Class Ollama

Class that represents the Ollama language model. It extends the base LLM class and implements the OllamaInput interface.

Example

const ollama = new Ollama({
  baseUrl: "http://api.example.com",
  model: "llama2",
});

// Streaming translation from English to German
const stream = await ollama.stream(
  `Translate "I love programming" into German.`
);

const chunks = [];
for await (const chunk of stream) {
  chunks.push(chunk);
}

console.log(chunks.join(""));
