How to Determine the Exact Date a Model Was Used to Develop an App?

Hi everyone,

I’m conducting some analysis on Hugging Face, and I’m trying to figure out the exact date a model was first used to develop an app.

From what I understand, one possible approach is to scan app files and check when the model name first appeared in the app’s files. However, I’m wondering:

  • Is this the only way to determine this information?
  • Are there other methods, tools, or metadata available on Hugging Face that could help pinpoint this date more accurately?

I don’t think I can simply use the app’s first commit date as the adoption date of the model, because it’s possible that the app initially adopted Model A, and later, modifications were made to include another model. In such cases, how would I know the date when the second model was included?

Any insights, tips, or suggestions would be greatly appreciated. Thanks in advance!

  • Check Hugging Face model card metadata and API usage statistics for model updates and usage.
  • Review Git commit history in the app’s repository to track when the model was first added or modified.
  • Look at dependency management files in the app’s repo (e.g., requirements.txt).
  • Explore CI/CD pipeline logs or API call records to track model adoption through automated builds or inference.
  • Consider directly asking the developer or cross-referencing app release notes for more context.
