Parason: Subtask- and Trial-Parallel Reasoning Data
Training data for Parason, which turns long sequential reasoning traces into executable parallel programs. Three subsets, one per training stage.
| Subfolder | Stage | Contents |
|---|---|---|
sft-8x |
SFT (main) | Parallel trajectories with <Subtask> / <Trial> branches, Trial stages expanded 8x — extra branches sampled with Qwen3-8B, their <Trial> goals written by Gemini-3-Flash |
sft-1x |
SFT (baseline) | The unexpanded parallel trajectories: 964 annotated Qwen3-8B traces released by ThreadWeaver, each parallel stage labeled Subtask or Trial by Gemini-3-Flash |
rl |
PA-GRPO | RL prompt set — Polaris-53k (~53,000 complex reasoning problems), used unmodified |
Each subfolder holds a single train.parquet; there is no validation split. The two SFT sets are
matched in effective token budget (8 epochs over sft-1x ≈ 1 epoch over sft-8x).
Trajectory format
The SFT trajectories mark two distinct forms of parallelism:
<Subtask>— AND-branches. The problem splits into independent sub-goals, each producing a required result. Shortens the critical path.<Trial>— OR-branches. Competing speculative attempts test different hypotheses; all outputs are concatenated back into the reasoning history. Widens search.
