Recent personal best: A marathon-length journey across Beijing!
Hamer woke up a little earlier than usual this morning. After tossing and turning for a while, she said she wanted to check for presents. She padded into the living room and returned a moment later, announcing with quiet certainty that Santa had really brought her a Little Genius watch.
Merry Christmas
My Year in Poetry
This year, you let your thoughts flow into rivers, Weaving maps and intelligence into song.
From the faint glimmer of NMEA to the blazing fire of Magentic, Every line of code carried quiet determination. Through exploration, you measured the world— And, along the way, discovered yourself.

It’s too cold to take an e-bike ride in the winter in Beijing if you forget to bring a pair of gloves.
There are two ways to customise the models used by Claude Code.
This is a quick setup using environment variables for the API token and base URL.
On macOS, edit your shell configuration file: vim ~/.zshrc.
Add the following aliases:
alias claude="$HOME/.claude/local/claude"
export PATH="$HOME/.claude/local:$PATH"
alias kimi="ANTHROPIC_AUTH_TOKEN=<api-key> ANTHROPIC_BASE_URL=https://api.moonshot.cn/anthropic claude"
export PATH="$HOME/.claude/local:$PATH"
alias bigmodel="ANTHROPIC_BASE_URL=https://open.bigmodel.cn/api/anthropic ANTHROPIC_AUTH_TOKEN=<api-key> claude"
export PATH="$HOME/.claude/local:$PATH"
alias minimax="ANTHROPIC_BASE_URL=https://api.minimaxi.com/anthropic ANTHROPIC_AUTH_TOKEN=<api-key> claude"
This approach is lightweight and convenient when you only need to switch endpoints or tokens quickly.
This method allows you to configure Claude Code with complete, reusable environments.
Steps:
Under the ~/.claude directory, create a models folder to store configuration files for different models.
bigmodel.json
{
"env": {
"ANTHROPIC_AUTH_TOKEN": "<api-key>",
"ANTHROPIC_BASE_URL": "https://open.bigmodel.cn/api/anthropic",
"API_TIMEOUT_MS": "3000000",
"CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC": 1
}
}
kimi.json
{
"env": {
"ANTHROPIC_BASE_URL": "https://api.moonshot.cn/anthropic",
"ANTHROPIC_AUTH_TOKEN": "<api-key>",
"ANTHROPIC_MODEL": "kimi-k2-thinking-turbo",
"ANTHROPIC_DEFAULT_OPUS_MODEL": "kimi-k2-thinking-turbo",
"ANTHROPIC_DEFAULT_SONNET_MODEL": "kimi-k2-thinking-turbo",
"ANTHROPIC_DEFAULT_HAIKU_MODEL": "kimi-k2-thinking-turbo",
"CLAUDE_CODE_SUBAGENT_MODEL": "kimi-k2-thinking-turbo"
}
}
minimax.json
{
"env": {
"ANTHROPIC_BASE_URL": "https://api.minimaxi.com/anthropic",
"ANTHROPIC_AUTH_TOKEN": "<api-key>",
"API_TIMEOUT_MS": "3000000",
"CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC": 1,
"ANTHROPIC_MODEL": "MiniMax-M2.1",
"ANTHROPIC_SMALL_FAST_MODEL": "MiniMax-M2.1",
"ANTHROPIC_DEFAULT_SONNET_MODEL": "MiniMax-M2.1",
"ANTHROPIC_DEFAULT_OPUS_MODEL": "MiniMax-M2.1",
"ANTHROPIC_DEFAULT_HAIKU_MODEL": "MiniMax-M2.1"
}
}
Edit ~/.zshrc again: vim ~/.zshrc.
alias cc-kimi="claude --settings $HOME/.claude/models/kimi.json"
alias cc-bigmodel="claude --settings $HOME/.claude/models/bigmodel.json"
alias cc-minimax="claude --settings $HOME/.claude/models/minimax.json"
This approach is ideal when you need fine-grained control, consistent defaults, or multiple model profiles.
Before going to the bathroom in the morning, Hamer deliberately ran to the windowsill to check whether it had snowed. Seeing nothing. When we were ready to leave for school and stepped outside, we noticed snow resting on the electric scooter. It turned out the snow had fallen quietly overnight.
This morning, I tried to do Hamer’s bun hairstyle. At first, I wasn’t sure how to make it work. Then I tried putting on a hair net first, and to my surprise, it worked—though it was a bit loose. I had failed many times before and could never get the hair to stay up.
The weather was great today, and I made a spontaneous decision to go for a run in the afternoon. I ran along the eastern side of the Second Ring greenway all the way to the Temple of Heaven to meet Xiaoyan and Hamer, who were watching a ballet performance.
Beijing saw its first snowfall of the year today. What began as light snow around noon continued through the evening and slowly built up. By nighttime, the city was covered in white, thick enough to make a snowball fight possible.
