Azure OpenAI pricing questions
How much does the Azure OpenAI cost?

On 2026-10-25, standard prices ran from $0.20 (GPT-5.6-luna) to $10.00 (GPT-6 Astra) per 1M input tokens, and $1.20 (GPT-5.6-luna) to $50.00 (GPT-6 Astra) per 1M output tokens. Speech to text runs from $0.27 (GPT-Transcribe) to $0.396 (Whisper) per hour. Text to speech runs from $15.00 (TTS (Text to Speech)) to $33.00 (TTS HD) per 1M characters. Embeddings runs from $0.022 (text-embedding-3-small) to $0.143 (text-embedding-3-large) per 1M tokens. Image generation runs from $0.044 per image.
Does Microsoft Azure offer a batch discount?
On some models. Batch API prices are listed for GPT-5.4, GPT-5.4 mini. The price table shows which rows have one.
Where do these prices come from?
From Microsoft Azure's own pricing page, https://azure.microsoft.com/en-us/pricing/details/cognitive-services/openai-service/, checked on 2026-10-25. Every row links to it. When a price cannot be confirmed, the row says to check the vendor's page instead of showing a number.
Why are GPT-6 Sol and GPT-6 Luna not in the table?
On 2026-10-25 Microsoft's page said their prices were still being processed for publishing. We list a price only once the vendor's page shows it.
