[NousResearch/Hermes-2-Pro-Mistral-7B](https://huggingface.co/NousResearch/Hermes-2-Pro-Mistral-7B) is an open source LLM with great function calling capabilities.

This [PSR-18](https://www.php-fig.org/psr/psr-18/) plugin converts OpenAI API requests/responses that use [function calling](https://platform.openai.com/docs/guides/function-calling) to and from [the Hermes2Pro prompt format](https://huggingface.co/NousResearch/Hermes-2-Pro-Mistral-7B#prompt-format-for-function-calling).

It lets you use Hermes2Pro function calling with the same OpenAI api client code that you currently use.

[An http proxy docker image](#docker-proxy) is available for non PHP projects.

PHP Library
===========

[](#php-library)

Install [ollama](https://ollama.com/) ([docker](https://ollama.com/blog/ollama-is-now-available-as-an-official-docker-image)) and pull the model:

```
$ ollama pull adrienbrault/nous-hermes2pro:Q4_K_M
```

Install [this package](https://packagist.org/packages/adrienbrault/hermes2pro):

```
$ composer require adrienbrault/hermes2pro:@dev
```

Then update your code to use the plugin:

```
use AdrienBrault\Hermes2Pro\Hermes2ProPlugin;
use Http\Client\Common\PluginClient;
use Http\Discovery\Psr18ClientDiscovery;

require_once __DIR__ . '/vendor/autoload.php';

$client = OpenAI::factory()
    ->withApiKey(getenv('OPENAI_API_KEY'))
    ->withBaseUri(sprintf(
        '%s/v1',
        getenv('OLLAMA_HOST') ?: 'http://localhost:11434'
    ))
    ->withHttpClient(
        new PluginClient(
            Psr18ClientDiscovery::find(),
            [
                new Hermes2ProPlugin()
            ]
        )
    )
    ->make()
;
```

Then use `adrienbrault/nous-hermes2pro:Q4_K_M` as the `model` in your chat requests. There are [more tags/quantizations available](https://ollama.com/adrienbrault/nous-hermes2pro/tags).

The model and this plugin supports parallel function calling. Note that streaming is not currently supported.

Note that the plugin is only active if the request/response model starts with `adrienbrault/nous-hermes2pro`.

See [demo/](demo/).

Docker Proxy
============

[](#docker-proxy)

A docker http proxy is available to convert requests/responses to/from the Hermes2Pro format:

```
$ docker run -it --rm \
    -e OPENAI_BASE_URI=http://docker.for.mac.host.internal:11434 \
    -p 11440:80 \
    adrienbrault/hermes2pro-proxy

$ MODEL="adrienbrault/nous-hermes2pro:Q4_K_M" \
    OPENAI_BASE_URI="http://localhost:11440/v1" \
    php demo/openai.php
```
