The DouBao large model and DeepSeek v3 model from VolcanoArk cannot be used via OpenAI-compatible connections and require API adapter for VolcanoArk's large model service platform.

The problem seems like, [Bearer Token] is not suitable for Roo-Code, so that we cannot use OpenAI Compatible provider to use these models like Baidu Qianfan ModelBuilder and luchentech cloud.

I found this problem too. But it can be used in chatbox with OpenAI Compatible provider.

Is there any solution to that?

I use these codes and work well. May be some adapter problems.

from openai import OpenAI

client = OpenAI(
    api_key="bce-v3/ALTAK-/f69945bc8704fe2cdf23",  # 千帆ModelBuilder平台bearer token
    base_url="https://qianfan.baidubce.com/v2",  # 千帆ModelBuilder平台域名
)

completion = client.chat.completions.create(
    model="deepseek-v3", # 预置服务请查看支持的模型列表
    messages=[{'role': 'system', 'content': 'You are a helpful assistant.'},
              {'role': 'user', 'content': 'Hello！'}]
)

print(completion.choices[0].message)

Thanks for flagging! Attached to #770 as iiuc these are essentially the same issue (need Volcano adapter.) If these are different provider support requests, please flag and we can decouple.
