+# RLinf LingbotVLA Click Bell GRPO
+
+This repository contains an RLinf checkpoint for LingbotVLA GRPO fine-tuning on the RoboTwin `click_bell` task.
+
+## Checkpoint Format
+
+The checkpoint is provided in RLinf actor checkpoint format:
+
+```text
+actor/model_state_dict/full_weights.pt
+actor/dcp_checkpoint/.metadata
+actor/dcp_checkpoint/__5_0.distcp
+actor/dcp_checkpoint/__7_0.distcp
+```
+
+For evaluation in RLinf, load the model through `runner.ckpt_path`:
+
+```bash
+runner.ckpt_path=/path/to/actor/model_state_dict/full_weights.pt
+```
+
+Use the LingbotVLA RoboTwin SFT base configuration from:
+
+```text
+robbyant/lingbot-vla-4b-posttrain-robotwin
+revision: 3e0c7c476bde3daaac00f79f3741a292a299f60a
+```
+
+## Evaluation
+
+Latest local regression evaluation on RoboTwin `click_bell` random setting:
+
+| Checkpoint | Task | Setting | Trajectories | Max Steps | eval/success_once | eval/return |
+| --- | --- | --- | ---: | ---: | ---: | ---: |
+| RLinf-lingbotvla-click-bell-grpo | click_bell | random | 320 | 400 | 0.9875 | 6.85 |
+
+Evaluation settings:
+
+```text
+config: robotwin_click_bell_grpo_lingbotvla_eval
+algorithm.eval_rollout_epoch=1
+algorithm.sampling_params.temperature_eval=-1
+env.eval.total_num_envs=320
+env.eval.max_episode_steps=400
+env.eval.max_steps_per_rollout_epoch=400
+env.eval.use_fixed_reset_state_ids=False
+env.eval.seeds_path=null
+env.eval.video_cfg.save_video=False
+```
+
+The evaluation logs are kept locally under:
+
+```text
+/mnt/public/lwb/artifacts/lingbot-vla-eval/click_bell_regression/20260615_140703
