# API
## Endpoints
- [Generate a completion](#generate-a-completion)
- [Create a model](#create-a-model)
- [List local models](#list-local-models)
- [Copy a model](#copy-a-model)
- [Delete a model](#delete-a-model)
- [Pull a model](#pull-a-model)
- [Generate embeddings](#generate-embeddings)
## Conventions
### Model names
Model names follow a `model:tag` format. Some examples are `orca-mini: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
All durations are returned in nanoseconds.
## Generate a completion
```
POST /api/generate
```
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.
### 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`)
- `context`: the context parameter returned from a previous request to `/generate`, this can be used to keep a short conversational memory
### Request
```
curl -X POST http://localhost:11434/api/generate -d '{
"model": "llama2:7b",
"prompt": "Why is the sky blue?"
}'
```
### Response
A stream of JSON objects:
```json
{
"model": "llama2:7b",
"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
- `sample_count`: number of samples generated
- `sample_duration`: time spent generating samples
- `prompt_eval_count`: number of tokens in the prompt
- `prompt_eval_duration`: time spent in nanoseconds evaluating the prompt
- `eval_count`: number of tokens 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
To calculate how fast the response is generated in tokens per second (token/s), divide `eval_count` / `eval_duration`.
```json

## Copy a Model
```
POST /api/copy
