assistant
When you ask for help, Four improves your prompt, checks the model and settings you selected, and helps you choose the most sensible path before you generate.
- Improves rough prompts and can suggest useful negative prompts
- Checks model capability, settings, likely quality, risk, and cost
- Finds a lower-cost capable model when one can realistically do the job
- Flags when a more capable model is the smarter choice and explains why
Premium video model
- Excellent visual quality
- Strong for complex scenes
Capable lower-cost model
- Good fit for this prompt
- Lower expected cost
Recommendations depend on the prompt. Four may recommend a more capable model when a cheaper option is unlikely to produce the result you want.
