AI Now cannot connect to SiliconFlow API (configured correctly but fails)

[KidKing666]

Describe the bug
I am unable to use SiliconFlow API in AI Now even though the configuration is correct.
The Python test script can successfully call SiliconFlow API (status 200), but when using AI Now's built-in model call function, it always fails with:
"AI Now failed to get a response from the model provider."
This suggests the issue is within AI Now's internal compatibility layer, not the API key or network.

To Reproduce

1. Configure SiliconFlow as a custom OpenAI-compatible provider in AI Now.
2. Set base_url: https://api.siliconflow.cn/v1
3. Set correct API key and model: deepseek-ai/DeepSeek-V3.2
4. Save configuration and restart AI Now
5. Send a simple prompt -> Observe failure

Expected behavior
AI Now should successfully call SiliconFlow API using the provided configuration..

Screenshots

Additional context

• Python test script confirms API key/network/model are valid (status 200)
• Issue only occurs in AI Now, not in direct Python requests
• AI Now seems to force GitHub Copilot compatibility patches, which may break SiliconFlow
• Configuration keeps being reset or not persisted
