DeepSeek V4 Flash utility
Run the user's task on opencode-go/deepseek-v4-flash with the Codex CLI:
codex exec -m opencode-go/deepseek-v4-flash -s workspace-write --skip-git-repo-check --ephemeral -C . "<task>"
Choose the sandbox based on the task: read-only for inspection, workspace-write for edits.
When the task is part of the self-improving loop, run the loop driver with
--runner-model opencode-go/deepseek-v4-flash instead.
