Speed tax compared: Astra Ultrafast at $60/$300 per 1M tokens
A price breakdown shows GPT-6 Astra at $10/$50 standard, $20/$100 Fast, and $60/$300 Ultrafast, a 6x multiplier for speed, compared with GPT-6.1 Sol and Claude Opus 5.5 fast modes.
OpenAI and Anthropic are no longer just charging you for intelligence, they’re charging a massive multiplier for speed. Here is the current "Speed Tax" per 1M tokens (Input / Output): • GPT-6 Astra: Standard ($10 / $50) → Fast ($20 / $100) → Ultrafast ($60 / $300) [6× price] • GPT-6.1 Sol: Standard ($2 / $10) → Fast ($4 / $20) → Ultrafast ($12 / $60) [6× price for 8× speed] • Claude Opus 5.5: Standard ($4 / $20) → Fast Mode ($8 / $40) [2× price for 2.5× speed] Paying $300/1M output tokens on Astra Ultrafast is brutal. Is 8× speed worth 6× the bill?
