# Support Matrix Match a model to precision, GPU compute capability, GPU count, per-device video memory (VRAM), and system memory. Memory requirements use binary GiB: VRAM floors are per device, and system-memory floors are per host. The GPU inventory tables list nominal capacities in GB. ## Choose a Model Choose the model. The NIM selects a compatible profile and precision. Refer to [Precision Selection](deployment.md#precision-selection). | Runtime | Model | Supported Use | | --- | --- | --- | | Generator | `nano` | General-purpose Generator tasks | | Generator | `edge-droid` | DROID policy with action-only output; BF16 only; **experimental** | | Generator | `nano-droid` | DROID policy with action-only output; BF16 only | | Generator | `super` | General-purpose Generator tasks | | Generator | `super-t2i` | Full-step T2I only | | Generator | `super-t2i-4step` | Four-step T2I only | | Generator | `super-i2v` | Full-step I2V only | | Generator | `super-i2v-4step` | Four-step I2V only | | Reasoner | `edge` | Image/video reasoning; BF16 or FP8 only | | Reasoner | `nano` | Image/video reasoning | | Reasoner | `super` | Image/video reasoning | A Generator specialist rejects requests for other tasks. Edge has no general-purpose Generator. > **Experimental:** Edge-DROID policy is experimental in this release because > NVIDIA has not validated it. Validate its accuracy, latency, and safety > behavior for your workload before relying on it. After startup, follow [Verify the Selection](deployment.md#verify-the-selection). ### Practical Model Recommendation Start from the recommendation for your GPU class: - H200- and B200-class discrete GPUs: Use Super when the workload needs it, with `NIM_PERF_PROFILE=latency` for Generator. Leave precision, offload, tags, and profile ID unset. - H100, RTX PRO 6000 Blackwell, and lower-throughput discrete GPUs: Default to Nano, especially for video. Use Super only for an explicit model requirement. - Unified-memory systems (DGX Spark, Jetson AGX Thor): Default to Nano for both runtimes. Some Super Reasoner rows fit, but turnaround is impractical. - Smallest GPUs: Edge Reasoner and Edge-DROID have the lowest floors. Refer to [Edge Reasoner Verified GPUs](#edge-reasoner-verified-gpus). ## GPU Architecture and Topology Compatibility uses compute capability, per-device VRAM, and system RAM, not a GPU SKU allowlist: | Runtime | Precision | Minimum Compute Capability | | --- | --- | ---: | | Generator | BF16 | 8.0 | | Generator | FP8 | 8.9 | | Reasoner | BF16 | 8.0 | | Reasoner | FP8 | 8.9 | | Reasoner | NVFP4 | 10.0 | Use homogeneous GPUs. Mixed-GPU configurations are not supported, and Reasoner requires the same compute capability on every GPU. Do not add VRAM across devices. Each GPU in the selected layout must meet the floor in total and in free memory at startup. On a discrete GPU, Reasoner measures free memory after a 4-GiB runtime reserve (`NIM_GPU_MEMORY_HEADROOM_GIB`). On unified-memory systems, Generator uses only rows with **Model offload = None** and **Guardrails = Resident**. ### Unified-Memory Thresholds On unified-memory systems, **effective shared memory** is 70% of the device-reported total. The rest stays with the host. The same share is the default Reasoner `NIM_GPU_MEMORY_UTILIZATION`. | Runtime/Profile | Effective Shared-Memory Floor | Unified-Memory Policy | | --- | ---: | --- | | Generator `edge-droid` BF16 | 15 GiB | Resident model and guardrails | | Generator `nano` BF16; `nano-droid` BF16 | 58 GiB | Resident model and guardrails | | Generator `nano` FP8 | 44 GiB | Resident model and guardrails | | Generator `super` BF16 | 150 GiB | Resident model and guardrails | | Generator `super` FP8 | 93 GiB | Resident model and guardrails | | Reasoner `edge` BF16 or FP8 | 12 GiB/device | No CPU/model offload | | Reasoner `nano` BF16, FP8, or NVFP4 | 23.1 GiB/device | No CPU/model offload | | Reasoner `super` BF16, TP1 | 135 GiB/device | No CPU/model offload | | Reasoner `super` FP8, TP1 | 67 GiB/device | No CPU/model offload | | Reasoner `super` NVFP4, TP1 | 73 GiB/device | No CPU/model offload | Floors are compared with 70% of the binary-GiB total reported by the running system. Current free shared memory is checked separately at startup. ## Tested GPU Inventory This section lists devices in the release hardware inventory, grouped by architecture and sorted by nominal memory. Inventory membership does not mean every configuration is tested on that device, and devices outside it can be compatible when they meet the floors. ### Unified-Memory Systems Capacity is a shared host/device pool, not separate VRAM: | Device | Nominal Shared Memory | | --- | ---: | | Jetson AGX Thor T5000 | 123 GiB | | DGX Spark (GB10) | 128 GB (about 119 GiB) | The effective share is roughly 83 to 86 GiB. It fits the resident Generator Edge-DROID and Nano rows but no Super Generator row, and the Reasoner Edge, Nano, and Super FP8/NVFP4 TP1 rows. Reasoner Super BF16 TP1 (135 GiB) exceeds both systems' total capacity, so freeing cache cannot make it fit. ### NVIDIA Blackwell Ultra | GPU | Nominal GPU Memory | | --- | ---: | | GB300 Workstation | 252 GB HBM3e | | B300 SXM6 | 288 GB HBM3e | | GB300 | 288 GB HBM3e | ### NVIDIA Blackwell | GPU | Nominal GPU Memory | | --- | ---: | | GeForce RTX 5090 | 32 GB GDDR7 | | RTX PRO 4500 Blackwell Server Edition | 32 GB GDDR7 | | RTX PRO 6000 Blackwell Server Edition | 96 GB GDDR7 | | RTX PRO 6000 Blackwell Workstation Edition | 96 GB GDDR7 | | B200 | 192 GB HBM3e | | GB200 | 192 GB HBM3e | ### NVIDIA Hopper and Grace Hopper | GPU | Nominal GPU Memory | | --- | ---: | | H100 80 GB HBM3 | 80 GB HBM3 | | H100 PCIe | 80 GB HBM3 | | H100 NVL | 94 GB HBM3 | | GH200 480 GB | 96 GB HBM3 | | H20 | 96 GB HBM3 | | H200 | 141 GB HBM3e | | H200 NVL | 141 GB HBM3e | | GH200 144 GB HBM3e | 144 GB HBM3e | ### NVIDIA Ada Lovelace | GPU | Nominal GPU Memory | | --- | ---: | | L20 | 48 GB GDDR6 | | L40S | 48 GB GDDR6 | | RTX 6000 Ada Generation | 48 GB GDDR6 | ### NVIDIA Ampere | GPU | Nominal GPU Memory | | --- | ---: | | A100 SXM4 40 GB | 40 GB HBM2e | | A100 SXM4 80 GB | 80 GB HBM2e | Nominal memory only orders this inventory. For GH200 480 GB, 480 GB is CPU memory. The table shows HBM GPU memory. ## Generator Profiles The `super` rows in this table also apply to `super-t2i`, `super-t2i-4step`, `super-i2v`, and `super-i2v-4step`. Transfer thresholds apply only to the general-purpose `nano` and `super` variants. | Variant Group | Precision | Model Offload | Guardrails During Diffusion | GPUs | Generation Minimum VRAM/Device | System-Memory Floor | Transfer Minimum VRAM/Device | | --- | --- | --- | --- | ---: | ---: | ---: | ---: | | `edge-droid` (experimental) | BF16 | None | Resident | 1, 2, 4, 8 | 15 GiB | 16 GiB | Not supported | | `nano`, `nano-droid` | BF16 | None | Resident | 1, 2, 4, 8 | 58 GiB | 40 GiB | 64 GiB | | `nano` | BF16 | Layer | Offloaded | 1 | 31 GiB | 64 GiB | 35 GiB | | `nano` | FP8 | None | Resident | 1, 2, 4, 8 | 44 GiB | 35 GiB | 50 GiB | | `nano` | FP8 | Model | Resident | 1 | 38 GiB | 36 GiB | 44 GiB | | `nano` | FP8 | Layer | Resident | 1 | 32 GiB | 36 GiB | 38 GiB | | `nano` | FP8 | Layer | Offloaded | 1 | 31 GiB | 64 GiB | 35 GiB | | `super` | BF16 | None | Resident | 1, 2, 4, 8 | 150 GiB | 112 GiB | 160 GiB | | `super` | BF16 | Model | Resident | 1 | 93 GiB | 150 GiB | 99 GiB | | `super` | BF16 | Layer | Resident | 1 | 42 GiB | 150 GiB | 50 GiB | | `super` | FP8 | None | Resident | 1, 2, 4, 8 | 93 GiB | 76 GiB | 103 GiB | | `super` | FP8 | Model | Resident | 1 | 64 GiB | 80 GiB | 76 GiB | | `super` | FP8 | Layer | Resident | 1 | 38 GiB | 80 GiB | 50 GiB | Specialist variants (`nano-droid`, `edge-droid`, and `super-*`) use only the resident-guardrail rows of their base model. Multi-GPU rows use every GPU. A `latency` profile splits each request with guidance parallelism 2 and sequence parallelism `n_gpus / 2`. A `throughput` profile runs one engine replica per GPU, and there is no one-GPU `throughput` profile. To limit the GPU count, refer to [GPU Selection](configuration.md#gpu-selection). The 31-GiB Nano layer-offload rows target 32-GB client GPUs such as the GeForce RTX 5090, which does not meet their 35-GiB Transfer minimum. > **System memory:** Profile selection enforces each row's system-memory floor > (Generator and Reasoner) against host memory or a smaller container memory > limit. Treat the floors as minimums. Media processing, concurrency, and other > host workloads can need more. Unified-memory systems have no separate host RAM > requirement. Size them with > [Unified-Memory Thresholds](#unified-memory-thresholds). Leave offload and guardrail residency on automatic selection unless a configuration is validated for the deployment. ## Reasoner Profiles Reasoner does not use Generator latency/throughput or model-offload selectors: | Model | Precision | GPUs | Tensor Parallelism | Minimum VRAM/Device | System-Memory Floor | Minimum Compute Capability | | --- | --- | ---: | ---: | ---: | ---: | ---: | | `edge` | BF16 | 1 | 1 | 12 GiB | 8 GiB | 8.0 | | `edge` | FP8 | 1 | 1 | 12 GiB | 8 GiB | 8.9 | | `nano` | BF16 | 1 | 1 | 23.1 GiB | 24 GiB | 8.0 | | `nano` | FP8 | 1 | 1 | 23.1 GiB | 17 GiB | 8.9 | | `nano` | NVFP4 | 1 | 1 | 23.1 GiB | 17 GiB | 10.0 | | `super` | BF16 | 1 | 1 | 135 GiB | 72 GiB | 8.0 | | `super` | BF16 | 2 | 2 | 73 GiB | 72 GiB | 8.0 | | `super` | FP8 | 1 | 1 | 67 GiB | 43 GiB | 8.9 | | `super` | NVFP4 | 1 | 1 | 73 GiB | 33 GiB | 10.0 | System memory follows the note under [Generator Profiles](#generator-profiles). When BF16 is selected, Super prefers TP1 and can fall back to TP2 when TP1 lacks free memory. To require TP2, set `NIM_TAGS_SELECTOR='n_gpus=2,nim_tp=2'`. ## Edge Reasoner Verified GPUs Edge Reasoner was verified on these GPUs. Edge-DROID policy was not validated and is [experimental](#choose-a-model). Each deployment must still meet the floors above and the exact image manifest. | Architecture | GPUs | | --- | --- | | NVIDIA Blackwell Ultra | B300 SXM6, GB300 | | NVIDIA Blackwell | B200, GB200, DGX Spark (GB10), RTX PRO 6000 Blackwell Server Edition, RTX PRO 6000 Blackwell Workstation Edition, GeForce RTX 5090 | | NVIDIA Hopper and Grace Hopper | H100 80 GB HBM3, H100 PCIe, H100 NVL, H200, H200 NVL, H20, GH200 480 GB, GH200 144 GB HBM3e | | NVIDIA Ada Lovelace | L40S, RTX 6000 Ada Generation | | NVIDIA Ampere | A100 SXM4 40 GB, A100 SXM4 80 GB, A100 PCIe 40 GB, A100 80 GB PCIe | NVIDIA Ampere GPUs (compute capability 8.0) support only the BF16 Edge profiles. ## Transfer Headroom Transfer needs more peak memory than ordinary generation, so startup checks it separately. A deployment can serve generation while rejecting Transfer. Use a larger GPU or a lower-memory configuration. `NIM_ALLOW_UNSAFE_TRANSFER=1` bypasses the check for diagnosis only and can cause out-of-memory failures. ## Media and Codecs | Direction | Media | Documented Formats/Codecs and Limits | | --- | --- | --- | | Input | Images | Use the included JPEG, PNG, and WebP fixtures; verify other formats against the deployed image | | Input | Videos | MP4/MOV, Matroska/WebM, FLV, and AVI containers; H.264, H.265/HEVC, and MPEG-4 Part 2 decode through NVDEC, VP8, VP9, and AV1 use software decode; other codecs return HTTP 422 | | Output | Generator image | JPEG | | Output | Generator video | VP9 in MP4 | Inputs are base64 or data URLs.
