A developer built an autonomous health agent that syncs Apple HealthKit data to Notion using OpenAI function calling. The system detects heart rate variability anomalies and automatically adjusts training plans or sugges…
A new paper argues that large language models (LLMs) are becoming consequential social actors as humans increasingly delegate deliberation to AI across health, law, finance, education, and personal guidance. The authors …
A new learning method called Socratic Spiral Learning leverages large language models like Claude Opus 4.8 and GPT-5.5 to teach technical subjects by revisiting material in layers of increasing depth, combining Socratic …
Claude Code, primarily known as a programming tool, can also be used to build a knowledge base, according to a guide on Towards AI. The article explains how to leverage Claude Code's capabilities beyond coding for knowle…
A new interactive visual explainer from Rudrite Research breaks down the concept of spurious rewards in reinforcement learning from verifiable rewards (RLVR), showing that even random or incorrect reward signals can impr…
The US government forced Anthropic to shut down API access to its Fable and Mythos AI models via export controls, citing national security concerns after another company demonstrated a way around the models' safeguards. …
The US government has ordered Anthropic to suspend access to its Fable and Mythos AI models for foreign nationals, including employees, drawing a line that treats the technology as too dangerous for non-Americans. This m…
A user discovered that Claude's deep research feature occasionally returns irrelevant or broken HTML in task titles, including unrelated topics like Hebrew calligraphy and SVG generation, suggesting a backend rendering r…
The US government used export-control authority to force Anthropic to recall its frontier AI models, Mythos and Fable 5, citing an unspecified concern with no statutory process or appeal. The author, who retained access …
Anthropic's Claude Fable 5 coding agent autonomously debugged a horizontal scrollbar issue in developer Simon Willison's Datasette tool by launching browser automation, building test pages, and patching CSS—all from a si…
David Sacks, former AI and crypto czar for the Trump administration, detailed the government's account of why it forced Anthropic to pull its Fable 5 and Mythos 5 models, citing a jailbreak that exposed advanced cyber ca…
The US government ordered Anthropic to suspend access to its Fable 5 and Mythos 5 AI models on June 12, 2026, citing national-security export controls. The directive bars access by any foreign national, forcing Anthropic…
Anthropic suspended access to its Claude Fable 5 and Mythos 5 models after the US Commerce Department ordered it to do so, citing a third-party report of a jailbreak method that bypassed safeguards. The suspension applie…
Rudrite Research published a comprehensive comparison of AI and ML approaches, covering 14 side-by-side analyses of techniques such as Transformers vs Mamba, FlashAttention vs PagedAttention, and PPO vs DPO vs GRPO. The …
Researchers led by Damani et al. introduced a method to train language models to express their uncertainty by adding a calibration reward to reinforcement learning from verifiable rewards (RLVR). The approach, detailed i…
A new interactive visual explainer from Rudrite Research demonstrates that large language model hallucinations are a predictable outcome of training and grading systems that reward confident guessing, based on a 2025 arX…
