Aug 1, 2025August 2025: LianjiaTech/bella-openapi delivered a modernization of the image editing system and associated pricing/cost calculations, focusing on performance, reliability, and business value. Key improvements include integration of an image-to-image editing model, backward-compatible API protocol refinements, support for multiple input formats (Base64, URLs, MultipartFile), URL-based image fetch, enhanced error handling and user feedback, and data URI formatting improvements. Architectural improvements introduced an abstract image editing adapter to reduce duplication and renamed adapters for clarity. Pricing for image editing was added and integrated into the cost calculator. Additionally, error handling was strengthened for the OpenAI adaptor by replacing a generic RuntimeException with BizParamCheckException to improve validation accuracy and reliability.
