Where this model earns its cost — and where it doesn't.
This is a text-to-image generation model from bfl that accepts text prompts and returns image outputs. It operates in a balanced cost tier with medium generation speed and is classified as a frontier-quality model. The model does not support vision input, reasoning, or structured outputs.
On Kyma, requests run through an OpenAI-compatible endpoint at https://kymaapi.com/v1 using a single API key for all models. Every request gets automatic failover if a serving path degrades, and responses include exact billing details in the usage.cost field. The X-Kyma-Model header reports the exact model that ran.
The model is marked as legacy and does not support multi-reference inputs or the quality improvements found in newer versions. It bills per image rather than per token, and prompt caching bills repeated prompt prefixes at this model's cached input rate. For new integrations, the platform recommends moving to a successor model that offers lower costs and expanded reference capabilities.
