Custom LLM and AI Agents (RAG) On Structured + Unstructured Data - AI Brain For Your Organization

Ideally, you want to ask a question to an AI bot, and it should be able to run multiple parallel queries on your database, look up relevant information from your docs, collate all the relevant information, and create a coherent response.

As an example - it should be able to respond intelligently to the request - Pull the top 10 customers by usage, closed by the sales rep John Doe, and draft a \"thank you\" email to each of them.

Your AI agent/ Custom LLM must do multiple things to satisfy this request.

- pull all the customers closed by sales rep John Doe from Salesforce
- run a query on Snowflake to get the usage data per customer
- find the thank you email template from your Google Docs folder
- draft emails to all of these customers

Systems that are capable of tasks that are moderately complex, like this one, really improve employee productivity significantly. Organizations that embrace AI in this way will easily outperform their competition.

So here is how you would build this

Data pipelines and connectors - You need connectors to systems like Salesforce, snowflake, and folders.

Chat query orchestrator - you need to be able to parse incoming chat queries, fire multiple calls to an LLM, generate SQL queries, or craft API requests to your vector databases (doc retrievers)

Doc retrievers/vector stores - You must embed and create a vector store for all your shared docs.

Final response creator - A final LLM that will generate the final response based on all the data. In the example above, it would generate the final emails from the email template and the data generated by the SQL queries.

Building these systems from scratch is doable, and there are several open-source libraries you can use to do so. However, the challenge will be iterating on the solution to make sure that the accuracy is high enough to be usable in production.

Several systems have to be tuned, and multiple iterations need to evaluate the system before putting this in production.

Our platform, Abacus AI, can help build, test, and launch a system like this in a matter of days. You can set up the various components quickly and then create multiple iterations and evaluate them across multiple LLMs and configurations.

Finally, you can set up all the pipelines and push the system to production in a matter of days. We offer several open-source fine tunes, which means you won\'t be paying for an expensive LLM if you don\'t have to! ...less

Prompt engineering skills help to better understand the capabilities and limitations of large language models (LLMs). Researchers use prompt engineering to improve the capacity of LLMs on a wide range of common and complex tasks such as question answering and arithmetic reasoning. Developers use prompt engineering to design robust and effective prompting techniques that interface with LLMs and other tools.

Motivated by the high interest in developing with LLMs, we have created this new prompt engineering guide that contains all the latest papers, learning guides, lectures, references, and tools related to prompt engineering for LLMs. ...less

But, what common tricks are used to achieve these efficiency/stability benefits?

TL;DR: Making LLMs more efficient—both during training and inference—boils down to three basic categories of techniques:

1. Modifying the model’s architecture.
2. Modifying the model’s weights.
3. Modifying the training/optimization process.

This post covers several techniques that fall under either of these categories and are commonly used by a variety of recent, state-of-the-art LLMs.

(1) Modifying the architecture. To make an LLM more efficient/stable, we can first try to modify the model’s architecture. Notable examples of this include:

- Flash Attention: a hardware-aware efficient attention implementation that can drastically speed up training (used by numerous LLMs like MPT-7/30B and Falcon).
- Flash Decoding: an extension of flash attention that improves attention efficiency in the inference/decoding stage (in addition to training).
- Multi-Query Attention: an efficient attention implementation that shares key and value vectors between attention heads (used by PaLM and LLaMA-2).

(2) Tweaking the weights. Beyond changing the architecture itself, we can also modify the model’s weights without changing the underlying architecture. More specifically, we can quantize the model’s weights into a lower precision representation, either during training or inference (or both). Example of this include:

- Post-training Quantization: we quantize the LLM’s weights to a lower precision representation prior to inference and perform inference in low precision (commonly used to save costs when hosting/deploying LLMs).
- Low Precision LayerNorm: performs layer normalization in low precision to improve training efficiency without impacting model quality (used by MPT-7/30B).
- Quantized training: we quantize the LLM’s weights throughout the entire training process to yield a speedup. The most common example of this is Automatic Mixed Precision (AMP) training, which is widely used in deep learning.

(3) Changing the optimization process. Finally, we can also explore changes to the model’s underlying optimization process. Typically, these changes are a bit difficult to explore—training LLMs is incredibly expensive and we don’t want to pay for training runs that yield poor results. Nonetheless, several interesting techniques have been explored:

- Lion Optimizer: a new adaptive optimizer (i.e., this would replace another optimizer like AdamW) that has been shown (by LLMs like MPT-7B) to improve the stability of LLM training.
- Adaptive Sequence Length: models like MPT-7/30B and Orca have shown us that we can speed up the LLM training process by first training on shorter / less complex examples, then training over longer / more complex examples.
- LoRA: parameter efficient finetuning techniques like LoRA, LLaMA Adapter, and many more achieve impressive results by training efficient, low-rank parameterizations of LLMs. Arguably, these approaches modify more than just the optimization process (i.e., the model is changed as well), but they are nonetheless incredibly effective. ...less

(i) Query expansion using an LLM to rewrite and improve a query, by either generating either additional relevant queries or a hypothetical answer to the query.
(ii) Reranking using a cross-encoder - a model trained to measure similarity between two inputs presented simultaneously. Reranking reorders retrieved documents based on the cross-encoder similarity measure.
(iii) Constructing and training an Embedding Adaptor, which is a model that adapts the embedding values to be more relevant to your use case.
Each of these techniques can help you build much better RAG systems. ...less
