a few tokens, and you can copy the effect

    A new analysis of reinforcement learning for LLM reasoning suggests the field's biggest gains come from a surprisingly small change. RL is not rewriting how models think. It is nudging a tiny slice of the output. What the researchers measured Across several model families and common methods like GRPO and PPO, reinforcement learning reranks only 1.0 to 4.1 percent of tokens. The token it promotes is almost always already one of the base model's top five choices. Training, in other words, pushe

  3. DeepSeek V4 Flash tops charts but fails half its real agent tasks

    DeepSeek's V4 Flash has become the most-used AI model on OpenRouter and one of the highest-rated open-weight models available. In real agent tests, though, it finished barely more than half of the jobs it was given. The gap between leaderboard and workplace is the story. What Composio found The integration company Composio ran V4 Flash through eight agent harnesses, including Claude Code, Codex, and OpenCode, on 30 deliberately hard multi-step tasks. The tasks used live tools: Gmail, GitHub,

  4. Anthropic Investors Eye a $2 Trillion IPO

    Anthropic is preparing for a stock market debut that could value the five-year-old maker of Claude at more than two trillion dollars, according to investors cited by the Financial Times.

That would eclipse SpaceX and rank as the largest initial public offering on record. From a fraction o

  5. OpenAI Dissolves Preparedness Team, Reassigns Catastrophic Risk Work

    OpenAI shut down its "Preparedness" team at the end of July 2026, the team responsible for evaluating whether the company's AI models could pose severe or catastrophic risks. Its work on biological and cyber risks has been parceled out to existing teams, the Financial Times reported. The team, led by Dylan Scandinaro, assessed risks including biological weapons development, cyberattacks, and recursively self-improving AI systems. Scandinaro now focuses on safety risks from "recursively self-imp
