Example Code

const OPENAI_API_BASE = 'https://api.deepseek.com/v1';
const OPENAI_API_EMBEDDING_MODEL = "deepseek-reasoner";

async function saveToDb(db) {
  const directory = path.resolve(__dirname, `../dbc/`);
  db.map(async (item) => {
    const docs = item.docs.examples?.map(
      (item) =>
        new Document({
          pageContent: item.description,
          metadata: {
            source: item.source,

Hey @liuseen-l! I'm here to help you with any bugs, questions, or contributions you have. Let's tackle this together!

The "MODEL_NOT_FOUND" error you're encountering with the "deepseek-reasoner" model indicates that the model name is not recognized by the LangChain framework. This could be due to an incorrect model name or the model not being supported by LangChain.

To resolve this issue, ensure that the model name is correct and matches one of the supported model names in LangChain. The supported model names include:

• bedrock
• ibm
• llama_cpp
• tencent_hunyuan
• webllm
• zhipuai
• gradient_ai
• hf
• ollama
• raycast
• replicate
• sagemaker_endpoint
• togetherai
• watsonx_ai
• writer
• yandex
• layerup_security

Unfortunately, "deepseek-reasoner" is not listed among the supported models ^[1][2]. You may need to choose a different model that is supported by LangChain.
