It acts as a reverse proxy, routing requests to ChatGPT while maintaining full compatibility with OpenAI's SDK interface, allowing any application or tool that supports a custom base URL and API key to connect. The service offers a free tier that provides access to ChatGPT models for chat, image generation, and voice dialogue without requiring an official subscription, along with a paid tier that unlocks over 130 OpenAI models including GPT-4 with lower latency and reduced pricing. Both tiers support streaming chat responses, delivering output incrementally as it is generated for real-time display. The proxy integrates with a wide range of clients, including official OpenAI SDKs for Python and Node.js, open-source web chat interfaces, desktop tools, and third-party applications. It also supports connecting knowledge-base-enabled chat applications for context-aware conversations, and enforces rate limiting on the free tier to manage usage. ## Tags ### Artificial Intelligence & ML - [ChatGPT API Access](https://awesome-repositories.com/f/artificial-intelligence-ml/artificial-intelligence-tooling/free-access-utilities/chatgpt-api-access.md) — Provides free access to ChatGPT models through an OpenAI-compatible API endpoint without requiring an official subscription. - [OpenAI-Compatible APIs](https://awesome-repositories.com/f/artificial-intelligence-ml/agentic-systems-frameworks/model-integration-serving/model-integration-interfaces/ai-integration-apis/openai-compatible-apis.md) — Forwards requests to ChatGPT models using the same interface as OpenAI's official API. - [Streaming Chat Responses](https://awesome-repositories.com/f/artificial-intelligence-ml/ai-chat-clients/streaming-chat-responses.md) — Delivers chat output incrementally as it is generated for real-time display. - [OpenAI-Compatible](https://awesome-repositories.com/f/artificial-intelligence-ml/artificial-intelligence-tooling/agent-and-tool-integrations/api-servers/openai-compatible.md) — Adheres to OpenAI's SDK interface by accepting identical base URLs, API keys, and request schemas. ### Networking & Communication - [ChatGPT](https://awesome-repositories.com/f/networking-communication/api-proxies/chatgpt.md) — Acts as a reverse proxy that routes requests to ChatGPT while maintaining full compatibility with OpenAI's SDK interface. ### DevOps & Infrastructure - [Free AI API Endpoints](https://awesome-repositories.com/f/devops-infrastructure/rest-api-endpoint-management/single-endpoint-apis/free-ai-api-endpoints.md) — Provides a free API endpoint that allows applications to send chat, image, and voice requests to ChatGPT models. ### Web Development - [API Proxies](https://awesome-repositories.com/f/web-development/api-proxies.md) — Maps incoming requests to OpenAI's API format and forwards them to ChatGPT, returning responses in the same structure. - [Free ChatGPT](https://awesome-repositories.com/f/web-development/api-proxies/free-chatgpt.md) — Provides free access to ChatGPT models through an OpenAI-compatible endpoint without requiring an official subscription. - [Chat API Integrations](https://awesome-repositories.com/f/web-development/third-party-api-integrations/chat-api-integrations.md) — Enables third-party chat apps, desktop tools, and web UIs to use ChatGPT by configuring a custom API endpoint and key. - [API Proxy Routings](https://awesome-repositories.com/f/web-development/traffic-routing/frontend-version-routing/api-proxy-routings.md) — Routes API calls through a server that intercepts and redirects traffic to ChatGPT's backend. - [Third-Party API Integrations](https://awesome-repositories.com/f/web-development/third-party-api-integrations.md) — Works with any application that supports a custom OpenAI-compatible API endpoint and base URL.
