Dify
Dify connects any OpenAI-compatible service through the OpenAI-API-compatible model provider. Add each model on its own, and change a few defaults.
Before you start
- A workspace owner or admin account; only they can set up model providers.
- Install OpenAI-API-compatible (the official langgenius plugin) from the Marketplace.
Add a model
Open Model Provider (under Integrations in newer versions, Settings in older ones), click Add Model on the OpenAI-API-compatible card and fill in the form as below:
| Field | Value |
|---|---|
| Model Type | LLM |
| Model Name | The exact model id, such as gpt-5.5 |
| API Key | Your NezhaGate API key |
| API Base URL | https://nezhagate.com/v1 |
| Completion mode | Chat |
| Model context size | The model's real context length (see its API doc). The default is 4096; left as is, long conversations get cut. |
| Upper bound for max tokens | The model's maximum output tokens; this also defaults to 4096. |
| Function Call Type | Tool Call for models with tool calling. The default, Not Support, keeps agents from calling tools. |
| Vision Support | Support, for models that take image input. |
| API Type | Keep Chat Completions API. |
The address must include /v1: the plugin appends /chat/completions directly. Leave the other fields at their defaults.
Claude (optional)
You can also install the official Anthropic plugin, set API URL to https://nezhagate.com/anthropic, and add Claude models one by one with Add Model (such as claude-sonnet-5).
Test
Saving sends one very short request to validate (billed on its tiny usage). Then create a chatbot in Studio, pick the model and send a message in the preview.
Troubleshooting
The address is missing /v1; it should be https://nezhagate.com/v1.
401 means the key is wrong; model not found means the model id is misspelled. Use the ids in the API reference.
Function Call Type is still Not Support in the model form; change it to Tool Call.
Model context size and Upper bound for max tokens are still at 4096; raise them to the model's real values.
