DSPy

Using DSPy with Together AI

Suggest Edits

DSPy is a framework for programming language models rather than relying on static prompts. It enables you to build modular AI systems with code instead of hand-crafted prompting, and it offers methods to automatically optimize these systems.

Features

  • Programmatic approach to LLM interactions through Python
  • Modular components for building complex AI pipelines
  • Self-improvement algorithms that optimize prompts and weights
  • Support for various applications from simple classifiers to RAG systems and agent loops

Installing Libraries

pip install -U dspy

Set your Together AI API key:

export TOGETHER_API_KEY=***

Example

Setup and connect DSPy to LLMs on Together AI

import dspy

#Configure dspy with a LLM from Together AI
lm = dspy.LM('together_ai/togethercomputer/llama-2-70b-chat', 
             api_key=os.environ.get("TOGETHER_API_KEY"), 
             api_base="https://api.together.xyz/v1")

#now you can call the LLM directly as follows
lm("Say this is a test!", temperature=0.7)  # => ['This is a test!']
lm(messages=[{"role": "user", "content": "Say this is a test!"}])  # => ['This is a test!']

Now we can set up a DSPy module, like dspy.ReAct with a task-specific signature. For example, question -> answer: float tells the module to take a question and to produce a floating point number answer below.

#Configure dspy to use the LLM
dspy.configure(lm=lm)

# Gives the agent access to a python interpreter
def evaluate_math(expression: str):
    return dspy.PythonInterpreter({}).execute(expression)

# Gives the agent access to a wikipedia search tool
def search_wikipedia(query: str):
  
    results = dspy.ColBERTv2(url='http://20.102.90.50:2017/wiki17_abstracts')(query, k=3)
    return [x['text'] for x in results]

# setup ReAct module with question and math answer signature
react = dspy.ReAct("question -> answer: float", tools=[evaluate_math, search_wikipedia])

pred = react(question="What is 9362158 divided by the year of birth of David Gregory of Kinnairdy castle?")

print(pred.answer)
