No models

Error message

No models

What it means

`set_client_models_config` (src/client/common.rs:610) bails with 'No models' during client configuration when the collected model name list is empty — i.e. the user neither selected any models from the fetched /v1/models list nor typed any comma-separated model names at the interactive prompt. Configuration cannot proceed without at least one model.

Solutions

1. Re-run client configuration and enter at least one model name (comma-separated, e.g. llama3.3,qwen2.5) at the 'LLMs to add' prompt.
2. Ensure the server is running and api_base is correct so 'Fetching models' succeeds and the interactive multi-select is offered.
3. Set a valid api_key (config or <CLIENT>_API_KEY env var) so /v1/models can be fetched.
4. If the provider is a known one, use its built-in config path instead of the OpenAI-compatible generic flow.

Example fix

// before: empty input at 'LLMs to add' -> No models
LLMs to add: 
// after
LLMs to add: llama3.3,qwen2.5

let names: Vec<String> = /* collected from fetch or manual input */;
if names.is_empty() {
    anyhow::bail!("Please provide at least one model before configuring the client");
}

match create_openai_compatible_client_config(&client).await {
    Err(e) if e.to_string() == "No models" => eprintln!("Enter model names, e.g. llama3.3,qwen2.5"),
    other => other,
}

When it happens

Trigger: Running create_config / create_openai_compatible_client_config for an OpenAI-compatible client where: the fetch_models call failed (network/auth error printed but not fatal), the multi-select was somehow empty, or the manual 'LLMs to add' input was empty/only commas/whitespace.

Common situations: Models fetch failed silently (bad api_base or key) so the fallback manual prompt was given empty input; user pressed Enter without typing models; offline setup against a local server that wasn't running.
