When to Choose Azure OpenAI
Cost-sensitive workloads
Use GPT-4o mini (Azure) — Azure OpenAI's most affordable model at $0.15/M input / $0.60/M output. Estimated cost at 100K requests/month: $45.00.
Complex or high-accuracy tasks
Use o3 (Azure) — Azure OpenAI's most capable model (reasoning tier) with a 200,000-token context window. Priced at $2.00/M input / $8.00/M output.
High-volume pipelines
Azure OpenAI models are well-suited for high-throughput workloads. Consider batch API (where supported) for an additional 50% cost reduction on asynchronous pipelines. Check the pricing table above for batch pricing availability.

Frequently Asked Questions: Azure OpenAI API Pricing
What is the cheapest Azure OpenAI model?
The cheapest Azure OpenAI model by input token price is GPT-4o mini (Azure), priced at $0.15/M for input tokens and $0.60/M for output tokens. It is best suited for high-volume, cost-sensitive workloads where speed and price matter most.
What is the most capable Azure OpenAI model?
o3 (Azure) is Azure OpenAI's most capable model, classified as a reasoning-tier model. It supports a context window of 200,000 tokens and is priced at $2.00/M input / $8.00/M output per million tokens.
How does Azure OpenAI API pricing work?
Azure OpenAI charges per token consumed — separately for input tokens (the text you send) and output tokens (the text the model generates). Prices are listed in USD per 1 million tokens ($/M). Azure OpenAI was founded in 2023 and is headquartered in Redmond, WA. All pricing shown here is sourced from the official Azure OpenAI pricing page.
Does Azure OpenAI offer batch API pricing?
Azure OpenAI's current model lineup does not include batch API pricing at this time. For cost reduction on high-volume workloads, consider prompt caching (where supported) or running multiple concurrent requests with standard pricing.
Which Azure OpenAI models support vision / image inputs?
6 Azure OpenAI models support vision (image input): GPT-4o (Azure), GPT-4o mini (Azure), GPT-5.2 (Azure), GPT-5.1 (Azure), o3 (Azure), o4-mini (Azure). These models can analyze images, charts, screenshots, and documents alongside text prompts.
