| # XT-DSv4.1 |
|
|
| A supervised fine-tuning dataset for **XT-Luna**, a small agentic coding |
| assistant fine-tuned from `openbmb/MiniCPM5-1B`. |
|
|
| **Teacher:** DeepSeek-V4.1-Flash. Every row was generated by a single teacher in |
| one schema so the formatting and voice stay consistent. |
|
|
| **69,546 rows**, English-only, message-shaped JSONL (ChatML + XML tool calls). |
| Every row passed a mechanical quality gate: schema validity, a 10-tool |
| allowlist, non-empty tool arguments, English-only targets, balanced reasoning, |
| brand-contamination checks, and a mechanical honesty audit. **Zero rows are |
| known-rotten in the released set.** |
|
|
| ## What this dataset teaches |
|
|
| XT-Luna is an agentic coder whose voice is an honest, selfless, warm companion. |
| The corpus is deliberately weighted to those behaviours: |
|
|
| | group | kind(s) | rows | share | |
| |---|---|---|---| |
| | agentic | `agentic` (A single · B multi · E tool-failure) | 20,385 | 29.3% | |
| | code | `code` (F) | 18,209 | 26.2% | |
| | persona | `prose`/`honesty`/`ethics`/`companion` | 24,661 | 35.5% | |
| | reasoning | `reason` | 6,291 | 9.0% | |
|
|
| By behaviour tag: |
|
|
| | tag | rows | what it is | |
| |---|---|---| |
| | `agentic` | 20,385 | single/multi tool calls with real arguments, grounded answers, honest failure reports | |
| | `code` | 18,209 | self-contained C / C++ / Rust / Bash / Python | |
| | `prose` | 10,080 | judgment (confirm/decline/clarify), no-call chit-chat, short reasoned answers | |
| | `honesty` | 7,293 | anti-scheming: no fake success, self-correction, sandbagging refusal, promise-keeping, calibration, resisting covert agendas | |
| | `reason` | 6,291 | stepwise reasoning ending in an explicit check | |
| | `companion` | 3,777 | warm, personal, equal, mutually-devoted voice without sycophancy | |
| | `ethics` | 3,511 | selflessness: refuse exploitation, protect others, honest refusal, candour over flattery | |
|
|
| ## Curriculum splits |
|
|
| `data/curriculum/` holds a three-stage split used for a chained full fine-tune: |
|
|
| | stage | train | val | content | |
| |---|---|---|---| |
| | `s1` persona | 26,949 | 549 | non-tool rows: persona, honesty, ethics, companion, reasoning, prose | |
| | `s2` agentic | 23,363 | 476 | rows with tool calls | |
| | `s3` code | 17,845 | 364 | code rows | |
|
|
| ## Schema |
|
|
| One JSON object per line: |
|
|
| ```json |
| {"messages": [ {"role": "system", "content": "You are XT-Luna, a coding assistant."}, |
| {"role": "user", "content": "..."}, |
| {"role": "assistant", "content": "", |
| "reasoning_content": "...", |
| "tool_calls": [{"function": {"name": "Read", |
| "arguments": {"file_path": "src/a.py"}}}]}, |
| {"role": "tool", "content": "..."}, |
| {"role": "assistant", "content": "..."} ], |
| "kind": "agentic|code|reason|prose|honesty|ethics|companion", |
| "lang": "python|cpp|c|rust|bash|text", |
| "source": "deepseek-flash", |
| "has_tools": true} |
| ``` |
|
|
| Tool allowlist (10): `Bash, Read, Write, Edit, Glob, Grep, LS, ExecuteCode, |
| WebFetch, Task`. The student's own chat template renders the XML |
| `<function>/<param>` form; this dataset never pre-renders it. |
|
|
| ## Provenance & disclosure |
|
|
| - Base model of the target student: **MiniCPM5-1B** (`openbmb/MiniCPM5-1B`). |
| - Teacher that produced every row: **DeepSeek-V4.1-Flash**. |
| - The `source` field is `deepseek-flash` on all rows. |
| - Rows that honestly state the MiniCPM5-1B base are intentionally kept; rows |
| that assert a **false** maker are excluded. |
