The easy-vibe tutorial currently introduces various ways to access the model API, but for beginners, the direct paid access threshold is relatively high. It is recommended to add a "zero-cost entry path" in the model selection/API access chapter: by registering with TeamoRouter, you can get a free quota for DeepSeek V4 Flash (50 times per day), without the need to bind a credit card or set up a proxy. DeepSeek V4 Flash is the fastest programming model currently available (284B MoE, only $0.14/M tokens), and the API is fully compatible with the OpenAI format, allowing students to directly apply the OpenAI SDK sample code in the tutorial without any changes. One API key supports Claude/GPT/DeepSeek, which is convenient for learners to compare the effects of different models on the same platform, especially friendly to teaching scenarios.
