AI Model Settings
AI Model Settings tells PromptHub which model service to use, where its endpoint is, and which model should handle each supported feature.
You do not need to configure every provider. Start with one reliable text model, test the connection, then add vision or image capabilities only when a workflow needs them.

When to Open This Page
Section titled “When to Open This Page”- Before using prompt testing, AI editing, translation, or image-related features.
- After a credential expires or a provider changes its endpoint.
- When you want one feature to use a different model.
- When a team gives you a private model endpoint.
Configuration Flow
Section titled “Configuration Flow”- Open AI Model Settings.
- Choose a provider or a compatible custom service.
- Enter the credential and optional base URL supplied by that service.
- Test the connection before relying on it.
- Add or fetch models supported by the endpoint.
- Select a default model for each feature you intend to use.
Choosing a Default
Section titled “Choosing a Default”| Workflow | Practical Starting Point |
|---|---|
| Writing, summarizing, translation | A stable text model |
| Code review and long documents | A model with enough context for the input |
| Image prompt analysis | A model that accepts visual input |
| Repeated prompt comparison | A predictable model with acceptable cost and latency |
Model names and availability come from the provider or custom endpoint, so they can change independently of PromptHub.
Troubleshooting
Section titled “Troubleshooting”| Message | Likely Cause | What to Check |
|---|---|---|
| No model configured | The feature has no default route | Select a default model for that feature |
| Authentication failed | Invalid credential or missing provider permission | Re-enter the credential and check account access |
| Connection timed out | Network, proxy, or endpoint issue | Check the network and base URL, then retry |
| 504 | The model or gateway did not answer in time | Retry later or choose a more reliable endpoint |
Security
Section titled “Security”Store model credentials only in the product’s local configuration or a trusted environment-variable boundary. Never place them in prompts, skills, rules, screenshots, or public documentation.
