Here's an example of the Kotlin API definition for the chat completion endpoint: | ||
|
||
```kotlin | ||
package com.tddworks.ollama.api.internal | ||
|
||
import com.tddworks.ollama.api.internal.model.ChatRequest | ||
import com.tddworks.ollama.api.internal.model.ChatResponse | ||
import retrofit2.http.Body | ||
import retrofit2.http.POST | ||
|
||
interface ChatApi { | ||
@POST("/api/chat") | ||
suspend fun generateChat( | ||
@Body request: ChatRequest | ||
): ChatResponse | ||
} | ||
``` | ||
|
||
The `ChatApi` interface defines a single method, `generateChat`, which takes a `ChatRequest` object as an input parameter and returns a `ChatResponse` object. | ||
|
||
The `ChatRequest` class would look like this: | ||
|
||
```kotlin | ||
data class ChatRequest( | ||
@field:JsonProperty("model") val model: String, | ||
@field:JsonProperty("messages") val messages: List<Message>, | ||
@field:JsonProperty("format") val format: String? = null, | ||
@field:JsonProperty("options") val options: Map<String, Any>? = null, | ||
@field:JsonProperty("stream") val stream: Boolean? = null, | ||
@field:JsonProperty("keep_alive") val keepAlive: String? = null | ||
) | ||
|
||
data class Message( | ||
@field:JsonProperty("role") val role: String, | ||
@field:JsonProperty("content") val content: String, | ||
@field:JsonProperty("images") val images: List<String>? = null | ||
) | ||
``` | ||
|
||
The `ChatResponse` class would look like this: | ||
|
||
```kotlin | ||
data class ChatResponse( | ||
@field:JsonProperty("model") val model: String, | ||
@field:JsonProperty("created_at") val createdAt: String, | ||
@field:JsonProperty("message") val message: Message?, | ||
@field:JsonProperty("done") val done: Boolean?, | ||
@field:JsonProperty("total_duration") val totalDuration: Long?, | ||
@field:JsonProperty("load_duration") val loadDuration: Long?, | ||
@field:JsonProperty("prompt_eval_count") val promptEvalCount: Int?, | ||
@field:JsonProperty("prompt_eval_duration") val promptEvalDuration: Long?, | ||
@field:JsonProperty("eval_count") val evalCount: Int?, | ||
@field:JsonProperty("eval_duration") val evalDuration: Long? | ||
) | ||
``` | ||
|
||
This API definition assumes that you are using Retrofit for making the HTTP requests. You can then use the `ChatApi` interface in your Kotlin code to generate chat completions: | ||
|
||
```kotlin | ||
val chatApi = retrofit.create(ChatApi::class.java) | ||
|
||
val request = ChatRequest( | ||
model = "llama2", | ||
messages = listOf( | ||
Message( | ||
role = "user", | ||
content = "why is the sky blue?" | ||
) | ||
) | ||
) | ||
|
||
val response = chatApi.generateChat(request) | ||
``` | ||
|
||
The `generateChat` function will return a `ChatResponse` object, which you can then process and handle as needed in your application. |
