Docs FAQ: 'Fast mode for GPT-6 Astra does not include a latency SLA. For GPT-5.6 and earlier models, Fast mode and Scale Tier receive the same service-level agreement treatment, and eligible Enterprise agreements may provide service credits when latency targets aren't met.' No numbers are stated on the Fast mode page itself, so tiers is empty (the Scale Tier numbers may apply by reference but that is not stated explicitly).
