How to change the LLM with myselt model, like 'deepseek-v3-241226'?

[MyQiongbao]

I have a llm names 'deepseek-v3-241226' with deepseek-v3. I edit the project and add the enum in deepseek.

Predefined model names for common providers

model_names = {
"anthropic": ["claude-3-5-sonnet-20241022", "claude-3-5-sonnet-20240620", "claude-3-opus-20240229"],
"openai": ["gpt-4o", "gpt-4", "gpt-3.5-turbo", "o3-mini"],
"deepseek": ["deepseek-chat", "deepseek-reasoner", "deepseek-v3-241226"],
"google": ["gemini-2.0-flash", "gemini-2.0-flash-thinking-exp", "gemini-1.5-flash-latest", "gemini-1.5-flash-8b-latest", "gemini-2.0-flash-thinking-exp-01-21", "gemini-2.0-pro-exp-02-05"],
"ollama": ["qwen2.5:7b", "qwen2.5:14b", "qwen2.5:32b", "qwen2.5-coder:14b", "qwen2.5-coder:32b", "llama2:7b", "deepseek-r1:14b", "deepseek-r1:32b"],
"azure_openai": ["gpt-4o", "gpt-4", "gpt-3.5-turbo"],
"mistral": ["pixtral-large-latest", "mistral-large-latest", "mistral-small-latest", "ministral-8b-latest"],
"alibaba": ["qwen-plus", "qwen-max", "qwen-turbo", "qwen-long"],
"moonshot": ["moonshot-v1-32k-vision-preview", "moonshot-v1-8k-vision-preview"],
}

then, I open 127.0.0.1:7788 and select llm provider with 'deepseek', model name with 'deepseek-v3-241226' , after runing agent, with error :
INFO [src.agent.custom_agent] 开始调用模型 2025-03-24 17:31:35.902042

use deepseek-chat

My LLM is not the official Deepseek model. The API endpoint URL for invocation is of the format https://xxx.xxxxx.com/api/v3/chat/completions, and the model name is deepseek-v3-241226. How do I properly invoke it?
