Sealch is an email verification service that runs the same live SMTP check as the premium tools — catch-all detection, 99.2% accuracy, and you're never charged for unknowns . All at $0.35 per 1,000 instead of $8. Sealch runs the same email verification service as the premium tools — live SMTP, catch-all detection, and disposable filtering — at a fraction of the cost. Engineered for outbound teams who can't afford bounces, deliverability drops, or blacklisted domains. Every address is checked against the recipient mail server in real time.

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years.

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…
