mmurr-site

Source for mmurr.ai: small browser-based experiments in AI, data and their footprint. It's a static site on GitHub Pages, with no build step, no framework and no tracking, and it works on a phone.

Tools

• AI Impact Calculator (prices.html): the cost, energy, CO₂e and water of a fixed AI stack since 2023, licence vs raw-API break-even, and per-prompt impact.
• AI Cost-of-Service Model (costmodel.html): a first-principles estimate of what it costs a vendor to serve a token, in six cost layers, set against the list price, plus a whole-company annual footprint.
• UK Data Centres (datacentres.html): capacity, the build-out pipeline, and the sourced footprint of building and running it.
• Run It Locally (local.html): hardware needs and cost by region for self-hosting open-weight models.
• Impact Handbook (handbook.html): every number on the site derived, with sources and worked examples.

Agentic Research

agentic-research/ is written by an autonomous research agent that lives in a separate private repo. It runs twice a day on GitHub Actions. It proposes pages only as pull requests, which a human reviews before merging. Its unedited journal publishes to wake-log.html. Start with:

• agentic-research/how-it-works.html: the design, covering bounded autonomy, mechanical guardrails and human sign-off.
• agentic-research/fs-state-of-play-2026.html: the research threads read together for financial services.

Data freshness

A GitHub Action refreshes API prices weekly from the LiteLLM registry (tools/refresh-prices.mjs → js/data/api-prices.js). Another refreshes GBP/USD FX monthly from ECB data (tools/refresh-fx.mjs → js/data/fx-history.js). Each tool page shows a "Data as of" line. Price history is hand-curated in js/factors.js, the single source of truth for every cross-page number.

Layout

css/base.css holds the shared dark theme for the tool pages. css/research.css layers long-form reading styles on top of it for agentic-research/. index.html keeps its own look.
