Invalid model format

Error message

Invalid model format

What it means

parseProxyModelName splits the model string on '/'; it requires at least owner/package/provider/model structure. If provider or model is empty (fewer than 4 meaningful segments), the format is invalid.

Source

Solutions

1. Use the full format: owner/package/provider/model, e.g. my-owner/my-package/openai/gpt-4o
2. If you only have provider/model, add the correct owner and package slugs
3. Validate the segment count before calling

Example fix

// before
parseProxyModelName('openai/gpt-4');
// after
parseProxyModelName('my-owner/my-package/openai/gpt-4');

function isProxyModelName(s: string): boolean {
  const parts = s.split('/');
  return parts.filter(Boolean).length >= 4;
}

try { parseProxyModelName(m); } catch (e) { if (e.message === 'Invalid model format') { /* prompt for owner/package/provider/model */ } }

When it happens

Trigger: parseProxyModelName('gpt-4'), parseProxyModelName('openai/gpt-4'), or any string with fewer than 4 slash-separated parts; also a trailing slash making model empty.

Common situations: Passing a plain model name where the proxy format (owner/package/provider/model) is expected, or omitting the owner/package prefix.
