Quiz and Answer Key

Explain the core functionality of a Foundation Model and provide a key characteristic that distinguishes this type of LLM.

A Foundation Model is an LLM designed to generate and understand human-like text across a wide range of use-cases. A key characteristic is its broad pre-training on massive datasets, enabling it to perform diverse tasks with minimal or no task-specific fine-tuning.

Describe the process of Fine-Tuning an LLM. What is the primary goal of this process?

Fine-tuning is the process of adapting a pre-trained LLM to a specific task or domain by further training it on task-specific data. The primary goal is to improve the LLM’s performance and accuracy on the targeted application.

What is Retrieval-Augmented Generation (RAG)? Briefly outline the roles of the Knowledge Base and Vector Database in this process.

Retrieval-Augmented Generation (RAG) is a framework that enhances LLM responses by retrieving relevant information from an external Knowledge Base and appending it to the prompt. The Knowledge Base is a collection of documents, while the Vector Database stores vector representations of this KB to enable efficient similarity-based retrieval.

Differentiate between Zero-Shot Learning and Few-Shot Learning in the context of prompting LLMs for specific tasks.

In Zero-Shot Learning, an LLM is given only task instructions and must rely solely on its pre-existing knowledge to perform the task. In contrast, Few-Shot Learning provides the LLM with a very small number of examples alongside the task instructions to guide its output generation.

Define Instruction Tuning and explain how it aims to improve the behavior of an LLM.

Instruction Tuning involves adjusting an LLM’s behavior during fine-tuning by providing specific instructions along with the training data. This process aims to improve the LLM’s ability to follow instructions and generate more accurate and relevant responses based on those instructions.

What is Hallucination in the context of LLMs? Provide a brief example of what this might look like.

Hallucination in LLMs refers to the tendency of these models to sometimes generate incorrect, nonsensical, or factually inconsistent information that is not grounded in the provided context or their training data. An example could be an LLM generating a fictitious historical event or attributing a quote to the wrong person.

Explain the concept of Context Length and why it is a significant factor in LLM performance.

Context Length is the maximum number of input words or tokens that an LLM can consider when generating an output. It is significant because it limits the amount of information the LLM can process at once, impacting its ability to understand long documents or maintain context over extended conversations.

Describe In-Context Learning and how it differs from traditional fine-tuning methods.

In-Context Learning involves integrating task examples directly into the prompts provided to an LLM, enabling it to understand and handle new tasks without requiring explicit fine-tuning of its weights. This approach leverages the LLM’s pre-existing knowledge and its ability to learn from the provided examples within the prompt itself.

What is Reinforcement Learning from Human Feedback (RLHF)? Briefly explain the role of Reward Modeling in this process.

Reinforcement Learning from Human Feedback (RLHF) is a technique that uses human feedback as a reward or penalty signal to further train an LLM and align its behavior with human preferences. Reward Modeling is a key component where a separate model is trained to predict the human preference score for different LLM outputs, which then serves as the reward signal during reinforcement learning.

Explain the concept of Prompt Injection and why it is considered a security vulnerability for LLMs.

Prompt Injection refers to deliberate attempts to trick LLMs with carefully crafted inputs that manipulate the model’s original instructions and cause it to perform unintended or malicious tasks. This is a vulnerability because it can be exploited to bypass safety measures, extract sensitive information, or generate harmful content.

LLM 1YesYes2048 tokens
LLM 2NoYes4096 tokens
LLM 3YesNo1024 tokens

For instance, Here, we could choose LLM 2 if we don’t care about fine-tuning and focus more on having a larger context window.

2. How Accurate Is It?

Accuracy is key. If you want an LLM that can give you reliable answers, test it with some real-world data to see how well it performs. Here are some questions:

  • Can the LLM be improved with tuning?
  • Does it consistently perform well?

Accuracy Comparison

LLMGeneral AccuracyAccuracy with Custom Data
LLM 190%85%
LLM 285%80%
LLM 388%86%

Here, we could choose LLM 3 if we prioritize accuracy with custom data, even if its general accuracy is slightly lower than LLM 1.

3. What Does It Cost?

LLMs can get expensive, especially when they’re in production. Some charge per use (like ChatGPT), while others have upfront costs for setup. Here are some questions:

  • Is the cost a one-time fee or ongoing (like a subscription)?
  • Is the cost worth the business benefits?

Cost Comparison

LLMCostPricing Model
LLM 1HighPay per API call (tokens)
LLM 2LowOne-time hardware cost
LLM 3MediumSubscription-based

If minimizing ongoing costs is a priority, LLM 2 could be the best choice with its one-time hardware cost, even though LLM 1 may offer more flexibility with pay-per-use pricing.

4. Is It Compatible with Your Tech?

Make sure the LLM fits with your current tech setup. Most LLMs use Python, but your business might use something different, like Java or Node.js. Here are some questions:

  • Does it work with your existing technology stack?

LLM 2Medium (Moderate)Limited
LLM 3High (Difficult)Inadequate

For instance: If ease of maintenance is a priority, LLM 1 would be the best choice, given its low maintenance needs and excellent documentation, even if other models may offer more features.

6. How Fast Is It? (Latency)

Latency is the time it takes an LLM to respond. Speed is important for some applications (like customer service), while for others, it might not be a big deal. Here are some questions:

  • How quickly does the LLM respond?

Latency Comparison

LLMResponse TimeCan It Be Optimized?
LLM 1100msYes (80ms)
LLM 2300msYes (250ms)
LLM 3200msYes (150ms)

For instance, If response speed is critical, such as for customer service applications, LLM 1 would be the best option with its low latency and potential for further optimization.

7. Can It Scale?

If your business is small, scaling might not be an issue. But if you’re expecting a lot of users, the LLM needs to handle multiple people or lots of data simultaneously. Here are some questions:

  • Can it scale up to handle more users or data?

Scalability Comparison

LLMMax UsersScalability Level
LLM 11000High
LLM 2500Medium
LLM 31000High

If scalability is a key factor and you anticipate a high number of users, both LLM 1 and LLM 3 would be suitable choices. Both offer high scalability to support up to 1000 users.

8. Infrastructure Needs

Different LLMs have varying infrastructure needs—some are optimized for the cloud, while others require powerful hardware like GPUs. Consider whether your business has the right setup for both development and production. Here are some questions:

  • Does it run efficiently on single or multiple GPUs/CPUs?
  • Does it support quantization for deployment on lower resources?
  • Can it be deployed on-premise or only in the cloud?

For instance, If your business lacks high-end hardware, a cloud-optimized LLM might be the best choice, whereas an on-premise solution would suit companies with existing GPU infrastructure.

9. Is It Secure?

Security is important, especially if you’re handling sensitive information. Make sure the LLM is secure and follows data protection laws.

  • Does it have secure data storage?
  • Is it compliant with regulations like GDPR?

Security Comparison

ChatRWKV’s tailored feature is its capacity to produce excellent responses, especially true with the RWKV-6 version, which has proven to be a highly effective tool.

On top of that, the presence of RWKV Discord, a community with over 7,000 members, suggests that this technology has a healthy following, because of its open-source nature and cutting-edge resources available, making it a fantastic choice for developers and researchers interested in experiencing RNN-based language models for chatbots.

11. Cerebras-GPT

The Cerebras-GPT is a family of large language models (LLMs) developed by Cerebras Systems to aid in studying LLM scaling laws using open architectures and datasets.

Having been trained using Chinchilla scaling principles and including parameters ranging from 111M to 13B, these models are compute-optimal. On top of that, these models may be found on Hugging Face, and EleutherAI’s Pile dataset as used in their training.

Even though chatbot functionality isn’t addressed specifically, Cerebras-GPT models are meant to show off how easy and scalable it is to train LLMs using the Cerebras hardware and software stack. This implies that research and development should take precedence over using chatbots in the real world.

12. Open Assistant

OpenAssistant is a finished project that aims to make a high-quality chat-based large language model accessible. The project aims to elevate language itself, revolutionizing language innovation and making the world a better place.

This tool’s inclusive features include a chat frontend for real-time communication and a data gathering frontend for enhancing the assistant’s functionality, which OpenAssistant provides.

The release of the OpenAssistant Conversations (OASST1) corpus, highlights the democratization of large-scale alignment research. Moreover, HuggingFace hosts the final published oasst2 dataset at OpenAssistant/oasst2.

OpenAssistant’s models and code are available under the Apache 2.0 license as an open-source project, which permits a variety of usage, including for profit. The initiative is designed and managed by LAION, which includes a team of volunteers across the globe.

The project offers chances for participation in data collection and development for any individuals interested in contributing.

Conclusion

With the help of these cutting-edge resources, small businesses, researchers, and developers can take advantage of language-based technology and take on the biggest names in the market.

Even though they may not outperform GPT-4, it is clear that they have room to grow and improve with the help of the community. These models are particularly perfect substitutes for GPT-4.

What are Small Language Models (SLMs)?

Introduction

Everyone’s talking about Large Language Models, or LLMs, and how amazing they are. But there’s also something exciting happening with Small Language Models (SLMs) that are starting to get more attention. Big advancements in the field of NLP come from powerful or “Large” models like GPT-4 and Gemini, which are experts in handling tasks such as translating languages, summarizing text, and having conversations. These models are great because they process language much like humans do. 

But, there’s a catch with these big models: they need a lot of compute power and storage, which can be expensive and hard to manage, especially in places where there’s not a lot of advanced technology.

To fix this problem, experts have come up with Small Language Models or SLMs. These smaller models don’t use as much compute and are easier to handle, making them perfect for places with less tech resources. Even though they’re smaller, they’re still powerful and can do many of the same jobs as the bigger models. So, they’re small in size but big in what they can do.

What are Small Language Models?

Small language models are simple and efficient types of neural networks made for handling language tasks. They work almost as well as bigger models but use far fewer resources and need less computing power. 

Imagine a language model as a student learning a new language. A small language model is like a student with a smaller notebook to write down vocabulary and grammar rules. They can still learn and use the language, but they might not be able to remember as many complex concepts or nuances as a student with a larger notebook (a larger language model).

The advantage of SLMs is that they are faster and require less computing power than their larger counterparts. This makes them more practical to use in applications where resources are limited, such as on mobile devices or in real-time systems.

However, the trade-off is that SMLs may not perform as well as larger models on more complex language tasks, such as understanding context, answering complicated questions, or generating highly coherent and nuanced text.

What is “Small” in Small Language Models?

The term “small” in small language models refers to the reduced number of parameters and the overall size of the model compared to large language models. While LLMs can have billions or even trillions of parameters, SLMs typically have a few million to a few hundred million parameters(in a few cases up to a couple of billions as well).

The number of parameters in a language model determines its capacity to learn and store information during training. More parameters generally allow a model to capture more complex patterns and nuances in the training data, leading to better performance on natural language tasks.

However, the exact definition of “small” can vary depending on the context and the current state of the art in language modeling. As model sizes have grown exponentially in recent years, what was once considered a large model might now be regarded as small.

Examples of Small Language Models

Some examples of small language models include:

  • GPT-2 Small: OpenAI’s GPT-2 Small model has 117 million parameters, which is considered small compared to its larger counterparts, such as GPT-2 Medium (345 million parameters) and GPT-2 Large (774 million parameters). Click here.
  • DistilBERT: This is a distilled version of BERT (Bidirectional Encoder Representations from Transformers) that retains 95% of BERT’s performance while being 40% smaller and 60% faster. DistilBERT has around 66 million parameters. Click here.
  • TinyBERT: Another compressed version of BERT, TinyBERT is even smaller than DistilBERT, with around 15 million parameters. Click here.

While SLMs typically have a few hundred million parameters,  some larger models with 1-3 billion parameters can also be classified as SLMs because they can still be run on standard GPU hardware. Here are some of the examples of such models:

  • Phi3 Mini: Phi-3-mini is a compact language model with 3.8 billion parameters, trained on a vast dataset of 3.3 trillion tokens. Despite its smaller size, it competes with larger models like Mixtral 8x7B and GPT-3.5, achieving notable scores of 69% on MMLU and 8.38 on MT-bench. Click here.
  • Google Gemma 2B: Google Gemma 2B is a part of the Gemma family, lightweight open models designed for various text generation tasks. With a context length of 8192 tokens, Gemma models are suitable for deployment in resource-limited environments like laptops, desktops, or cloud infrastructures. Click here.
  • Databricks Dolly 3B: Databricks’ dolly-v2-3b is a commercial-grade instruction-following large language model trained on the Databricks platform. Derived from pythia-2.8b, it’s trained on around 15k instruction/response pairs covering various domains. While not state-of-the-art, it exhibits surprisingly high-quality instruction-following behavior. Click here.

How do Small Language Models Work?

Small language models use the same basic ideas as large language models, like self-attention mechanisms and transformer structures. However, they use different methods to make the model smaller and require less computing power:

  • Model Compression: SLMs use methods like pruning, quantization, and low-rank factorization to cut down the number of parameters. This means they simplify the model without losing much performance.
  • Knowledge Distillation: In this technique, a smaller model learns to act like a larger, already trained model. The student model tries to produce results similar to the teacher, effectively squeezing the essential knowledge from the big model into a smaller one.
  • Efficient Architectures: SLMs often use specially designed structures that focus on being efficient, such as Transformer-XL and Linformer. These designs modify the usual transformer structure to be less complex and use less memory.

Differences Between Small Language Models (SLMs) and Large Language Models (LLMs):

CriteriaSmall Language Models (SLMs)Large Language Models (LLMs)
Number of ParametersFew million to a few hundred millionBillions of parameters
Computational RequirementsLower, suitable for resource-constrained devicesHigher, require substantial computational resources
Ease of DeploymentEasier to deploy on resource-constrained devicesChallenging to deploy due to high resource requirements
Training and Inference SpeedFaster, more efficientSlower, more computationally intensive
PerformanceCompetitive, but may not match state-of-the-art results on certain tasksState-of-the-art performance on various NLP tasks
Model SizeSignificantly smaller, typically 40% to 60% smaller than LLMsLarge, requiring substantial storage space
Real-world ApplicationsSuitable for applications with limited computational resourcesPrimarily used in resource-rich environments, such as cloud services and high-performance computing systems

Pros and Cons of SLMs:

Here are some pros and cons of Small Language Models:

Pros:

  • Computationally efficient, requiring fewer resources for training and inference
  • Easier to deploy on resource-constrained devices like mobile phones and edge devices
  • Faster training and inference times compared to LLMs
  • Smaller model size, making them more storage-friendly
  • Enable wider adoption of NLP technologies in real-world applications

Cons:

  • May not achieve the same level of performance as LLMs on certain complex NLP tasks
  • Require additional techniques like model compression and knowledge distillation, which can add complexity to the development process
  • May have limitations in capturing long-range dependencies and handling highly context-dependent tasks
  • The trade-off between model size and performance needs to be carefully considered for each specific use case
  • May require more extensive fine-tuning or domain adaptation compared to LLMs to achieve optimal performance on specific tasks

Despite these limitations, SMLs offer a promising approach to making NLP more accessible and efficient, enabling a wider range of applications and use cases in resource-constrained environments.

Conclusion

Small Language Models are a good alternative and adding to Large Language Models because they are efficient, less expensive, and easier to manage. They can do many different language tasks and are becoming more popular in artificial intelligence and machine learning.

Before you decide to use a Large Language Model for your project, take a moment to think about whether a Small Language Model could work just as well. This is like in the past when people used to pick complex Deep Learning models, even though simpler machine learning models could have done the job too—and that’s still something to consider today.

Local Nomic Embed: Run OpenAI Quality Text Embeddings Locally.

On February 1st, 2024, Nomic AI released Nomic Embed – a truly open, auditable, and highly performant text embedding model. Since this release, we’ve been excited to see this model adopted by our customers, inference providers and top ML organizations – trillions of tokens per day run through Nomic Embed.

At Nomic we understand that engineering teams value flexibility and optionality in their machine learning stack.

We’re excited to introduce an officially supported fully local version of Nomic Embed that exactly matches our remote inference API powered by GPT4All local inference. Just specify inference_mode=’local’ and you are set.

pip install nomic
from nomic import embed
import numpy as np

output = embed.text(
    texts=[
        'Nomic Embed now supports local and dynamic inference to save you inference latency and cost!',
        'Hey Nomic, why don\'t you release a multimodal model soon?',
    ],
    model='nomic-embed-text-v1.5',
    task_type="search_document",
    inference_mode='local',
    dimensionality=768,
)

print(output['usage'])

embeddings = np.array(output['embeddings'])

print(embeddings.shape)

Dynamic Inference Mode: Remote and Local

Nomic Embed dynamic inference switches between the local model instance and a remote API based on statistics of your input text.

This allows for small inputs to run on your local machine (e.g. MacBook, EC2 instance) and larger queries to dynamically route to the remotely hosted Nomic Embedding API.

This new capability allows engineers to walk the Pareto frontier of embedding latency and cost. For short text inputs, the network round trip (100-200ms) to a hosted API is slower than running inference locally – in this case, dynamic mode will just run the inference locally and free of charge.

For queries with a long sequence length or large batch size, remote inference is faster so dynamic inference will route queries to the Nomic Embedding API.

How does local and dynamic inference mode work?

Local inference works by running on a ggml graph of Nomic Embed via GPT4All. When you request local inference, the model will automatically download to your machine and be used for embed.text requests.

Dynamic mode switches between local and remote API mode with the objective of saving inference latency and cost. For example, on a 2023 MacBook Pro (16GB), local mode is faster than remote inference (assuming 200ms network latency) for up to 1024 token length inputs.

What software, models and hardware are supported?

Currently only the Nomic python bindings to the Nomic Embedding API support local mode.

All current Nomic Embed models including nomic-embed-text-v1 and nomic-embed-text-v1.5 with binary, resizable embeddings are supported.

Local inference mode supports any CPU or GPU that GPT4All supports, including Apple Silicon (Metal), NVIDIA GPUs, and discrete AMD GPUs.

How fast is local mode?

We benchmark Nomic Embed in local inference mode across a variety of CPUs and GPUs with a batch size of one. It’s usually preferable to use remote mode with batch sizes larger than one. The below chart is constructed by sampling inference latency on a variety of target hardware devices supported by GPT4All.

Local Nomic Embed Benchmarking

In general, you should prefer to use Nomic Embed local mode in any configuration below the Nomic API curve. Dynamic inference mode will automatically detect these cases and switch to the local model.

Note that local inference latency on Mac Metal is quite competitive at long sequence lengths.

Can I use local mode with LangChain or LlamaIndex?

When using the LangChain or LlamaIndex integrations, the inference_mode and device parameters work the same as with embed.text. For LangChain:

from langchain_nomic import NomicEmbeddings

embeddings = NomicEmbeddings(
    model='nomic-embed-text-v1.5',
    inference_mode='local',
    device='gpu',
)

result = embeddings.embed_documents(['text to embed'])

For LlamaIndex:

from llama_index.embeddings.nomic import NomicEmbedding

embed_model = NomicEmbedding(
    model_name='nomic-embed-text-v1.5',
    inference_mode='local',
    device='gpu',
)

result = embed_model.get_text_embedding('text to embed')
