Supported Models
AI Assistant can be configured to use different LLM models. This page lists the models that have been validated for compatibility with AI Assistant.
Model validation focuses on whether the model can successfully support the capabilities required by AI Assistant, including tool calling and interaction with Release data.
AI Assistant does not maintain model-specific answers. The same AI Assistant instructions, tools, and underlying Release data are used across supported models. However, the wording, reasoning, and quality of responses may vary between models.
Supported Models
These models have been tested and are supported.
| Provider | Model | AI_LLM_CHAT_MODEL |
|---|---|---|
| Anthropic | Claude Sonnet 4.6 | claude-sonnet-4-6 |
| Anthropic | Claude Sonnet 5 | claude-sonnet-5 |
| Anthropic | Claude Opus 5 | claude-opus-5 |
| OpenAI | GPT-4o | gpt-4o |
| OpenAI | GPT-5.5 | gpt-5.5 |
| OpenAI | GPT-5.4 mini | gpt-5.4-mini |
Set AI_LLM_CHAT_MODEL to the model name shown in the table.
Use the bare model name. Provider-prefixed values, such as anthropic.claude-sonnet-4-6, are not
supported by the local LLM Service.
What "Supported" means
A supported model has been validated to work with the AI Assistant workflows and the LLM integration used by the product.
Support indicates compatibility, not identical response output across models. Different models may produce different wording, levels of detail, or reasoning for the same question.
Unsupported Models
The following models have been tested and are known to be incompatible with the current AI Assistant implementation.
| Provider | Model | Issue |
|---|---|---|
| OpenAI | GPT-5.6 Terra | Tool calling is not supported on the endpoint used by AI Assistant |
| OpenAI | GPT-5.6 Sol | Tool calling is not supported on the endpoint used by AI Assistant |
| OpenAI | GPT-5.6 Luna | Tool calling is not supported on the endpoint used by AI Assistant |
Do not use the models listed above. AI Assistant relies on tool calls to retrieve and query Release data. These models reject the required tool calls on the endpoint currently used by AI Assistant and therefore cannot complete AI Assistant workflows correctly.
Other Models
Any model not listed above has not been validated with AI Assistant.
An unvalidated model may work, but compatibility and response quality have not been verified. Before using an unvalidated model in production, test it in a Lab Deployment Using Docker, including scenarios that require AI Assistant to query Release data through tool calls.
