DeepSeek V4-Flash vs Llama 4 Scout

DeepSeek · China  |  Meta · US · Updated June 2026

Quick verdict

Pick DeepSeek V4-Flash for exceptional value — artificial analysis intelligence index 52 at just $0.14/$0.28 per million tokens or mit-licensed open weights — free to self-host or run via a western host. Pick Llama 4 Scout for largest advertised context (10m) or open weights, single-gpu friendly. On a tight budget at scale, Llama 4 Scout is the value pick.

DeepSeek V4-Flash (DeepSeek, China) and Llama 4 Scout (Meta, US) line up two different AI ecosystems against each other — a comparison that is as much about cost philosophy and openness as raw capability. DeepSeek V4-Flash is deepSeek's MIT-licensed open-weight model — arguably the best value-per-intelligence available, scoring 52 on the independent AA Index at just $0.14/$0.28 per million tokens. Llama 4 Scout is the 10M-token open-weight giant — enormous on paper, but usable recall is far smaller. They diverge most on price and context window — each quantified below from the models' real specs.

Who wins what

Exceptional value — Artificial Analysis Intelligence Index 52 at just $0.14/$0.28 per million tokens

DeepSeek V4-Flash

DeepSeek's MIT-licensed open-weight model — arguably the best value-per-intelligence available, scoring 52 on the independent AA Index at just $0.14/$0.28 per million tokens — and it is the newer of the two.

MIT-licensed open weights — free to self-host or run via a Western host

DeepSeek V4-Flash

DeepSeek V4-Flash lists mIT-licensed open weights — free to self-host or run via a Western host among its strengths; Llama 4 Scout does not.

1M-token context window

DeepSeek V4-Flash

Llama 4 Scout is comparatively weak here — ~15% on long-context multi-needle reasoning

Largest advertised context (10M)

Llama 4 Scout

Its 10M window holds about 10× more than DeepSeek V4-Flash's 1M in a single prompt.

Open weights, single-GPU friendly

Llama 4 Scout

The 10M-token open-weight giant — enormous on paper, but usable recall is far smaller — and it carries the larger 10M context.

Self-hosted, data-private deployment

Llama 4 Scout

DeepSeek V4-Flash is comparatively weak here — deepSeek's own hosted API stores data in China; self-host or use a Western host for privacy

Lowest cost at scale

Llama 4 Scout

Its weights are open, so at volume you pay for your own hardware instead of DeepSeek V4-Flash's $0.14/$0.28 per 1M tokens.

Largest single-prompt input

Llama 4 Scout

Its 10M window is about 10× larger than DeepSeek V4-Flash's 1M, fitting roughly 15,000 pages in one prompt.

Which should you pick?

A cost-sensitive startup shipping high volume

Llama 4 Scout

At Open weight (self-host / free) it undercuts DeepSeek V4-Flash, and on millions of tokens that margin decides the monthly bill.

Someone analysing very long documents or codebases

Llama 4 Scout

Larger 10M window fits more in one prompt.

Anyone whose priority is exceptional value — artificial analysis intelligence index 52 at just $0.14/$0.28 per million tokens

DeepSeek V4-Flash

It is specifically built for that.

Anyone whose priority is largest advertised context (10m)

Llama 4 Scout

That is its strongest area.

An enterprise with regional data-residency rules

Llama 4 Scout or DeepSeek V4-Flash

Origin (China vs US) affects where data is processed and which compliance regime applies — check the provider's terms for your region.

DeepSeek V4-Flash: where it fits

DeepSeek's MIT-licensed open-weight model — arguably the best value-per-intelligence available, scoring 52 on the independent AA Index at just $0.14/$0.28 per million tokens. Released July 31, 2026 by DeepSeek, it is built for exceptional value — Artificial Analysis Intelligence Index 52 at just $0.14/$0.28 per million tokens, mIT-licensed open weights — free to self-host or run via a Western host, 1M-token context window, and strong coding and agentic performance for the price (DeepSeek reports 82.7 on Terminal-Bench 2.1).

Its trade-offs are real: coding/agentic figures like Terminal-Bench 82.7 are DeepSeek's own, not independently reproduced, text and code focused — not a full multimodal model, deepSeek's own hosted API stores data in China; self-host or use a Western host for privacy, and below the top frontier models on overall intelligence. At $0.14 in / $0.28 out per million tokens, it sits in the budget price band.

Llama 4 Scout: where it fits

The 10M-token open-weight giant — enormous on paper, but usable recall is far smaller. Released April 2025 by Meta, it is built for largest advertised context (10M), open weights, single-GPU friendly, self-hosted, data-private deployment, and retrieval over very long inputs.

Its trade-offs: effective recall degrades far below 10M, and ~15% on long-context multi-needle reasoning. As an open-weight model, its running cost is your own hardware rather than a per-token fee.

The bottom line for this matchup

This is less "which is smarter" and more "which ecosystem fits." DeepSeek V4-Flash (China) and Llama 4 Scout (US) differ on pricing philosophy, data-residency, and tooling as much as on raw scores. Llama 4 Scout is the cheaper option, which matters at volume. The pragmatic move is to run one real task through both and judge the outputs against your own constraints — including where your data is allowed to be processed.

Frequently asked questions

Is DeepSeek V4-Flash or Llama 4 Scout better for coding?

Public SWE-Bench figures are not available for either model, so the honest test is your own repository — run an identical real bug through both. By design, DeepSeek V4-Flash leans toward exceptional value — artificial analysis intelligence index 52 at just $0.14/$0.28 per million tokens while Llama 4 Scout leans toward largest advertised context (10m), and that positioning usually predicts which feels better on your codebase.

Which is cheaper, DeepSeek V4-Flash or Llama 4 Scout?

Llama 4 Scout is cheaper — $0.14/$0.28 per 1M tokens vs Open weight (self-host / free).

Which has the bigger context window?

Llama 4 Scout — 10M vs 1M, about 10× larger. Useful only if the model actually reasons over the full window, which not all do.

Can I use both DeepSeek V4-Flash and Llama 4 Scout together?

Yes — a multi-model platform like LumiChats gives you DeepSeek V4-Flash, Llama 4 Scout and 40+ others under one ₹69/day pass (about $1/day), so you can draft with one and cross-check with the other instead of buying two subscriptions.

Which is newer, DeepSeek V4-Flash or Llama 4 Scout?

DeepSeek V4-Flash — released July 31, 2026, about 16 months after Llama 4 Scout.
