# Models and Model IDs
ApiSmart provides access to supported language, image, and video models through a unified API platform.
Before sending a request, select a model that fits your use case and copy its exact **Model ID**. The Model ID determines which model processes the request.
***
### 🤖 Browse Available Models
Open the ApiSmart [**Models**](https://www.apismart.ai/models) page and select a category:
* All
* Large Language Models (LLM)
* Image Generation
* Video Generation
You can switch between **Card View** and **List View** depending on how you prefer to browse the models.
Each model card may display:
* Model name
* Provider
* Model category
* Billing mode
* Pricing summary
* Capability tags
* **View Details**
* **Compare Models**
***
### Filter the Model List
Use the available filters to narrow your results by:
* **Billing Mode**
* **Provider**
* **Context Length**
* **Price Range**
* **Sorting Options**
For language models, Context Length indicates how much content a model can process in one request. Image and video models may display `N/A`.
> đź’ˇ A lower listed price does not always mean a lower total request cost. Actual cost depends on the selected model and request settings.
***
### Compare Models
Select **Compare Models** on the model cards to review suitable models side by side.
Compare factors such as:
* Provider
* Model category
* Capabilities
* Context length
* Billing mode
* Price Configuration
Use the comparison view as an initial reference, then select **View Details** before integrating the model.
***
### Open the Model Details
Select **View Details** to review the complete model information.
Depending on the model, the details page may include:
* Model description
* Capabilities
* Release date
* Price Configuration
* Code Example
* Quick Integration information, where available
The model name displayed at the top of the page may be different from the Model ID required by the API.
For example:
```
Display name: DeepSeek-V4-Flash.DeepSeek
Model ID: DEEPSEEK_V4_FLASH
```
***
### 🔍 Find the Model ID
The Model ID can usually be found in two places on the details page.
#### Code Example
Look for the value assigned to the `model` field:
```python
data = {
"model": "DEEPSEEK_V4_FLASH",
"messages": [
{
"role": "user",
"content": "Hello!"
}
]
}
```
In this example, the Model ID is:
```
DEEPSEEK_V4_FLASH
```
#### Quick Integration
The **Quick Integration** section may also display the Model ID.
Do not:
* Replace it with the display name
* Change uppercase or lowercase letters
* Remove underscores, hyphens, or periods
* Add extra spaces
> ⚠️ **Important:** Model IDs are case-sensitive.
***
### Use the Model ID in a Request
#### Text Model Example
```python
{
"model": "DEEPSEEK_V4_FLASH"
}
```
Replace `DEEPSEEK_V4_FLASH` with the exact Model ID shown in the selected model’s Code Example.
For complete request examples, see [**Chat Completions API**](/api-guides/chat-completions-api.md), [**Image Generation API**](/api-guides/image-generation-api.md), or [**Video Generation API**](/api-guides/video-generation-api.md).
***
### Use the Correct Endpoint and Request Format
Different model categories use different endpoints and request structures.
Always refer to the model’s **Code Example** before integration.
| Model category | Endpoint | Common request fields |
| -------------- | ------------------------ | ------------------------------------------------- |
| Language | `/v1/chat/completions` | Uses `messages` and a supported language Model ID |
| Image | `/v1/images/generations` | Uses model-specific image generation fields |
| Video | `/v1/video/tasks` | Creates an asynchronous video task |
> ⚠️ **Important:** Always use the exact endpoint, Model ID, and request format shown in the model’s **Code Example**.
***
### đź’° Review Pricing Before Selection
Before selecting a model, review its **Billing Mode** and **Price Configuration**.
Pricing may vary by model, input type, output type, resolution, duration, or other model-specific settings.
For details, see [**Understand Model Pricing and Billing**](/models-and-pricing/model-pricing-and-billing.md).
***
### 🛠️ Troubleshoot Model ID and Request Errors
If a model request fails, first check that:
* The Model ID was copied from the model’s **Code Example**
* The display name was not used as the Model ID
* Capitalization and punctuation are unchanged
* The correct endpoint is being used
* The request fields match the selected model
* The model is currently available
Example:
```
Display name: DeepSeek-V4-Flash.DeepSeek
Model ID: DEEPSEEK_V4_FLASH
```
Incorrect:
```
{ "model": "DeepSeek-V4-Flash.DeepSeek"}
```
Correct:
```
{ "model": "DEEPSEEK_V4_FLASH"}
```
If the Model ID and request format are correct but the request still fails, check your **API Token status, remaining usage allowance, Current Balance, and Usage Logs**.
