FAQ
What is Marvin, and how does it work?
Marvin is an AI tool that brings ChatGPT into your normal engineering workflow by letting you intermix Python code with AI-powered constructs optimized for your use case. It works by using ChatGPT as a client, allowing you to access GPT-4, GPT-3.5, plugins, and more, on the platform. It is primarily accessed through its UI or by making raw API calls.
How do I set the model for Marvin?
Marvin supports multiple LLM models, including GPT-4 (gpt-4) and GPT-3.5 (gpt-3.5-turbo). To set the model, use the environment variable MARVIN_OPENAI_MODEL_NAME. Please note that while performance is better on GPT-4, it is slower and more expensive than GPT-3.5, and also less widely available to all OpenAI accounts.
The default model for Marvin is GPT-3.5, which guarantees that everyone can use Marvin "out of the box."
Is Marvin an async library, and can I directly await async coroutines?
Yes, Marvin is an async library as the vast majority of time is spent waiting for LLM responses to be returned via API. Therefore, it can be used natively in any other async library. However, the standard Python repl doesn't allow you to directly await async coroutines.
To integrate bots into synchronous frameworks, you can wrap async calls in asyncio.run(coro) or use convenience methods like Bot.say_sync(). Marvin uses a library called nest-asyncio to run nested event loops in a way that Python doesn't usually permit.
What license is Marvin available under, and where can I find its code?
Marvin is fully open-source under an Apache 2.0 license, and its code can be found on GitHub. It is built with 💙 by Prefect, and the company encourages developers to contribute to the project and help improve it.
How does Marvin compare to other AI tools on the market?
Marvin is known for its impressive AI functions, which use LLMs as a runtime and don't need any source code. This feature is what the company calls "whoa-code," which is perfect for developers who want to quickly integrate AI functionality into their workflow without spending too much time writing code. In terms of models, Marvin supports both GPT-4 and GPT-3.5, making it accessible to developers who don't have access to GPT-4 yet.
However, it is worth noting that while Marvin is efficient and user-friendly, it is still under rapid development, and developers may encounter sharp edges when working with it.
