GPT-5 nano vs Llama 4 Scout

Benchmarks, API pricing and specs, head to head. Data updated 2026-06-10.

GPT-5 nano

OpenAI · Aug 2025

OpenAI's cheapest model — $0.05 per million input tokens — for latency-critical routing, autocomplete and bulk tagging.

Llama 4 Scout

Meta · Apr 2025

A 10M-token context window — still the largest ever shipped — in a 109B MoE that fits on a single H100.

The verdict

These two models don't yet share verified results on the benchmarks we track, so judge them on specs, pricing and intended use. GPT-5 nano is about 2.1x cheaper per blended million tokens (3:1 input:output mix). Llama 4 Scout also takes 10M of context versus 400K for GPT-5 nano. And Llama 4 Scout is open-weights (Llama 4 Community License), so it can be self-hosted — a structural advantage if data control or vendor independence matters.
