Limitations#

All models
- Prompts with Unicode characters in the range from 0x0e0020 to 0x0e007f can produce unpredictable responses. You should filter these characters out of a prompt before submitting the prompt to the VLM.
- When environment variable NIM_DISABLE_LOG_REQUESTS=0, the prompt_token_ids and prompt fields are empty in Completions API responses; prompt_token_ids is also empty in Chat Completions API responses.
Gemma 4 31B Instruct
- GPUs built on the ARM architecture are not supported.
- This model is built with a specialized base container and is subject to limitations. It uses the release tag 1.7.0-variant for the container image. Refer to Notes on NIM Container Variants for more information.
Mistral-Small-4-119B-2603
- This model is built with a specialized base container and is subject to limitations. It uses the release tag 1.7.0-variant for the container image. Refer to Notes on NIM Container Variants for more information.
- The ARM architecture is not supported.
- Only text and image inputs are supported.
Qwen3.5-35B-A3B
- This model is built with a specialized base container and is subject to limitations. It uses the release tag 1.7.0-variant for the container image. Refer to Notes on NIM Container Variants for more information.
- The /v1/responses endpoint is currently not supported.
- Under high-concurrency video workloads, the model may experience video decoding resource saturation, which can result in performance degradation at elevated concurrency levels.
- When mounting a cache directory from the host system, add -u $(id -u), -e HOME=/tmp, and -e USER=$(id -un) to the docker run command to avoid potential permission issues.
Qwen3.5-122B-A10B
- This model is built with a specialized base container and is subject to limitations. It uses the release tag 1.7.0-variant for the container image. Refer to Notes on NIM Container Variants for more information.
- The /v1/responses endpoint is currently not supported.
- Under high-concurrency video workloads, the model may experience video decoding resource saturation, which can result in performance degradation at elevated concurrency levels for video workloads.
- On NVIDIA H100 SXM, the NIM_MAX_BATCH_SIZE parameter is limited to 128. Increasing this value may result in out-of-memory errors in the Mamba layer state cache.

If video input support is not required, disable video input by setting NIM_MAX_VIDEOS_PER_PROMPT=0 for optimal performance.
- When mounting a cache directory from the host system, add -u $(id -u), -e HOME=/tmp, and -e USER=$(id -un) to the docker run command to avoid potential permission issues.
- When running on H100 GPUs, manually set the environment variable NIM_MANIFEST_PROFILE.

- Sending an invalid value for the mm_processor_kwargs parameter results in an HTTP 500 error code.
- The function role is not supported in the messages field. The supported roles are system, user, assistant, and tool.
- On L40S GPUs, maximum context length is 100k due to limited GPU memory. Other GPUs support up to 262,144 tokens.

Mistral Large 3 675B Instruct 2512
- For Mistral models, you cannot change the guided decoding backend. The environment variable NIM_GUIDED_DECODING_BACKEND is set to guidance by default and is not configurable.
- For Mistral models, you cannot override chat_template at the request level using the chat_template or chat_template_kwargs parameter.
