📤 Chat Completion
With the chatCompletion
function, you can obtain a textual response to a conversation with some context, using providers and models designed for this task. Additionally, you can manipulate the answer before converting it to a stream or force the AI to give you a certain answer by generating several retries.
⚙️ Basic Usage
Simple Fetch
It will capture the messages and the context, and any provider will respond with a string.
// CommonJS
const getGPT4js = require("gpt4js");
const GPT4js = await getGPT4js();
// ESM
import GPT4js from "gpt4js";
const messages = [{ role: "user", content: "hi!" }];
const options = {
provider: "Nextway",
model: "gpt-4o-free",
};
(async () => {
const provider = GPT4js.createProvider(options.provider);
try {
const text = await provider.chatCompletion(messages, options, (data) => {
console.log(data);
});
console.log(text);
} catch (error) {
console.error("Error:", error);
}
})();
Note: The conversation needs to include at least one message with the role user to provide a proper answer.
Give Your Instructions
You can provide your own instructions for the conversation before it starts using the system role.
const messages = [
{ role: "system", content: "You're an expert bot in programming." },
{ role: "user", content: "Hi, write me something." },
];
const options = {
provider: "Nextway",
model: "gpt-4o-free",
};
(async () => {
const provider = GPT4js.createProvider(options.provider);
try {
const text = await provider.chatCompletion(messages, options, (data) => {
console.log(data);
});
console.log(text);
} catch (error) {
console.error("Error:", error);
}
})();
Conversation Roles
| Role | Description |
| ----------- | ---------------------------------------------------------------------- |
| system
| Used for providing instructions and context prior to the conversation. |
| user
| Used to identify user messages |
| assistant
| Used to identify AI messages |
🔩 Configurable Options
| Option | Type | Description |
| --------------- | ------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| provider
| string | Choose the provider to use for chat completions. Possible values include Nextway
, BlackBox
, etc. This determines which service will handle the request. |
| model
| string | Choose the model to use by a provider that supports it. For example, gpt-4
, gpt-3.5-turbo
, etc. This specifies the particular language model for generating completions. |
| stream
| boolean | Determine if the data should be streamed in parts or not. If true
, the response will be streamed in real-time as it's generated. If false
, the response will be sent all at once. |
| temperature
| number | Set the temperature to control the randomness of the output. A value between 0 and 1 where higher values (closer to 1) make the output more random, and lower values (closer to 0) make it more deterministic. |
| webSearch
| boolean | Enable or disable web search functionality. If true
, the system can perform web searches to gather real-time information. If false
, it relies solely on pre-existing data. |
| codeModelMode
| boolean | Enable or disable the code model mode. If true
, the system will use a model optimized for understanding and generating code. If false
, it uses the general-purpose language model. |
| isChromeExt
| boolean | Specify whether the system is being used as a Chrome extension. If true
, it indicates integration with Chrome, possibly affecting certain functionalities and permissions. |
