Hugging Face's FineEnvs team has released an open framework that turns unmodified coding-agent harnesses such as Claude Code, Codex and OpenCode into reinforcement-learning environments. In its own tests, one small model scored 62% in one harness and 33% in another. What a harness is, how the training works, and what the results do and do not show.

Samsung's third-quarter guidance points to about ₩107.4 trillion in operating profit on ₩195 trillion of sales, up from ₩12.17 trillion a year ago, with AI data-centre memory demand credited. AWS becomes a Platinum member of the Linux Foundation, with a board seat. What the numbers say and what they leave out.

A new benchmark, TasteVal, says the best AI model now reaches expert-level results on eight AI research tasks with 2.3 times less compute, though its authors list reasons that may overstate progress. Preference Model has open-sourced Karotte, a framework for training environments that are harder to game, and DatologyAI has released Zephon, a data loader that keeps experiments repeatable when the GPU count changes. What each claims, and who measured it.

Cognition has given its Devin coding agent a memory: short notes kept in a Git repository and tidied each night by a "dreaming" session, with the format open-sourced. Separately, Hark has released Hark Pro, a free assistant built on a model trained to use computers. What each launch is, and which claims are the companies' own.

Nous Research has raised $90 million to build Hermes for Businesses, a company version of its MIT-licensed Hermes agent. The raise is confirmed; the valuation is reported, mostly at $1.5B, with one $1.2B figure in circulation. Nous's "2.5% of global token usage" is its own estimate.

Open weights, serving runtimes and agents now fit together. Why open-source AI adoption is compressing from years of glue work to months.

If the Axios scoop is right, the open-weight field gets another entrant, and the top of the US market does not. Reflection has not confirmed it, and there is still nothing to download.

The AI infrastructure wars just got personal. Anthropic, the company behind Claude, announced this week that subscribers will no longer be able to use their Claude subscription...

Anthropic DMCA'd 8100 GitHub repos trying to contain the Claude Code leak. A developer rewrote it in Python before sunrise. 110K stars. The fastest repo in GitHub history. The genie is out of the bottle.
