Made With ML

Excited to share our end-to-end LLM workflows guide that we’ve used to help our industry customers fine-tune and serve OSS LLMs that outperform closed-source models in quality, performance and cost. anyscale.com/blog/end-to-en… 1/🧵

@rauchg Glad you're finding it useful! Check out our accompanying blog post and the evaluation experiments we ran comparing across a suite of open-source and proprietary LLMs: anyscale.com/blog/anyscale-…

Very impressed with @anyscalecompute's endpoints, which support tools / function calling. 2LOC to play with Mixtral as a replacement for GPT 🤯

It's been nice to see small jumps in output quality in our RAG applications from chunking experiments, contextual preprocessing, prompt engineering, fine-tuned embeddings, lexical search, reranking, etc. but we just added Mixtral-8x7B-Instruct to the mix and we're seeing a 🤯 step-function improvement (even compared to gpt-4-0613, see eval reports below)! 🤔 @pcmoritz and I are curious if others are seeing quality jumps like this in their applications and any ideas as to why (MoE, training cutoffs, etc.)? - 📜 Blog: anyscale.com/blog/a-compreh… - 💻 Code: github.com/ray-project/ll… - 📓 Notebook: github.com/ray-project/ll… - 🚀 Endpoints: docs.endpoints.anyscale.com (Mixtral at $0.5 / million tokens on @anyscalecompute)

One of the most common asks we get is for public (and reproducible) performance benchmarks. LLM inference performance benchmarks are subtle, and this is a rapidly evolving space, so numbers quickly become stale. But to make comparisons, we need to be talking about the same thing. So today, we are open sourcing our benchmark suite. We invite the community to run it and to collaborate with us on augmenting it. 🎉🎉 github.com/ray-project/ll… Alright, so what metrics are we measuring 🤔 The following are fundamental metrics. In general we are interested not just in the mean but in the distribution (P50, P90, ...) 📊 ⚫️ Time to first token: The time before the LLM returns the first token. This matters for streaming applications, especially chatbots. ⚫️ Inter-token latency: The average time between consecutive tokens. We choose to include the time to first token in this measurement to avoid the degenerate case where some systems start streaming very late. ⚫️ End-to-end latency: The time from submitting the query to receiving the full response. ⚫️ Cost (e.g., per token): API providers can often trade off one of the other metrics for cost. For example, you can reduce latency by running the same model on more GPUs or using higher-end GPUs. When running models yourself on dedicated compute, replace cost with throughput (tokens / second). Interestingly, these metrics can be traded off against each other. Some considerations when doing so 👇 1⃣ A given model (e.g., Code Llama 34B) can be deployed in many ways on the same hardware (say a p4de instance). E.g., N replicas each with 8/N GPUs. 2⃣ Pipeline parallelism can improve throughput at the expense of latency. 3⃣ Time to first token is bottlenecked by compute whereas intertoken latency is bottlenecked by GPU memory bandwidth. This is just the start. We hope to work with other LLM providers to increase the level of rigor around benchmarking and provide some consistency around the metrics that we report.

The definitive guide to RAG in production! 🙏 @GokuMohandas walks us through implementing RAG from scratch, building a scalable app It now has updated discussion on embedding fine-tuning, re-ranking and effectively routing requests I think this is easily the most complete discussion on building RAG Apps A perfect weekend read to code along: anyscale.com/blog/a-compreh…

We updated our production RAG application guide with a number of new sections: ☑️ When to fine-tune embeddings ☑️ When to augment vector-based retrieval with traditional lexical search ☑️ When to rerank retrieved context ☑️ How to update & reindex as data changes Importantly, building a RAG application is not a one-time effort. Data constantly evolves (for example, if you build a Q&A chatbot for your documentation, you have to remember that your documentation and APIs are changing underneath you). As a consequence, you have to make sure that data is reindexed and that the application continues to work. We describe our process in the guide.

Added some new components (fine-tuning embeddings, lexical search, reranking, etc.) to our production guide for building RAG-based LLM applications. Combination of these yielded significant retrieval and quality score boosts (evals included). Blog: anyscale.com/blog/a-compreh…

I burned in🔥2000$ in finetuning so you don't have to. I fine-tuned models with @OpenAI and @anyscalecompute API endpoints with 50million tokens. Here are the results I wish I knew before getting into finetuning. If you just want a quick snapshot, look at the figure. A longer explanation follows, explaining my findings. I am not an expert and not deep into theory of AI models. I just want to get the BEST model performance at the CHEAPEST possible price for my USE-CASE. And quickly deploy that to prod. I picked one specific simple USE-CASE. Summarizing text in a very specific tone, voice and a very specific structure. Trained both models with close to 50M tokens (~37M words). In short, - Anyscale costs 40X cheaper to finetune. - Anyscale costs 56x cheaper to finetune. Comparing the outputs, I get on par performance from llama-13b-fine-tuned as gpt-3.5-fine-tuned. Finetuning smaller models is clearly the way to go for simpler use-cases! I don't understand OpenAI's offering for fine-tuning here. They need to step-up the game. They need to either reduce the price or offer flexibility to compete with open-source fine-tuning models. I am going to run an another experiment which is a way more complicated use-case. It would be interesting to see who wins here. I suspect @OpenAI Turbo will have an edge here (otherwise the pricing does not make sense). P.S : I also know I can finetune models locally & directly without API. Like I said, I am not deep into theory yet. I tried this in @huggingface with their auto-train framework. But it was just not as easy as plugging in via API calls. There were adapters and stuff, and I got quickly lost. But I am reading up and will try start including them in the comparisons too. If anyone is aware of other managed/otherwise solutions for finetuning let me know please.

Anyscale Endpoints enables AI application developers to easily swap closed models for the Llama 2 models — or use open models along with closed models in the same application.

The team @MetaAI has done a tremendous amount to move the field forward with the Llama models. We're thrilled to collaborate to help grow the Llama ecosystem. anyscale.com/blog/anyscale-…
