from openai import OpenAI
from portkey_ai import PORTKEY_GATEWAY_URL

# 1. Install: pip install openai portkey-ai
# 2. Add @lemonfox-ai provider in model catalog
# 3. Use it:

client = OpenAI(
    api_key="PORTKEY_API_KEY",  # Portkey API key
    base_url=PORTKEY_GATEWAY_URL
)

response = client.chat.completions.create(
    model="@lemonfox-ai/llama-8b-chat",
    messages=[{"role": "user", "content": "Hello!"}]
)

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

import OpenAI from "openai"
import { PORTKEY_GATEWAY_URL } from "portkey-ai"

// 1. Install: npm install openai portkey-ai
// 2. Add @lemonfox-ai provider in model catalog
// 3. Use it:

const client = new OpenAI({

LemonFox Capabilities

Streaming

Stream responses for real-time output:

Python

from portkey_ai import Portkey

portkey = Portkey(api_key="PORTKEY_API_KEY", provider="@lemonfox-ai")

stream = portkey.chat.completions.create(
    model="llama-8b-chat",
    messages=[{"role": "user", "content": "Tell me a story"}],
    stream=True
)

for chunk in stream:
    print(chunk.choices[0].delta.content or "", end="", flush=True)

import Portkey from 'portkey-ai';

const portkey = new Portkey({
    apiKey: 'PORTKEY_API_KEY',
    provider: '@lemonfox-ai'
});

const stream = await portkey.chat.completions.create({
    model: 'llama-8b-chat',
    messages: [{ role: 'user', content: 'Tell me a story' }],
    stream: true
});

for await (const chunk of stream) {
    process.stdout.write(chunk.choices[0]?.delta?.content || '');
}

Image Generation

Generate images with Stable Diffusion XL:

Python

from portkey_ai import Portkey

portkey = Portkey(api_key="PORTKEY_API_KEY", provider="@lemonfox-ai")

image = portkey.images.generate(
    prompt="A cute baby sea otter",
    size="1024x1024"
)

print(image.data[0].url)

import Portkey from 'portkey-ai';

const portkey = new Portkey({
    apiKey: 'PORTKEY_API_KEY',
    provider: '@lemonfox-ai'
});

const image = await portkey.images.generate({
    prompt: "A cute baby sea otter",
    size: "1024x1024"
});

console.log(image.data[0].url);

Speech-to-Text

Transcribe audio with Whisper:

Python

from portkey_ai import Portkey

portkey = Portkey(api_key="PORTKEY_API_KEY", provider="@lemonfox-ai")

audio_file = open("/path/to/file.mp3", "rb")

transcription = portkey.audio.transcriptions.create(
    model="whisper-1",
    file=audio_file
)

print(transcription.text)

import Portkey from 'portkey-ai';
import fs from 'fs';

const portkey = new Portkey({
    apiKey: 'PORTKEY_API_KEY',
    provider: '@lemonfox-ai'
});

const transcription = await portkey.audio.transcriptions.create({
    file: fs.createReadStream("/path/to/file.mp3"),
    model: "whisper-1"
});

console.log(transcription.text);
