## Conventions

### Model names

Model names follow a `model:tag` format, where `model` can have an optional namespace such as `example/model`. Some examples are `orca-mini:3b-q8_0` and `llama3:70b`. The tag is optional and, if not provided, will default to `latest`. The tag is used to identify a specific version.

### Durations

All durations are returned in nanoseconds.

### Streaming responses

Certain endpoints stream responses as JSON objects. Streaming can be disabled by providing `{"stream": false}` for these endpoints.

## Generate a completion

```
POST /api/generate
```

Generate a response for a given prompt with a provided model. This is a streaming endpoint, so there will be a series of responses. The final response object will include statistics and additional data from the request.

### Parameters

- `model`: (required) the [model name](#model-names)
- `prompt`: the prompt to generate a response for
- `suffix`: the text after the model response
- `images`: (optional) a list of base64-encoded images (for multimodal models such as `llava`)
- `think`: (for thinking models) should the model think before responding?

Advanced parameters (optional):

- `format`: the format to return a response in. Format can be `json` or a JSON schema
- `options`: additional model parameters listed in the documentation for the [Modelfile](./modelfile.md#valid-parameters-and-values) such as `temperature`
- `system`: system message to (overrides what is defined in the `Modelfile`)
- `template`: the prompt template to use (overrides what is defined in the `Modelfile`)
- `stream`: if `false` the response will be returned as a single response object, rather than a stream of objects
- `raw`: if `true` no formatting will be applied to the prompt. You may choose to use the `raw` parameter if you are specifying a full templated prompt in your request to the API
- `keep_alive`: controls how long the model will stay loaded into memory following the request (default: `5m`)
- `context` (deprecated): the context parameter returned from a previous request to `/generate`, this can be used to keep a short conversational memory

#### Structured outputs

Structured outputs are supported by providing a JSON schema in the `format` parameter. The model will generate a response that matches the schema. See the [structured outputs](#request-structured-outputs) example below.

#### JSON mode

Enable JSON mode by setting the `format` parameter to `json`. This will structure the response as a valid JSON object. See the JSON mode [example](#request-json-mode) below.

> [!IMPORTANT]
> It's important to instruct the model to use JSON in the `prompt`. Otherwise, the model may generate large amounts whitespace.

### Examples

#### Generate request (Streaming)

##### Request

```shell
curl http://localhost:11434/api/generate -d '{
  "model": "llama3.2",
  "prompt": "Why is the sky blue?"
}'
```

##### Response

A stream of JSON objects is returned:

```json
{
  "model": "llama3.2",
  "created_at": "2023-08-04T08:52:19.385406455-07:00",
  "response": "The",
  "done": false
}
```

The final response in the stream also includes additional data about the generation:

- `total_duration`: time spent generating the response
- `load_duration`: time spent in nanoseconds loading the model
- `prompt_eval_count`: number of tokens in the prompt
- `prompt_eval_duration`: time spent in nanoseconds evaluating the prompt
- `eval_count`: number of tokens in the response
- `eval_duration`: time in nanoseconds spent generating the response
- `context`: an encoding of the conversation used in this response, this can be sent in the next request to keep a conversational memory
- `response`: empty if the response was streamed, if not streamed, this will contain the full response

To calculate how fast the response is generated in tokens per second (token/s), divide `eval_count` / `eval_duration` * `10^9`.

```json
{
  "model": "llama3.2",
  "created_at": "2023-08-04T19:22:45.499127Z",
  "response": "",
  "done": true,

  "morning": {
    "color": "blue"
  },
  "noon": {
    "color": "blue-gray"
  },
  "afternoon": {
    "color": "warm gray"
  },
  "evening": {
    "color": "orange"
  }
}
```

#### Request (with images)

To submit images to multimodal models such as `llava` or `bakllava`, provide a list of base64-encoded `images`:

#### Request

```shell
curl http://localhost:11434/api/generate -d '{
  "model": "llava",
  "prompt":"What is in this picture?",
  "stream": false,
  "images": ["[encoded data, 4864 characters]"]
}'
```

#### Response

```json
{

  "eval_count": 44,
  "eval_duration": 736432000
}
```

#### Request (Raw Mode)

In some cases, you may wish to bypass the templating system and provide a full prompt. In this case, you can use the `raw` parameter to disable templating. Also note that raw mode will not return a context.

##### Request

```shell
curl http://localhost:11434/api/generate -d '{
  "model": "mistral",
  "prompt": "[INST] why is the sky blue? [/INST]",
  "raw": true,
  "stream": false
}'
```

#### Request (Reproducible outputs)

For reproducible outputs, set `seed` to a number:

##### Request

```shell
curl http://localhost:11434/api/generate -d '{
  "model": "mistral",
  "prompt": "Why is the sky blue?",
  "options": {
    "seed": 123
  }
}'
```

##### Response

```json
{
  "model": "mistral",
  "created_at": "2023-11-03T15:36:02.583064Z",

  "eval_count": 110,
  "eval_duration": 1779061000
}
```

#### Generate request (With options)

If you want to set custom options for the model at runtime rather than in the Modelfile, you can do so with the `options` parameter. This example sets every available option, but you can set any of them individually and omit the ones you do not want to override.

##### Request

```shell
curl http://localhost:11434/api/generate -d '{
  "model": "llama3.2",
  "prompt": "Why is the sky blue?",

#### Load a model

If an empty prompt is provided, the model will be loaded into memory.

##### Request

```shell
curl http://localhost:11434/api/generate -d '{
  "model": "llama3.2"
}'
```

##### Response

A single JSON object is returned:

  "response": "",
  "done": true
}
```

#### Unload a model

If an empty prompt is provided and the `keep_alive` parameter is set to `0`, a model will be unloaded from memory.

##### Request

```shell
curl http://localhost:11434/api/generate -d '{
  "model": "llama3.2",
  "keep_alive": 0
}'
```

##### Response

A single JSON object is returned:

```json
{
  "model": "llama3.2",
  "created_at": "2024-09-12T03:54:03.516566Z",
  "response": "",
  "done": true,
  "done_reason": "unload"
}
```

## Generate a chat completion

```
POST /api/chat
```

Generate the next message in a chat with a provided model. This is a streaming endpoint, so there will be a series of responses. Streaming can be disabled using `"stream": false`. The final response object will include statistics and additional data from the request.

### Parameters

- `model`: (required) the [model name](#model-names)
- `messages`: the messages of the chat, this can be used to keep a chat memory
- `tools`: list of tools in JSON for the model to use if supported
- `think`: (for thinking models) should the model think before responding?

The `message` object has the following fields:

- `role`: the role of the message, either `system`, `user`, `assistant`, or `tool`
- `content`: the content of the message
- `thinking`: (for thinking models) the model's thinking process
- `images` (optional): a list of images to include in the message (for multimodal models such as `llava`)
- `tool_calls` (optional): a list of tools in JSON that the model wants to use
- `tool_name` (optional): add the name of the tool that was executed to inform the model of the result 

Advanced parameters (optional):

- `format`: the format to return a response in. Format can be `json` or a JSON schema. 
- `options`: additional model parameters listed in the documentation for the [Modelfile](./modelfile.md#valid-parameters-and-values) such as `temperature`
- `stream`: if `false` the response will be returned as a single response object, rather than a stream of objects
- `keep_alive`: controls how long the model will stay loaded into memory following the request (default: `5m`)

### Tool calling

Tool calling is supported by providing a list of tools in the `tools` parameter. The model will generate a response that includes a list of tool calls. See the [Chat request (Streaming with tools)](#chat-request-streaming-with-tools) example below.

Models can also explain the result of the tool call in the response. See the [Chat request (With history, with tools)](#chat-request-with-history-with-tools) example below.

[See models with tool calling capabilities](https://ollama.com/search?c=tool).

### Structured outputs

Structured outputs are supported by providing a JSON schema in the `format` parameter. The model will generate a response that matches the schema. See the [Chat request (Structured outputs)](#chat-request-structured-outputs) example below.

## Create a Model

```
POST /api/create
```

Create a model from:
 * another model;
 * a safetensors directory; or
 * a GGUF file.

If you are creating a model from a safetensors directory or from a GGUF file, you must [create a blob](#create-a-blob) for each of the files and then use the file name and SHA256 digest associated with each blob in the `files` field.

### Parameters

- `model`: name of the model to create
- `from`: (optional) name of an existing model to create the new model from
- `files`: (optional) a dictionary of file names to SHA256 digests of blobs to create the model from
- `adapters`: (optional) a dictionary of file names to SHA256 digests of blobs for LORA adapters
- `template`: (optional) the prompt template for the model
- `license`: (optional) a string or list of strings containing the license or licenses for the model
- `system`: (optional) a string containing the system prompt for the model
- `parameters`: (optional) a dictionary of parameters for the model (see [Modelfile](./modelfile.md#valid-parameters-and-values) for a list of parameters)
- `messages`: (optional) a list of message objects used to create a conversation
- `stream`: (optional) if `false` the response will be returned as a single response object, rather than a stream of objects
- `quantize` (optional): quantize a non-quantized (e.g. float16) model

#### Quantization types

| Type | Recommended |
| --- | :-: |
| q4_K_M | * |
| q4_K_S | |
| q8_0 | * |

## Copy a Model

```
POST /api/copy
```

Copy a model. Creates a model with another name from an existing model.

### Examples

#### Request

```shell
curl http://localhost:11434/api/copy -d '{
  "source": "llama3.2",
  "destination": "llama3-backup"
}'
```

#### Response

Returns a 200 OK if successful, or a 404 Not Found if the source model doesn't exist.

## Delete a Model

```
DELETE /api/delete
```

Delete a model and its data.

### Parameters

- `model`: model name to delete

### Examples

#### Request

```shell
curl -X DELETE http://localhost:11434/api/delete -d '{
  "model": "llama3:13b"
}'
```

#### Response

Returns a 200 OK if successful, 404 Not Found if the model to be deleted doesn't exist.

## Pull a Model

```
POST /api/pull
```

Download a model from the ollama library. Cancelled pulls are resumed from where they left off, and multiple calls will share the same download progress.

### Parameters

- `model`: name of the model to pull
- `insecure`: (optional) allow insecure connections to the library. Only use this if you are pulling from your own library during development.
- `stream`: (optional) if `false` the response will be returned as a single response object, rather than a stream of objects

### Examples

#### Request

```shell
curl http://localhost:11434/api/pull -d '{
  "model": "llama3.2"
}'
```

#### Response

If `stream` is not specified, or set to `true`, a stream of JSON objects is returned:

The first object is the manifest:

```json
{
  "status": "pulling manifest"
}
```

Then there is a series of downloading responses. Until any of the download is completed, the `completed` key may not be included. The number of files to be downloaded depends on the number of layers specified in the manifest.

```json
{
  "status": "downloading digestname",
  "digest": "digestname",
  "total": 2142590208,
  "completed": 241970
}
```

After all the files are downloaded, the final responses are:

```json
{
    "status": "verifying sha256 digest"
}
{
    "status": "writing manifest"
}
{
    "status": "removing any unused layers"
}
{
    "status": "success"
}
```

if `stream` is set to false, then the response is a single JSON object:

```json
{
  "status": "success"
}
```

## Push a Model

```
POST /api/push
```

Upload a model to a model library. Requires registering for ollama.ai and adding a public key first.

### Parameters

- `model`: name of the model to push in the form of `<namespace>/<model>:<tag>`
- `insecure`: (optional) allow insecure connections to the library. Only use this if you are pushing to your library during development.
- `stream`: (optional) if `false` the response will be returned as a single response object, rather than a stream of objects

### Examples

#### Request

```shell
curl http://localhost:11434/api/push -d '{
  "model": "mattw/pygmalion:latest"
}'
```

#### Response

If `stream` is not specified, or set to `true`, a stream of JSON objects is returned:

```json
{ "status": "retrieving manifest" }
```

and then:

```json
{
  "status": "starting upload",
  "digest": "sha256:bc07c81de745696fdf5afca05e065818a8149fb0c77266fb584d9b2cba3711ab",
  "total": 1928429856
}
```

Then there is a series of uploading responses:

```json
{
  "status": "starting upload",
  "digest": "sha256:bc07c81de745696fdf5afca05e065818a8149fb0c77266fb584d9b2cba3711ab",
  "total": 1928429856
}
```

Finally, when the upload is complete:

```json
{"status":"pushing manifest"}
{"status":"success"}
```

If `stream` is set to `false`, then the response is a single JSON object:

```json
{ "status": "success" }
```

## Generate Embeddings

```
POST /api/embed
```

Generate embeddings from a model

### Parameters

- `model`: name of model to generate embeddings from
- `input`: text or list of text to generate embeddings for

Advanced parameters:
