[None][doc] Update GLM-5 docs for GLM-5.3 and disaggregated serving - #18388
Conversation
- Add GlmMoeDsaForCausalLM row to the model-feature support matrix (CUDA Graph, MTP, and disaggregated serving validated) - List GLM-5.2/GLM-5.3 in the supported-models tables; GLM-5.3 is a weight update over GLM-5.2 with the same architecture and code path - Deployment guide: point to the GLM-5.3 checkpoints and note the checkpoint naming flip (zai-org/GLM-5.3 is the FP8 repo), add a validated-features list and a disaggregated serving section, and document the chat template changes (enable_thinking replaced by clear_thinking, reasoning_effort low/high) - Fix the architecture claim: GLM-5 is served through GlmMoeDsaForCausalLM, not DeepseekV32ForCausalLM Signed-off-by: Brian Nguyen <brnguyen@nvidia.com>

In `@docs/source/deployment-guide/deployment-guide-for-glm-5-on-trtllm.md`:
- Line 9: Correct the GLM-5.3 migration note in the deployment guide: state that
clear_thinking controls retention of prior reasoning rather than replacing
enable_thinking, and that generation always begins with <think>. Document
reasoning_effort values low, high, and max with max as the default, and explain
when chat requests should set clear_thinking=true.
- Line 151: Update the GLM-5 deployment launch command to set the served model
name to the documented model ID, ensuring the model listing and response
metadata use zai-org/GLM-5.3 consistently with the request, sample response, and
benchmark.
- Around line 175-177: Update both worker configurations in the deployment guide
to include transceiver_runtime: PYTHON alongside their cache transceiver
settings, ensuring GLM DSA KV-cache transfer uses the Python transceiver.

The GLM-5 family (GLM-5, GLM-5.2, GLM-5.3) is served through the GlmMoeDsaForCausalLM architecture, which is first registered in TensorRT-LLM 1.3.0rc9. The 1.3.0rc8 image cannot load these checkpoints, so update the minimum-version note and the container tag in the docker run example to 1.3.0rc9. Signed-off-by: Brian Nguyen <brnguyen@nvidia.com>
Verification notes for the version bump and the disaggregated-serving configMinimum version rc8 → rc9. GLM-5's checkpoints declare NIXL-only disaggregated config is sufficient.
This path is present as of 1.3.0rc9. |
Update the minimum-version note and the docker run container tag in the GLM-5 deployment guide from 1.3.0rc9 to 1.3.0rc25. Signed-off-by: Brian Nguyen <brnguyen@nvidia.com>

Description
Updates GLM-5 support documentation for GLM-5.3.
GLM-5.3 is a weight update over GLM-5.2 with the same architecture (
GlmMoeDsaForCausalLM) and code path. Verified against the HF checkpoints:config.jsonis identical across 5.2/5.3 on all model keys, and the weight maps have the same 59,585 tensor names and identical total size.Changes:
