Glossary
Model Types and Modalities
On BizyAir, models are classified by modality: text (LLM), vision (VLM), image, video, and audio.
By invocation method, they are divided into four types: “Online Playground”, “API Integration”, “ComfyUI Node”, and “AI App”.
Each model’s support modality, input/output format, and billing method are noted on its Node Pricing detail page.
Prompt Engineering and Output Control
- Prompt: The positive prompt describes the target content; the negative prompt describes elements to avoid.
- Aspect control: Control output dimensions via
width / height / aspect.
- Sampling quality: Control sampling steps and guidance strength via
steps / guidance.
- Reproducibility: Fix
seed to lock the result; set to -1 for random.
- Safety limits: Overly long text triggers a
Prompt Validation Error; sensitive descriptions trigger a safety intercept.
Video generation time scales with duration — validate the effect with a short clip first before scaling up.
Account System and Content Lifecycle
- Single identity system: The web and API sides share the same account and balance.
- API Key: An API Key is an account-level credential. Keep it safe; if leaked, reset it under “User Center → API Keys”.
- Content retention: Content is retained for 15 days by default — please download it in time.
