tt-x4_temperature-t0p7-45-30B

tt-x4_temperature-t0p7 -- step 45 (X4 rollout temperature 0.7)

GRPO checkpoint from the TaskTrove hyperparameter sweep. Base model Qwen/Qwen3-Coder-30B-A3B-Instruct, trained on DCAgent/exp_rpt_multifile with SkyRL + Terminus-2; campaign verifier is pass_ratio shaping.

Checkpoint selection

global_step_45 was selected by the trailing-5 reward EMA (alpha = 1/3) over the full restart chain -- the highest-EMA aligned checkpoint (EMA 0.1962; step reward 0.2656; pass@8 0.4531; entropy 0.2981) among saved exports (hf_save_interval 5; first save excluded), per parse_skyrl_metrics.py --run_dir --save_every 5.

Run status -- terminated mid-horizon (elevated entropy)

The arm was terminated by the owner at step 66/80 (mid-horizon). Policy entropy had climbed to 4.40xx its step-1 value -- elevated and rising (the campaign entropy stop rule fires at 10x), i.e. the policy was degenerating before the kill. Step 45 is the best saved checkpoint before that decline. This is not a horizon result.
