Fuel, range, time and running costs for boats, caravans, cars and road trips — calculated from current Australian prices, with the formula and its assumptions shown on every page. Daily averages on 19 August 2026 , from the ACCC weekly fuel price monitoring report. Per-city figures and the 2026 excise timeline . Daily averages on 19 August 2026 , against the same cities on 20 February 2026 — before the Middle East conflict and two changes to fuel excise moved the whole curve. Each of these is built around a question someone has to answer before committing money or fuel — not around a formula.

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…
