## Installation

> [!NOTE]
> We are now publishing the artifacts to both Maven Central and GitHub package repositories.
>
> Track the releases [here](https://github.com/ollama4j/ollama4j/releases) and update the dependency version
> according to your requirements.

### For Maven

#### Using [Maven Central](https://central.sonatype.com/)

[![][ollama4j-mvn-releases-shield]][ollama4j-mvn-releases-link]

[ollama4j-mvn-releases-link]: https://central.sonatype.com/artifact/io.github.ollama4j/ollama4j/overview

[ollama4j-mvn-releases-shield]: https://img.shields.io/maven-central/v/io.github.ollama4j/ollama4j?display_name=release&style=for-the-badge&label=From%20Maven%20Central

In your Maven project, add this dependency:

```xml

<dependency>
    <groupId>io.github.ollama4j</groupId>
    <artifactId>ollama4j</artifactId>
    <version>1.0.78</version>
</dependency>
```

#### Using GitHub's Maven Package Repository

[![][ollama4j-releases-shield]][ollama4j-releases-link]

[ollama4j-releases-link]: https://github.com/ollama4j/ollama4j/releases

[ollama4j-releases-shield]: https://img.shields.io/github/v/release/ollama4j/ollama4j?display_name=release&style=for-the-badge&label=From%20GitHub%20Packages

1. Add `GitHub Maven Packages` repository to your project's `pom.xml` or your `settings.xml`:

```xml

<repositories>
    <repository>
        <id>github</id>
        <name>GitHub Apache Maven Packages</name>
        <url>https://maven.pkg.github.com/ollama4j/ollama4j</url>
        <releases>
            <enabled>true</enabled>
        </releases>
        <snapshots>
            <enabled>true</enabled>
        </snapshots>
    </repository>
</repositories>
```

2. Add `GitHub` server to settings.xml. (Usually available at ~/.m2/settings.xml)

```xml

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0
                      http://maven.apache.org/xsd/settings-1.0.0.xsd">
    <servers>
        <server>
            <id>github</id>
            <username>YOUR-USERNAME</username>
            <password>YOUR-TOKEN</password>
        </server>
    </servers>
</settings>
```

3. In your Maven project, add this dependency:

```xml

<dependency>
    <groupId>io.github.ollama4j</groupId>
    <artifactId>ollama4j</artifactId>
    <version>1.0.78</version>
</dependency>
```

##### For Gradle

1. Add the dependency

```groovy
dependencies {
  implementation 'com.github.ollama4j:ollama4j:1.0.78'
}
```

### Areas of improvement

- [x] Use Java-naming conventions for attributes in the request/response models instead of the
  snake-case conventions. (
  possibly with Jackson-mapper's `@JsonProperty`)
- [x] Fix deprecated HTTP client code
- [x] Setup logging
- [x] Use lombok
- [x] Update request body creation with Java objects
- [ ] Async APIs for images
- [ ] Support for function calling with models like Mistral
    - [x] generate in sync mode
    - [ ] generate in async mode
- [ ] Add custom headers to requests
- [x] Add additional params for `ask` APIs such as:
    - [x] `options`: additional model parameters for the Modelfile such as `temperature` -
      Supported [params](https://github.com/jmorganca/ollama/blob/main/docs/modelfile.md#valid-parameters-and-values).
    - [x] `system`: system prompt to (overrides what is defined in the Modelfile)
    - [x] `template`: the full prompt or prompt template (overrides what is defined in the Modelfile)
    - [x] `context`: the context parameter returned from a previous request, which can be used to keep a
      short
      conversational memory
    - [x] `stream`: Add support for streaming responses from the model
- [ ] Add test cases
- [ ] Handle exceptions better (maybe throw more appropriate exceptions)
