★ Ratings

  • 5: almost never fails, usable as-is
  • 4: one or two regenerations
  • 3: fun but inconsistent or weakly grounded

🔋 Tokens

  • Input: estimated at 1.3 Korean chars or 4 Latin chars per token
  • Text prompts use measured counts from a local Qwen2.5-14B run
  • One image ≈ 1,290 tokens on Gemini image models
  • Video and music bill per second, not per token

✅ Verification

  • Public result: several real outputs published by outlets or creators
  • Tested locally: text and settings prompts run on a local model to confirm format and intent
  • Translated prompts keep the original text under "Original text"

⚖️ Licensing and takedowns

  • Verbatim prompts come only from sources that permit redistribution (CC0, MIT, CC BY 4.0, official docs, public posts); each entry names its license and creator
  • Prompts reported by commercial outlets were rewritten by the editors with the same function; the source link is a reference, not a quotation
  • Result images are the creators' published outputs under their licenses; images showing identifiable real people are not included. Trademarks and characters appear for illustration and belong to their owners
  • Rights holders can request removal via Contact; we take it down on confirmation
  • Entries marked "written by Builderlog" are © Builderlog. Personal, non-commercial use in your own agent only. No commercial use and no copying, reposting or redistributing the text in whole or in part (blogs, social media, courses and paid materials included). Share by linking to the entry page. A license stated on the entry takes precedence
