DeepSeek-V4 Pro vs Meta: Muse Spark 1.3: Live Promos, Pricing, Hidden Fees & Latency
Verified 2026 FinOps benchmark comparing DeepSeek-V4 Pro (deepseek-v4-pro) vs Meta: Muse Spark 1.3 (meta/muse-spark-1.3). Simulate cache read multipliers, context cliffs, MAU bills, and P90 latency.
Zero-Config Disk KV Cache ($0.07/1M) & Off-Peak UTC Batch Arbitrage
DeepSeek-V4 Pro (1.6T MoE) automatically caches repeated 64-token prompt prefixes on NVMe storage at $0.07/1M input tokens (50% off $0.14 base) with zero code changes required, plus off-peak UTC scheduling discounts.
Meta: Muse Spark 1.3 (meta/muse-spark-1.3) 2026 Q4 Developer Promotion & Volume Credits
Official 2026 Q4 promotion for Meta: Muse Spark 1.3: Activate ephemeral prefix caching to slash input costs by 50% (down to $0.625/1M) or route via asynchronous Batch API for 50% off standard token rates.
In Etuki October 2026 FinOps telemetry comparing DeepSeek-V4 Pro (API ID: deepseek-v4-pro) vs Meta: Muse Spark 1.3 (API ID: meta/muse-spark-1.3), DeepSeek-V4 Pro offers lower standard input pricing at $0.14/1M tokens ($0.28/1M output), while DeepSeek-V4 Pro leads in cached prefix economics at $0.07/1M tokens (50% discount). Meta: Muse Spark 1.3 achieves a 180ms faster P90 time-to-first-token latency (280ms vs 460ms).
Enable Prompt Context Caching & Batch API to reduce repeated system prompt input token burn by 50%-97.5%.
