Examples

Using OpenAI Official Library

Python

import openai

openai.api_key = 'anything'
openai.base_url = "http://localhost:5000/v1/"

completion = openai.chat.completions.create(
    model="gpt-4o-mini",
    messages=[
        {"role": "user", "content": "Hello"},
    ],
)

print(completion.choices[0].message.content)

Node.js

import OpenAI from 'openai';

const openai = new OpenAI({
    apiKey: "anything",
    baseURL: "http://localhost:5000/v1/",
});

const chatCompletion = await openai.chat.completions.create({
  messages: [{ role: 'user', content: 'Echo Hello' }],
  model: 'gpt-4o-mini',
});

console.log(chatCompletion.choices[0].message.content);

Notes

Nginx config

If you are using Nginx as a reverse proxy for llm-web-api, add the following configuration to optimize the streaming output and improve the user experience.

# Disable proxy buffering. When set to off, Nginx sends client requests to the backend server immediately and sends responses back to the client immediately.
proxy_buffering off;

# Enable chunked transfer encoding. This allows the server to send data in chunks for dynamically generated content without knowing the size of the content in advance.
chunked_transfer_encoding on;

# Enable TCP_NOPUSH, which tells Nginx to send data as efficiently as possible before sending data packets to the client. This is often used with sendfile to improve network efficiency.
tcp_nopush on;

# Enable TCP_NODELAY, which tells Nginx not to delay sending data and to send small data packets immediately. In some cases, this can reduce network latency.
tcp_nodelay on;

# Set the keepalive timeout, here set to 120 seconds. If there is no further communication between the client and the server within this period, the connection will be closed.
keepalive_timeout 120;

Token

Since inference is not performed on the llm-web-api side, token statistics will be returned as fixed number!!!!!
