# LlamaBot: A Pythonic bot interface to LLMs

LlamaBot implements a Pythonic interface to LLMs,
making it much easier to experiment with LLMs in a Jupyter notebook
and build Python apps that utilize LLMs.
All models supported by [LiteLLM](https://github.com/BerriAI/litellm) are supported by LlamaBot.

## Install LlamaBot

To install LlamaBot:

```python
pip install llamabot==0.12.11
```

This will give you the minimum set of dependencies for running LlamaBot.

To install all of the optional dependencies, run:

```python
pip install "llamabot[all]"
```



## Get access to LLMs

### Option 1: Using local models with Ollama

LlamaBot supports using local models through Ollama.
To do so, head over to the [Ollama website](https://ollama.ai) and install Ollama.
Then follow the instructions below.

### Option 2: Use an API provider

#### OpenAI

If you have an OpenAI API key, then configure LlamaBot to use the API key by running:

```bash
export OPENAI_API_KEY="sk-your1api2key3goes4here"
```

#### Mistral

If you have a Mistral API key, then configure LlamaBot to use the API key by running:

```bash
export MISTRAL_API_KEY="your-api-key-goes-here"
```

#### Other API providers

Other API providers will usually specify an environment variable to set.
If you have an API key, then set the environment variable accordingly.

### Option 3: Using local models with LMStudio

LlamaBot supports using local models through LMStudio via LiteLLM.
To use LMStudio with LlamaBot:

1. Install and set up [LMStudio](https://lmstudio.ai/)
2. Load your desired model in LMStudio
3. Start the local server in LMStudio (usually runs on `http://localhost:1234`)
4. Set the environment variable for LMStudio's API base:

```bash
export LM_STUDIO_API_BASE="http://localhost:1234"
```

5. Use the model with LlamaBot using the `lm_studio/` prefix:

```python
from llamabot import SimpleBot

system_prompt = "You are a helpful assistant."
bot = SimpleBot(
    system_prompt,
    model_name="lm_studio/your-model-name"  # Use lm_studio/ prefix
)
```

Replace `your-model-name` with the actual name of the model you've loaded in LMStudio. LlamaBot can use any model provider that LiteLLM supports, and LMStudio is one of the many supported providers.

## How to use

### SimpleBot

The simplest use case of LlamaBot
is to create a `SimpleBot` that keeps no record of chat history.
This is effectively the same as a _stateless function_
that you program with natural language instructions rather than code.
This is useful for prompt experimentation,
or for creating simple bots that are preconditioned on an instruction to handle texts
and are then called upon repeatedly with different texts.

#### Using `SimpleBot` with an API provider

For example, to create a Bot that explains a given chunk of text
like Richard Feynman would:

```python
from llamabot import SimpleBot

system_prompt = "You are Richard Feynman. You will be given a difficult concept, and your task is to explain it back."
feynman = SimpleBot(
  system_prompt,
  model_name="gpt-3.5-turbo"
)
```

For using GPT, you need to have the `OPENAI_API_KEY` environment variable configured. If you want to use `SimpleBot` with a local Ollama model, [check out this example](#using-simplebot-with-a-local-ollama-model)

Now, `feynman` is callable on any arbitrary chunk of text and will return a rephrasing of that text in Richard Feynman's style (or more accurately, according to the style prescribed by the `system_prompt`).
For example:

```python
prompt = """
Enzyme function annotation is a fundamental challenge, and numerous computational tools have been developed.
However, most of these tools cannot accurately predict functional annotations,
such as enzyme commission (EC) number,
for less-studied proteins or those with previously uncharacterized functions or multiple activities.
We present a machine learning algorithm named CLEAN (contrastive learning–enabled enzyme annotation)
to assign EC numbers to enzymes with better accuracy, reliability,
and sensitivity compared with the state-of-the-art tool BLASTp.
The contrastive learning framework empowers CLEAN to confidently (i) annotate understudied enzymes,
(ii) correct mislabeled enzymes, and (iii) identify promiscuous enzymes with two or more EC numbers—functions
that we demonstrate by systematic in silico and in vitro experiments.
We anticipate that this tool will be widely used for predicting the functions of uncharacterized enzymes,
thereby advancing many fields, such as genomics, synthetic biology, and biocatalysis.
"""
feynman(prompt)
```

This will return something that looks like:

```text
Alright, let's break this down.

Enzymes are like little biological machines that help speed up chemical reactions in our
bodies. Each enzyme has a specific job, or function, and we use something called an
Enzyme Commission (EC) number to categorize these functions.

Now, the problem is that we don't always know what function an enzyme has, especially if
it's a less-studied or new enzyme. This is where computational tools come in. They try
to predict the function of these enzymes, but they often struggle to do so accurately.

So, the folks here have developed a new tool called CLEAN, which stands for contrastive
learning–enabled enzyme annotation. This tool uses a machine learning algorithm, which
is a type of artificial intelligence that learns from data to make predictions or
decisions.

CLEAN uses a method called contrastive learning. Imagine you have a bunch of pictures of
cats and dogs, and you want to teach a machine to tell the difference. You'd show it
pairs of pictures, some of the same animal (two cats or two dogs) and some of different
animals (a cat and a dog). The machine would learn to tell the difference by contrasting
the features of the two pictures. That's the basic idea behind contrastive learning.

CLEAN uses this method to predict the EC numbers of enzymes more accurately than
previous tools. It can confidently annotate understudied enzymes, correct mislabeled
enzymes, and even identify enzymes that have more than one function.

The creators of CLEAN have tested it with both computer simulations and lab experiments,
and they believe it will be a valuable tool for predicting the functions of unknown
enzymes. This could have big implications for fields like genomics, synthetic biology,
and biocatalysis, which all rely on understanding how enzymes work.
```

#### Using `SimpleBot` with a Local Ollama Model

If you want to use an Ollama model hosted locally,
then you would use the following syntax:

```python
from llamabot import SimpleBot

system_prompt = "You are Richard Feynman. You will be given a difficult concept, and your task is to explain it back."
bot = SimpleBot(
    system_prompt,
    model_name="ollama_chat/llama2:13b"
)
```

Simply specify the `model_name` keyword argument following the `<provider>/<model name>` format. For example:

* `ollama_chat/` as the prefix, and
* a model name from the [Ollama library of models](https://ollama.ai/library)

All you need to do is make sure Ollama is running locally;
see the [Ollama documentation](https://ollama.ai/) for more details.
(The same can be done for the `QueryBot` class below!)

The `model_name` argument is optional. If you don't provide it, Llamabot will try to use the default model. You can configure that in the `DEFAULT_LANGUAGE_MODEL` environment variable.

### SimpleBot with memory for chat functionality

If you want chat functionality with memory (similar to what ChatBot provided), you can use SimpleBot with a LanceDBDocStore as memory. This allows the bot to remember previous conversations:

```python
from llamabot import SimpleBot, LanceDBDocStore

# Create a bot with memory
system_prompt = "You are Richard Feynman. You will be given a difficult concept, and your task is to explain it back."
chat_memory = LanceDBDocStore(table_name="feynman_chat")
feynman = SimpleBot(
    system_prompt,
    chat_memory=chat_memory,
    model_name="gpt-3.5-turbo"
)

# Have a conversation
response1 = feynman("Can you explain quantum mechanics?")
print(response1)

# The bot remembers the previous conversation
response2 = feynman("Can you give me a simpler explanation?")
print(response2)
```

The LanceDBDocStore will persist your conversation history using vector embeddings, allowing the bot to semantically search through previous exchanges and maintain context across multiple interactions.

### QueryBot

The final bot provided is a QueryBot.
This bot lets you query a collection of documents.
QueryBot now works with a docstore that you create first, making it more modular.

Here's how to use QueryBot with a docstore:

```python
from llamabot import QueryBot
from llamabot.docstore import LanceDBDocStore
from pathlib import Path

# First, create a docstore and add your documents
docstore = LanceDBDocStore(table_name="eric_ma_blog")
docstore.add_documents([
    Path("/path/to/blog/post1.txt"),
    Path("/path/to/blog/post2.txt"),
    # ... more documents
])

# Then, create a QueryBot with the docstore
bot = QueryBot(
  system_prompt="You are an expert on Eric Ma's blog.",
  docstore=docstore,
  # Optional:
  # model_name="gpt-3.5-turbo"
  # or
  # model_name="ollama_chat/mistral"
)

result = bot("Do you have any advice for me on career development?")
```

You can also use an existing docstore:

```python
from llamabot import QueryBot
from llamabot.docstore import LanceDBDocStore

# Load an existing docstore
docstore = LanceDBDocStore(table_name="eric_ma_blog")

# Create QueryBot with the existing docstore
bot = QueryBot(
  system_prompt="You are an expert on Eric Ma's blog",
  docstore=docstore,
  # Optional:
  # model_name="gpt-3.5-turbo"
  # or
  # model_name="ollama_chat/mistral"
)

result = bot("Do you have any advice for me on career development?")
```

For more explanation about the `model_name`, see [the examples with `SimpleBot`](#using-simplebot-with-a-local-ollama-model).

### ImageBot

With the release of the OpenAI API updates,
as long as you have an OpenAI API key,
you can generate images with LlamaBot:

```python
from llamabot import ImageBot

bot = ImageBot()
# Within a Jupyter notebook:
url = bot("A painting of a dog.")

# Or within a Python script
filepath = bot("A painting of a dog.")

# Now, you can do whatever you need with the url or file path.
```

If you're in a Jupyter Notebook,
you'll see the image show up magically as part of the output cell as well.

### Experimentation

Automagically record your prompt experimentation locally on your system
by using llamabot's `Experiment` context manager:

```python
from llamabot import Experiment, prompt, metric

@prompt
def sysprompt():
    """You are a funny llama."""

@prompt
def joke_about(topic):
    """Tell me a joke about {{ topic }}."""

@metric
def response_length(response) -> int:
    return len(response.content)

with Experiment(name="llama_jokes") as exp:
    # You would have written this outside of the context manager anyways!
    bot = SimpleBot(sysprompt(), model_name="gpt-4o")
    response = bot(joke_about("cars"))
    _ = response_length(response)
```

And now they will be viewable in the locally-stored message logs:

![](./docs/cli/log-viewer/experiments.webp)

## CLI Demos

Llamabot comes with CLI demos of what can be built with it and a bit of supporting code.

Here is one where I expose a chatbot directly at the command line using `llamabot chat`:

[![Watch the terminal session on Asciinema](https://asciinema.org/a/594332.png)](https://asciinema.org/a/594332)

And here is another one where `llamabot` is used as part of the backend of a CLI app
to chat with one's Zotero library using `llamabot zotero chat`:

[![Watch the terminal session on Asciinema](https://asciinema.org/a/594326.png)](https://asciinema.org/a/594326)


And finally, here is one where I use `llamabot`'s `SimpleBot` to create a bot
that automatically writes commit messages for me.

## Caching

LlamaBot uses a caching mechanism to improve performance and reduce unnecessary API calls. By default, all cache entries expire after 1 day (86400 seconds). This behavior is implemented using the `diskcache` library.

### Cache Configuration

The cache is automatically configured when you use any of the bot classes (`SimpleBot` or `QueryBot`). You don't need to set up the cache manually.

### Cache Location

The default cache directory is located at:

```
~/.llamabot/cache
```

### Cache Timeout

The cache timeout can be configured using the `LLAMABOT_CACHE_TIMEOUT` environment variable. By default, the cache timeout is set to 1 day (86400 seconds). To customize the cache timeout, set the `LLAMABOT_CACHE_TIMEOUT` environment variable to the desired value in seconds. For example:

```
export LLAMABOT_CACHE_TIMEOUT=3600
```

This will set the cache timeout to 1 hour (3600 seconds).

## Contributing

### New features

New features are welcome!
These are early and exciting days for users of large language models.
Our development goals are to keep the project as simple as possible.
Features requests that come with a pull request will be prioritized;
the simpler the implementation of a feature (in terms of maintenance burden),
the more likely it will be approved.
