Fable-5-traces

Glint Research Dataset Card Fable 5 Pi Agent Traces A compact, high-signal corpus of Fable 5 coding-agent traces converted into Hugging Face Agent Traces / Pi-compatible sessions for Data Studio inspection, tool-use policy learning, and reasoning/action distillation. Primary Config pi_agent/train Agent Trace preview enabled 4,665 Pi trace sessions 60 source sessions 3,799 tool actions 866 assistant text actions AGPL-3.0 Rows 4,665 one converted Pi trace per merged row Tool Calls 81.44% Bash, Edit, Read, Write, browser/preview tools Reasoning Median 2,365 median characters in cot Model Fable 5 all rows report claude-fable-5 Overview `Glint-Research/Fable-5-traces` preserves Fable 5 coding-agent behavior in two complementary surfaces: | Surface | Location | Purpose | |:--|:--|:--| | Agent Trace view | `pi-traces/*.jsonl` through config `pi_agent/train` | Hugging Face Agent Traces / Data Studio inspection. Each file is a Pi-style trace containing a `session`, `model_change`, `thinking_level_change`, user context, and assistant reasoning plus text/tool output. | | Merged training rows | `fable5_cot_merged.jsonl` | Flat JSONL for direct SFT, filtering, and custom conversion. Each row contains `context`, `cot`, `output_type`, `output`, `completion`, and provenance fields. | | Raw logs | `/claude/` | Original session-level material retained for archival inspection and alternative converters. | The active dataset viewer is intentionally pointed at the Pi trace files so the Hub can render the examples as agent trajectories rather than as a plain JSONL table. Dataset Anatomy The merged row corpus was audited on June 19, 2026. Counts below are computed over `fable5_cot_merged.jsonl` and the generated `pi-traces/` conversion. | Metric | Value | |:--|--:| | Total merged examples | 4,665 | | Pi trace files | 4,665 | | Unique source sessions | 60 | | Model rows | 4,665 `claude-fable-5` | | Tool-use rows | 3,799 | | Assistant text rows | 866 | | Local-origin rows | 3,712 | | Import
