| Summary | Seedream 4.5 is ByteDance's advanced AI image generation and editing model, representing a major evolution of the Seedream family. It delivers professional-grade visual quality with rich detail, improved spatial understanding, and cinematic rendering effects. Seedream 4.5 excels at understanding nuanced natural language prompts and generating consistent, high-fidelity outputs with enhanced lighting, depth, and texture. It supports complex workflows such as multi-image composition, fine typography and text rendering, and image-to-image editing with enhanced prompt interpretation. | GLM-5.3 is Z.ai's large-scale reasoning model designed for complex software engineering and long-horizon agentic workflows. It supports text input and output with a 1M-token context window, enabling sustained reasoning across large codebases and extended multi-step tasks. Building on GLM-5.2, it delivers stronger coding performance while improving the balance between capability and token efficiency, making it well suited for autonomous coding agents, large-scale engineering workflows, and complex task execution. |
