Changelog · October 2026

Blueprints on the new engine.

Everything Archie writes now comes from its new reasoning engine: conversations since September, plans and blueprints since October 5. Plan summaries keep up with their blueprints, the console is about four times faster, and Catio reads your code with sharper eyes.

BlueprintsPlansConsoleStacksPhase two

What this means for you

Optimize your architecture

Big plans finish.

Ask for a wide architecture plan and the new engine keeps working until it is done. No more coming back to a run that gave up at blueprint three. The summary and figures stay in step with the blueprints, so the big call rests on what the plan says today.

Build to aligned specs

A console that keeps up.

A typical page shows its main content in under a second, down from over three, and clicks and typing answer in about 16 ms. It works on a phone, so the plan review can happen in the taxi, if that is how you live.

Ensure it compounds

A sharper model of what runs.

Catio now tells a service from a worker, a batch job, a scheduled job or a command-line tool, across more languages and frameworks, and links each one to the infrastructure it really runs on. A worker filed as a service is a small mistake that becomes a wrong recommendation two steps later. Fewer of those.

In short
  • Plans and blueprints run on Archie's new engine. Every customer, nothing to turn on, since October 5.
  • A plan's summary and figures follow its blueprints within a couple of minutes, on their own.
  • The console is about four times faster at a typical page load, and works on phones.
  • Catio reads your code more sharply: more languages, five kinds of workload, correct links to infrastructure.
01

Blueprint generation, on the new engine

Ask Archie for a plan or blueprints and the new reasoning engine writes them, the one behind every Archie conversation since September. It keeps working on a large request until it is done. Every customer with Blueprints has it, nothing to turn on, since October 5.

OutcomeA wide architecture plan completes, however long it takes.

The September post promised this as phase two. Same grounding, same checks, same habit of showing its work, now applied to a whole program of blueprints. Older blueprints are untouched and keep their history. Nothing was reorganized while you slept.

02

Plans that stay current

A completed plan's summary and figures are written from the blueprints inside it. Add or remove a blueprint, edit a section, change a setting that moves the figures, or regenerate a blueprint, and the summary card says Pending update, then Refreshing, then Up to date, within a couple of minutes. Nothing to click.

OutcomeThe plan you review is the plan as it stands today.

A summary that drifts from its blueprints is how a program gets approved on numbers nobody re-checked. Now the page tells you when it is catching up, and when it has caught up.

03

A console rebuilt for speed and every screen

A typical page now shows its main content in under a second, where it took over three. The server answers in about 150 ms and clicks and typing respond in about 16 ms. It works on phones and narrow windows: tables wrap, buttons fold to icons, and dialogs no longer summon the keyboard uninvited. Buttons, colors, inputs and dates match across the product. Under Account, Appearance, pick a light, dark or system theme, larger text and reduced motion.

OutcomeLess time waiting on the tool, on whatever screen you have with you.

A faster console makes every other feature better for free. The figures come from real production page loads in mid October, at the 75th percentile. The samples are small. Every measure moved the same way.

04

Sharper understanding of your code

Catio reads your repositories to learn what runs, now across more languages and frameworks. It tells a service from a background worker, a batch job, a scheduled job and a command-line tool, gives each its own icon in Stacks, and links it to the infrastructure it runs on more reliably than before. Live since October 15; a workspace with source code connected gets it on its next run.

OutcomeDiagrams and answers that reflect what runs, read from the code itself.

The living model is only as good as its reading of your code. A job linked to the wrong cluster looks harmless right up until a recommendation is built on it.

What's next

Phase three

  • Archie in your coding assistant, over MCP. It already runs on the new engine; the public release is next.
  • The public API, with API keys you manage in Settings.
  • On-premises estates through Device42, and Azure.
  • Signed-off and Locked states on blueprints, so a ratified record stays ratified.
  • Archie learning from its own run history, with a person approving what changes.
