 - `params` merge precedence (config): `agents.defaults.params` (global base) is overridden by `agents.defaults.models["provider/model"].params` (per-model), then `agents.list[].params` (matching agent id) overrides by key. See [Prompt Caching](/reference/prompt-caching) for details.
 - `params.extra_body`/`params.extraBody`: advanced pass-through JSON merged into `api: "openai-completions"` request bodies for OpenAI-compatible proxies. If it collides with generated request keys, the extra body wins; non-native completions routes still strip OpenAI-only `store` afterward.
 - `params.chat_template_kwargs`: vLLM/OpenAI-compatible chat-template arguments merged into top-level `api: "openai-completions"` request bodies. For `vllm/nemotron-3-*` with thinking off, OpenClaw automatically sends `enable_thinking: false` and `force_nonempty_content: true`; explicit `chat_template_kwargs` override those defaults, and `extra_body.chat_template_kwargs` still has final precedence.
+- `params.preserveThinking`: Z.AI-only opt-in for preserved thinking. When enabled and thinking is on, OpenClaw sends `thinking.clear_thinking: false` and replays prior `reasoning_content`; see [Z.AI thinking and preserved thinking](/providers/zai#thinking-and-preserved-thinking).
 - `embeddedHarness`: default low-level embedded agent runtime policy. Omitted runtime defaults to OpenClaw Pi. Use `runtime: "pi"` to force the built-in PI harness, `runtime: "auto"` to let registered plugin harnesses claim supported models, or a registered harness id such as `runtime: "codex"`. Set `fallback: "none"` to disable automatic PI fallback. Explicit plugin runtimes such as `codex` fail closed by default unless you set `fallback: "pi"` in the same override scope. Keep model refs canonical as `provider/model`; select Codex, Claude CLI, Gemini CLI, and other execution backends through runtime config instead of legacy runtime provider prefixes. See [Agent runtimes](/concepts/agent-runtimes) for how this differs from provider/model selection.
 - Config writers that mutate these fields (for example `/models set`, `/models set-image`, and fallback add/remove commands) save canonical object form and preserve existing fallback lists when possible.
 - `maxConcurrent`: max parallel agent runs across sessions (each session still serialized). Default: 4.

+    Z.AI thinking follows OpenClaw's `/think` controls. With thinking off,
+    OpenClaw sends `thinking: { type: "disabled" }` to avoid responses that
+    spend the output budget on `reasoning_content` before visible text.
+
+    Preserved thinking is opt-in because Z.AI requires the full historical
+    `reasoning_content` to be replayed, which increases prompt tokens. Enable it
+    per model:
+
+    ```json5
+    {
+      agents: {
+        defaults: {
+          models: {
+            "zai/glm-5.1": {
+              params: { preserveThinking: true },
+            },
+          },
+        },
+      },
+    }
+    ```
+
+    When enabled and thinking is on, OpenClaw sends
+    `thinking: { type: "enabled", clear_thinking: false }` and replays prior
+    `reasoning_content` for the same OpenAI-compatible transcript.
+
+    Advanced users can still override the exact provider payload with
+    `params.extra_body.thinking`.
