	OfoxAI: Text, image, and video AI in one platform OfoxAI is a unified AI API platform bringing together text, image, and video models from multiple providers. With OpenAI-compatible endpoints and native Anthropic and Gemini interfaces, developers can access models for AI applications, agents, and content creation through one platform.

	One entry point to connect and manage the world's leading AI models Fluxion AI serves individual developers, technical teams, and enterprises with a unified API for connecting to and managing leading AI models worldwide. Dynamic multi-route scheduling improves availability, while model performance, response times, and costs remain transparent and easy to review. Depending on the model and route, API calls can cost 40%–98% less than official or benchmark prices. Visit and sign up now to receive $7 in API credits. (Dedicated link)
	Protect and accelerate websites and APIs, serving users in mainland China and around the world, and extend acceleration and security capabilities to native/mobile apps through a client SDK — self-built private-deployment CDN | subscription-based high-protection CDN | an independently controllable, flexibly composable CDN network.
	Thanks to APIMart for sponsoring this project! APIMart is a low-cost API platform for AI image & video generation — GPT-Image-2 from $0.006/image, 160+ images per dollar. One async API covers both image and video: submit a task, get an ID, fetch results via polling or callback. Batch tens of thousands of images without timeouts, switch models without changing code.

Why GPT-Load

Your application only needs one base URL and one AccessKey. Providers, accounts, credentials, models, and routing policy are all configured in the management UI.

• One gateway, native protocols — Manage official APIs, cloud platforms, model services, and compatible relays together while clients keep their OpenAI, Anthropic, or Gemini native interfaces.
• One mechanism for API keys and subscriptions — Codex, Claude, Antigravity, Grok, and API-key channels share credential management, scheduling, and health handling.
• Scheduling and failure isolation built in — Multi-credential scheduling, configurable weights, retries, cooldown, blacklisting, and session affinity reduce the impact of overloaded or failing credentials.
• Observable, self-hosted, and simple to deploy — Inspect health, routes, logs, usage, and cost estimates in an embedded UI backed by SQLite, MySQL, or PostgreSQL with local credential encryption.

Quick start

[!WARNING] If you are using 1.x, read Moving from 1.x first. 2.0 cannot open, import, or migrate 1.x data in place.

1. Start the service

Requires Docker and Docker Compose.

git clone --depth 1 https://github.com/tbphp/gpt-load.git
cd gpt-load

cp .env.example .env
docker compose up -d

Confirm the service is up:

curl --fail http://127.0.0.1:3001/health

The first start generates a management key. Read it and store it safely:

docker compose exec gpt-load sh -c 'cat /app/data/auth.key'

Open and sign in to the console with that key.

You can also set AUTH_KEY explicitly in .env before starting. By default the service listens on the loopback address only and is not exposed to the internet.

2. Initial configuration

Initial setup takes three steps:

1. Add a channel — Choose an upstream service and add one or more API keys. For subscription channels, complete the OAuth flow or import credentials as prompted.
2. Create a group — Pick a channel, then configure available models and runtime policy.
3. Create an AccessKey — Set the groups and client protocols it may use, then give the generated AccessKey to your application.

Screenshots

Groups — View channels, models, credential counts, and health in one place

Subscription accounts — Track account availability, quota windows, reset times, and runtime diagnostics

AccessKey read-only home — Sign in with an AccessKey to view only its own groups, models, requests, usage, and cost allowance

Usage and cost — Review request trends, cache hit rate, token categories, and cost estimates

Scope

Client protocols

Each channel declares exactly which protocols and capabilities it can execute. GPT-Load converts between su
