+## Access to Refuel hosted LLMs
+
+Refuel provides access to hosted open source LLMs for labeling, and for estimating confidence This is helpful, because you can calibrate a confidence threshold for your labeling task, and then route less confident labels to humans, while you still get the benefits of auto-labeling for the confident examples.
+
+In order to use Refuel hosted LLMs, you can [request access here](https://refuel-ai.typeform.com/llm-access).

+## Benchmark
+
+Check out our [technical report](https://www.refuel.ai/blog-posts/llm-labeling-technical-report) to learn more about the performance of various LLMs, and human annoators, on label quality, turnaround time and cost.
+
 ## 🛠️ Roadmap
 Our goal is to allow users to label, create or enrich any dataset, with any LLM - easily and quickly.

+## Benchmarking LLMs for data labeling
+
+
+Key takeaways from our [technical report](https://www.refuel.ai/blog-posts/llm-labeling-technical-report):
+
+* State of the art LLMs can label text datasets at the same or better quality compared to skilled human annotators, **but ~20x faster and ~7x cheaper**.
+* For achieving the highest quality labels, GPT-4 is the best choice among out of the box LLMs (88.4% agreement with ground truth, compared to 86% for skilled human annotators). 
+* For achieving the best tradeoff between label quality and cost, GPT-3.5-turbo, PaLM-2 and open source models like FLAN-T5-XXL are compelling.
+* Confidence based thresholding can be a very effective way to mitigate impact of hallucinations and ensure high label quality.
