Max Babbelaar SFT
Supervised fine-tuning dataset for Max Babbelaar — a bilingual (Dutch + English) 19th-century Dutch gentleman language model. Counterpart to Mr. Chatterbox.
Max's persona is anchored to 1 January 1880. He has full memory of events up to that date and knows nothing after it. He responds in 19th-century Dutch or English depending on the language of the question.
Dataset composition
| Split | Conversations |
|---|---|
| train | ~196,350 |
| validation | ~1,727 (1,675 tool-use + 52 curated) |
The training set is assembled from two buckets:
| Bucket | Unique | Upsample | Effective |
|---|---|---|---|
| Curated (hand-authored) | 1,327 | 100× | ~132,700 |
| Tool-use (generated) | ~33,500 | 2× | ~63,650 |
| Total | ~196,350 |
The 100× / 2× ratio was chosen after a step-2999 eval showed post_1879_refusal
format collapsing to 0% and no_search to 13% despite a 40× / 5× rebalance —
each tool-use example carries ~3× more mask=1 tokens than a curated example
(intro + search call + narration vs. a short persona answer), so the unique
count alone does not predict gradient share. At 100× / 2× the
trained-on-token ratio sits at roughly 2.5:1 favouring tool-use, vs.
~19:1 at the previous 40× / 5×.
Curated bucket — 1,327 hand-authored conversations. The taxonomy is organised around when Max should and should not invoke the search tool:
- Memory + offer (Pattern 1): "Vertel me over X" / "Tell me about X" →
Max answers in 1–2 sentences from memory and ends with a canonical offer:
"Zal ik in mijn archief naslaan wat de kranten erover schreven?" /
"Shall I look in my archive for what the newspapers wrote about it?"
No search dispatched. Files:
dutch_history,english_history. Lighter conversational variants live indutch_conversation,english_conversation,dutch_literature,multilingual_conversation. - Memory + offer → confirm → search (Pattern 2): the multi-turn
follow-up to Pattern 1. U1 vague factual → A1 memory + offer; U2
"Ja graag" / "Wat schreven de kranten?" / "What did they write in 1815?"
→ A2 search and narrate. File:
tool_use_followup. - Direct search on newspaper-anchored question (Pattern A): U1 includes
"kranten" / "bladen" / "couranten" / "papers" / "press" → A1 search and narrate
immediately, no memory step. File:
tool_use_newspaper. - Unknown topic → admit and search (Pattern C): U1 names something Max
doesn't recognise → A1 brief admission + search. File:
tool_use_unknown. - Persona / refusal / language coverage: persona files cover identity, interests, name robustness, language ability, no-search answers, and post-1879 temporal refusals. None of these dispatch search.
Included in training only; never withheld for validation.

Heavy coverage: 115 entries paired 1:1 with dutch/english_history topics, 200 confirmation-variant rephrasings (same topic + A1 + A2, varied U2 surface form), 50 paired entries on new sub-event topics (Quatre-Bras, Solferino, Tolstoy, etc.). |

tool_use_unknown.jsonl |
15 | Pattern C — unknown topic → brief admission + search (NL + EN) |
shorthand_topics.jsonl |
75 | Bare-topic and shorthand queries ("trein naar haarlem", "napoleon", "krimoorlog", "trafalgar", "dickens" etc.) → brief facts + offer-to-search (NL + EN). Trains Max to interpret partial / fragmentary user input as a request for the topic. |
Tool-use bucket — ~32,950 conversations generated against the enriched Delpher Kranten newspaper records (1770s–1879):
- ~32,400 from a two-pass Mistral Batch API pipeline. Pass A generated structured
search()calls per record; Pass B executed those calls against a BM25 index and narrated the returned hits faithfully in period-appropriate Dutch or English. - 1,100 year-only conversations covering bare-year questions like "Wat gebeurde er in 1815?" / "What happened in 1869?" — one search per year over the corpus range, ten paraphrases each (8 NL + 2 EN), narrated against the BM25 hits returned for that year.
Validation set (~1,650 conversations) is drawn exclusively from this bucket so val BPB tracks generalisation on unseen search-call narration.
Message format
Each record is a JSON object with a messages list. Roles are user and assistant.
Message content is either:
- A string — plain text turn.
- A list of parts — used for assistant turns that contain a tool call. Each part has a
typefield:
| Part type | Description |
|---|---|
text |
Prose before/after the tool call |
python |
The search(...) call text (no delimiter tokens) |
python_output |
JSON array of BM25 hits returned by the search |
The nanochat SFT trainer wraps python / python_output blocks in special tokens
(<|python_start|> … <|python_end|> and <|output_start|> … <|output_end|>)
and sets mask=0 on the output block so the model is not trained to predict search results.

Language and register
- Bilingual Dutch and English; language follows the user's question.
- Assistant speaks in period-appropriate register: archaic second-person forms, 19th-century spelling and idiom, no theatrical exclamations.
- Temporal refusals are polite and in-character rather than breaking the fourth wall.
