# Reverse Text Model Qwen3-0.6B

Simple model that was RL FT for 20 steps / epochs after SFT to reverse text using [prime-rl](https://github.com/PrimeIntellect-ai/prime-rl/) (RL Training) and [reverse-text](https://github.com/PrimeIntellect-ai/prime-environments/tree/main/environments/reverse_text) (RL Environment). See the improvement in results:

## Comparison with SFT (base) model

The reward (correctness score) distribution has improved for the RLFT model across all rollouts.

At an instance level, if we compare the best scores across rollouts, we see a mean improvement of 3.73%. But a maximum of ~30% and reduction of ~3%
