Sealvo

What it does

The USPTO retired TESS in 2023 but their new search tool still lacks the basics: no prosecution history inline, no owner portfolio, no clean filtering. Sealvo fixes that — search 15M records, see full prosecution history on every mark, filter by status/class/owner, view any owner's entire portfolio. Free. No account. No paywall. Built for founders doing pre-filing clearance and lawyers doing due diligence.

  Wallstreetlocal – View investments from America's biggest companies2024 · github.com · ▲299

  Hello Hacker News! My name is Anonyo, and I am a seventeen-year-old from Southeast Michigan. This is wallstreetlocal, my passion project for the last year (and a half). I've posted this before, but I've finally open-sourced this entire project, so I thought I'd post it again. Heres the short pitch. The Securities and Exchange Commission (SEC) keeps record of every company in the United States. Companies whose holdings surpass $100 million though, are required to file a special type of form: the 13F form. This form, filed quarterly, discloses the filer's holdings, providing transparency into…

  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…
