How to know when a model is outdated ?

[mingodad]

I'm testing https://huggingface.co/chat/models/openai/gpt-oss-20b and there I asked this:

do you know any github repository created in 2025?

<p>Sure! Here are a few GitHub repositories that were created in 2025 (all with their public “created date” and a short description):</p>

Repository | Created | Short description | Link

open‑thoughts/open‑thoughts | 2025‑01‑27 | An open‑source platform for curating datasets that can be used to train and evaluate reasoning‑oriented language models. | https://github.com/open-thoughts/open-thoughts
 ...

But on https://huggingface.co/playground:

do you know any github repository created in 2025?

I don’t have any information about repositories that were created in 2025. My training data only goes up to September 2023, so I can’t see or reference anything that was added to GitHub after that date. If you’re looking for recent projects, you could search GitHub directly or use the GitHub API to filter repositories by creation date.

I'm asking it here because I don't know where else to ask, I also opened an issue here ggml-org/llama.cpp#15396 (comment) .

I've also downloaded the https://huggingface.co/openai/gpt-oss-20b and running locally it doesn't know anything from 2025.

Based on this I suspect that the model running here https://huggingface.co/chat/models/openai/gpt-oss-20b is not the one that's here https://huggingface.co/openai/gpt-oss-20b .

How/Where can we get the version running here https://huggingface.co/chat/models/openai/gpt-oss-20b ?
