Want to try the 671B full-spec Deepseek-r1 for free with web and API access? There aren't many options available!

• deepseek.com official: Free web version with the best performance, no free API quota, and currently paused top-ups.
• ByteDance Volcano Ark / Silicon-based Flow: Offer full-spec R1 and API, but no free quota.
• Baidu Intelligent Cloud Qianfan ModelBuilder: Provides full-spec R1 and API for free for a limited time, but the interface is not compatible with OpenAI, making it inconvenient.
• 302.ai and other cloud providers: Mostly offer partial free quotas for the web version but no free API quota.

After comprehensive testing, the only platforms I found that offer sufficient free quota, full-spec R1, and OpenAI-compatible API access are: Tencent Cloud Ti Platform and Alibaba Cloud Bailian.
