Unknown AI SDK provider: "${this.providerId}". Supported pro

Error message

Unknown AI SDK provider: "${this.providerId}". Supported providers: ${supportedProviders}. To use a different provider, install the @ai-sdk/* package and add it to the provider map.

What it means

AiSdk looks up the provider prefix of 'provider/model' in PROVIDER_MAP; an unknown providerId means the required @ai-sdk/* package isn't in the map, and initializeProvider throws listing supported options.

Solutions

1. Use one of the providers listed in the error message
2. npm install the matching @ai-sdk/<provider> package and add it to PROVIDER_MAP as the message instructs
3. Fix typos in the provider prefix
4. Check package version for which providers ship in the map

Example fix

// before
new AiSdk({ model: 'mistakelabs/mistral-large' });

// after
new AiSdk({ model: 'mistral/mistral-large' }); // after ensuring @ai-sdk/mistral is in PROVIDER_MAP

const provider = cfg.model.split('/')[0]; if (!PROVIDER_IDS.includes(provider)) throw new Error(`unsupported provider ${provider}`);

function isKnownProvider(model: string, known: readonly string[]): boolean { return known.includes(model.split('/')[0]); }

try { await llm.chatCompletionStream(...) } catch (e) { if (/Unknown AI SDK provider/.test(e.message)) { /* install @ai-sdk pkg and register, or switch model */ } throw e; }

When it happens

Trigger: model like 'foobar/gpt-4o' where 'foobar' isn't a key of PROVIDER_MAP — called lazily on first chatCompletionNonStream/chatCompletionStream/embed.

Common situations: Using a provider whose @ai-sdk/* package isn't installed/registered, typos in the provider prefix, or upgrading removed a provider from the map.
