## 🚀 The Future of Rasa: Hello Rasa
**Building reliable AI agents just got easier.**
[**Hello Rasa**](https://hello.rasa.ai/?utm_source=github&utm_medium=website&utm_campaign=) is our new interactive playground for prototyping AI agents. It combines LLM fluency with the reliability of business logic using our **CALM** (Conversational AI with Language Models) engine.
### Why switch to Hello Rasa?
* **No setup required:** Open the playground, pick a template (Banking, Telecom, Support), and start building in your browser.
* **No NLU training:** We have moved beyond intents. The LLM handles dialogue understanding while you define the business flows.
* **Built-in copilot:** A specialized AI assistant helps you generate code, debug flows, and expand your agent instantly.
* **Production ready:** Hello Rasa is not just a toy. Export your agent to the Rasa Platform when you are ready to scale.
### Core concepts
* **CALM:** Combines LLM flexibility with strict business logic. The LLM understands the user; the code enforces the rules.
* **Flows:** Describe logical steps (e.g., collect money, transfer funds) rather than rigid dialogue trees.
* **Inspector:** See real-time decision-making. No black boxes.

## 🧠 Join the Agent Engineering Community
We are building a home for people shipping real-world AI agents.
Agent Engineering is evolving faster than any single framework. This is a vendor-neutral space to discuss architectures, memory, orchestration, and safety with builders across the industry.
### What you get:
* **Network:** Meet engineers building production agents
* **Learn:** Discuss practical patterns, not just theory
* **Access:** Direct influence on the Hello Rasa roadmap and early access to features
| Channel | Purpose |
| :--- | :--- |
| **#agent-design** | Architectures, reasoning, memory, testing |
| **#showcase** | Show your builds, demos, and repos |
| **#ask-anything** | Debugging and workflow questions |
