I noticed that only selected [OpenRouter](https://openrouter.ai) models are available for PromptingTools.jl. How to use others e.g. the free ones for testing like [openai/gpt-oss-120b:free](https://openrouter.ai/openai/gpt-oss-120b:free)?

You should be able to use any openrouter model, since they can use OpenAI chat completions api.
The directions are in Using MistralAI API and other OpenAI-compatible APIs, where you insert your api key and the openrouter url for the model you want to use.

Indeed, in fact there is `OpenRouterOpenAISchema()` to make it easier, here’s an example:
```julia-auto
api_key = ENV["OPENROUTER_API_KEY"]
prompt = "Say hi!"
msg = aigenerate(PT.OpenRouterOpenAISchema(), prompt; model="openai/gpt-oss-120b:free", api_key)
```
Thanks @apo383 for the pointer!
