Image Generator object is a tool to handle image generation. If the image generator object instance exists, an Agent can configure it as a tool and utilize to generate images.
Nova Canvas, the only image model available to Image Generator, is being retired by AWS and is reaching end of life in AI Agent Foundry no later than the end of September 2026 — possibly sooner, since AWS automatically disables a Bedrock model after 30 days without use and Nova Canvas has already stopped responding in the Tokyo region. AI Agent Foundry will not add a replacement image generation model, so existing Image Generators will stop working and you will no longer be able to create new ones once Nova Canvas reaches end of life. For image generation going forward, use the GPT Image model available in Treasure AI Studio. See Supported LLM Models for details.
