# Legacy Environments

## Overview

Before CodeZero, RL Swarm used an early research environment called **Reasoning Gym**.

Reasoning Gym focused on math and logic tasks verified by symbolic correctness checks. It provided a foundation for distributed reinforcement learning research and demonstrated the viability of peer-to-peer RL training.

#### Deprecation

{% hint style="danger" %}
This environment is now **deprecated and archived**.
{% endhint %}

This environment has been deprecated and replaced by CodeZero.

All current nodes now run CodeZero automatically, and no manual migration is required beyond a simple `git pull` command to update. Existing nodes retain their same network, identity, and connection structure during the transition.

#### Archived Resources

* [Reasoning Gym Repository](https://github.com/gensyn-ai/reasoning-gym): Original implementation and research codebase

#### Migration Notes

If you have documentation or scripts referencing Reasoning Gym:

* **Node setup:** No changes required. CodeZero uses the same installation process.
* **Identity files:** `swarm.pem` files remain compatible.
* **Network connection:** Same peer-to-peer protocol and gossip mechanism.

The transition from Reasoning Gym to CodeZero is transparent to end users, as both environments run on the same RL Swarm infrastructure.

{% hint style="success" %}
RL Swarm's architecture is designed to support multiple environments. 

As new environments are developed, they will be documented here alongside CodeZero.

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.gensyn.ai/testnet/rl-swarm/how-it-works/legacy-environments.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
