An integer between $1000$ and $9999,$ inclusive, is called balanced if the sum of its two leftmost digits equals the sum of its two rightmost digits. How many balanced integers are there? Let's think step by step and output the final answer within \boxed{}.<|im_end|>

Okay, so I need to figure out how many four-digit numbers are "balanced." A balanced integer is one where the sum of the first two digits equals the sum of the last two digits. Let me break this down.

dpo_uid_mix
Historical AIME response data generated with Qwen3-1.7B for the UID comparison pipeline.
Train: 413 rows. Dev: 53 rows.
Both chosen and rejected responses are verifier-correct, complete, untruncated, and UID-eligible.
The response with the highest q_UID is chosen; the response with the lowest q_UID is rejected.
All four DPO variants use the same prompts. Each prompt must have at least two distinct responses and a score gap of at least 0.05 for all three scores (q_SC, q_UID, uid_product). Each qualifying prompt contributes one pair.
Columns: prompt, chosen, rejected, prompt_id, chosen_id, rejected_id.
The original local variant name is dpo_uid_mix. manifest.json records the shared build settings and counts across all eight variants.
