WTF is this about

🤖 Large Language Models (LLMs) are going be here for minute
- “AI vs. LLM, these are exactly the same”
- LLMs are a type of Generative AI (GenAI)
Open-weight (vs. proprietary) models allow us at RVAsec to more easily…
- 🔒 Maintain data privacy
- 🔩 Tinker and build your own solutions

I’m a data scientist with some cybersecurity experience

We’ll focus on demonstrating their use and highlight some risks

This image is a screenshot of a user review from an online platform, likely a movie review website.

The review is titled “I couldn’t decide whether to give this movie a 1 or a 10.”

The reviewer, identified as “amykatherine”, expresses a unique and somewhat contradictory opinion about the movie.

They describe the movie as both terrible and fantastic, stating that it has everything, including an actor who uses exaggerated facial expressions to convey emotion, unnecessary nudity, and illogical death scenes.

Despite these criticisms, the reviewer also praises the script and the actor’s performance, calling the movie one of their favorites.

The review is dated July 5, 2003, and has received 87 helpful votes.

Large Language Models 🤖

…and the basics to get hacking! 📟

First, LLMs are just software 💻

input -> program -> output

Don’t get lost in the hype

AutoRegressive Causal Language Models

Each blue (input) and orange dot (output) are a token in this animation.
Output at one time step becomes input on next time step
Train a neural network to essentially “fill-in-the-blank” on internet-scale text data

What’s a token?

🔵 inputs are integer indices into a lookup table 📒 in the LLM
- The table contains a vector of real values representing the token
Thus, each token is converted to a bunch of numbers
- These vectors and all the model weights are learned during training

More tokens (input or output) means more processing

Tokenizing and using a sentence

Quicky peak at how “Good afternoon RVAsec14!” get’s processed

1-Text to sub-words
2-Convert Subwords to Token IDs
3 - Tokenizing for generation

from transformers import AutoModelForCausalLM, AutoTokenizer
checkpoint = "HuggingFaceTB/SmolLM-135M-Instruct"
tokenizer = AutoTokenizer.from_pretrained(checkpoint)

# Load a pre-trained tokenizer (e.g., BERT)
# - this will download the model to HF_HUB_CACHE env var
txt = "Good afternoon RVAsec14"

# The string representation of the subword tokens that bert uses
tokens = tokenizer.tokenize(txt)
tokens

['Good', 'Ġafternoon', 'ĠR', 'VA', 'sec', '1', '4']

# The IDs (integers) corresponding to subword tokens
token_ids = tokenizer.convert_tokens_to_ids(tokens)
token_ids

[14229, 11342, 428, 17103, 5016, 33, 36]

model = AutoModelForCausalLM.from_pretrained(checkpoint)
inputs = tokenizer(txt, return_tensors="pt")
model_output = model.generate(**inputs)
tokenizer.decode(model_output[0])

'Good afternoon RVAsec14.\n\nRVAsec14:\n\n```\nRVAsec14:\n\n```\n\nRVAsec14:\n\n```\nRVAsec14:'

What dataset?

Train on “TinyStories” dataset 📜
- Basically short stories for children 👶
- Enables researchers to study language models with less 💵

Track your training like a data scientist

mlflow ui

Load the model and generate text

from transformers import pipeline
story_pipeline = pipeline('text-generation', model=demo_path)
prompt = """Once upon a time"""
completed_story = story_pipeline(prompt)
print(completed_story)

Once upon a time there was a little girl who was three years old.

She loved to play outside and explore all the animals.

LLMs don’t remember previous executions

There is no “memory” or “state”

prompt = """A rabbit in the woods"""
completed_story = story_pipeline(prompt)
print(completed_story)

A rabbit in the woods replied, “That’s a good idea”.

Tom opened his wide eyes wide and saw little rabbit hopping around the forest.

He said, “Hey! What are you doing?”

Pretraining: Creates a completion model (or “base model”)
- 💡 Idea is to build a general-purpose model, not task specific
- Usually semi-supervised training, reducing need for labeled data
  - Usually a large model on lot’s of data for a while
Fine-tuning: Small task-specific update after pretraining
- Think typical machine learning and modeling, but training starts from pretrained model
  - Usually supervised training, sometimes called “aligning”
- instructtion-tuned are chat-like models

So where do we get these “weights”?

Once upon a time, there was a lonely monkey living in a jungle. Every day, he would hop from tree to tree in search of a friend, but never did he find one. He felt so alone.
One day, as he was swinging from a vine, a monkey revealed himself from behind a bush. He said, “Hi! I’m Bob. What’s your name?” The lonely monkey was so happy. “My name is Tim!”, he said with a smile.

These “Trojans” may lurk in the pretrained models

Enable attacker to compromise model, force errors, or leak data when instructed Vassilev et al. (2024)

Persistent Pre-Training Poisoning of LLMs

Learning to Poison Large Language Models During Instruction Tuning

Remember: Information is “stored” in the context and the weights

Context: The provided information, e.g., “Once upon a time”
Weights: The training information and how to combine it with a context

LLM weights are expensive to pretrain

Focus on the context when using LLMs

… but know the source of your pretrained weights 🇨🇳

So what do we do with all this “context”?

I'm sorry, but as an language model AI, I don't have access to real-time information about the current weather. However, you can easily check the weather in your location by searching for "weather" followed by your city or zip code on any search engine or using a weather forecasting app.

  # User message

Today's weather in Richmond, Virginia, is sunny with a temperature of 78 degrees Fahrenheit and a light breeze coming from the west.

What’s in `get_weather()`?

def get_weather() -> str:
  return "Sunny, 78 degrees fahrenheit, light breeze from the west"

get_weather() is a trivial example of retrieving data to augment the LLM’s generation

I.e., this would actually be a call to a weather API

Using the guidance Python library, an interface to llguidance

What’s `guidance`?

Example From their GitHub README

from guidance import substring

# define a set of possible statements
text = 'guidance is awesome. guidance is so great.'
text += 'guidance is the best thing since sliced bread.'

# force the model to make an exact quote
print(g

This email is likely spam

How should we search wikipedia?

Basic steps for a 2-phase search of Wikipedia

Given user string query
- “What’s the population of Richmond Virginia?”
Phase I
1. Expand topics based on the query
2. Search all information sources for topics
3. Assess relevance of those sources
Phase II
1. Retrieve full content of most relevant sources
2. Prompt for answer given relevant source’s content and user query

First, we expand topics based on user string query.

Expand Topics: Use pretrained “knowledge”

Example Query: “what’s the population of Richmond Virginia?”

1-Create a prompt
2-Constrain output to a list of strings
3-Combine together

def get_list_additional_topics_prompt(query: str) -> str:
    from datetime import datetime
    t = str(datetime.now())
    prompt = f"""The local time is {t}\n"""
    prompt += """Given the users query, produce a JSON list of other topics related to their query.\n"""
    prompt += f"""Here is their query: {query}\n"""
    prompt += """Provide a list of JSON strings of related topics: """
    return prompt

get_list_additional_topics_prompt()

The local time is 2025-06-02 15:09:23.197457
Given the users query, produce a JSON list of other topics related to their query.
Here is their query: what's the population of Richmond Virginia?
Provide a list of JSON strings of related topics:

def get_list_of_str_grammar(name="strings"):
    from pydantic import create_model
    schema = create_model(f"list_of_{name}", **{name: list[str]})
    json_list = guidance.json(name=name, schema=schema)
    return json_list

get_list_of_str_grammar()

{{G|140643206065584|G}}

def expand_topic_grammar(model, user_q: str):
    return (model
            + prompts.get_list_additional_topics_prompt(query=user_q)
            + get_list_of_str_grammar(name='topics'))

How does it do?

from guidance import gen
user_query = "what's the population of richmond virgnia?"
topics = expand_topic_grammar(g, user_q=user_query)['topics']
# Raw output
print(topics)

{"topics": ["population of virginia", "demographics of richmond", "richmond city facts", "virginia state facts", "us census data"]}

# Parse the string to an object
topics = json.loads(topics)['topics']
print(topics)

['population of virginia', 'demographics of richmond', 'richmond city facts', 'virginia state facts', 'us census data']

Now, perform the first search with all those topics!

First search: just use the API

Constrained generation is very powerful!

We’ve now seen the basic ingredients to 🔨 “tool” or “function” calls from the LLM

🔨 LLMs using tools is usually a mix of prompting and constrained generation
- Tell the model about the 🔨, what they do, their parameters, etc.
- Monitor LLM’s generated output for 🔨 calls
- Make the 🔨 call on behalf of the model
- Insert the 🔨 call output back into the context
- Continue generating

The LLM is just determining which 🔨 and its parameters

Guidance tools

Example straight from their README

import guidance

@guidance
def add(lm, input1, input2):
    lm += f' = {int(input1) + int(input2)}'
    return lm

@guidance
def subtract(lm, input1, input2):
    lm += f' = {int(input1) - int(input2)}'
    return lm

@guidance
def multiply(lm, input1, input2):
    lm += f' = {float(input1) * float(input2)}'
    return lm

@guidance
def divide(lm, input1, input2):
    lm += f' = {float(input1) / float(input2)}'
    return lm

o = g + '''\
1 + 1 = add(1, 1) = 2
2 - 3 = subtract(2, 3) = -1
'''
o = o + gen(max_tokens=15,
            tools=[add,
                   subtract,
                   multiply,
                   divide])
print(o)

1 + 1 = add(1, 1) = 2
2 - 3 = subtract(2, 3) = -1
3 * 4 = multiply(3, 4) = 12.0
4 / 5 = divide(4, 5) = 0.8

… couldn’t the LLM just write some Python script?

Model Context Protocol

Created by Antrhopic, Nov 2024

What does our smolagent say?

Find a good example demonstrating how to use model context protocol with huggingface smolagents library, you do not need to run the code, just find a good example

Out - Final answer: Here is an example demonstrating the use of the Model Context Protocol with SmolAgents:

from smolagents import ChatAgent, Tool
from smolagents.memory import MemoryModule

def search(query):
    # A simple function to simulate a web search tool
    return f"Search results for {query}"

tools = [Tool(name="search", func=search, description="A tool to perform web searches.")]
memory = MemoryModule()
agent = ChatAgent(tools=tools, memory=memory)

# Example interaction with the agent using Model Context Protocol
def interact_with_agent(user_input):
    response = agent.chat(user_input)
    print(f"User: {user_input}")
    print(f"Agent: {response}")

interact_with_agent("What is the population of New York City?")
interact_with_agent("How does this compare to Los Angeles?")

This example demonstrates how to set up a ChatAgent with tools and memory, allowing it to maintain context across interactions using the Model Context Protocol.

Wrong

Without MCP :(

Using MCP :D

MCP Client-server architecture

MCP Hosts: Process that needs access to resources through MCP
MCP Clients: Protocol clients that maintain 1:1 connections with servers
MCP Servers: Lightweight programs that each expose specific capabilities through the standardized Model Context Protocol
Local Data Sources: Your computer’s files, databases, and services that MCP servers can securely access
Remote Services: External systems available over the internet (e.g., through APIs) that MCP servers can connect to

MCP-ify our Vuln Search Tool

“Speculative” Risks

AGI is poorly defined, ASI is a sci-fi concept

Evidence for these risks are hard to generate

There is a lot of money involved… I wonder if that has anything to do with this hype!

Artificial intelligence risk management framework : generative artificial intelligence profile

(National Institute of Standards and Technology (US) 2024)

Summary

Companion resource for NIST AI Risk Management Framework (AI RMF)
- The RMF also has a “playbook”
- Does not cover speculative risks (we will tho)

Overview of risk
- Stage of the AI lifecycle: Dev. vs. Deployment vs. Ops vs. Decomm.
- Scopes: Application vs. Ecosystem
- Source of risk: training vs. design vs. operations
- Time scale: may be abrupt, may be prolonged, … may not

Adversarial machine learning : a taxonomy and terminology of attacks and mitigations

(Vassilev et al. 2024)

Quick tips

Prefer safetensors or GGUF, never use pickle
- Deserialization vulnerability (Section 3.2.1 Vassilev et al. (2024))
Monitor GPU usage with nvidia-smi
nvtop is also pretty good
Sometimes the weird issues are the quantized weights

Using my repo

Install a cuda build, but don’t add as a dependency

CMAKE_ARGS="-DGGML_CUDA=on" uv pip install --upgrade --force-reinstall llama-cpp-python --no-cache-dir

Force updating with correct flag to make it more permanent

CMAKE_ARGS="-DGGML_CUDA=on" uv add --force-reinstall llama-cpp-python --no-cache-dir

Build llama.cpp (C++) with CUDA support

cmake -B build -DGGML_CUDA=ON
cmake --build build --config Release

But we’ll be using the Python bindings

# Make sure to recursive clone
git clone --recurse-submodules https://github.com/abetlen/llama-cpp-python.git

export CMAKE_ARGS="-DGGML_CUDA=on" 
pip install -e '.[all]'

Can also download models from llama-cpp-python

What representation did rvasec14 capture

Training time attack: Poisoning Data

These “Trojans” may lurk in the pretrained models

Remember: Information is “stored” in the context and the weights

LLM weights are expensive to pretrain

So what do we do with all this “context”?
