What is Marvin AI?
A battery-powered AI-powered software development library. It is intended to make the incorporation of AI capabilities into software systems easier.
Marvin AI presents the notion of AI Functions, which vary from typical functions in that they create on-demand outputs using AI rather than traditional source code. These AI Functions enable developers to accomplish tasks like extracting entities from web pages, assessing sentiment, or classifying objects in a database by expressing their requirements and running the function.
Marvin AI’s AI Functions interact with native data types, making it simple to incorporate them into any codebase and link them together to construct complicated pipelines. The library takes a “functional prompt engineering” approach, changing the signature of using AI from (str) -> str to (**kwargs) -> Any, giving for more flexibility in function calls.
Marvin AI provides flexible bots in addition to AI Functions. These bots are intelligent artificial intelligence helpers that may be programmed with unique instructions, personalities, or responsibilities. They can use custom plugins and external knowledge to create a history of every chat thread. It’s worth mentioning that Marvin AI’s AI Functions are a form of bot.
Marvin AI offers a fully functional Text User Interface (TUI) that records threads across numerous bots and gives a conversational interface for controlling them to make dealing with bots easier.
While Marvin AI is a fictitious library, it demonstrates the notion of integrating AI capabilities in a user-friendly manner with AI Functions and adaptable bots. Please let me know if you have any additional questions or if there is anything else I can do for you.
Features
- AI Functions: Marvin AI allows you to construct AI functions that can handle structured data without using traditional source code.
- Flexible Bots: With Marvin AI, you can create bots with personalities. These bots can use the AI functions you develop and can use plugins to expand their capabilities.
- Text User Interface (TUI): Marvin AI provides a fully featured TUI that allows you to interact with and manage bots using a conversational interface.
- Plugin Support: Custom plugins may be used to extend the capabilities of your bots. These plugins offer functionality and allow you to extend your bots’ capabilities beyond the built-in features.
- Knowledge Storage: Marvin AI allows you to store information that bots may access and use throughout discussions and interactions.
- Python API, CLI, and FastAPI Server: Marvin AI is offered as a Python API, CLI, and FastAPI Server, allowing you to incorporate its capabilities into your existing codebase.
Installation
Install Marvin by running the following command:
pip install marvin
Once installed, you can start a chat session with Marvin by running the following command:
marvin chat
Create a bot:
marvin bots create ObiWanKenoBot -p "knows every Star Wars meme"
Chat with it:
marvin chat -b ObiWanKenoBot

When to Use Marvin:
Marvin is a strong-willed, high-level library whose objective is to integrate AI tools into software development. There are several compelling reasons to use Marvin:
- You need an AI function that can handle structured data. Marvin applies the power of artificial intelligence to native data structures, allowing you to design functions that would otherwise be difficult or impossible to write. For example, you may utilize AI functions to produce JSON documents from HTML material, extract keywords that fit specific criteria, or characterize emotion – all without writing any traditional source code.
- You want an AI assistant in your code. To handle complicated issues, Marvin’s bots can follow instructions and have dialogues. They can make use of custom plugins and external knowledge. They are intended to be incorporated within your software, but you may also expose them directly to your users!
- You want to confidently implement cutting-edge AI technologies without having to make too many decisions. Successful use of LLMs requires careful consideration of prompts, data preparation, and infrastructure. Our target user is more interested in utilizing AI systems than in developing AI systems. As a result, Marvin is designed to make the adoption of this technology as simple as possible by optimizing for meaningful outcomes. Months of real-world use have hardened Marvin’s prompts, and they will continue to improve over time.
When Not to Use Marvin AI:
There are a few reasons NOT to use Marvin:
- You want complete control over the AI. Marvin is a high-level library that does not normally provide LLM settings to users (with a few exceptions). We picked settings that produce the greatest results in most conditions, taking into account Marvin’s built-in suggestions.
- You want an AI copilot to help you write programming. Marvin’s goal is not to assist you in writing source code; rather, he is to assist you in doing things that are difficult or impossible to explain in source code. That may include boring tasks like building a function to extract the names of animals typically found in North America from an email (yeah, it’s a ridiculous example, but it’s possible). Modern LLMs excel at complicated reasoning, which Marvin allows you to include into your code in a way that feels natural and clear.
- You want to employ different LLM models. Marvin is intended to compete with OpenAI’s GPT-4 and GPT-3.5 models. While those models may be expanded in the future, we’ve found that prompts developed for one model rarely transition effectively to others without adjustment. We’ve opted to limit the library’s scope for the time being in order to optimize its use.
- You want complete control over your prompts. Marvin, as a “functional prompt engineering” platform, receives user inputs and creates prompts that are likely to provide the desired consequence, even if they are not exactly what the user stated. Marvin does not anticipate users to submit the LLM entirely raw prompts.
- You’re on the lookout for the Ultimate Question. Even Marvin, who is extremely brilliant, couldn’t answer the Ultimate Question of Life, the Universe, and Everything. If you’re looking for existential enlightenment, you may have to go beyond our favorite paranoid android.
