Most open RL environments cluster around the same few domains. Almost none are long-context time series.
Prime Intellect RL resident @nzuma0 built one. AnomalyXL is an infinitely scalable synthetic generator with programmatic ground truth, written in verifiers.
He then trained a 4B TimeRLM on it with prime-rl, generating fresh data every step, with the model recursively calling sub-agents via nano-rlm to localize anomalies across 131k datapoints. It transfers zero-shot to ECG, sleep and observability data.
