Luna Offers Cheaper Inputs, but DeepSeek Wins Cache Economics in Long Agentic Sessions
teortaxesTex · x · 2026-07-31
A developer has shared a detailed pricing comparison between Luna and DeepSeek. While Luna wins on extremely cheap input tokens, its output token price ($1.20) is significantly higher than DeepSeek's ($0.28).
In long agentic sessions involving hundreds of tool calls, Luna's cache economics will start to bite and accumulate costs. Even before hitting the 272K context limit, DeepSeek remains on the frontier due to its overall cost-effectiveness.
