Want a free trial of the full-blood 671B Deepseek-r1 with web interface and API access? There aren't many options!

• deepseek.com official: The web version is free with the best performance, but there's no free API quota and recharge is currently suspended.
• ByteDance Volcano Engine/Silicon Flux, etc.: Provide the full-blood R1 version and API, but no free quota.
• Baidu AI Cloud Qianfan ModelBuilder: Offers the full-blood R1 version and API for a limited time, but the interface is not compatible with OpenAI, making it inconvenient to use.
• 302.ai and other cloud service providers: Basically provide a web version with some free quota, but no free API quota.

After comprehensive experience, I have only found Tencent Cloud Ti Platform and Alibaba Cloud Bailian that truly have sufficient free quota and provide full-blood R1 and OpenAI API compatible calls.
