Helper utilities to use Custom Embeddings about langchainjs HOT 3 CLOSED

Thanks for bringing this up as an issue! +1

This would be an extremely valuable contribution to optimize for domain-specific use cases at scale, which is important when you're planning to have a high volume of queries. I would personally use this.

Here's one startup's feedback on why they decided to use custom embeddings: https://www.buildt.ai/blog/viral-ripout

Thanks, @rikuthinks ! Yes, I also highly recommend the Built blog post by @ Pullerz, I had included it in Recommended Reading above along with others I wrote/read -- check them out.

I'm hoping to find some time this or next week to contribute a Pull Request 🤞

Hi, @Glavin001! I'm here to help the LangChain team manage their backlog and I wanted to let you know that we are marking this issue as stale.

From what I understand, you opened this issue to discuss the need for helper utilities to use custom embeddings in a TypeScript application. The proposed solution involves customizing embeddings by multiplying the original embeddings with a custom matrix. It's great to see that rikuthinks and batmanscode have expressed their support for this idea, with rikuthinks mentioning the value of optimizing for domain-specific use cases. You thanked rikuthinks and mentioned your plan to contribute a pull request soon.

Before we mark this issue as stale, we wanted to check with you if this issue is still relevant to the latest version of the LangChain repository. If it is, please let us know by commenting on the issue. Otherwise, feel free to close the issue yourself or it will be automatically closed in 7 days.

Thank you for your contribution and we look forward to hearing from you soon!

Best,
LangChain Team
