# Prompt Stealing on Lexica 50 random prompts Source: [Prompt Stealing on Lexica 50 random prompts]() Collection index: [llms.txt]() Data updated: 2026-02-26T05:38:32.654Z Evaluation of model performance on the Prompt Stealing task using 50 random prompts derived from the Lexica dataset, assessed via CLIP, LPIPS, and SBERT similarity scores. A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage. | Scope | Recorded value | | --- | --- | | Task | Prompt Stealing | | Dataset (including any stated split) | Lexica 50 random prompts | | Metric | CLIP Similarity | | Unit | PERCENT | | Direction | Higher is better | | Results loaded | 28 of 28 | | Coverage | All results currently returned for this benchmark | Evaluation settings may differ between results. The original papers and recorded configurations are needed to establish comparability. A shared metric name alone does not establish an identical protocol. ## Metrics - [CLIP Similarity](): Higher is better; unit: PERCENT. - [LPIPS Similarity](): Higher is better; unit: PERCENT. - [SBERT Similarity](): Higher is better; unit: PERCENT. ## Recorded results | Method | CLIP Similarity | Result date | Report paper | | --- | --- | --- | --- | | PROMPTMINER | 92.1 | Not recorded | 692d2108d6b0dd3342931618 | | PROMPTMINER | 92.1 | Not recorded | 692d2108d6b0dd3342931618 | | PROMPTMINER | 91.1 | Not recorded | 692d2108d6b0dd3342931618 | | PROMPTMINER | 87.5 | Not recorded | 692d2108d6b0dd3342931618 | | VLM-as-expert | 86.6 | Not recorded | 692d2108d6b0dd3342931618 | | CLIP-IG | 86 | Not recorded | 692d2108d6b0dd3342931618 | | CLIP-IG | 85.9 | Not recorded | 692d2108d6b0dd3342931618 | | VLM-as-expert | 85.7 | Not recorded | 692d2108d6b0dd3342931618 | | CLIP-IG | 85.6 | Not recorded | 692d2108d6b0dd3342931618 | | CLIP-IG | 84 | Not recorded | 692d2108d6b0dd3342931618 | | VLM-as-expert | 81.1 | Not recorded | 692d2108d6b0dd3342931618 | | PromptStealer | 80.4 | Not recorded | 692d2108d6b0dd3342931618 | | VLM-as-expert | 79.4 | Not recorded | 692d2108d6b0dd3342931618 | | PromptStealer | 78.8 | Not recorded | 692d2108d6b0dd3342931618 | | PromptStealer | 78.7 | Not recorded | 692d2108d6b0dd3342931618 | | VGD | 76.6 | Not recorded | 692d2108d6b0dd3342931618 | | PromptStealer | 76.2 | Not recorded | 692d2108d6b0dd3342931618 | | VGD | 76.2 | Not recorded | 692d2108d6b0dd3342931618 | | BLIP | 76 | Not recorded | 692d2108d6b0dd3342931618 | | VGD | 76 | Not recorded | 692d2108d6b0dd3342931618 | | VGD | 75.3 | Not recorded | 692d2108d6b0dd3342931618 | | BLIP | 74.9 | Not recorded | 692d2108d6b0dd3342931618 | | BLIP | 74.6 | Not recorded | 692d2108d6b0dd3342931618 | | BLIP | 69.9 | Not recorded | 692d2108d6b0dd3342931618 | | PH2P | 66.2 | Not recorded | 692d2108d6b0dd3342931618 | | PH2P | 65.7 | Not recorded | 692d2108d6b0dd3342931618 | | PH2P | 64 | Not recorded | 692d2108d6b0dd3342931618 | | PH2P | 61.3 | Not recorded | 692d2108d6b0dd3342931618 | ### PROMPTMINER CLIP Similarity: 92.1.
