Laguna M.1 VRAM Requirements

poolside, United States · Released June 15, 2026

Laguna M.1 has 225.8B parameters (23B active per token). In BF16 its weights alone take 421 GiB; quantized to 4-bit, about 127 GiB. Each 32K-token request adds 8.75 GiB of KV cache. Cheapest way to run it today: 6 × GeForce RTX 3090 (24 GB) at $0.648 per hour. It calls tools and has a thinking mode you can switch off.

How many GPUs to run Laguna M.1

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 Laguna M.1 today

For each GPU: the fewest cards that fit Laguna M.1 with one 8K-token request, the most faithful weight format at that count, and the cheapest on-demand price (2026-11-06).

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.

Recommended settings for Laguna M.1

Sampling defaults from the official generation_config.json (opens in a new tab) of poolside/Laguna-M.1.

vLLM and SGLang apply these defaults unless a request sets its own. With llama.cpp, pass them yourself: --temp 1 --top-p 1 --min-p 0

Reasoning. Thinking mode you can switch on or off. With vLLM or SGLang, set it per request: "chat_template_kwargs": {"enable_thinking": false} turns it off, true on. Reasoning tokens take context and KV cache like any other token: leave room for them.

KV cache: how memory grows with context

Architecture: 70 layers · 70 full attention (8 KV × 128). Every layer keeps keys and values for every token (grouped-query attention), so the cache grows linearly with context. Only 23B parameters are active per token, but all 226B must sit in memory: VRAM depends on the total, speed on the active part.

Laguna M.1 VRAM FAQ

How much VRAM does Laguna M.1 need?

In BF16 the weights alone take 421 GiB (452 GB). In FP8 that is 211 GiB, and about 127 GiB with 4-bit quantization (Q4_K_M). Each request then adds KV cache: 2.19 GiB at 8K tokens and 8.75 GiB at 32K (BF16 cache).

Can Laguna M.1 run on a single RTX 4090 (24 GB)?

No. Even in 4-bit it needs 6 RTX 4090s. In 4-bit it fits on a single NVIDIA B200 (HGX) (180 GB).

Can Laguna M.1 run on an RTX 5090 (32 GB)?

No. Even in 4-bit it needs 5 RTX 5090s.

Can Laguna M.1 run on a Mac?

Yes. In 4-bit (Q4_K_M with llama.cpp) it needs a Mac with 192 GB of unified memory or more, of which macOS gives the GPU about 144 GB, for one request with an 8K-token context. In 8-bit (Q8_0) it needs 512 GB.

Can Laguna M.1 run on a DGX Spark or a Ryzen AI Max+ 395 (128 GB)?

No. Even in 4-bit it needs 2 DGX Spark units or 2 Ryzen AI Max+ 395 machines (128 GB), linked over the network.

What is the cheapest way to run Laguna M.1?

On 2026-11-06, the cheapest on-demand setup is 6 × GeForce RTX 3090 (24 GB) with Q4_K_M weights on Vast.ai, at $0.648 per hour (about $473.04 per month). Next: 3 × RTX A6000 (48 GB) with Q4_K_M weights on Vast.ai, at $0.966 per hour. Sized for one 8K-token request; prices are checked every hour.

How many H100 GPUs does Laguna M.1 need?

With one request and an 8K-token context: 7 in BF16, 4 in FP8 and 2 in 4-bit (vLLM, 90% of memory usable). Serving many users at once needs more memory for their KV caches: the calculator sizes that for you.

Does Laguna M.1 support tool calling?

Yes, Laguna M.1 supports tool (function) calling: it can ask your application to run a function and use the result.

Does Laguna M.1 have a thinking mode?

Thinking mode you can switch on or off. With vLLM or SGLang, set it per request with "chat_template_kwargs": {"enable_thinking": false} (or true). Reasoning tokens count toward the context and the KV cache.

What temperature should I use with Laguna M.1?

The official defaults are temperature 1, top-p 1, min-p 0.
