Dify version

0.6.15

Cloud or Self Hosted

Self Hosted (Docker)

Steps to reproduce

It's an regresion of #4460 or a variant with custom model.

Just add a OpenAI configuration or model.

Model Name: custom-model-name

API Key: sk-custom-one

Org: Ecma Org

API Base: http://your.litellm.hostname:4000

Hostname is accesible from the container. Other services are using the same LiteLLM Proxy without issue

✔️ Expected Behavior

While LiteLLM is proivding compatible Proxy with custom model list it should be able to add a custom model.

❌ Actual Behavior

Base model custom-model-name not found.

@imkebe Hello there! I'm here to assist you with any bugs, questions, or even becoming a contributor. Let's work together to solve the issue you're facing.

To resolve the issue where the custom model "gpt-3.5" is not found when connecting to an OpenAI-compatible API using a LiteLLM Proxy in a self-hosted Dify deployment, ensure that the model is correctly defined and registered in your configuration. The model should be referred to as "gpt-3.5-turbo-0125" rather than "gpt-3.5".

Here is the relevant configuration snippet:

model: gpt-3.5-turbo-0125
label:
  zh_Hans: gpt-3.5-turbo-0125
  en_US: gpt-3.5-turbo-0125
model_type: llm
features:
  - multi-tool-call
  - agent-thought
  - stream-tool-call
model_properties:
  mode: chat
  context_size: 16385
parameter_rules:
  - name: temperature
    use_template: temperature
  - name: top_p
    use_template: top_p
  - name: presence_penalty
    use_template: presence_penalty
  - name: frequency_penalty
    use_template: frequency_penalty

    type: string
    help:
      zh_Hans: 指定模型必须输出的格式
      en_US: specifying the format that the model must output
    required: false

      - json_object
pricing:
  input: '0.0005'
  output: '0.0015'
  unit: '0.001'
  currency: USD

Ensure that your API requests and configurations are using "gpt-3.5-turbo-0125" as the model identifier. If you encounter any issues with API keys or model quotas, refer to the Dify platform's settings and ensure that your model provider configurations are correctly set up ^[1][2][3][4].

I know i'm replaying to bot, however the model name in liteLLM can be custom and without of any version of gpt-3.5 exposed. I've tried with multiple model names the LiteLLM is exposing and other services are using but only Dify is in responce showing an error that the gpt-3.5 not found.

To resolve the issue where Dify returns an error stating that the base model "gpt-3.5" is not found when trying to add a custom model via a LiteLLM Proxy, ensure that the model name in Dify matches the external access name configured in LiteLLM.

Here are the steps to follow:

1. Ensure LiteLLM is properly configured and running:

   • Make sure LiteLLM is accessible. The LiteLLM request API endpoint should be available at http://127.0.0.1:8080 or the appropriate host IP if using Docker.

2. Verify Model Configuration in LiteLLM:

   • Ensure that the model is configured with the correct external access name. For example, if you have a model named custom-model-name, ensure it is correctly set up in LiteLLM.

3. Configure Dify to use the correct model name and server URL:

   • Go to Settings > Model Providers > LocalAI in Dify.
   • Add the model with the following details:
     • Model Type: Text Generation
     • Model Name: custom-model-name (this should match the external access name configured in LiteLLM)
     • Server URL: Use the appropriate URL. If Dify is deployed via Docker, use the host IP address instead of localhost. For example, http://192.168.1.100:8080.

Here is a summary of the configuration:

Model 1: `custom-model-name`

- Model Type: Text Generation
- Model Name: `custom-model-name`
- Server URL: http://<your-LiteLLM-endpoint-domain>:8080 (e.g., http://192.168.1.100:8080)

Make sure to click "Save" to apply the configuration.

By ensuring that the model name in Dify matches the external access name configured in LiteLLM and using the correct server URL, you should be able to resolve the error ^[1][2][3].

LocalAI cannot be used as a Dify backend because there is no field to put the access key. However all mentioned points are correct. The issue seems to be a default unnecessary dependency of gpt-3.5 model in response of OpenAI endpoint.

Hello we do not have 2.19.4 this version. Can you edit that again?

It's 0.6.15

The newly launched GitHub Models also encountered the same situation, as GitHub Models do not provide the GPT-3.5 model, making it unusable. Since OpenAI announced that 3.5 will be phased out, it is recommended to change the default verification model to GPT-4o-mini.
