No valid models

Error message

No valid models

What it means

fetch_models calls the provider's {api_base}/models endpoint and extracts the 'id' fields from the 'data' array of the JSON response. If the extracted list is empty — because the response has no 'data' array, wrong shape, or zero entries — it throws 'No valid models'.

Solutions

1. Verify api_base points to an OpenAI-compatible endpoint exposing GET /models
2. Check that the API key is valid and has access to at least one model; test with curl -H "Authorization: Bearer $KEY" {api_base}/models
3. Inspect the raw JSON response shape and confirm it contains data[].id strings
4. Point at a different deployment/provider that actually serves models

Example fix

// before
let models = fetch_models("https://wrong-host.example/v1", Some("sk-bad"))?;
// after
let models = fetch_models("https://api.openai.com/v1", Some("sk-correct"))?;

// preflight: call /models yourself and check shape
let v: serde_json::Value = client.get(format!("{base}/models")).send().await?.json().await?;
let ok = v.get("data").and_then(|d| d.as_array()).map(|a| !a.is_empty()).unwrap_or(false);
if !ok { /* fix api_base/api_key before calling fetch_models */ }

fn has_models(v: &serde_json::Value) -> bool {
    v.get("data").and_then(|d| d.as_array())
     .map(|a| a.iter().any(|m| m.get("id").and_then(|i| i.as_str()).is_some()))
     .unwrap_or(false)
}

match fetch_models(api_base, api_key).await {
    Ok(models) if !models.is_empty() => models,
    Ok(_) => anyhow::bail!("provider returned empty model list; check api_base/key"),
    Err(e) => return Err(e),
}

When it happens

Trigger: Calling fetch_models when the /models response contains no data array of objects with string 'id' fields, or the array is empty.

Common situations: Wrong api_base pointing to a non-OpenAI-compatible server; missing/invalid API key so the server returns an error object instead of a model list; provider version change that renamed the response field; self-hosted gateway that returns an empty model list.

Understand the failure class

Background: EmptyResultError / "no results found": when an API or scraper succeeds but returns zero rows — this error's family across 9 libraries.
