Ideal for production workloads demanding flagship capabilities, deep context depth (1.05M tokens), and reliability from OpenAI. Excellent when predictable tokenomics and prompt caching support are paramount.
If your use-case requires sub-second streaming latency or ultra-high frequency classification at micro-cent pricing, consider lighter budget options such as Gemini Flash-Lite or Claude Haiku. For deep formal logic, consider dedicated reasoning models like o3.
For GPT-6 Astra, 1 million input tokens costs $10.00, while 1 million output tokens costs $50.00. If using prompt caching, repetitive input prefixes are discounted to $1.00 per million.
GPT-6 Astra features a maximum context window of 1,050,000 tokens (~787,500 words), with a maximum output limit of 32,768 tokens per completion.
GPT-6 Astra utilizes the OpenAI o200k_base (200k vocabulary). Token counting on TokenMath runs client-side to ensure maximum privacy.
Yes. GPT-6 Astra supports prompt caching with a cached input rate of $1.00/1M (saving up to 90% on repeated input context).
