Formula: GB processed = requests × KB ÷ 1,000,000. Starter $0: 1 GB then $4/GB, 10k scores then $2.50 per 1k, 14-day retention, $10 model credits. Pro $249/mo: 5 GB then $3/GB, 50k scores then $1.50 per 1k, 30-day retention then $0.50/GB/month up to 180 days (steady state ≈ GB × $0.50 × (days − 30) ÷ 30), $100 model credits. Model credits are not part of the observability bill unless ticked. Enterprise is custom (not computed).
Estimates only. Official list prices as of 2026-11-02 (Asia/Shanghai); the provider's pricing page prevails. Sources: Braintrust pricing
