As AI systems grow in scale and generality, RL has become a critical layer for alignment. However, most co-located RL frameworks face a deadlock: inference interrupts training, training delays inference.

Echo is Gradient’s distributed RL framework, running on everyday consumer devices.

## Dual Swarm Architecture

Echo breaks the cycle by decoupling them into two independent swarms:

* Inference on distributed devices (via [Parallax](/the-open-intelligence-stack/parallax.md))
* Training on high-performance clusters

## Echo Modes

We have open-sourced several early explorations with Echo, including:&#x20;

* A 7B math model beating Qwen2.5–32B
* A 30B Sokoban model outperforming DeepSeek-R1 & GPT-OSS-120B
* A 32B LoRA logic model ≥99% accuracy&#x20;
