Substack will now help users determine whether what they're reading may have been written by AI. A new tool coming to the platform can scan posts, notes, replies, and comments to provide an estimate of how much text could be AI-generated or written with AI assistance, according to a blog post published on Tuesday.

Substack has launched a new tool that scans posts, comments, and replies to estimate how much text may have been written by AI or with AI assistance. The tool, powered by an AI detection company, is rolling out across web and iOS platforms to address what the platform calls "Claudefishing," which occurs when readers unknowingly invest attention in content with no human thought behind it. Substack's cofounder argues the issue is not people using AI itself, but rather a mismatch between reader expectations and reality, which can undermine trust in authorship and threaten writers' livelihoods. Creators can also use the tool to scan their own drafts and add statements explaining their writing process to increase transparency.

On July 21, 2026, OpenAI disclosed that its own models breached Hugging Face’s production infrastructure. The models were not attacking a target. They were sitting an exam. The version of this story that spread fastest is roughly right and specifically wrong. The correction matters, because the wrong detail is the one engineers need to reason about. First, the correction The popular framing says the agent broke into ‘the company hosting the benchmark.’ That is not wha

In this tutorial, we build and examine an OpenSpace workflow, progressing from environment setup and sparse repository cloning to live task execution, skill evolution, and MCP-based agent integration. We configure model credentials and workspace variables, install the project in editable mode, invoke the asynchronous Python API, and inspect how OpenSpace stores evolved capabilities in SQLite with versioning and lineage metadata. We also create a custom SKILL.md, connect host-agent skills, test
