Patch Notes

A running record of the changes shaping General Simulation Engine.

Version 1.2.0Build 56 · Current release
  1. 01

    Prairie Engine 1.2.0 / build 56

    Updated from version 1.0.3 / build 37.

    Release
  2. 02

    Three fixed Gateway routes

    Replaced the catalog-driven model menu with GPT-5.6 Sol (imaginative), GPT-5.6 Terra (balanced), and GPT-5.6 Luna (affordable). Terra is now the default.

    Models
  3. 03

    Strict model-roster enforcement

    Unsupported selections are rejected, and obsolete saved selections automatically migrate to Terra.

    Models
  4. 04

    Paper-and-ink model selector

    Placed directly on the connection screen with a “3 routes” label, then limited to the title page during normal use.

    Interface
  5. 05

    Running-world stamp

    Added the Prairie Labs / General Simulation Company™ stamp beside Reset while simulations are running.

    Interface
  6. 06

    Five rotating opening suggestions

    The opening prompt now fades between a Northern California lake, an abstract art museum, three boyband singers, a Prairie frontier town, and a neolithic settlement every three seconds.

    Opening
  7. 07

    A quieter wait state

    Replaced “the engine turns” with “be patient” / “the machine dreams,” and replaced the spinning wait cursor with the normal pointer.

    Interface
  8. 08

    Title-page cleanup

    Removed the lower-left prairielabs.ai credit from both the title page and generated-world specification; the title page now carries a small 1.2.0 version mark.

    Identity
  9. 09

    Stronger generated-page controls

    Only the required A/B/C buttons are allowed. Model-created Reset, model, menu, settings, replay, and other controls are rejected with a precise error.

    Guardrails
  10. 10

    Improved Gateway validation

    Connection validation now accommodates reasoning-heavy models that require a larger output-token allowance.

    Gateway
  11. 11

    Complete product notice

    Replaced the pending-counsel placeholder with a notice covering probabilistic output, possible inaccuracies, professional-advice limits, independent providers, privacy, availability, quotas, rates, and possible Gateway charges.

    Notice
  12. 12

    Redesigned installer

    The installer is now a consistent 660 × 400 paper-toned drag-to-Applications window with two 144-pixel icons and an embedded deterministic layout.

    One persistent world

    Stored the current world locally and restored it at launch so a simulation could continue across sessions.

    World

    Three-choice progression

    Advanced every running world through exactly three A/B/C choices at each turn.

    Vercel AI Gateway connection

    Connected the application to user-selected models through the user's own Vercel AI Gateway key.
