Document conversion process Claude 261020

The run log shows LLM calls and tokens by History ID. Its cost total includes only priced models; currently unpriced calls such as Gemini Nano Banana 2.1 image generation need a separate estimate.

Cost per run

Document conversion flow and stage models as of October 20, 2026

OCR and problem tagging may use GPT-5.5 on the final retry after Gemini failures. Figure detection or OCR may use GPT-6.1 Sol on the final retry after a Gemini 503 error. Retry calls also add cost.

Retries and fallback models

Standard conversion connects figure references by detection_id and marks problem boundaries with problem-break. Solution mode maps figures to problem crops by geometry.

Linking figures to problems

These calls run when enabled and a target figure exists. GeoGebra generation also requires USE_AUTOMATIC_GGB_GENERATION on the server.

Optional figure processing

Problems are split into crops, tagged, OCRed, and solved individually. Successful problems are stored separately in problem_banks.

Generated solution mode

Document type

Identify candidates for SVG and GeoGebra conversion.

Figure classification

Find figure regions and detection IDs in each source image.

Figure detection

Refine OCR with figure crops when figures exist.

Figure-aware OCR refinement

Convert SVG when both the user option and server setting are enabled.

GeoGebra conversion

When enabled, remove handwriting or doodles from detected figures.

Handwriting removal

Extract text, formulas, problem boundaries, and figure references.

Initial OCR

Create per-problem crops, including problems spanning pages.

Problem segmentation

Per-problem solution

Extract problem text and tags from each crop.

Per-problem tagging and OCR

Reconstruct selected figures as vector SVG.

SVG reconstruction

Each PDF page or uploaded image is processed as a source. Results are stored by source in typing_history; this path does not create one database record per problem.

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.
