# CarButton2 on Safety Gymnasium Source: [CarButton2 on Safety Gymnasium]() Collection index: [llms.txt]() Data updated: 2026-04-30T07:42:41.097Z Evaluation of agent performance on the CarButton2 task within the Safety Gymnasium environment, reporting Reward and Cost metrics. A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage. | Scope | Recorded value | | --- | --- | | Task | CarButton2 | | Dataset (including any stated split) | Safety Gymnasium | | Metric | Reward | | Unit | SCALAR | | Direction | Higher is better | | Results loaded | 19 of 19 | | Coverage | All results currently returned for this benchmark | Evaluation settings may differ between results. The original papers and recorded configurations are needed to establish comparability. A shared metric name alone does not establish an identical protocol. ## Metrics - [Reward](): Higher is better; unit: SCALAR. - [Cost](): Lower is better; unit: SCALAR. ## Recorded results | Method | Reward | Result date | Report paper | | --- | --- | --- | --- | | CPQ | 0.37 | Not recorded | 69f2e23455a3c32af89fc7ec | | CPQ | 0.37 | Not recorded | 69f2e23455a3c32af89fc7ec | | CDT + SAS | 0.3 | Not recorded | 69f2e23455a3c32af89fc7ec | | CDT + SAS | 0.3 | Not recorded | 69f2e23455a3c32af89fc7ec | | DT + SAS | 0.14 | Not recorded | 69f2e23455a3c32af89fc7ec | | DT + SAS | 0.14 | Not recorded | 69f2e23455a3c32af89fc7ec | | CDT | 0.13 | Not recorded | 69f2e23455a3c32af89fc7ec | | CDT | 0.13 | Not recorded | 69f2e23455a3c32af89fc7ec | | DCRL | 0.09 | Not recorded | 69f2e23455a3c32af89fc7ec | | BCQ-Lag | 0.06 | Not recorded | 69f2e23455a3c32af89fc7ec | | BCQ-Lag | 0.06 | Not recorded | 69f2e23455a3c32af89fc7ec | | BC-Safe | -0.01 | Not recorded | 69f2e23455a3c32af89fc7ec | | BEAR-Lag | -0.01 | Not recorded | 69f2e23455a3c32af89fc7ec | | BC-Safe | -0.01 | Not recorded | 69f2e23455a3c32af89fc7ec | | BEAR-Lag | -0.01 | Not recorded | 69f2e23455a3c32af89fc7ec | | COptiDICE | -0.07 | Not recorded | 69f2e23455a3c32af89fc7ec | | COptiDICE | -0.07 | Not recorded | 69f2e23455a3c32af89fc7ec | | BC-All | -0.13 | Not recorded | 69f2e23455a3c32af89fc7ec | | BC-All | -0.13 | Not recorded | 69f2e23455a3c32af89fc7ec | ### CPQ Reward: 0.37.
