DeepSeek Deepseek R1 Zero (deepseek/deepseek-r1-zero) — Automatic Disk KV Cache (0.05/1M) & Off-Peak Promo
DeepSeek-V4 Pro (1.6T MoE) automatically caches repeated 64-token prompt prefixes on NVMe storage at $0.022/1M off-peak input tokens (vs $0.66 off-peak base) with zero code changes required, plus off-peak UTC scheduling discounts.
xAI Grok 4.7 (grok-4.7) 2026 Q4 Developer Promotion & Volume Credits
Official 2026 Q4 promotion for xAI Grok 4.7: Activate ephemeral prefix caching to slash input costs by 75% (down to 0.5/1M) or route via asynchronous Batch API for 50% off standard token rates.
In Etuki October 2026 FinOps telemetry comparing DeepSeek Deepseek R1 Zero (API ID: deepseek/deepseek-r1-zero) vs xAI Grok 4.7 (API ID: grok-4.7), DeepSeek Deepseek R1 Zero offers lower standard input pricing at $0.5/1M tokens ($2/1M output), while DeepSeek Deepseek R1 Zero leads in cached prefix economics at $0.05/1M tokens (90% discount). xAI Grok 4.7 achieves a 65ms faster P90 time-to-first-token latency (130ms vs 195ms).
Gateway-synced rate ($0.5/$2 per 1M, flat 128K window). Verify upstream provider cache TTL and regional routing before high-volume batch runs.
<200K: $2.00/$6.00 ($0.50 cache); >=200K (including cached tokens) full-request 2x cliff: $4.00/$12.00 ($1.00 cache). Not eligible for Batch discount (0%); Priority 2x; US endpoint +10%.
