Llama 4 Scout VRAM needed and GPU rental cost
Llama 4 Scout has 108.6 billion parameters (from the model card). Weights alone take 217.2 GB at FP16. With a 20% allowance for the KV cache and activations, plan for about 261 GB of VRAM at FP16, 130 GB at FP8 and 65 GB at INT4. The cheapest public on-demand way to hold it at FP8 is 2x A100 at Thunder Compute, $2.18/hr.

FAQ
Llama 4 Scout questions
How much VRAM does Llama 4 Scout need?
About 261 GB at FP16, 130 GB at FP8 and 65 GB at INT4. These are estimates: parameters times bytes per parameter, plus 20% for the KV cache and activations. Long contexts and large batches need more.
Can Llama 4 Scout run on one H100?
An H100 has 80 GB. At FP16 it needs 4 H100 GPUs, at FP8 2 and at INT4 1, by this estimate.
What does it cost to rent a GPU for Llama 4 Scout?
At FP8 the cheapest public on-demand option we track is 2x A100 at Thunder Compute, $2.18/hr, about $1,591.40 for a 730-hour month. At INT4 it is 1x A100 at Thunder Compute, $1.09/hr. Prices change often, so check the source link on each row. Last checked Nov 9, 2026.
How are these estimates made?
Memory is the parameter count times bytes per parameter (2 for FP16, 1 for FP8, 0.5 for INT4), times 1.2. Fine-tuning uses 2 bytes for LoRA, 0.5 for QLoRA and 16 for full fine-tuning with Adam (2 weights, 2 gradients, 12 optimizer bytes), times 1.2. Real usage depends on the framework, context length and batch size.
