# Submit CT LLM Gemini jobs SEQUENTIALLY to avoid 250 RPD contention.
#
# The free tier only allows 250 requests/day. Running 16 jobs concurrently
# means each gets ~15 RPD (useless). Sequential gives each job the full
# 250 RPD quota. The benchmark script auto-resumes from existing predictions.
#
# Order: smallest tasks first (L3=160 → L4=400 → L2=400 → L1=900)
# Expected timeline at 250 RPD: ~30 days total
#
# Usage:
#   bash slurm/submit_ct_gemini_sequential.sh [--dry-run]
