Free, no-nonsense calculators for UK tax, personal finance, home project costs and more. Clear answers, stated assumptions, sources you can check.

Straightforward tools for tax, money and real-world projects — with the assumptions and sources spelled out, so you can trust the number. Most online calculators hand you a number with no idea what it assumed or whether the figures are current. CalcFree does the opposite: every tool states its assumptions in plain English, links the official source, shows when it was last reviewed, and says clearly where an estimate ends and professional advice should begin. Pick a category to see every calculator in it. We add new tools regularly. Calculators for UK contractors, subcontractors and the self-employed — CIS refunds, umbrella vs limited company, side-hustle tax and company car tax. Estimate…from calcfree.online

  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…
