Directory structure requirement may be unnecessary for providers without namespaced model IDs

[Blues-star]

I have a question regarding the current directory structure requirement: If the model ID contains /, use subfolders. For example, for the model ID openai/gpt-5, create a folder openai/ and place a file named gpt-5.toml inside it.

However, some providers like Poe don't have this namespacing requirement for model IDs. From the OpenAI-compatible endpoint https://api.poe.com/v1/models, the model_id is returned directly without any / separator (e.g., Gemini-3-Pro).

In this case, is the subfolder structure still necessary? Because following the current subfolder convention would actually conflict with the official documentation examples, such as:

import os, openai

client = openai.OpenAI(
    api_key=os.getenv("POE_API_KEY"),
    base_url="https://api.poe.com/v1",
)

# Example: Using web search and thinking level with Gemini models
response = client.chat.completions.create(
    model="Gemini-3-Pro",  # No namespace prefix
    messages=[{"role": "user", "content": "What are the latest developments in quantum computing?"}],
    extra_body={
        "web_search": True,
        "thinking_level": "high"
    }
)

The example shows model="Gemini-3-Pro" without any provider prefix, which wouldn't map cleanly to a poe/Gemini-3-Pro.toml structure if we strictly follow the subfolder rule for provider organization.
