Atria-Dawn VRAM Requirements

Shanghai AI Lab, China · Released October 23, 2026New

Atria-Dawn has 753.3B parameters (40B active per token). In BF16 its weights alone take 1385 GiB; quantized to 4-bit, about 418 GiB. Each 32K-token request adds 2.83 GiB of KV cache. Cheapest way to run it today: 5 × RTX PRO 6000 Blackwell (96 GB) at $6.34 per hour.

How many GPUs to run Atria-Dawn

Fewest GPUs that fit the weights plus one 8K-token request. Data-center GPUs use vLLM (90% of memory usable), the others llama.cpp. Several GPUs split the model with tensor or pipeline parallelism.

8-bit: FP8 with vLLM (INT8 on GPUs without FP8), Q8_0 with llama.cpp. 4-bit: AWQ / GPTQ with vLLM, Q4_K_M with llama.cpp, both counted at the Q4_K_M size.

Cheapest way to run Atria-Dawn today

For each GPU: the fewest cards that fit Atria-Dawn with one 8K-token request, the most faithful weight format at that count, and the cheapest on-demand price (2026-10-23).

On-demand prices from AWS, Google Cloud, Azure, RunPod, Vast.ai, Oracle Cloud, OVHcloud, Scaleway, Verda, Akash and UpCloud, checked every hour. Serving many users needs more KV cache, so more memory: size it in the calculator. Some links are affiliate links: StudioTV may earn a commission, at no extra cost to you.

KV cache: how memory grows with context

Architecture: 78 layers · MLA (512 + 64 latent) on 78 · indexer keys on 21. Its cache stays compact because MLA stores one compressed latent per token and layer instead of full keys and values. Only 40B parameters are active per token, but all 753B must sit in memory: VRAM depends on the total, speed on the active part.

Atria-Dawn VRAM FAQ

How much VRAM does Atria-Dawn need?

In BF16 the weights alone take 1385 GiB (1487 GB). In FP8 that is 694 GiB, and about 418 GiB with 4-bit quantization (Q4_K_M). Each request then adds KV cache: 0.71 GiB at 8K tokens and 2.83 GiB at 32K (BF16 cache).

Can Atria-Dawn run on a single RTX 4090 (24 GB)?

No. Even in 4-bit it needs 24 RTX 4090s, spread over several machines. In 4-bit it needs 7 H100 GPUs.

Can Atria-Dawn run on an RTX 5090 (32 GB)?

No. Even in 4-bit it needs 16 RTX 5090s, spread over several machines.

Can Atria-Dawn run on a Mac?

No single Mac holds it, even in 4-bit: it needs 419 GiB with an 8K-token context, and the largest Mac (512 GB) gives its GPU about 384 GB.

Can Atria-Dawn run on a DGX Spark or a Ryzen AI Max+ 395 (128 GB)?

No. Even in 4-bit it needs 4 DGX Spark units or 5 Ryzen AI Max+ 395 machines (128 GB), linked over the network.

What is the cheapest way to run Atria-Dawn?

On 2026-10-23, the cheapest on-demand setup is 5 × RTX PRO 6000 Blackwell (96 GB) with Q4_K_M weights on Vast.ai, at $6.34 per hour (about $4,628.20 per month). Next: 3 × AMD MI300X (192 GB) with 4-bit weights on RunPod, at $7.17 per hour. Sized for one 8K-token request; prices are checked every hour.

How many H100 GPUs does Atria-Dawn need?

With one request and an 8K-token context: 24 in BF16, 16 in FP8 and 7 in 4-bit (vLLM, 90% of memory usable). Above 8 GPUs, that means several servers. Serving many users at once needs more memory for their KV caches: the calculator sizes that for you.
