Back to Chat with your data README

Supporting documentation

Overview

Chat with Your Data uses Azure AI Foundry model deployments (a chat model, a reasoning model, and an embedding model) as its single inference surface. The backend calls Foundry with the workload's managed identity, so there are no model API keys to store. This guide lists the settings that control which models are deployed and how they are sized.

Available models

For the models and versions available in each region, see the Azure AI Foundry models documentation.

Default deployments

Chat model parameters

ParameterExamplePurpose
AZURE_GPT_MODEL_NAMEgpt-5.4-miniChat model name.
AZURE_GPT_MODEL_VERSION2026-03-17Chat model version.
AZURE_GPT_MODEL_DEPLOYMENT_TYPEGlobalStandardChat model deployment type.
AZURE_GPT_MODEL_CAPACITY50Tokens-per-minute limit (thousands).

Reasoning model parameters

ParameterExamplePurpose
AZURE_REASONING_MODEL_NAMEgpt-5-miniReasoning model name.
AZURE_REASONING_MODEL_VERSION2025-08-07Reasoning model version.
AZURE_REASONING_MODEL_DEPLOYMENT_TYPEGlobalStandardReasoning model deployment type.
AZURE_REASONING_MODEL_CAPACITY50Tokens-per-minute limit (thousands).

Embedding model parameters

ParameterExamplePurpose
AZURE_EMBEDDING_MODEL_NAMEtext-embedding-3-smallEmbedding model name.
AZURE_EMBEDDING_MODEL_VERSION1Embedding model version.
AZURE_EMBEDDING_MODEL_DEPLOYMENT_TYPEStandardEmbedding model deployment type.
AZURE_EMBEDDING_MODEL_CAPACITY100Tokens-per-minute limit (thousands).

The embedding model sets the vector dimensions written to the retrieval index. text-embedding-3-small produces 1536-dimensional vectors. In PostgreSQL mode, the vector column width is set from this dimension when the index is first created; see PostgreSQL.

API version parameters

ParameterExamplePurpose
AZURE_OPENAI_API_VERSION2025-01-01-previewAPI version for chat and embedding calls.
AZURE_AI_AGENT_API_VERSION2025-05-01API version for the Foundry agent runtime.

Set and read parameters

Set a parameter before azd up:

azd env set <NAME> <VALUE>

Read the current values for your environment:

azd env get-values
