Show HN: RigCheck – can your GPU or Mac run this open model? Sourced, open data

RigCheck launched as an open-data tool that tells users whether a given GPU or Mac can run a specific open AI model, drawing on developers' published requirements and benchmarks rather than measured tests. The site covers 13 models across 1 engine and 5 VRAM pages, and reports that a GeForce RTX 3060 (12 GB) with 32 GB RAM fits Gemma 4 12B (Q5_K_M), Gemma 4 E2B (BF16), Gemma 4 E4B (Q8_0) and Qwen3.8-27B (UD-IQ2_XXS) with every layer in GPU memory, while an RTX 3090 or 3090 Ti (24 GB) with 64 GB RAM fits six model sizes fully on the GPU. RigCheck labels these as capacity estimates for llama.cpp at a 32K context in the finder's quick mode, not measured setups, and notes that image and video models are judged by planning budgets and published recipes.

Can your GPU or Mac run this AI model? New open models ship every week. Pick your graphics card or Mac and RAM, and each model's own checker answers from the developers' published requirements and benchmarks. Short answer: With GeForce RTX 3060 12 GB + 32 GB RAM, Gemma 4 12B https://localrigcheck.com/gemma-4/ Q5 K M , Gemma 4 E2B https://localrigcheck.com/gemma-4/ BF16 , Gemma 4 E4B https://localrigcheck.com/gemma-4/ Q8 0 , Qwen3.8-27B https://localrigcheck.com/qwen-3-8-27b/ UD-IQ2 XXS fit with every layer in GPU memory; with GeForce RTX 3090 / 3090 Ti 24 GB + 64 GB RAM, Gemma 4 12B https://localrigcheck.com/gemma-4/ Q8 0 , Gemma 4 26B-A4B https://localrigcheck.com/gemma-4/ UD-Q4 K XL , Gemma 4 31B https://localrigcheck.com/gemma-4/ IQ4 XS , Gemma 4 E2B https://localrigcheck.com/gemma-4/ BF16 , Gemma 4 E4B https://localrigcheck.com/gemma-4/ BF16 , Qwen3.8-27B https://localrigcheck.com/qwen-3-8-27b/ UD-Q4 K XL fit with every layer in GPU memory. These are RigCheck capacity estimates for llama.cpp at a 32K context in the finder's quick mode, not measured setups; larger models need system RAM or a Mac, and image and video models are judged by planning budgets and published recipes.

Match your GPU, Mac or Spark to NVIDIA's own Nemotron 3.5 Bolt and Super VL recipes and Unsloth's memory budgets, with the launch command. Image and video Judged by planning budgets and published recipes, not by a measured peak. - FLUX 3 Image Klein https://localrigcheck.com/flux-3-image-klein/ : GeForce RTX 3060 12 GB + 32 GB RAM: Matches BFL's 8 GB guidance: the int8 files in ComfyUI published route match . BFL: the int8 ComfyUI files run on 8 GB GPUs such as the RTX 3070. Image model, int8 text encoder and VAE together are 11.0 GB; by our reading, on a card smaller than that ComfyUI keeps them on the GPU one at a time and needs system RAM for the rest. BFL gives no RAM figure. The prompt upsampler BFL says not to skip is a 9B model 6.72 GB w4a8, 9.75 GB int8 or 18.8 GB BF16 in ComfyUI ; BFL does not say whether its 8 GB figure includes it. When it does not fit with the image model, run it on its own first BFL's README or switch it off in the ComfyUI template, with weaker results. - MiniMax H3 https://localrigcheck.com/minimax-h3/ : GeForce RTX 3060 12 GB + 32 GB RAM: Hardware memory matches a published video recipe; exact clip peak unverified published recipe match . Matching recipes: SGLang Recipe A lab : one card, DiT, text encoder and VAE streamed from the checkpoint file on an NVMe drive Recipe A , BF16; measured at 864×480 at the native 768P the cookbook says to use video vae=24 if the decode runs out of memory, not measured ; lab run with VRAM capped at 12 GiB and a simulated 32 GB host: shows the memory fits, not your card's speed; a real 32 GB machine re-reads the weights from disk on every step. H3-Base FL2VA, source recipe canvases only. Disk-streaming routes assume an NVMe drive. Host-RAM and lab assumptions remain in the full checker; full 2K needs an API. - Qwen-Image-2.1 https://localrigcheck.com/qwen-image-2-1/ : GeForce RTX 3060 12 GB + 32 GB RAM: Above the all-components-resident planning budget; offload peak unverified planning budget . Uncalibrated allowances, not a minimum or a guarantee. Full checkpoint files are counted in host RAM even when mmap or sequential loading can use less. Actual peak depends on attention, prefix caches, VAE tiling, reference sizes and backend. No speed prediction.

RigCheck is independent and not affiliated with any model developer. Found a wrong number? Email hello@localrigcheck.com mailto:hello@localrigcheck.com with the source. How RigCheck works https://localrigcheck.com/about/ . FAQ How do I know if my GPU can run a model? Pick your card and RAM in the finder above, or open your graphics card's page https://localrigcheck.com/gpus/ . Each answer comes from that model's own checker, and says which kind it is: the llama.cpp checkers add up the file, the context cache and buffers against your memory; the Strata checker applies Strata's published requirements; Kolibri-1's matches official minimum configurations and a community recipe; image models use a planning budget and video models match published recipes. The full checker on each model page https://localrigcheck.com/models/ takes your exact setup. What does "with caveats" mean? The model fits only with part of it in system RAM slower , or the memory peak is not measured, or the route is one the checker marks as conditional. The checker says which; RigCheck never shows a caveat as a plain yes. Can a Mac run these models? Many of them: on a Mac the graphics and the processor share one pool of unified memory, so the finder judges a Mac by its total memory. Open the page for your Mac's memory size https://localrigcheck.com/macs/ or pick your Mac in the finder; the Strata engine https://localrigcheck.com/strata/ runs on Apple Silicon only experimentally. Are these numbers measured? Mostly not. The llama.cpp checkers' memory answers are RigCheck capacity estimates from the published file sizes; Strata's follow its published requirements, Kolibri-1's match official minimum configurations or a community recipe, and image and video answers are planning budgets or published recipes. Speeds are labeled as an official measurement, an official estimate or a community report; a measurement names the card and setup it was run on. How RigCheck works https://localrigcheck.com/about/ . Which models does RigCheck cover? Newly released open-weights models and a few popular mid-size ones, each with its own checker. The model list https://localrigcheck.com/models/ shows them all with their sizes, weights status, runtimes and license.
