ChangeSpec is an open specification for software change communication

What it does

ChangeSpec is an open specification for software change communication. It defines a standard event format that vendors use to publish changes - API updates, security advisories, terms of service edits, pricing adjustments - and that consumers use to receive and process them. Every software vendor ships changes. Breaking API changes, security patches, deprecations, TOS updates, DPA modifications. These changes arrive through scattered channels - blog posts, GitHub releases, email blasts, Slack announcements - with no consistent structure, no standard severity taxonomy, and no machine-readable format. Downstream consumers miss changes, build integrations that silently break, and fail…from github.com

  Needle: We Distilled Gemini Tool Calling into a 26M Model▲776

  Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
