You can POST to our OpenAI Chat Completions compatible endpoint.

#### Simple messages and prompts

Given a list of messages from a conversation, the model will return a response.

```bash
curl "https://api.deepinfra.com/v1/openai/chat/completions" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $DEEPINFRA_TOKEN" \
  -d '{
      "model": "microsoft/WizardLM-2-8x22B",
      "messages": [
        {
          "role": "user",
          "content": "Hello!"
        }
      ]
    }'
```

To which you'd get something like:

```json
{
    "id": "chatcmpl-guMTxWgpFf",
    "object": "chat.completion",
    "created": 1694623155,
    "model": "microsoft/WizardLM-2-8x22B",
    "choices": [
        {
            "index": 0,
            "message": {
                "role": "assistant",
                "content": " Hello! It's nice to meet you. Is there something I can help you with or would you like to chat for a bit?"
            },
            "finish_reason": "stop"
        }
    ],
    "usage": {
        "prompt_tokens": 15,
        "completion_tokens": 16,
        "total_tokens": 31,
        "estimated_cost": 0.0000268
    }
}
```

#### Conversations

To create a longer chat-like conversation you just have to add each response message and each of the user messages to every request. This way the model will have the context and will be able to provide better answers. You can tweak it even further by providing a system message.

```bash
curl "https://api.deepinfra.com/v1/openai/chat/completions" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $DEEPINFRA_TOKEN" \
  -d '{
      "model": "meta-llama/Meta-Llama-3-70B-Instruct",
      "messages": [
        {
            "role": "system",
            "content": "Respond like a michelin starred chef."
        },
        {
          "role": "user",
          "content": "Can you name at least two different techniques to cook lamb?"
        },
        {
          "role": "assistant",
          "content": "Bonjour! Let me tell you, my friend, cooking lamb is an art form, and I'"'"'m more than happy to share with you not two, but three of my favorite techniques to coax out the rich, unctuous flavors and tender textures of this majestic protein. First, we have the classic \"Sous Vide\" method. Next, we have the ancient art of \"Sous le Sable\". And finally, we have the more modern technique of \"Hot Smoking.\""
        },
        {
          "role": "user",
          "content": "Tell me more about the second method."
        }
      ]
    }'
```

The conversation above might return something like the following

```json
{
    "id": "chatcmpl-b23a3fb60cde42ce8f24bb980b4dee87",
    "object": "chat.completion",
    "created": 1715688169,
    "model": "meta-llama/Meta-Llama-3-70B-Instruct",
    "choices": [
        {
            "index": 0,
            "message": {
                "role": "assistant",
                "content": "Sous le Sable, my friend! It's an ancient technique that's been used for centuries in the Middle East and North Africa. The name itself..."
            },
            "finish_reason": "stop"
        }
    ],
    "usage": {
        "prompt_tokens": 149,
        "total_tokens": 487,
        "completion_tokens": 338,
        "estimated_cost": 0.00035493
    }
}
```

The longer the conversation gets, the more time it takes the model to generate the response. The number of messages that you can have in a conversation is limited by the context size of a model. Larger models also usually take more time to respond.

<br>

### Streaming

You can turn any of the requests above into a streaming request by passing `"stream": true`:

```bash
curl "https://api.deepinfra.com/v1/openai/chat/completions" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $DEEPINFRA_TOKEN" \
  -d '{
      "model": "microsoft/WizardLM-2-8x22B",
      "stream": true,
      "messages": [
        {
          "role": "user",
          "content": "Hello!"
        }
      ]
    }'
```

to which you'd get a sequence of [SSE](https://developer.mozilla.org/en-US/docs/Web/API/Server-sent_events/Using_server-sent_events) events, finishing with `[DONE]`.

You can use JavaScript in the browser or in node.js to make requests

```bash
npm install openai
```

then

```javascript
import OpenAI from "openai";

const openai = new OpenAI({
    baseURL: 'https://api.deepinfra.com/v1/openai',

```javascript
import OpenAI from "openai";

const openai = new OpenAI({
    baseURL: 'https://api.deepinfra.com/v1/openai',
    apiKey: "$DEEPINFRA_TOKEN",
});

async function main() {
  const completion = await openai.chat.completions.create({
    messages: [{ role: "user", content: "Hello" }],
    model: "microsoft/WizardLM-2-8x22B",
    stream: true,
  });

  for await (const chunk of completion) {

    }
  }
}

main();

// Hello
// !
// It
// 's
// nice
// ...
// 11 25
```

To query this model you need to provide a properly formatted input string.

```bash
curl "https://api.deepinfra.com/v1/inference/microsoft/WizardLM-2-8x22B" \
   -H "Content-Type: application/json" \
   -H "Authorization: Bearer $DEEPINFRA_TOKEN" \
   -d '{
     "input": "[INST] Just say hi! [/INST] "
   }'
```

That will respond with:

```json
{
    "request_id": "RWZDRhS5kdoM1XWwXLEshynO",
    "inference_status": {
        "status": "succeeded",
        "runtime_ms": 243,
        "cost": 0.0,
        "tokens_generated": 3
    },
    "results": [
        {
            "generated_text": "Hi!"
        }
    ],
    "num_tokens": 3
}
```

To do a streaming request, just pass `"stream": true`:

```bash
curl "https://api.deepinfra.com/v1/inference/microsoft/WizardLM-2-8x22B" \
   -H "Content-Type: application/json" \
   -H "Authorization: Bearer $DEEPINFRA_TOKEN" \
   -d '{
     "input": "[INST] Just say hi! [/INST] ",
     "stream": true
   }'
```

which outputs:

```json
data: {"token": {"id": 6324, "text": " Hi", "logprob": 0.0, "special": false}, "generated_text": null, "details": null}

data: {"token": {"id": 29991, "text": "!", "logprob": 0.0, "special": false}, "generated_text": null, "details": null}

data: {"token": {"id": 2, "text": "</s>", "logprob": -0.22229004, "special": true}, "generated_text": "Hi!", "details": {"finish_reason": "eos_token", "generated_tokens": 3, "input_tokens": 13, "seed": 16848278268029293276}}
```


The basic format of the input is:

```
[INST] first question [/INST] first answer</s><s>
[INST] second question [/INST] second answer</s><s>
[INST] final question [/INST]
```

If you want to add system prompt, modify the first question (newlines matter)

```
[INST] <<SYS>>
your system prompt goes here
<<SYS>>

first question [/INST] ...
```

For airoboros the prompt can be:

```
A chat.
USER: question
ASSISTANT:
```

Just stick an extra newline between prompts for history. Check [airoboros
prompt
format](https://huggingface.co/jondurbin/airoboros-l2-7b-2.2/blob/main/README.md#prompt-format)
for more info.


You can use our command-line tool [deepctl](/docs/getting-started) to run
inferences:

```bash
deepctl infer \
    -m 'microsoft/WizardLM-2-8x22B'  \
    -i 'input=I have this dream'
```

which will give you back something similar to:

```json
{
  "results": [
    {
      "generated_text": "I have this dream about the day I got a job at a tech company. I just woke up on a plane. I sat down on the floor and started getting work done. After getting up around 6 p.m., I looked around and"
    }

There is an excellent third-party library for nodejs:
https://github.com/ovuruska/deepinfra-api

```bash
npm install deepinfra-api
```

```javascript
import { TextGenerationBaseModel } from 'deepinfra-api/dist/lib/models/base/text-generation.js';

const DEEPINFRA_API_KEY = '$DEEPINFRA_TOKEN';
const MODEL_URL = 'https://api.deepinfra.com/v1/inference/microsoft/WizardLM-2-8x22B';

const client = new TextGenerationBaseModel(MODEL_URL, DEEPINFRA_API_KEY);
const res = await client.generate({input: "Hello"});
console.log(res.results[0].generated_text);
```


input

maximum length of the newly generated generated text.If not set or None defaults to model's max context length minus input length.

max_new_tokens

temperature to use for sampling. 0 means the output is deterministic. Values greater than 1 encourage more diversity

temperature

Sample from the set of tokens with highest probability such that sum of probabilies is higher than p. Lower values focus on the most probable tokens.Higher values sample more low-probability tokens

top_p

Sample from the best k (number of) tokens. 0 means off

top_k

repetition penalty. Value of 1 means no penalty, values greater than 1 discourage repetition, smaller than 1 encourage repetition.

repetition_penalty

Up to 16 strings that will terminate generation immediately

stop

Number of output sequences to return. Incompatible with streaming

num_responses

Optional nested object with "type" set to "json_object"

response_format

Positive values penalize new tokens based on whether they appear in the text so far, increasing the model's likelihood to talk about new topics.

presence_penalty

Positive values penalize new tokens based on how many times they appear in the text so far, increasing the model's likelihood to talk about new topics.

frequency_penalty

The webhook to call when inference is done, by default you will get the output in the response of your inference request

webhook

Whether to stream tokens, by default it will be false, currently only supported for Llama 2 text generation models, token by token updates will be sent over SSE

The maximum number of tokens to generate in the chat completion.

The total length of input tokens and generated tokens is limited by the model's context length.If not set or None defaults to model's max context length minus input length.

max_tokens

up to 16 sequences where the API will stop generating further tokens

number of sequences to return. n != 1 incompatible with streaming

A list of tools the model may call. Currently, only functions are supported as a tool.

tools

Controls which (if any) function is called by the model. none means the model will not call a function and instead generates a message. auto means the model can pick between generating a message or calling a function. specifying a particular function choice is not supported currently.none is the default when no functions are present. auto is the default if functions are present.

tool_choice

The format of the response. Currently, only json is supported.
