购买 GPT 订阅套餐目前会赠送 Grok 套餐，自动到账。订阅分组选「Grok 文本大模型」，可用 grok-4.6。key 用 Grok 按量分组或订阅分组。

在 Grok Build 里用

把 CHAINFUEL_GROK_API_KEY 写进 ~/.zshrc。~/.grok/config.toml：

[cli]
installer = "internal"

[ui]
max_thoughts_width = 120
fork_secondary_model = "grok-build"
yolo = false
compact_mode = false
permission_mode = "always-approve"

[models]
default = "chainfuel-grok-4.5"
default_reasoning_effort = "low"

[model."chainfuel-grok-4.5"]
model = "grok-4.5"
base_url = "https://chainfuel.tap365.org/v1"
name = "Grok 4.5 via ChainFuel"
description = "Grok 4.5 through ChainFuel OpenAI-compatible endpoint"
env_key = "CHAINFUEL_GROK_API_KEY"
api_backend = "responses"
context_window = 256000

[marketplace]
default_skills_installs_purged = true

在 Codex 里用

平台兼容 Codex 流式调用。只改 config.toml 和 auth.json，Base URL 不变。

model = "grok-4.5"
review_model = "grok-45"
model_catalog_json = "./model-catalog.json"

{
  "OPENAI_API_KEY": "你的grok分组的key"
}

如果出现 Model metadata for grok-4.5 not found，把 metadata 文件放到 Codex 配置目录，和 config 同级。这个警告不影响使用。GPT 客户端对非 GPT 模型都会提示。

用 skill 调用

https://github.com/kcd-dev/grok-skill

把项目交给 Codex 装好即可。可以说：让 Grok 评审、给第二意见、做架构、做 code review、做风险分析。
