The First Free AI Agent Builder is Here and it's Powerful
Summary
This video introduces Mistral AI's free custom AI agent builder at chat.mmistral.ai. It allows users to create specialized AI agents powered by Mistral models, offering an alternative to paid services like OpenAI's Custom GPTs and Claude Projects. The tutorial covers setting up agents with system prompts, utilizing few-shot prompting for examples, and deploying them for free use in the chat interface, with options for API use and testing requiring a pay-as-you-go subscription.
Key Insights
Mistral's agent builder provides a free alternative to other custom AI platforms.
This new feature, 'agents', allows users to create custom agents powered by different Mistral AI models. This is presented as a third option in the AI agent builder space, alongside OpenAI's Custom GPTs and Claude's Projects. Unlike Custom GPTs and Claude Projects, which require paid subscriptions to build, Mistral's builder is free to use for building and deploying agents within their chat interface.
Few-shot prompting uses input-output examples to guide the AI's desired response.
The builder supports few-shot prompting, where users provide examples of desired input and output. For instance, to turn a single sentence into a detailed LinkedIn post, one would provide the simple sentence as input and a more elaborated post as the output. The AI learns from these specific examples to generate more customized and detailed responses, a technique previously integrated into system prompts for other platforms but now a distinct feature here.
Mistral AI agents are free to build and use within the chat interface.
Users can build and deploy agents for free within the Mistral chat interface. This is a key differentiator from paid services like Custom GPTs and Claude Projects. The only costs arise if users choose to utilize the API for application development or opt for a subscription for testing during the building process.

Introduction to Mistral AI Agent Builder
Mistral AI offers a free tool to build custom AI agents with specific instructions.
A new AI agent builder is available where users can create custom AI agents with a very specific set of instructions completely for free. The website to access this tool is chat.mmistral.ai. Mistral AI is a French startup that provides free access to its large language models, currently powered by Mistro Large 2, which is their best available model.
Mistral's agent builder provides a free alternative to other custom AI platforms.
This new feature, 'agents', allows users to create custom agents powered by different Mistral AI models. This is presented as a third option in the AI agent builder space, alongside OpenAI's Custom GPTs and Claude's Projects. Unlike Custom GPTs and Claude Projects, which require paid subscriptions to build, Mistral's builder is free to use for building and deploying agents within their chat interface.
Custom AI agents are highly valuable tools for specific tasks.
AI agents, or custom GPTs, are considered among the best parts of AI technology. They are designed for very specific tasks and are used more frequently than other AI tools by experienced users who have tested thousands of AI tools. The video author has made many videos comparing Custom GPTs due to their utility.
Building a Custom Mistral AI Agent
Agent creation involves selecting a model, adjusting temperature for creativity, and defining instructions.
To create an agent, users select a model (Mistral Large 2 is recommended). The 'temperature' option controls randomness: lower values (closer to zero) make output more predictable, while higher values (closer to one) increase creativity and randomness. This slider is a feature not commonly found in basic interfaces of other tools.
System prompts provide a specific instruction set for the AI agent's behavior and tone.
Users can input a system prompt, which acts as custom instructions for the specific bot being built. This dictates how the AI agent should behave, its tone, writing style, and reading level. This allows for agents that are distinct from general chatbot interfaces like ChatGPT or Mistral's base chat.
Few-shot prompting uses input-output examples to guide the AI's desired response.
The builder supports few-shot prompting, where users provide examples of desired input and output. For instance, to turn a single sentence into a detailed LinkedIn post, one would provide the simple sentence as input and a more elaborated post as the output. The AI learns from these specific examples to generate more customized and detailed responses, a technique previously integrated into system prompts for other platforms but now a distinct feature here.
The example demonstrates creating a LinkedIn post generator agent.
An example agent is created to transform a single sentence into a professional LinkedIn post. The system prompt is generated by pasting a simple instruction ('turn a single sentence into a LinkedIn post') into a prompt designer, which then creates a more detailed instruction like: 'You are an AI model designed to transform a single sentence into a professional LinkedIn post.' Few-shot prompting is then applied with an example input sentence and a corresponding elaborate LinkedIn post output.
Agents are named and deployed to the Mistral chat interface or via API.
After configuration, the agent is named (e.g., 'LinkedIn post generator') and deployed. Deployment options include use through their API (for developers) or within the Mistral chat interface. Deploying to the chat interface allows for free use by the creator and others.
Pricing and Usage
Mistral AI agents are free to build and use within the chat interface.
Users can build and deploy agents for free within the Mistral chat interface. This is a key differentiator from paid services like Custom GPTs and Claude Projects. The only costs arise if users choose to utilize the API for application development or opt for a subscription for testing during the building process.
API usage and testing subscriptions are pay-as-you-go.
While building and using agents is free, using the API incurs pay-as-you-go costs based on tokens. Testing agents during development may also require setting up a subscription, which has a free trial. Pricing for API usage varies by model; Mistral Large 2 costs $3 per million input tokens and $9 per million output tokens.
The generated LinkedIn post example is more comprehensive and engaging.
An example shows the agent successfully transforming a simple sentence into a much more comprehensive and engaging LinkedIn post, demonstrating its effectiveness in remixing content for better engagement on social media, newsletters, and email copy.
Mistral's current agent builder lacks document upload capability found in competitors.
A significant limitation of Mistral's agent builder is the inability to upload custom documents to create a knowledge base, a feature available in OpenAI's Custom GPTs and Claude Projects. The author hopes this feature will be added in future updates.
