chatanywhere/GPT_API_free

This project offers free and paid API access to multiple large language models through a unified OpenAI-compatible protocol. It uses dynamic network acceleration so users in regions with connectivity restrictions can connect directly without a VPN, subject to daily request limits and non-commercial terms on free keys.

Project overview

Project type: Model Runtime
Deployment: Refer to project documentation
License: MIT

Best for

Individuals seeking personal, educational, or non-profit research access to multiple large language models without VPN configuration.

Key capabilities

Provides a free API key for accessing various models, subject to daily request limits.
Supports multiple large models via a unified OpenAI standard protocol.
Offers dynamic acceleration for domestic access without requiring a VPN.
Provides documentation for integrating the API with common software and plugins.

Limitations and risks

Free API keys are limited to 200 requests per day per IP and key.
The free API tier limits the quantity of input tokens per request.
Free API keys are strictly limited to personal, educational, or non-profit research use.
Because the service proxies third-party models, response times may be slower or requests may encounter errors originating from the upstream provider.

Getting started

Setup is straightforward: apply for a free API key, set the forwarding host in your OpenAI-compatible client, and begin sending text prompts.
