"Example of this can be anime models , where japanese artist names can affect the output greatly. \n",
"\n",
"Tokens with high ID will often give the \"fun\" output when used in very short prompts.\n",
"\n",
"# What about token vector length?\n",
"\n",
"If you are wondering about token magnitude,\n",
"Prompt weights like (banana:1.2) will scale the magnitude of the corresponding 1x768 tensor(s) by 1.2 . So thats how prompt token magnitude works.\n",

"# Disclaimer /Trivia\n",
"\n",
"This notebook should be seen as a \"dictionary search tool\" for the vocab.json , which is the same for SD1.5 , SDXL and FLUX. Feel free to verify this by checking the 'tokenizer' folder under each model.\n",
"\n",
"vocab.json in the FLUX model , for example (1 of 2 copies) : https://huggingface.co/black-forest-labs/FLUX.1-dev/tree/main/tokenizer\n",
"\n",
"I'm using Clip-vit-large-patch14 , which is used in SD 1.5 , and is one among the two tokenizers for SDXL and FLUX : https://huggingface.co/openai/clip-vit-large-patch14/blob/main/README.md\n",
"\n",
"This set of tokens has dimension 1x768. \n",
"\n",
"SDXL and FLUX uses an additional set of tokens of dimension 1x1024.\n",
"\n",
"These are not included in this notebook. Feel free to include them yourselves (I would appreciate that).\n",
"\n",
"To do so, you will have to download a FLUX and/or SDXL model\n",
"\n",
", and copy the 49407x1024 tensor list that is stored within the model and then save it as a .pt file.\n",
"\n",
"//---//\n",
"\n",
"I am aware it is actually the 1x768 text_encoding being processed into an image for the SD models + FLUX.\n",
"\n",
"As such , I've included text_encoding comparison at the bottom of the Notebook.\n",
"\n",
"I am also aware thar SDXL and FLUX uses additional encodings , which are not included in this notebook.\n",
"\n",
"* Clip-vit-bigG for SDXL: https://huggingface.co/laion/CLIP-ViT-bigG-14-laion2B-39B-b160k/blob/main/README.md\n",

"* And the T5 text encoder for FLUX. I have 0% understanding of FLUX T5 text_encoder.\n",
"\n",
"//---//\n",
"\n",
"If you want them , feel free to include them yourself and share the results (cuz I probably won't) :)!\n",
"\n",
"That being said , being an encoding , I reckon the CLIP Nx768 => 1x768 should be \"linear\" (or whatever one might call it)\n",
"\n",
"So exchange a few tokens in the Nx768 for something similiar , and the resulting 1x768 ought to be kinda similar to 1x768 we had earlier. Hopefully.\n",
"\n",
"I feel its important to mention this , in case some wonder why the token-token similarity don't match the text-encoding to text-encoding similarity.\n",
"\n",
"# Note regarding CLIP text encoding vs. token\n",
"\n",
"*To make this disclaimer clear; Token-to-token similarity is not the same as text_encoding similarity.*\n",
"\n",
"I have to say this , since it will otherwise get (even more) confusing , as both the individual tokens , and the text_encoding have dimensions 1x768.\n",
"\n",
"They are separate things. Separate results. etc.\n",
"\n",
"As such , you will not get anything useful if you start comparing similarity between a token , and a text-encoding. So don't do that :)!\n",
"\n",
"# What about the CLIP image encoding?\n",
"\n",
"The CLIP model can also do an image_encoding of an image, where the output will be a 1x768 tensor. These _can_ be compared with the text_encoding.\n",
"\n",
"Comparing CLIP image_encoding with the CLIP text_encoding for a bunch of random prompts until you find the \"highest similarity\" , is a method used in the CLIP interrogator : https://huggingface.co/spaces/pharmapsychotic/CLIP-Interrogator\n",
"\n",
"List of random prompts for CLIP interrogator can be found here, for reference : https://github.com/pharmapsychotic/clip-interrogator/tree/main/clip_interrogator/data\n",

"If you spot errors / ideas for improvememts; feel free to fix the code in your own notebook and post the results.\n",

"I'd appreciate that over people saying \"your math is wrong you n00b!\" with no constructive feedback.\n",
"\n",
"//---//\n",
"\n",
"Regarding output\n",
"\n",
"# What are the symbols?\n",
"\n",
"The whitespace symbol indicate if the tokenized item ends with whitespace ( the suffix \"banana\" => \"banana \" ) or not (the prefix \"post\" in \"post-apocalyptic \")\n",
"\n",
"For ease of reference , I call them prefix-tokens and suffix-tokens.\n",
"\n",
"Sidenote:\n",
"\n",
"Prefix tokens have the unique property in that they \"mutate\" suffix tokens\n",
"\n",
"Example: \"photo of a #prefix#-banana\"\n",
"\n",
"where #prefix# is a randomly selected prefix-token from the vocab.json\n",
"\n",
"The hyphen \"-\" exists to guarantee the tokenized text splits into the written #prefix# and #suffix# token respectively. The \"-\" hypen symbol can be replaced by any other special character of your choosing.\n",
"\n",
" Capital letters work too , e.g \"photo of a #prefix#Abanana\" since the capital letters A-Z are only listed once in the entire vocab.json.\n",
"\n",
"You can also choose to omit any separator and just rawdog it with the prompt \"photo of a #prefix#banana\" , however know that this may , on occasion , be tokenized as completely different tokens of lower ID:s.\n",
"\n",
"Curiously , common NSFW terms found online have in the CLIP model have been purposefully fragmented into separate #prefix# and #suffix# counterparts in the vocab.json. Likely for PR-reasons.\n",
"\n",
"You can verify the results using this online tokenizer: https://sd-tokenizer.rocker.boo/\n",

"The gibberish tokens like \"ðŁĺħ\\\" are actually emojis!\n",
"\n",
"Try writing some emojis in this online tokenizer to see the results: https://sd-tokenizer.rocker.boo/\n",
"\n",
"It is a bit borked as it can't process capital letters properly.\n",
"\n",
"Also note that this is not reversible.\n",
"\n",
"If tokenization \"😅\" => ðŁĺħ\n",
