# <span style={{ 'color': 'gray' }}>module</span>  pixeltable.functions.fireworks

Pixeltable UDFs
that wrap various endpoints from the Fireworks AI API. In order to use them, you must
first `pip install fireworks-ai` and configure your Fireworks AI credentials, as described in
the [Working with Fireworks](https://docs.pixeltable.com/notebooks/integrations/working-with-fireworks) tutorial.

## <span style={{ 'color': 'gray' }}>udf</span>  chat\_completions()

```python Signature theme={null}
@pxt.udf
chat_completions(messages: pxt.Json[(Json, *, model: pxt.String, model_kwargs: pxt.Json | None = None) -> pxt.Json
```

Creates a model response for the given chat conversation.

Equivalent to the Fireworks AI `chat/completions` API endpoint.
For additional details, see: [https://docs.fireworks.ai/api-reference/post-chatcompletions](https://docs.fireworks.ai/api-reference/post-chatcompletions)

Request throttling:
Applies the rate limit set in the config (section `fireworks`, key `rate_limit`). If no rate
limit is configured, uses a default of 600 RPM.

**Requirements:**

* `pip install fireworks-ai`

**Parameters:**

* **`messages`** (`pxt.Json[(Json`): A list of messages comprising the conversation so far.
* **`model`** (`Any`): The name of the model to use.
* **`model_kwargs`** (`Any`): Additional keyword args for the Fireworks `chat_completions` API. For details on the available
  parameters, see: [https://docs.fireworks.ai/api-reference/post-chatcompletions](https://docs.fireworks.ai/api-reference/post-chatcompletions)

**Returns:**

* `pxt.Json`: A dictionary containing the response and other metadata.

**Examples:**

Add a computed column that applies the model `accounts/fireworks/models/mixtral-8x22b-instruct` to an existing Pixeltable column `tbl.prompt` of the table `tbl`:

```python  theme={null}
messages = [{'role': 'user', 'content': tbl.prompt}]
tbl.add_computed_column(
    response=chat_completions(
        messages, model='accounts/fireworks/models/mixtral-8x22b-instruct'
    )
)
```
