How to Use Sundae_Bar (Subnet 121) to Build Your Own AI Agent

There is a quiet shift happening in AI right now. We are moving from tools to teammates, from isolated models to coordinated, task-driven agents that can actually work alongside humans.

But there is a problem.

Developers are building thousands of AI agents across different niches, yet discovery remains fragmented, deployment is clunky, and trust is still a barrier for real-world adoption.

This is where Sundae_Bar (Bittensor Subnet 121) steps in with a powerful idea: What if AI agents had a unified marketplace, just like apps?

Sundae_Bar is that marketplace, a place where AI agents are not just listed, but discovered, tested, and deployed as real digital coworkers.

Features of Sundae_Bar

Sundae_Bar functions as an “App Store for AI Agents,” but with deeper infrastructure designed for both builders and users. Its capabilities are structured around solving three key problems: discovery, deployment, and monetization.

1. Agent Directory and Discovery

Sundae_Bar aggregates AI agents into a structured, searchable marketplace where users can easily find what they need:

a. A curated directory spanning multiple domains such as HR, marketing, finance, and development,

b. Detailed agent profiles explaining capabilities, use cases, and performance,

c. Smart recommendations based on user intent or task requirements, and

d. Early examples include agents like Lucy for HR automation, AROK for crypto trading, and Marketing Mark for content generation.

Instead of hunting across fragmented tools, users can now discover and evaluate agents in one place.

2. A Full Stack Platform for AI Developers

For builders, Sundae_Bar is not just a listing platform. It is an end-to-end ecosystem for launching and scaling AI agents:

a. Tools to build, host, and deploy agents seamlessly,

b. Dedicated dashboards with analytics and performance insights,

c. Flexible monetization options including subscriptions and usage-based pricing,

d. Built-in compliance layers such as KYC and AML to support enterprise adoption, and

e. Individual storefronts where developers can brand and position their agents.

In practice, this turns every developer into a digital merchant, with Sundae_Bar handling distribution and infrastructure.

3. A Seamless Experience for Businesses and Users

For end users, especially businesses, the platform removes friction from adopting AI.

a. Search agents by use case or describe a task to get matched recommendations,

b. Test agents through demos or trial environments before committing,

c. Integrate agents directly into workflows with minimal setup, and

d. Access a trusted environment where security and verification are prioritized.

The experience is that deploying an AI agent should feel as natural as installing an app.

How to Build and Launch an AI Agent on Sundae Bar

Sundae Bar is designed to lower the barrier for developers while maintaining quality and trust across the marketplace. The process of launching an agent follows a structured but accessible flow.

Step 1: Develop Your Agent

Start by building an agent tailored to a specific use case. The platform favors agents that solve clear, real-world problems rather than generic capabilities.

Step 2: Submit to the Marketplace

Developers can sign-up to Sundae_Bar through their email or GitHub account, submit their agents through a structured onboarding process, which includes:

a. Defining the agent’s functionality and target use case,

b. Providing documentation and usage details, and

c. Setting pricing models or access terms.

NB: Developers can also put in for various challenges, build and submit solutions to that effect.

Step 3: Compliance and Verification

Before going live, agents pass through basic compliance and security checks. This ensures that:

a. Enterprise users can trust what they are deploying, and

b. Malicious or low-quality agents are filtered out.

Step 4: Launch Your Storefront

Once approved, the agent is listed on the marketplace with its own profile page. Developers gain access to:

a. Performance analytics,

b. User engagement metrics, and

c. Monetization tracking.

Step 5: Iterate and Scale

After launch, developers can continuously improve their agents based on user feedback while scaling distribution through the platform’s discovery engine.

Conclusion

Sundae_Bar represents something bigger than just another subnet. It is an attempt to standardize how AI agents are discovered, trusted, and deployed in a world that is rapidly moving toward automation.

By connecting developers with users through a unified marketplace, it removes one of the biggest bottlenecks in the agent economy.

More importantly, it reframes how we think about AI. Not as tools you occasionally use, but as teammates you can hire, manage, and scale.

At this rate, Sundae Bar will not just support the future of AI, it is quietly becoming its foundation.
