Llama 4 Scout vs Palmyra X6

Meta · US  |  Writer · US · Updated June 2026

Quick verdict

Pick Llama 4 Scout for largest advertised context (10m) or open weights, single-gpu friendly. Pick Palmyra X6 for enterprise agentic workflows - built specifically for marketing/revenue teams running multi-step agents or writer says its harness upgrades cut agent-workflow token costs by roughly 52% and improve speed by roughly 48% (writer's own figures). Choose Llama 4 Scout if you need self-hosting or data privacy; Palmyra X6 if you want a managed API.

Llama 4 Scout (Meta) and Palmyra X6 (Writer) are two of the models people most often weigh against each other in 2026. Llama 4 Scout is the 10M-token open-weight giant — enormous on paper, but usable recall is far smaller. Palmyra X6 is writer's enterprise agentic flagship - a GLM-5.2-based model with harness upgrades Writer says cut agent token costs by roughly half. They diverge most on context window and open vs. closed weights — each quantified below from the models' real specs.

Who wins what

Largest advertised context (10M)

Llama 4 Scout

Its 10M window holds about 78× more than Palmyra X6's 128K in a single prompt.

Open weights, single-GPU friendly

Llama 4 Scout

Open weights make this possible at all — Palmyra X6 is API-only, so it cannot leave the vendor's servers.

Self-hosted, data-private deployment

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.

Enterprise agentic workflows - built specifically for marketing/revenue teams running multi-step agents

Palmyra X6

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

Writer says its harness upgrades cut agent-workflow token costs by roughly 52% and improve speed by roughly 48% (Writer's own figures)

Palmyra X6

Writer's enterprise agentic flagship - a GLM-5.2-based model with harness upgrades Writer says cut agent token costs by roughly half — and it is the newer of the two.

A post-trained variant built on Z.ai's open-weight GLM-5.2, tuned specifically for business agent use

Palmyra X6

Palmyra X6 lists a post-trained variant built on Z.ai's open-weight GLM-5.2, tuned specifically for business agent use among its strengths; Llama 4 Scout does not.

Largest single-prompt input

Llama 4 Scout

Its 10M window is about 78× larger than Palmyra X6's 128K, 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.

A team with data-privacy or self-hosting needs

Llama 4 Scout

Open weights let you run it on your own hardware; Palmyra X6 is API-only.

Anyone whose priority is largest advertised context (10m)

Llama 4 Scout

It is specifically built for that.

Anyone whose priority is enterprise agentic workflows - built specifically for marketing/revenue teams running multi-step agents

Palmyra X6

That is its strongest area.

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 are real: 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.

Palmyra X6: where it fits

Writer's enterprise agentic flagship - a GLM-5.2-based model with harness upgrades Writer says cut agent token costs by roughly half. Released August 13, 2026 by Writer, it is built for enterprise agentic workflows - built specifically for marketing/revenue teams running multi-step agents, writer says its harness upgrades cut agent-workflow token costs by roughly 52% and improve speed by roughly 48% (Writer's own figures), and a post-trained variant built on Z.ai's open-weight GLM-5.2, tuned specifically for business agent use.

Its trade-offs: no public per-token API price - sold through Writer's enterprise platform, not a self-serve API, not independently benchmarked on general leaderboards like SWE-bench or Artificial Analysis, and built for a narrower enterprise-agent use case rather than general-purpose chat.

The bottom line for this matchup

The defining split here is open vs. closed. Llama 4 Scout gives you weights you control — self-host it, fine-tune it, keep data in-house, pay only for hardware. Palmyra X6 gives you a managed, always-updated API with no infrastructure to run. Teams with GPUs, privacy requirements, or huge volume often favour the open model; teams that want zero ops and the latest capabilities favour the closed one. Capability is close enough that this operational question, not the benchmark, usually decides it.

Frequently asked questions

Is Llama 4 Scout or Palmyra X6 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, Llama 4 Scout leans toward largest advertised context (10m) while Palmyra X6 leans toward enterprise agentic workflows - built specifically for marketing/revenue teams running multi-step agents, and that positioning usually predicts which feels better on your codebase.

Which is cheaper, Llama 4 Scout or Palmyra X6?

Llama 4 Scout is open-weight, so self-hosting means no per-token fee (you pay for hardware instead), while Palmyra X6 is API-metered at Not published. For most teams without GPUs, the API model is cheaper to start; at very high volume, self-hosting can win.

Which has the bigger context window?

Llama 4 Scout — 10M vs 128K, about 78× larger. Useful only if the model actually reasons over the full window, which not all do.

Can I use both Llama 4 Scout and Palmyra X6 together?

Yes — a multi-model platform like LumiChats gives you Llama 4 Scout, Palmyra X6 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, Llama 4 Scout or Palmyra X6?

Palmyra X6 — released August 13, 2026, about 17 months after Llama 4 Scout.
