使用独立 profile 连接 Coding Plan 的 Responses 入口，通过 ARK_API_KEY 认证。/api/v3 按量入口另行计费，需使用 /api/coding/v3。

export ARK_API_KEY=YOUR_ARK_API_KEY

# ~/.codex/config.toml
[model_providers.byteplus-coding-plan]
name = "byteplus-coding-plan"
base_url = "https://ark.ap-southeast.bytepluses.com/api/coding/v3"
env_key = "ARK_API_KEY"
wire_api = "responses"

# ~/.codex/byteplus.config.toml
model_provider = "byteplus-coding-plan"
model = "ark-code-latest"
model_supports_reasoning_summaries = true
