# LLM Configuration:
# Agent templates support multiple flexible LLM options including:
# - LLM Gateway Direct (default)
# - LLM Blueprint with an External LLM
# - Already Deployed Text Generation model in DataRobot
#
# You can edit the LLM configuration by manually changing which configuration is
# active (recommended option).
# Simply run `ln -sf ../configurations/llm/<chosen_configuration>.py`
# from the `infra/infra` folder
#
# If you want to do it dynamically however, you can also set it as a configuration value with:
# INFRA_ENABLE_LLM=<chosen_configuration>
# from the list of options in the infra/configurations/llm folder
# Here are some examples of each of those configuration using the dynamic option described above:

# If you want to use the LLM Gateway direct (default)
# INFRA_ENABLE_LLM=gateway_direct.py

# If you want to choose an existing LLM Deployment in DataRobot
# uncomment and configure these:
# TEXTGEN_DEPLOYMENT_ID=<your_deployment_id>
# INFRA_ENABLE_LLM=deployed_llm.py

# If you want to configure an LLM with an external LLM provider
# like Azure, Bedrock, Anthropic, or VertexAI (or all 4). Here we provide
# an Azure AI example, see:
# https://docs.datarobot.com/en/docs/gen-ai/playground-tools/deploy-llm.html
