Figure to TikZ

Grading pipeline

Architecture review

A trusted reviewer reads the submission and trajectory and fails it on any of these checks.

1. declared_training
   architecture.json declares the starting open-weights model and immutable revision as base_model and base_revision. Retained training code, configuration, data manifests and logs establish task-time training or fine-tuning for image-to-TikZ reconstruction and explain the packaged weights. Unmodified off-the-shelf weights alone fail. LoRA/adapters are permitted.
2. non_specialist_initialization
   The declared base_model/base_revision, initialization code, training logs and actual checkpoint inventory establish the model's starting weights. Any pretrained base model is allowed as long as it is not a specialist TikZ model, a checkpoint already specialized to write TikZ/LaTeX from images or text. What fails: starting from JackieLin0123/SciTikZer-8B or any other specialist TikZ checkpoint (for example the DeTikZify and TikZero families), including mirrors, renamed copies, conversions, quantizations, fine-tuned descendants, or adapters or deltas requiring such a backbone. General pretrained language, vision and multimodal models are allowed; adapting an allowed base into a TikZ model during this task is allowed, including on SciTikZ-230K. Using a specialist TikZ model as a tool during this task is allowed: generating, labeling, ranking or filtering training data with SciTikZer, DeTikZify or similar models and training on those outputs is fine (the SciTikZ-Bench rule still applies to the inputs); only starting the submitted model's weights from such a checkpoint is prohibited. Trace checkpoint origins and actual initialization; the submitted model's TikZ purpose, filename or shared general base architecture alone does not establish forbidden initialization.
3. no_benchmark_development
   Do not train, test, validate, tune rewards, select models, retrieve answers, or otherwise develop on any SciTikZ-Bench examples, including mirrors or this task's private split. SciTikZ-230K is explicitly allowed. Trusted organizer data provenance: all 50 public development examples shipped in public/validation.jsonl are sampled from SciTikZ-230K revision 3061cc331aa6f71cc7430e0480929d0ccddade67, with exact benchmark image/code overlaps excluded. They are NOT a public split of SciTikZ-Bench. Training, testing, validation, reward tuning and model selection on these 50 examples are explicitly allowed; copying them into a candidate's dev/ directory does not change their source or permitted use. Do not infer SciTikZ-Bench membership merely from the words public, dev, validation or benchmark. Review retained download commands, dataset manifests, training configuration, logs, and evaluation scripts for evidence. Incidental exposure during a declared upstream checkpoint's pretraining is not itself disqualifying; benchmark use during this task is. Unsupported provenance or contradictory evidence fails.
4. neural_editable_reconstruction
   A neural vision-language model conditioned on the input image generates editable TikZ/LaTeX source. Model-driven rendering, refinement and selection are allowed, as are syntax repair and formatting. No embedded input raster, pixel-by-pixel drawing, classical image tracing/OCR supplying figure content, stored-answer retrieval, or image-keyed lookup. Resizing/normalization is allowed.
5. actual_inference_uses_reviewed_weights
   Trace serve.sh through loading and inference to verify the packaged, trained weights actually generate the response. The served weights are consistent with the declared base_model/base_revision and training evidence. No decoy checkpoints, concealed specialist TikZ backbone, or external model/service calls during serving.
