TPU INFERENCE EXTERNALIZATION FULL STEAM AHEAD

Google's TPUv7 Ironwood delivers up to 50% better performance per dollar compared to Nvidia's B200/B300 chips. Ironwood is the first generation in which Google is competing for others' inference workloads with chips that can be purchased outright or rented through its own cloud. Google has decades of software engineering experience, so external TPU software should mature rapidly. This article takes a look at the TPU system and discusses the steps needed to make the stack widely available.

PROMPT INJECTION THROUGH TOOL OUTPUT

Prompt injections hidden in tool results can evade conventional safeguards because input and action screens inspect separate moments of an agent loop. The proposed signal is a “precedent gap,” where an agent suddenly makes a tool call or uses arguments absent from its execution history.

This developer wanted a tool that runs in the background and automatically scans sites so they can avoid AI-generated text in the first place. This post details how they developed Deckard, a Chrome extension that uses a locally-run model to mark AI-generated text.

HIP-AGENT: A HARNESS THAT FITS IN THE PROMPT

hip-agent is a small agent harness designed for agents. The configuration is environment variables, actions are shell commands, and a subagent is a child process. The rest is handled by existing protocols and formats. The core loop is about 200 lines of Python and a module for the Codex API.
