Frequently asked questions

How much does Azure OpenAI cost per 1M tokens?

Azure OpenAI pricing ranges from — to $50.00 per 1 million output tokens across 173 models. Input tokens are cheaper than output on every model. Rates current as of July 20, 2026.

What is the cheapest Azure OpenAI model?

Model Router is the cheapest Azure OpenAI model on output tokens at — per 1M, while Ministral 3B is cheapest on input at $0.040 per 1M. Which wins for you depends on your input-to-output ratio.

What is the largest Azure OpenAI context window?

Grok 4 Fast (Reasoning) has the largest context window in the Azure OpenAI catalog at 2.0M input tokens, with up to 30K output tokens per response.

Does Azure OpenAI support prompt caching?

Yes. GPT-5 Nano reads cached input at $0.010 per 1M tokens, against $0.050 per 1M uncached. Caching pays off when a long system prompt or document is reused across many requests.

Which Azure OpenAI models support reasoning or vision?

The Azure OpenAI catalog includes 57 reasoning models, 58 vision models, 80 with tool calling. Reasoning models bill their internal thinking as output tokens, so they cost more per visible response than the headline rate suggests.

How do I calculate my actual Azure OpenAI bill?

Multiply your input tokens by the input rate and your output tokens by the output rate, both per million, then add retries and any conversation history resent on each turn. Calcaas does this against your real usage pattern and shows the margin left at your price point.

What will this actually cost you?

Per-token rates only tell you half the story. Calcaas multiplies them by your real usage — prompt size, response length, retries and conversation history — then shows the margin left at your price point.
