COST-ANALYSIS

DeepSeek V4 economics for agentic coding: worked cost math, the Flash vs Pro split, and when to route coding work to DeepSeek instead of a frontier model.

Self-hosting open-weights models like GLM-5.2, DeepSeek V4 or Llama: the break-even math against per-token API prices, with GPU costs and the hidden ops bill.

Claude Fable 5 pricing beyond the $10/$50 per MTok list rate: real cost per task versus Opus 5, Opus 4.8 and Sonnet 5, and when the premium pays off.

Fable 5 vs DeepSeek V4 on cost and quality: a 178x output price gap, a real quality difference, and the task split most production teams end up running.
