### Model name format ## Conventions
The model name format today is `model:tag`. Some examples are `orca:3b-q4_1` and `llama2:70b`. The tag is optional and if not provided will default to `latest`. The tag is used to identify a specific version. ### Model names
Model names follow a `model:tag` format. Some examples are `orca:3b-q4_1` and `llama2:70b`. The tag is optional and if not provided will default to `latest`. The tag is used to identify a specific version.
### Durations ### Durations
All durations are in nanoseconds. All durations are returned in nanoseconds.
## Generate a Prompt ## Generate a completion
**POST /api/generate** ```
POST /api/generate
```
### Description Generate a response for a given prompt with a provided model. This is a streaming endpoint, so will be a series of responses. The final response object will include statistics and additional data from the request.
**Generate** is the main endpoint that you will use when working with Ollama. This is used to generate a response to a prompt sent to a model. This is a streaming endpoint, so will be a series of responses. The final response will include the context and what is usually seen in the output from verbose mode. ### Parameters
- `model`: (required) the [model name](#model-names)
- `prompt`: the prompt to generate a response for
Advanced parameters:
- `options`: additional model parameters listed in the documentation for the [Modelfile](./modelfile.md#valid-parameters-and-values) such as `temperature`
- `system`: system prompt to (overrides what is defined in the `Modelfile`)
- `template`: the full prompt or prompt template (overrides what is defined in the `Modelfile`)
### Request ### Request
The **Generate** endpoint takes a JSON object with the following fields:
```JSON
{
"model": "site/namespace/model:tag",
"prompt": "You are a software engineer working on building docs for Ollama.",
"options": {
"temperature": 0.7,
}
}
``` ```
curl -X POST http://localhost:11434/api/generate -d '{
**Options** can include any of the parameters listed in the [Modelfile](./modelfile.mdvalid-parameters-and-values) documentation. The only required parameter is **model**. If no **prompt** is provided, the model will generate a response to an empty prompt. If no **options** are provided, the model will use the default options from the Modelfile of the parent model. "model": "llama2:7b",
"prompt": "Why is the sky blue?"
}'
```
### Response ### Response
The response is a stream of JSON objects with the following fields: A stream of JSON objects:
```JSON ```json
{ {
"model": "modelname", "model": "llama2:7b",
"created_at": "2023-08-04T08:52:19.385406455-07:00" "created_at": "2023-08-04T08:52:19.385406455-07:00",
"response": "the current token", "response": "The",
"done": false "done": false
} }
``` ```
The final response in the stream also includes the context and what is usually seen in the output from verbose mode. For example: The final response in the stream also includes additional data about the generation:
```JSON ```json
