🚀 What’s New?

The protein-shake sequel to MasterControlAIML/DeepSeek-R1-Qwen2.5-1.5b-SFT-R1-JSON-Unstructured-To-Structured—now with more neurons, zero SFT, and a league of reward functions.

---

🛠️ Intended Use

• Convert messy prose, logs, or audit notes into a pristine JSON document that follows a complex, nested schema.
• Drop-in replacement for any pipeline using the older DeepSeek-R1 1.5 B structurer—just swap the checkpoint and enjoy the headroom.

🔧 How to Use (Reasoning + JSON)

The snippet below:

1. Primes the model with the exact Pydantic schema, so it outputs the right keys.
2. Makes the model think step-by-step (reasoning) but still wraps the final JSON in an easy-to-parse container.
3. Uses the correct repo name: MasterControlAIML/DeepSeek-R1-Qwen2.5-3b-LLM-Judge-Reward-JSON-Unstructured-To-Structured-Lora.

    You are an expert **data-extraction assistant**.
    Extract structured info from unstructured text **exactly** following the Pydantic schema.

    ── Schema ──
    {SCHEMA_TEXT}
    ─────────────

    Rules:
      1. Follow the schema for keys & nesting.
      2. Copy values verbatim when possible.
      3. If a field is missing, return null.
      4. Output your step-by-step reasoning first.
      5. Then return ONLY the JSON inside this wrapper:
         final answer[ json object: {{ ... }} ]

    Format:
      <reasoning>…</reasoning>
      <answer>
      final answer[ json object: {{ … }} ]
      </answer>
""").strip()

UNSTRUCTURED_TEXT = """

# 3️⃣  Generate ───────────────────────────────────────────────────────────────
tok   = AutoTokenizer.from_pretrained(MODEL, use_fast=True)
model = AutoModelForCausalLM.from_pretrained(
    MODEL,

    torch_dtype=torch.bfloat16
)
gen = pipeline("text-generation", model=model, tokenizer=tok,
               max_new_tokens=512, do_sample=False)

prompt = f"<|system|>\n{SYSTEM_PROMPT}\n<|user|>\n{USER_PROMPT}"
raw_out = gen(prompt)[0]["generated_text"]

# 4️⃣  Slice out the JSON ─────────────────────────────────────────────────────
start = raw_out.find("final answer[")
end   = raw_out.rfind("]") + 1
json_text = raw_out[start:].split("json object:")[-1].strip(" []\n")
data = json.loads(json_text)    # ✅ Raises if malformed

print(raw_out)  # reasoning + JSON
print("\n✅ Parsed object:\n", data)

Why it Works 🧐

• Schema-priming ensures key-level fidelity—no “creative” field names.
• Chain-of-thought improves factual extraction (was rewarded during GRPO).
• The final answer[…] wrapper makes downstream parsing a one-liner.
