New AI API Proxy Boasts GPT-5.5 Compatibility and Low Cost with 0.065 Multiplier

New AI API Proxy Service Launched, Targeting Developers with GPT-5.5 Compatibility

On April 26, 2026, a new AI API relay service announcement on the tech community site V2EX created a buzz. This service, built on physical servers, acts as a proxy for the latest AI model, GPT-5.5, boasting an extremely low cost with a 0.065 multiplier. It has caught the attention of developers and AI users by promising high performance and cost-efficiency. Unlike typical cloud proxies, this service emphasizes the performance benefits of using physical servers, addressing the demand for reduced costs and easier access to AI development environments.

Overview and Technical Features of the Service

The service, launched under the name “MSU Tools,” highlights the following key features:

Firstly, it is built on physical servers (bare-metal servers) with a construction cost exceeding $100 per month. This sets it apart from proxies running on standard virtual private servers (VPS), as it aims to ensure stability and speed during high concurrency (simultaneous connections).

Secondly, it is fully compatible with the latest AI model, GPT-5.5, which is touted for its exceptional response speed. GPT-5.5, introduced by OpenAI in early 2026, represents the next generation of large language models (LLMs), featuring enhanced reasoning capabilities and multimodal support.

The service’s standout feature is its cost-effectiveness, with a 0.065 multiplier being its primary selling point. This translates to a 6.5% discount compared to OpenAI’s official rates. For instance, if OpenAI charges $1 for API usage, this service allows access for just 6.5 cents. As part of a promotional campaign, users who register using the promo code “V2EX” receive $5 in free credits. Additionally, posting on the forum grants users another $5, bringing the total to $10 in free credits. With the 0.065 multiplier applied, this equates to approximately $154 worth of GPT-5.5 usage (based on official rates).

The service also emphasizes full compatibility with popular AI-assisted development tools like Cursor, ClaudeCode, and OpenClaw. These tools are widely used for AI-supported coding assistance and code generation. The seamless integration with this proxy service offers a significant advantage, particularly for developers accessing overseas AI services from mainland China. The use of physical servers aims to reduce latency and improve connection stability for such users.
