Mojentic is a framework that provides a simple and flexible way to interact with Large Language Models (LLMs). It offers integration with various LLM providers and includes tools for structured output generation, task automation, and more. With comprehensive support for all OpenAI models including GPT-5 and automatic parameter adaptation, Mojentic handles the complexities of different model types seamlessly. The future direction is to facilitate a team of agents, but the current focus is on robust LLM interaction capabilities.
- LLM Integration: Support for multiple LLM providers (OpenAI, Ollama)
- Latest OpenAI Models: Full support for GPT-5, GPT-4.1, and all reasoning models (o1, o3, o4 series)
- Automatic Model Adaptation: Seamless parameter handling across different OpenAI model types
- Structured Output: Generate structured data from LLM responses using Pydantic models
- Tools Integration: Utilities for date resolution, image analysis, and more
- Multi-modal Capabilities: Process and analyze images alongside text
- Simple API: Easy-to-use interface for LLM interactions
- Future Development: Working towards an agent framework with team coordination capabilities
- Python 3.11+
- Ollama (for local LLM support)

We recommend using uv for fast, reliable Python project management.

# Initialize with OpenAI (supports all models including GPT-5, GPT-4.1, reasoning models)
openai_llm = LLMBroker(model="gpt-5", gateway=OpenAIGateway(api_key="your_api_key"))
# Or use other models: "gpt-4o", "gpt-4.1", "o1-mini", "o3-mini", etc.
# Or use Ollama for local LLMs
ollama_llm = LLMBroker(model="qwen3:32b")
# Simple text generation
result = openai_llm.generate(messages=[LLMMessage(content='Hello, how are you?')])
print(result)
# Generate structured output

object_model=Sentiment
)
print(sentiment.label)
# Use tools with the LLM
result = openai_llm.generate(
messages=[LLMMessage(content='What is the date on Friday?')],
tools=[ResolveDateTool()]
)
print(result)
# Image analysis
result = openai_llm.generate(messages=[
LLMMessage(content='What is in this image?', image_paths=['path/to/image.jpg'])
])
print(result)OpenAIGateway now supports environment-variable defaults so you can get started without hardcoding secrets:
- If you omit
api_key, it will use theOPENAI_API_KEYenvironment variable. - If you omit
base_url, it will use theOPENAI_API_ENDPOINTenvironment variable (useful for custom endpoints like Azure/OpenAI-compatible proxies). - Precedence: values you pass explicitly to
OpenAIGateway(api_key=..., base_url=...)always override environment variables.
Examples:
from mojentic.llm import LLMBroker
from mojentic.llm.gateways import OpenAIGateway
# 1) Easiest: rely on environment variables
# export OPENAI_API_KEY=sk-...
# export OPENAI_API_ENDPOINT=https://api.openai.com/v1 # optional
llm = LLMBroker(
model="gpt-4o-mini",
gateway=OpenAIGateway() # picks up OPENAI_API_KEY/OPENAI_API_ENDPOINT automatically
)
# 2) Explicitly override one or both values
llm = LLMBroker(
model="gpt-4o-mini",
gateway=OpenAIGateway(api_key="your_key", base_url="https://api.openai.com/v1")
)The framework automatically handles parameter differences between model types, so you can switch between any models without code changes.
Some models have specific parameter restrictions that are automatically handled:
- GPT-5 Series: Only supports
temperature=1.0(default). Other temperature values are automatically adjusted with a warning. - o1 & o4 Series: Only supports
temperature=1.0(default). Other temperature values are automatically adjusted with a warning. - o3 Series: Does not support the
temperatureparameter at all. The parameter is automatically removed with a warning. - All Reasoning Models (o1, o3, o4, GPT-5): Use
max_completion_tokensinstead ofmax_tokens, and have limited tool support.
The framework will automatically adapt parameters and log warnings when unsupported values are provided.

pip-audit # Dependency vulnerabilitiesThe agentic aspects of this framework are in the highest state of flux. The first layer has stabilized, as have the simpler parts of the second layer, and we're working on the stability of the asynchronous pubsub architecture. We expect Python 3.14 will be the real enabler for the async aspects of the second layer.
