Researchers demo runtime 'Dynamic Abliteration' to suppress Qwen3-4B refusals

A technical write-up describes a method called Dynamic Abliteration that suppresses an open-weight LLM's refusal behavior without permanently altering its weights. Using Qwen3-4B as a proof of concept, the authors intercept intermediate residual streams at runtime via PyTorch forward hooks across multiple layers, injecting a steering signal derived from an 'Engram' approach instead of the traditional weight-projection abliteration technique.

Ando launches team chat app built for both human employees and AI agents

Startup Ando exited stealth Thursday with a messaging platform positioned as an alternative to Slack, giving AI agents their own identities and inboxes so they can join channels, DMs and calls alongside human coworkers.

Users can also describe an image, choose a style, or base a wallpaper on an existing photo or person, and the result is automatically sized for the iPhone screen.

Artificial Analysis publishes daily-updated chart ranking LLMs by price vs performance

Artificial Analysis maintains an Intelligence Index that plots large language models against their blended API cost per million tokens, using a 3:1 input-to-output ratio and a log-price scale. The tool highlights a 'value frontier' of models that aren't beaten on both price and intelligence by any other option, showing only top variants and hiding low scorers by default, with filters to expand the view.
