Model Card for RLFR-Qwen2.5-VL-7B-Instruct
RLFR-Qwen2.5-VL-7B-Instruct is trained from Qwen2.5-VL-7B-Instruct with the RLFR framework, which introduces the flow reward derived from latent space, extending RLVR with latent reward utilization.
Model Details
Key Features
- 💡 Sound Flow Environment: RLFR establishes the flow fields of policy latents from either off-policy high-quality data and on-policy rejection sampling data, and the velocity deviations of policy latents within it are quantified to serve as a reward signal. We first demonstrate a well-established flow field can be a sound reward environment and highlight the much underexplored yet highly expressive latent space.
- 🛠️ Training Details
- Underscoring the timesteps priority in flow reward yielding, and recommend for larger timesteps with less noisy, given by the accuracy of velocity prediction.
- Metrics of online rejection-sampling are flexible to direct the constitution of reference flow for reward calculation.
- 📈 Reward Behavior Flow rewards enable arbitrary expert off-policy data as reference for constituting reward signal. Additionally, flow rewards rely on efficient context dependence that natively compressed in the latent space rather than individual denotation in the token space for context comprehending.
