Image Test Lab
Upload one small benchmark worksheet, freeze two synthetic learner versions as the text-only benchmark, then compare the same question slots across low, medium and high image profiles.
Open this workspace to load the active test fixture.
1. Test fixture
The source is analysed once and retained privately for repeatable admin tests.
No fixture loaded.
2. Fixed test inputs
Select two to five top-level questions and configure exactly two synthetic students.
Upload a worksheet to select questions.
Build the fixed snapshot to preview the exact personalised questions used by every quality run.
3. Run production quality comparison
The fixed snapshot is the no-images benchmark. One click then creates three sequential child jobs. Customer credits are not charged; provider usage remains recorded as internal testing.

Emergency control
AI generation kill switch
Disabling this switch blocks new text and image API calls across server instances, aborts jobs that are still using the provider, and cancels queued or paused jobs with an idempotent credit refund. Jobs that have already finished all provider calls are allowed to save their completed worksheet so paid API work is not discarded. Cancelled jobs are never restarted automatically.
Loading generation-control status…
For an independent hard stop, set AI_GENERATION_ENABLED=false in Render. The dashboard cannot override that environment setting.
Provider-neutral API framework
Text and image provider routing
Configure one text provider and one image provider, with optional fallbacks. Provider selections are locked onto each new generation job and never change during an active generation.
Loading AI provider configuration…
Cost check: configured estimates are operational warnings, not guaranteed invoices. Verify the provider's current pricing before activating a new model.
Installed provider adapters
Credentials remain in Render environment variables. Tests use normalised diagnostics and do not display raw provider responses.
Provider calls and cost estimates
Estimated costs are shown alongside provider-reported costs where an API supplies them.
Published AI prompt guidance
Edit provider-neutral guidance. Code-controlled privacy, output-schema, answer-policy, safety and reconciliation rules remain locked.
