Gemini 3.8 Flash plans SVG and GGB corrections; gpt-image-2.5-flare draws the corrected figures. GGB corrections reference the previous SVG correction plan and image. Figures are stored as images, without individually editable points or lines.

Option 2-1 · Gemini + GPT Image 2.5 Flare

Highest difficulty design, independent review and accurate figures · isolated prompts

Advanced: import killer configuration

Killer option

Keep the original image and OCR; skip original SVG reconstruction and cached SVG reuse. Generate and validate the transformed figure with the same option 1-1 settings.

Process argon1014

Previous record: QuestiGeo 1014_1023

Classify the selected crop as geometry, algebraic, physics, or other and cache the result. Classification no longer shows a warning.

Classify before upload

Save each figure crop. Show the figure count multiplied by 500 credits and start processing only after the user agrees to the deduction.

Crop each figure and confirm 500 credits

Convert SVG1 to GeoGebra XML and GGB1, and show GGB1 as soon as it is ready.

SVG1 to GGB1

Load GGB1 and inspect its quality. Create GGB2 and replace the active GGB only when the corrected result is selected; retain GGB1 in history.

Load and review GGB; optionally create GGB2

Store the original image's problem OCR results in a separate JSON artifact.

Save problem OCR separately

Save SVG and GGB candidates with validation history, then settle the credit reservation for completed figures.

Save results and settle credits

Generate SVG1 directly from the crop without a construction plan, then show its thumbnail immediately.

Source crop to SVG1 and thumbnail

Compare the source crop with rendered SVG1. Create SVG2 and replace the active SVG only when a correction is needed; retain SVG1 in history.

Compare source and optionally create SVG2

QuestiGeo Process

Previous record: Process argon1015

QuestiGeo 1014_1023

Reuse the preflight classification cache when present. Without a cache, or when an old other-type result needs checking, classify as geometry, algebraic, physics, or other.

Classify figure type

The direct-upload worker detects the figure region within the chosen crop before OCR. It stops if several figures are found, then normalizes the crop to PNG. A cached detection skips the model call.

Detect and normalize figure crop

Generate GeoGebra XML from the chosen SVG and source image. Production pipeline 091720 selects the SVG candidate before conversion and may call the model again for fidelity repair.

Convert SVG to GeoGebra XML

Static integrity checks and headless GeoGebra loading/capture use no LLM. Visual review of source, SVG, and GGB capture, plus one possible repair, use gemini-3.8-flash. The default gate mode warns and can select the best candidate.

Load, review, and repair GGB

Read problem text, figure flags, and an optional bounding box from the original image. When several figures are present, use the chosen crop for context.

OCR and figure hints from original

Send the cropped image to /figures/classify-sources to classify geometry, algebraic, physics, or other. Pass the result to /figures and save it as the worker classification cache.

Classify the crop before registration

When needed, segment the original page and match the chosen figure to its problem. The selected-crop path for multiple figures can skip this call.

Segment problems and select context

Method A creates an optional matplotlib reference and structure plan. It was enabled in production. Other-type figures skip it; a recitation failure may use the gpt-6.1-sol fallback.

Method A Python reference and plan

Save SVG, GGB, XML, capture, thumbnail, checkpoints, and validation history, then finalize the conversion and credits. Saving calls no LLM.

Save artifacts and settle credits

If another SVG candidate exists, compare both with the source and select the more faithful one. A single candidate needs no comparison call.

Compare SVG candidates

Generate the first SVG candidate from the source figure, problem text, and optional Python reference, then parse, normalize, and check its geometry.

Reconstruct source SVG

When review feedback or the candidate policy calls for another version, generate a new SVG candidate from the original. Cache and validation results can skip this call.

Regenerate an SVG candidate

Compare the rendered SVG with the original for missing objects, intersections, labels, and typography, and provide feedback when another candidate is needed.

Review SVG and regenerate if needed

The browser crops the selected image and uploads both crop and original to storage. Browser processing and file transfer use no LLM.
