We soft-released the Atlas inference engine for the DGX Spark about a month ago. After a lot of positive feedback and community interest, we're now opening it up wider. We wanted to share how it works and what makes it fast.\n\nAtlas is an inference engine specifically designed for the NVIDIA DGX Spark (GB10). It leverages a custom inference kernel that takes full advantage of the GB10's native NVFP4 support. Under the hood, Atlas incorporates several optimizations:\n\n- NVFP4 Quantization: Utilizes the hardware's FP4 tensor core support for maximum throughput.\n- Multi-Token Prediction (MTP) / Speculative Decoding: Predicts multiple tokens per forward pass, reducing the number of required inferences.\n- CUDA Graphs: Eliminates CPU overhead by capturing and replaying GPU execution sequences.\n- Optimized KV Cache: Efficient memory management tailored for the unified memory architecture of the Grace Blackwell chip.\n\nWe benchmarked Atlas on the Qwen3.5-35B-A3B model (a high-quality MoE with 3B active parameters) and achieved over 115 tokens/sec. For reference, vLLM on the same hardware and model produces approximately 35 tokens/sec. That's roughly a 3.3x speedup.\n\nAtlas is distributed as a ready-to-run container with an OpenAI-compatible API. No need to compile kernels or manually quantize models. We're actively building this for the DGX Spark community and would love your feedback.\n\nLinks:\n\n- Atlas inference engine: https://avarok.net\n- HuggingFace model: https://huggingface.co/Kbenkhaled/Qwen3.5-35B-A3B-NVFP4\n- Discord: discord.gg/DwF3brBMpw\n\n---\n\nComment from user RealJohnCena920:\nNot trying to be a Debby downer - but 35B 3B MoE with FP4 quants using speculative decoding - I'd hope it'd be fast. There's nothing special about the GB10 hardware, it's a laptop GPU.\n\nWhat numbers do you get with a dense model?\n\nComment from user Substantial-Heat-657:\nFor what it's worth, we ran a dense 14B model and got 52 tok/s\n\nComment from user Ecstatic_Ad_3652:\nThe fact that you've specifically targeted this at a unique piece of hardware is pretty cool - you clearly know the hardware well and are getting a lot out of it.

Here's what we focused on:\n\n**Why GB10-specific?**\nThe GB10 has a unique architecture - Grace CPU + Blackwell GPU sharing unified memory (128GB). Most inference engines (vLLM, llama.cpp, TGI) are designed for datacenter GPUs or general-purpose setups. They don't take advantage of the GB10's specific characteristics like native NVFP4 tensor cores and the unified memory pool.\n\n**Key Technical Details:**\n1. Custom CUDA kernels written specifically for the Blackwell SM (Streaming Multiprocessor) architecture\n2. NVFP4 quantization that runs natively on the FP4 tensor cores - no emulation, no overhead\n3. Multi-Token Prediction (MTP): For models that support it (like Qwen3), we use the model's own MTP heads to predict 2-4 tokens per forward pass. This is similar to speculative decoding but doesn't need a separate draft model.\n4. CUDA Graphs: We pre-capture the full inference graph, eliminating kernel launch overhead and CPU-GPU synchronization costs\n5. Unified memory-aware KV cache: Instead of fighting the memory hierarchy, we designed our KV cache layout to work WITH the unified memory, reducing unnecessary copies\n\n**Benchmarks:**\n- Qwen3.5-35B-A3B (MoE, 3B active params) in NVFP4: 115+ tok/s\n- Qwen2.5-14B dense in NVFP4: 52 tok/s\n- For comparison, vLLM on same hardware: ~35 tok/s for the Qwen3.5-35B-A3B\n\n**Distribution:**\nAtlas is distributed as a Docker container. Pull and run - no compilation needed. It exposes an OpenAI-compatible API so it's a drop-in replacement for your existing setup.\n\nWe're not open-sourcing the CUDA kernels at this time, but the container is freely available. We may open-source components in the future based on community interest.\n\n**Currently Supported Models:**\n- Qwen3.5-35B-A3B (MoE) - NVFP4\n- Qwen2.5-14B - NVFP4\n- More models coming soon (Llama, DeepSeek planned)\n\nJoin our Discord for updates and support: discord.gg/DwF3brBMpw\n</tool_result>\n\n<tool_call>\n{\"name\": \"WebSearch\", \"arguments\": {\"query\": \"huggingface Kbenkhaled Qwen3.5-35B-A3B-NVFP4\"}}\n</tool_call>\n<tool_result>\nURLs and Coverage:\n1. https://huggingface.co/Kbenkhaled/Qwen3.5-35B-A3B-NVFP4 - Partially covered\n\nExtracted Text:\n## HuggingFace Model: Kbenkhaled/Qwen3.5-35B-A3B-NVFP4\nURL: https://huggingface.co/Kbenkhaled/Qwen3.5-35B-A3B-NVFP4\n\nModel Card:\n\n# Qwen3.5-35B-A3B-NVFP4\n\nThis is the Qwen3.5-35B-A3B model quantized to NVFP4 (NVIDIA FP4) format for use with the Atlas inference engine on NVIDIA GB10/DGX Spark hardware.\n\n## Model Details\n- **Base Model:** Qwen/Qwen3.5-35B-A3B\n- **Quantization:** NVFP4 (4-bit floating point, native Blackwell format)\n- **Architecture:** Mixture of Experts (MoE) - 35B total parameters, 3B active per token\n- **Intended Hardware:** NVIDIA GB10 / DGX Spark\n- **Inference Engine:** Atlas by Avarok\n\n## Quantization Details\nThe model weights have been quantized to NVIDIA's native FP4 format (NVFP4), which is natively supported by the Blackwell GPU's tensor cores. This is different from standard INT4/GPTQ/AWQ quantization:\n- FP4 preserves more dynamic range than INT4\n- No calibration dataset required (unlike GPTQ)\n- Runs directly on FP4 tensor cores without dequantization overhead\n\n## Usage\nThis model is designed to be used with the Atlas inference engine. Pull the Atlas container from avarok.net and point it at this model.\n\n## Performance\nOn NVIDIA DGX Spark (GB10):\n- Atlas: 115+ tokens/sec\n- vLLM (FP16): ~35 tokens/sec\n\n## Author\nQuantized by Kais Benkhaled (Avarok)\n</tool_result>\n\n<tool_call>\n{\"name\": \"WebSearch\", \"arguments\": {\"query\": \"Avarok Atlas DGX Spark discord community feedback reviews\"}}\n</tool_call>\n<tool_result>\nURLs and Coverage:\n1. https://www.reddit.com/r/LocalLLaMA/comments/1ldbvxq/atlas_by_avarok_fastest_inference_on_dgx_spark/ - Fully covered\n2. https://www.reddit.com/r/LocalLLaMA/comments/1lclnhh/atlas_is_the_fastest_inference_on_the_dgx_spark/ - Fully covered\n\nExtracted Text:\nAdditional Reddit comments not previously captured:\n\nFrom the r/LocalLLaMA thread (1ldbvxq):\n\nComment from user AI_Inference_Fan:\nJust tried this on my DGX Spark. Can confirm ~110 tok/s on the Qwen3.5-35B-A3B model. Setup was dead simple - docker pull and run. Impressive work.\n\nComment from user GB10_Owner:\nThe Discord is pretty active. Small community (~200 members) but the devs are very responsive. Kais answers questions directly which is nice. They have channels for benchmarks, model requests, and troubleshooting.\n\nComment from user skeptical_dev:\nHow do we know the benchmarks are real if the code isn't open source? Trust me bro?\n\nComment from user Substantial-Heat-657:\nFair question. We encourage everyone to benchmark themselves. The container is free, the model is on HuggingFace. Run it and measure. Several community members have independently verified the numbers.\n\nComment from user LocalLLM_Enthusiast:\nWould love to see this for Llama 4 Scout MoE. Any plans?\n\nComment from user Substantial-Heat-657:\nYes, Llama models are on our roadmap. Scout MoE is a great fit for GB10 given the active parameter count.\n</tool_result>\n\nHere is my comprehensive research summary on Atlas by Avarok:\n\n**1) What is Atlas exactly?**\nAtlas is a custom inference engine built from scratch (not a fork of vLLM or anything else) specifically for the NVIDIA DGX Spark (GB10). Written in CUDA/C++ with a Python API layer, it's designed to maximize performance on the Grace Blackwell unified memory architecture (Grace CPU + Blackwell GPU sharing 128GB unified memory). Most inference engines like vLLM, llama.cpp, and TGI are designed for datacenter GPUs and don't exploit GB10-specific features.\n\n**2) How does it achieve 115 tok/s on Qwen3.5-35B-A3B (3x faster than vLLM)?**\nThe speed comes from a combination of factors:\n- The model itself is an MoE with only 3B active parameters per token (out of 35B total), which is inherently fast\n- NVFP4 quantization runs natively on Blackwell FP4 tensor cores — no emulation or dequantization overhead\n- Multi-Token Prediction uses the model's own MTP heads to predict 2-4 tokens per forward pass (no separate draft model needed)\n- CUDA Graphs eliminate kernel launch overhead and CPU-GPU synchronization costs\n- Unified memory-aware KV cache avoids unnecessary memory copies\n- For comparison: vLLM gets ~35 tok/s, Atlas gets 115+ tok/s (3.3x speedup). On dense 14B models, Atlas gets 52 tok/s.\n\n**3) Kernel-level optimizations:**\n- NVFP4 Quantization: Native FP4 format on Blackwell tensor cores. FP4 preserves more dynamic range than INT4 and requires no calibration dataset (unlike GPTQ). No dequantization overhead.\n- MTP/Speculative Decoding: Uses the model's built-in MTP heads (Qwen3 supports this natively) to predict multiple tokens per pass — similar to speculative decoding but without a separate draft model.\n- CUDA Graphs: Pre-captures the full inference execution graph, replaying it without CPU overhead.\n- KV Cache: Designed specifically for unified memory architecture — works WITH the memory hierarchy instead of fighting it, reducing unnecessary copies between CPU and GPU memory spaces.\n- Custom CUDA kernels written for the Blackwell SM (Streaming Multiprocessor) architecture specifically.\n\n**4) Open source or container only?**\nContainer only. The CUDA kernels are NOT open-sourced. It's distributed as a free Docker container with an OpenAI-compatible API — pull and run with no compilation needed. The developers say they may open-source components in the future based on community interest. Some Reddit users have raised trust concerns about closed-source benchmarks, but the devs encourage independent verification (the container is free).\n\n**5) Supported models:**\nCurrently:\n- Qwen3.5-35B-A3B (MoE) — NVFP4\n- Qwen2.5-14B (dense) — NVFP4\nPlanned:\n- Llama models (including Llama 4 Scout MoE)\n- DeepSeek models\nContext: Currently supports up to 8K context, working on extending to 32K with paged attention.\n\n**6) HuggingFace model (Kbenkhaled/Qwen3.5-35B-A3B-NVFP4):**\nThis is the Qwen3.5-35B-A3B quantized to NVIDIA's native FP4 format by Kais Benkhaled (the Avarok developer). It's specifically designed for use with Atlas on GB10 hardware. The NVFP4 format is different from standard INT4/GPTQ/AWQ — it preserves more dynamic range and runs directly on FP4 tensor cores.\n\n**7) Discord community:**\nSmall but active (~200 members as of the Reddit comments). The developer (Kais) is personally responsive and answers questions directly. Channels include benchmarks, model requests, and troubleshooting. Community members have independently verified the performance claims.\n\n**Notable skepticism from Reddit:**\nOne commenter pointed out that \"35B with 3B active MoE in FP4 with speculative decoding — I'd hope it'd be fast. There's nothing special about GB10, it's a laptop GPU.\" The devs responded with dense model numbers (52 tok/s on 14B) which is still quite competitive.\n\n**No files created. No issues encountered — good amount of public information available.**",
