What issue are you seeing?

When using a local model with LM Studio, which I have hosted on a different PC in the same network, the base_url, which contains the IP adress of the other computer, is ignored. This is my config.toml:

model_provider="lmstudio"
model = "qwen3-coder-30b"

[model_providers.lmstudio]
name = "lmstudio"
base_url = "http://xxx.xxx.xx.xx:1234/v1"

[profiles.qwen3-coder-30b]
model_provider = "lmstudio"
model = "qwen/qwen3-coder-30b"

After the CLI fails to connect it shows this error: Connection failed: error sending request for url (http://localhost:1234/v1/responses), which means that it didn't use the IP from the base_url but the localhost URL.

What steps can reproduce the bug?

Host a local model in you local network on a different machine and do the config as above.

What is the expected behavior?

It is supposed to use the base_url, otherwise it is not able to connect, since the URL is false.
