pinktilde32

A chat / instruct model specialized for retrieval-augmented generation (RAG), summarization, information extraction, and structured Markdown output, fine-tuned from TildeAI/TildeOpen-30b-64k — a 30B European multilingual base model with a 64k context window (extended via YaRN). Focus languages: German + English.

Intended use

  • Answering questions strictly from a provided context (RAG), with source citations [n].
  • Honest refusal when the answer is not in the context (no hallucination).
  • Summarization and information extraction from long inputs.
  • Structured output in Markdown (headings, bullet lists, tables).

Not intended for: code generation, free-standing factual answers without context, clinical/legal advice.

Prompt format

The model uses chatml (<|im_start|> / <|im_end|>). Recommended system prompt (the RAG contract):

Answer the question or extract the information STRICTLY from the provided context.
Cite the sources you use as [n]. Present the answer in clear Markdown structure.
If the information is not in the context, say so honestly and do not guess.

Example

import torch
from transformers import AutoModelForCausalLM, AutoTokenizer

model_id = "Bogula/pinktilde32"
tok = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(model_id, dtype=torch.bfloat16, device_map="auto")

system = ("Answer strictly from the context. Cite sources as [n]. Use Markdown. "
          "If the info is missing, say so honestly.")
context = "[1] Muster AG reported revenue of EUR 142M in 2025.\n[2] ..."
messages = [
    {"role": "system", "content": system},
    {"role": "user", "content": f"Context:\n{context}\n\nQuestion: What was the 2025 revenue?"},
]
inputs = tok.apply_chat_template(messages, add_generation_prompt=True,
                                 return_tensors="pt", return_dict=True).to(model.device)
out = model.generate(**inputs, max_new_tokens=512, temperature=0.3,
                     eos_token_id=tok.convert_tokens_to_ids("<|im_end|>"))
print(tok.decode(out[0][inputs["input_ids"].shape[1]:], skip_special_tokens=True))

Training

  • Method: LoRA SFT (all linear layers + embed_tokens/lm_head), then merged into the base model.
  • Training context length: 32k (sequence_len=32768, sample packing).
  • Format: chatml; loss computed on assistant turns only.

Data mix

Source Language Purpose
nvidia/Nemotron-Instruction-Following-Chat-v1 EN Instruction / format adherence, structured outputs
DiscoResearch/germanrag DE RAG grounding with citations + "unanswerable" cases
abisee/cnn_dailymail EN Summarization (Markdown)
wikimedia/wikipedia (de, business/psychology) DE Summarization (Markdown)
Internal company dialogues DE Domain / style anchor

Limitations

  • Long context: The target behaviors (grounding, formatting) were trained up to ~32k. For inputs between 32k and 64k only the base long-context capability of TildeOpen applies, where reliability may degrade.
  • Language balance: The instruction-following data is English; German format adherence benefits from transfer but may lag behind English.
  • May still occasionally hallucinate or imperfectly follow formatting instructions. Verify outputs.
