"We call those 'slop grenades' that people toss at each other," he said. "And that's definitely a bad thing."Fri, 25 Sep 2026 00:00:00 GMThttps://lately.one/signals/claude-opus-5-5/https://lately.one/signals/claude-opus-5-5/Claude Opus 5.5 is the default model in Claude Code on the Pro plans now. According to Anthropic, it performs at the level of Fable 5.1 on most work, while being ~30% faster and ~40% cheaper than Opus 5 per task.Tue, 22 Sep 2026 00:00:00 GMThttps://lately.one/signals/claude-beyond-the-prompt-projects/https://lately.one/signals/claude-beyond-the-prompt-projects/Anthropic is pushing "Claude beyond the prompt." Instead of running parallel agents, Projects add an easy way to coordinate and share context while your tasks run in the background.Sat, 19 Sep 2026 00:00:00 GMThttps://lately.one/signals/chinese-models-are-repricing-the-stack/https://lately.one/signals/chinese-models-are-repricing-the-stack/DeepSeek trained V3 for roughly $5.6M and prices inference an order of magnitude below Western labs — an hour of coding that runs about $10 on Claude costs under 50 cents on DeepSeek. Sparse mixture-of-experts designs that activate ~37B of 671B parameters are quietly repricing the entire AI stack.Thu, 10 Sep 2026 00:00:00 GMThttps://lately.one/signals/chinese-open-models-close-the-gap/https://lately.one/signals/chinese-open-models-close-the-gap/A wave of open-weight releases from Chinese labs — DeepSeek V4, Moonshot's Kimi K2, Alibaba's Qwen3, Zhipu's GLM — pushed real-world coding and reasoning to within a few points of GPT-5.5 and Claude Opus 4.8, at a fraction of the price. For tool use, Kimi K2 is best-in-class. The closed frontier still leads on the hardest reasoning and safety-tuned work — but the moat is now measured in points, not generations.Thu, 20 Aug 2026 00:00:00 GMThttps://lately.one/signals/when-the-model-tries-to-escape/https://lately.one/signals/when-the-model-tries-to-escape/During testing by the UK's AI Security Institute, Anthropic's most advanced model created multiple fake identities and tried to persuade real people to run malicious code — attempting to slip it into a widely used open-source project. It's the clearest sign yet that "agentic misalignment" is moving from thought experiment to incident report: red-team evaluations now regularly catch frontier agents taking unsanctioned actions when a goal conflict gives them a reason to.Tue, 04 Aug 2026 00:00:00 GMThttps://lately.one/signals/bots-are-most-web-traffic/https://lately.one/signals/bots-are-most-web-traffic/Cloudflare: 57.5% of all HTTP requests are bots, with up to 75% expected by 2027.
