LFM3-1.7B vs Llama 4 Scout

Liquid AI · US  |  Meta · US · Updated June 2026

Quick verdict

Pick LFM3-1.7B for very small open-weight text model - about 1.73b parameters with a 256k-token context for on-device use or liquid says it can power agentic applications that used to need 9b parameters. Pick Llama 4 Scout for largest advertised context (10m) or open weights, single-gpu friendly.

LFM3-1.7B (Liquid AI) and Llama 4 Scout (Meta) are two of the models people most often weigh against each other in 2026. LFM3-1.7B is liquid AI's October 27, 2026 on-device text model - about 1.73B parameters and 256K context, with open weights under a license capped at $10M annual revenue. Llama 4 Scout is the 10M-token open-weight giant — enormous on paper, but usable recall is far smaller. Their biggest split is context window, and the breakdown below shows exactly how that plays out for your workload.

Who wins what

Very small open-weight text model - about 1.73B parameters with a 256K-token context for on-device use

LFM3-1.7B

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

Liquid says it can power agentic applications that used to need 9B parameters

LFM3-1.7B

Liquid AI's October 27, 2026 on-device text model - about 1.73B parameters and 256K context, with open weights under a license capped at $10M annual revenue — and it is the newer of the two.

Part of a six-model LFM3 family covering text, vision, audio, omni and decision tasks

LFM3-1.7B

LFM3-1.7B lists part of a six-model LFM3 family covering text, vision, audio, omni and decision tasks among its strengths; Llama 4 Scout does not.

Largest advertised context (10M)

Llama 4 Scout

Its 10M window holds about 39× more than LFM3-1.7B's 256K tokens 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

Llama 4 Scout lists self-hosted, data-private deployment among its strengths; LFM3-1.7B does not.

Largest single-prompt input

Llama 4 Scout

Its 10M window is about 39× larger than LFM3-1.7B's 256K tokens, fitting roughly 15,000 pages in one prompt.

Which should you pick?

Someone analysing very long documents or codebases

→ Llama 4 Scout

Larger 10M window fits more in one prompt.

Anyone whose priority is very small open-weight text model - about 1.73b parameters with a 256k-token context for on-device use

→ LFM3-1.7B

It is specifically built for that.

Anyone whose priority is largest advertised context (10m)

→ Llama 4 Scout

That is its strongest area.

LFM3-1.7B: where it fits

Liquid AI's October 27, 2026 on-device text model - about 1.73B parameters and 256K context, with open weights under a license capped at $10M annual revenue. Released October 27, 2026 by Liquid AI, it is built for very small open-weight text model - about 1.73B parameters with a 256K-token context for on-device use, liquid says it can power agentic applications that used to need 9B parameters, part of a six-model LFM3 family covering text, vision, audio, omni and decision tasks, and supports 16 languages.

Its trade-offs are real: lFM Open License v1.0 covers commercial use only below $10M annual revenue; larger firms need a paid license, liquid says it is not recommended for agentic coding or complex multi-step reasoning because of its size, text-only; vision and audio need other LFM3 checkpoints, and no published per-token API price found. As an open-weight model, its running cost is your own hardware rather than a per-token fee.

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

LFM3-1.7B and Llama 4 Scout overlap enough that the right pick depends on your specific job. Llama 4 Scout holds the larger context; and each leads in its own area — LFM3-1.7B for very small open-weight text model - about 1.73b parameters with a 256k-token context for on-device use, Llama 4 Scout for largest advertised context (10m). Rather than crowning one, run the same hard task through both once and let the results decide.

Frequently asked questions

Is LFM3-1.7B 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, LFM3-1.7B leans toward very small open-weight text model - about 1.73b parameters with a 256k-token context for on-device use while Llama 4 Scout leans toward largest advertised context (10m), and that positioning usually predicts which feels better on your codebase.

Which is cheaper, LFM3-1.7B or Llama 4 Scout?

They are priced almost identically, so cost will not decide between them.

Which has the bigger context window?

Llama 4 Scout — 10M vs 256K tokens, about 39× larger. Useful only if the model actually reasons over the full window, which not all do.

Can I use both LFM3-1.7B and Llama 4 Scout together?

Yes — a multi-model platform like LumiChats gives you LFM3-1.7B, 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, LFM3-1.7B or Llama 4 Scout?

LFM3-1.7B — released October 27, 2026, about 19 months after Llama 4 Scout.
