GoodSender

What it does

GoodSender is an email API that earns deliverability instead of fighting for it. Permission is enforced at the API: recipients confirm before you can send marketing email. Engagement is monitored automatically — unsubscribes and complaints are suppressed instantly. Transactional templates (OTP, Login, MFA, Order Completed, New Device) ship without consent. Pass markdown, HTML, or plain text in one HTTP call. 100,000 emails/month free, $1 per 100K beyond. Built by the SendGrid co-founder.

  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…
