Inception: Mercury 3 (inception/mercury-3) 2026 Q4 Developer Promotion & Volume Credits
Official 2026 Q4 promotion for Inception: Mercury 3: Activate ephemeral prefix caching to slash input costs by 50% (down to 0.05/1M) or route via asynchronous Batch API for 50% off standard token rates.
In Etuki October 2026 FinOps telemetry comparing Nous DeepHermes 3 8B (API ID: nousresearch/deephermes-3-llama-3-8b-preview) vs Inception: Mercury 3 (API ID: inception/mercury-3), Nous DeepHermes 3 8B offers lower standard input pricing at $0.04/1M tokens ($0.08/1M output), while Nous DeepHermes 3 8B leads in cached prefix economics at $0.004/1M tokens (90% discount). Nous DeepHermes 3 8B achieves a 135ms faster P90 time-to-first-token latency (145ms vs 280ms).
⚠️ 272K Context Cliff: Standard $2.00/$10.00 (Cache $0.10) applies up to ≤272K tokens. Prompts exceeding >272K tokens jump to $4.00 input / $15.00 output per 1M tokens.
