Connection troubleshooting

The original guide suggests excluding local addresses from your proxy with the command for your operating system.

Windows:

setx NO_PROXY "127.0.0.1,localhost"

macOS:

 echo 'export NO_PROXY=127.0.0.1,localhost' >> ~/.zshrc && source ~/.zshrc

My rating: Excellent.

The selection of free models is limited and changes over time. My earlier notes mention free DeepSeek V4 access; the listing later included Zhipu models.

My rating: Excellent.

My notes describe a daily window of free, unlimited DeepSeek V4 Flash usage, apparently lasting about three hours. Availability varies by region.

On August 19, 2026, access was unavailable from Hong Kong in my experience; switching to a US connection restored it. Other regions, such as India, may also have different availability.

My rating: Excellent.

In my experience, this platform offers genuinely unlimited free usage for selected models. The selection changes; my notes include Kimi v3, DeepSeek V4 Pro, Qwen3.8 Max, and GLM.

I have seen garbled output with long agent conversations. Tasks can still complete, but the final response may be difficult to read. Asking the agent to rewrite the response has sometimes helped.

I used this API with Hermas agent. One workaround is to ask the agent to remember to regenerate a response whenever its output becomes garbled.

The main drawback in my testing was readability of the output.

My rating: Great.

There are some limits and the free model selection is small, but responses were very fast in my experience.
