Quick answer:<\/strong> GPT-6 Astra costs $10 per 1M input tokens<\/strong>, $1 per 1M cached input tokens<\/strong>, $12.50 per 1M cache-write tokens<\/strong>, and $50 per 1M output tokens<\/strong> at Standard rates while a prompt stays at or below 272K input tokens. Above 272K, the full request moves to long-context pricing: $20 input, $2 cached input, $25 cache writes, and $75 output per 1M tokens. OpenAI documents a 1.05M-token context window and a 128K maximum output.<\/p>\n\n\n\n

Those numbers make Astra powerful but expensive enough to require planning. A repeated prompt can become much cheaper when caching works, while a request that barely crosses 272K input tokens can become sharply more expensive. This guide separates official prices from calculated examples and from our September 5, 2026 hands-on API observations.<\/p>\n\n\n\n
