Reddit 排障：升级后 Claude Opus 4.6 报 Unknown model 的恢复流程
问题/场景：升级后会话报 `Unknown model: anthropic/claude-opus-4-6`。前置条件：具备网关与模型配置权限。实施步骤：先确认模型列表变化、执行 doctor/status、在 configure/models 中切换受支持模型并回归。关键命令：`openclaw doctor`、`openclaw models list`、`openclaw configure --section models`。验证：原失败会话可恢复执行。风险：盲目强行写旧模型 ID 会持续失败。

Prerequisites
- Gateway is reachable and you can edit model defaults/allowlist.
- You can capture exact failing model id from logs or error text.
Steps
- Run `openclaw doctor` and `openclaw models list` to confirm currently available Anthropic models.
- Open model config and replace deprecated/unknown IDs with supported aliases or provider/model entries.
- Restart gateway if needed, then retry the same task from the previously failing session.
- Document migration mapping (old ID -> new ID) for future upgrades.
Commands
openclaw doctoropenclaw models listopenclaw configure --section modelsopenclaw gateway restartVerify
The previously failing request completes successfully and no further Unknown model errors appear for the migrated path.
Caveats
- If provider removes/deprecates a model, local config fix alone cannot restore it.
- Community thread is anecdotal; confirm against official model matrix/release notes（需验证）.
