    "# Introduction\n",
    "## Goal\n",
    "I have a dataset I want to embed for semantic search (or QA, or RAG), I want the easiest way to do embed this and put it in a new dataset.\n",
    "\n",
    "## Approach\n",
    "Im using a dataset from my favorite subreddit [r/bestofredditorupdates](). Since it has such long entries, I will use the new [jinaai/jina-embeddings-v2-base-en](https://huggingface.co/jinaai/jina-embeddings-v2-base-en) since it has an 8k context length. Since Im GPU-poor I will deploy this using [Inference Endpoint](https://huggingface.co/inference-endpoints) to save money and time. To follow this you will need to add a payment method. To make it even easier, I'll make this fully API based."
