GPT-6 Astra API Pricing: Cost Calculator & Real Examples (2026)
GPT-6 Astra charges $10.00 per 1 million input tokens and $50.00 per 1 million output tokens. But per-token prices don't answer the real question: what will your workload cost per month? Below we compute it for three realistic scenarios — or run your own numbers with GPT-6 Astra preselected.
| Meter | Price per 1M tokens |
|---|---|
| Input | $10.00 |
| Cached input | $1.00 |
| Output | $50.00 |
Note: Standard short-context pricing. Long-context and Fast mode requests use different rates.
What does GPT-6 Astra cost in practice?
| Monthly scenario | Token bill |
|---|---|
| Support chatbot (150k requests, 400 in / 300 out tokens) | $2,850.00 |
| Document workflow (22k runs, 3,000 in / 400 out tokens) | $1,100.00 |
| High-volume classifier (1M requests, 300 in / 10 out tokens) | $3,500.00 |
In the chatbot scenario, output is ~79% of the GPT-6 Astra bill — capping response length (max tokens) is the most direct optimization. Document workflows are input-heavy, so the input rate dominates there.
Prompt caching savings
GPT-6 Astra offers cached input at $1.00/1M (vs $10.00 standard). At a 60% cache-hit rate, the example chatbot drops from $2,850.00 to $2,526.00/month — saving $324.00. If your system prompt and context are stable, this discount is free money.
Is GPT-6 Astra cheap or expensive?
On the same chatbot workload, GPT-6 Astra is cheaper than 0 of the 11 models we track (position 12 of 12, cheapest to priciest). The nearest cheaper alternative is Claude Opus 4.8 ($1,425.00/month on the same scenario). The right decision isn't absolute price but the cheapest model that meets your quality bar — test before overpaying.

Our take on this model
Astra is OpenAI's highest-priced general flagship in the current standard API table. Its budget case is not routine chat; it is difficult, multi-step work where better reasoning can prevent an expensive retry, escalation or human review cycle.
Astra costs 2.5× as much as Sol for both uncached input and output at standard short-context rates. Route only the requests that fail a measured quality threshold to Astra, and keep a cheaper model as the default.
