How Much Does GPT-6 Astra Cost? Quick Answer GPT-6 Astra is available at $10 per 1M input tokens, $50 per 1M output tokens, and $1 per 1M cached input tokens, according to OpenAI's model documentation. Cache writes cost $12.50 per 1M tokens. Requests with more than 272K input tokens are priced at 2× input and cache rates and 1.5× output rates for the full request. Very large-context requests can therefore reach $20 per 1M input tokens and $75 per 1M output tokens. ZenMux provides GPT-6 Astra through our unified API alongside models from Anthropic, Google, DeepSeek, and other providers. Because token volume, cache performance, latency, and throughput change over time, check the GPT-6 Astra model page on ZenMux for current routing metrics and pricing. For teams using ZenMux, the practical cost question is not only "What does GPT-6 Astra cost?" but also "Which requests need Astra, and which can be routed to a lower-cost model available on ZenMux?" GPT-6 Astra API Pricing Explained: Input, Output, Cache Writes & Cached Tokens GPT-6 Astra charges $10 per 1M input tokens, $50 per 1M output tokens, and $1 per 1M cached input tokens under standard API pricing. Cache writes cost $12.50 per 1M tokens, or 1.25× the uncached input-token rate. Four token types determine API usage costs: — text, images, or structured data sent in the prompt to the model — text the model generates in its response, including billed reasoning tokens where applicable
