gpt-image-2 Reverse API Key Takeaways

What exactly is a Reverse API?

A Reverse API (reverse-engineered API) is a channel that provides services via standard API protocols by reverse-engineering official web or internal interfaces when the official API is unavailable or restricted. It is not an official OpenAI product, but a technical solution implemented by third-party platforms based on web sessions, cookies, and request simulation.

For gpt-image-2, there are very few channels that can truly provide a stable Reverse API. The gpt-image-2-all released by APIYI is one of the most transparent and publicly available reverse-engineered solutions, with complete technical documentation available at docs.apiyi.com/en/api-capabilities/gpt-image-2-all/overview.

gpt-image-2 Reverse API Quick Start

Minimalist Example (Text-to-Image)

Here is the simplest way to make a call; you can generate an image with just 10 lines of code:

import openai

client = openai.OpenAI(
    api_key="YOUR_APIYI_KEY",
    base_url="https://vip.apiyi.com/v1"
)

response = client.images.generate(
    model="gpt-image-2-all",
    prompt="A cyberpunk-style Tokyo night scene, with neon signs written in Chinese saying 'The future is here'"
)
print(response.data[0].url)

import openai
import base64
from pathlib import Path
from typing import Optional

client = openai.OpenAI(
    api_key="YOUR_APIYI_KEY",
    base_url="https://vip.apiyi.com/v1",
    timeout=120,  # Official recommendation is ≥120s, gpt-image-2 generation takes about 30s
)

def text_to_image(prompt: str, save_path: str = "output.png") -> str:
    """Text-to-image: Generate images via apiyi gpt-image-2-all"""
    try:
        resp = client.images.generate(
            model="gpt-image-2-all",
            prompt=prompt,
            response_format="url",
        )
        image_url = resp.data[0].url
        return image_url
    except openai.APIError as e:
        print(f"API Error: {e}")
        return ""

def image_to_image(
    reference_image: str,
    edit_prompt: str,
    save_path: str = "edited.png"
) -> Optional[str]:
    """Image-to-image: Edit based on a reference image, supports single/multi-image fusion"""
    with open(reference_image, "rb") as f:
        resp = client.images.edit(
            model="gpt-image-2-all",
            image=f,
            prompt=edit_prompt,
            response_format="b64_json",
        )
    b64_data = resp.data[0].b64_json
    if b64_data.startswith("data:image"):
        b64_data = b64_data.split(",", 1)[1]
    Path(save_path).write_bytes(base64.b64decode(b64_data))
    return save_path

# Usage example
url = text_to_image("A 16:9 landscape AI summit promotional poster, with the main title 'AI Summit 2026'")
print(f"Image URL: {url}")

edited = image_to_image(
    reference_image="./original.png",
    edit_prompt="Replace the background with a spring garden in full cherry blossom bloom, keeping the character's pose unchanged",
)
print(f"Edited image: {edited}")

gpt-image-2 Reverse API Channel Comparison

Channel Analysis

OpenAI Official API Analysis: The official channel leads in compliance and long-term stability. However, as of late April 2026, access is primarily for enterprise and ChatGPT Plus/Team subscribers. Most small and medium-sized developers face wait times until after May, and token-based pricing is significantly higher. In contrast, APIYI's reverse channel gpt-image-2-all is better suited for validation and small-to-medium production scenarios in terms of availability and cost.

fal Enterprise API Analysis: fal launched its enterprise-grade endpoint for gpt-image-2 on April 21, 2026, performing well in high-concurrency and SLA guarantees. However, it targets enterprise clients, requiring agreements and prepayments, which is unfriendly to independent developers. For teams needing to quickly validate gpt-image-2 capabilities, APIYI's reverse channel is faster and cheaper.

Other Proxy Channel Analysis: There are other small proxy services offering gpt-image-2 access, but they generally suffer from opaque pricing, high failure rates, and lack of documentation. By comparison, APIYI provides complete technical documentation at docs.apiyi.com and explicitly promises "no charges for failed requests," making it more trustworthy in terms of transparency and stability.

Note on Comparison: The price and availability data above are sourced from official OpenAI announcements, fal enterprise API releases, and official APIYI documentation. You can verify this by testing on the APIYI (apiyi.com) platform.

Capabilities of gpt-image-2-all

Based on the official documentation at docs.apiyi.com/en/api-capabilities/gpt-image-2-all/overview, this model supports three core endpoints:

Important Parameter Restrictions

The gpt-image-2-all model uses a different parameter system than traditional DALL-E or gpt-image-1. The following parameters will be ignored; please do not include them to avoid validation errors:

• size: Explicit size parameters are not supported. Composition is controlled by natural language in the prompt (e.g., "1024×1024 square", "16:9 banner").
• n: Only one image is returned per request; for multiple images, please use concurrent calls.
• quality: Uses a unified quality standard; there are no "hd" or "standard" tiers.
• aspect_ratio: Aspect ratio is also controlled via the prompt.

Reference Image Upload Guidelines

• Supported Formats: PNG / JPG / WebP
• Maximum Size: ≤ 10MB
• Return Format: url (R2 CDN link, valid for approximately 24 hours) or b64_json (includes built-in prefix).
• Generation Time: Approximately 30 seconds; we recommend setting your client timeout to ≥ 120 seconds.
