How we calculate it
GPT-5.6 Sol chat: 1,800 msgs × $0.0372 = $67; GPT-6 Pro (Astra prices $10/$1/$50): ~150 msgs/mo (70% of 50/wk) × (20K in 50% cached, 15K out) × $0.86 = $129. Codex/Work: 5x × $700 theoretical max = $3,500, we take 20% = $700 (~3,200 GPT-6.1 Sol turns). Deep Research 30 × $3 = $90; 400 images × $0.10 = $40; voice 600 min × $0.05 = $30. Dots not counted.
ROI = (API value − price) / price = ($1,056 − $100) / $100 = 956%.
