@@ -182,3 +184,46 @@ prepared requests retain independent backing. If the uncached suffix skips the
 image entirely, it needs no vision encoding; if it intersects the image, that
 backing may still encode the full image before selecting the remaining rows.
 Prefix identity does not retain RGB or embedding buffers.
+
+## CUDA
+
+The CUDA worker builds `CudaExecutor` through `CudaExecutorConfig` under the same
+serving runtime, prefix cache, scheduler and launcher. Export with the off-graph
+cache, which on CUDA writes the batching methods: static `forward_{N}` (each
+captured into a CUDA graph), a dynamic `forward_others` for wider steps, and
+device samplers. Without `--use-offgraph-kv-cache` CUDA keeps its in-graph
+prefill and decode export.
+
+```sh
+python -m executorch.examples.models.muse_glimmer.export.export_solo \
+  --backend cuda \
+  --gguf /path/to/models/mg/model.gguf \
+  --use-offgraph-kv-cache \
+  --output-dir /path/to/models/mg-batching-cuda
+```
+
+`--forward-sizes` (default `1,2,4,8,16,32,64`), `--max-step-tokens` (default
+4096) and `--max-cells` (default 65536) size the methods and the shared KV
+pool; `--logits` samples on the host instead. The artifact is text only, so
+`--mmproj` is rejected.
+
+Build with `make muse-glimmer-batching-cuda` on Linux, then serve:
+
+```sh
+python -m executorch.examples.models.muse_glimmer.serving.serve_batching \
+  --backend cuda \
+  --worker-bin /path/to/executorch/cmake-out/examples/models/muse-glimmer-batching/muse_glimmer_batching_worker \
+  --model-path /path/to/models/mg-batching-cuda/model.pte \
+  --data-path /path/to/models/mg-batching-cuda/aoti_cuda_blob.ptd \
+  --tokenizer-path /path/to/models/mg/tokenizer.json \
+  --hf-tokenizer /path/to/models/mg \
+  --max-context 8192
+```
+
+`--data-path` is required and `--pos-embed-path` is rejected; image requests
+fail preparation. Every resident session reserves `--max-context` cells of the
+pool: requests, `--prefix-cache-entries` snapshots, and one capture lane when
+snapshots are enabled. Their total reservation must leave one cell for padded
+writes within the exported `--max-cells`.
+The cell pool tracks at most 64 resident sessions. Prefix snapshots clone a
+session's cells by reference, sharing the prompt's KV rather than copying it.
