Muse Spark is Meta's best model for writing — it scores 88/100 vs 84/100 for Muse Spark 1.3, at $1.25/1M input tokens. Across all providers, Claude Sonnet 5.5 still leads writing at 98/100 — worth considering if you're not committed to Meta.
The safest meta model for writing default, the cheaper option worth trying first, and the specialist pick — before you read the detail below.
Muse Spark is the strongest answer here for meta model for writing — pick it when quality of output matters more than the $1.25/1M/1M input you pay for it.
Muse Glimmer 30B handles the same job for about 66% less per token. Start here and only move up if the output is not good enough.
Muse Spark 1.3 is the fastest of these for meta model for writing — worth it when latency is what the reader notices, not the last few points of reasoning depth.
Muse Spark leads Meta's lineup for writing at 88/100 ($1.25/1M input, 1.048576M context).
Muse Glimmer 30B is the value pick at $0.35/1M input with a writing score of 74/100.
Claude Sonnet 5.5 (Anthropic) is the overall writing leader at 98/100 if provider choice is open.
Choose Muse Spark when writing quality is the priority and you're staying on Meta.
Choose Muse Glimmer 30B when token volume matters more than peak quality.
Teams open to other providers should also evaluate Claude Sonnet 5.5 before committing.
Switch the scoring lens to see whether the meta model for writing answer changes when cost, speed, or long-document depth leads the decision.

Why each one is on the shortlist for meta model for writing, what it is genuinely good at, and where we would steer you away from it.
Our pick for meta model for writing. It scores 72/100 on the budget axis we weight this page by, and nothing else in this shortlist matches it on output quality.
Meta Superintelligence Labs' first closed frontier model — a natively multimodal agentic reasoner (text, image, video, audio, PDF in) with a parallel-agent 'Contemplating mode', priced aggressively below rivals.
You need frontier-ceiling reasoning or a mature developer ecosystem — Opus 5 and GPT-5.6 lead both.
Superseded: Muse Spark 1.3 (September 2, 2026) is the current version at the same price. Meta's surprise pivot to closed frontier models is a genuine value play: GPT-5.5-tier intelligence with the broadest multimodal input support, at prices that undercut OpenAI and Anthropic. The young API ecosystem is the main practical drawback.

Here for latency: it answers fastest of anything listed for meta model for writing, at 72/100 on budget.
Meta's September 2, 2026 update to Muse Spark — a multimodal reasoning model for long-horizon agent and coding work, with a 1M context and native understanding of video, images and documents.
You need published benchmark evidence before choosing a model.
A point release of Muse Spark at the same price. Use it in place of the original Muse Spark; we cannot rank it against Claude or GPT models until comparable benchmark figures are published.

Muse Spark — it scores 88/100 on writing in this directory, ahead of Muse Spark 1.3 at 84/100. Best-value multimodal agentic model — GPT-5.5-tier smarts, video/audio/PDF in.
Not overall. Claude Sonnet 5.5 (Anthropic) leads the directory for writing at 98/100 vs Muse Spark's 88/100. Muse Spark is the best pick if you're staying within Meta's ecosystem.
Muse Glimmer 30B at $0.35/1M input tokens (writing score: 74/100). Use it for volume work and reserve Muse Spark for the tasks where quality matters most.
$1.25/1M input tokens and $4.25/1M output tokens via the API, or through Meta AI (free) at $0/mo for chat use. Context window: 1.048576M tokens. On a moderate month — 10M input and 2M output tokens — that works out to about $21.00, against $6.50 for Muse Glimmer 30B.
Trails the frontier on raw intelligence: AA Intelligence Index 54 vs Claude Opus 5 (61) and GPT-5.6 Sol (59). Weak on some hard agentic evals (27% tau3-Banking) and the API ecosystem is young — public API only since July 2026. Concretely, avoid it if you need frontier-ceiling reasoning or a mature developer ecosystem — Opus 5 and GPT-5.6 lead both. If none of that is negotiable, Claude Sonnet 5.5 (Anthropic) is the cross-provider leader at 98/100.
agentic productivity work — powers Meta AI's email/calendar/slides agents since v1.1, terminal coding via the new Muse Code agent (v1.2 is coding-focused, 80% Terminal-Bench 2.1), and health and science reasoning — Contemplating mode hit 58% on Humanity's Last Exam. Its 1.048576M-token context window is the practical limit on how much you can hand it in one go.
Muse Spark scores 88/100 on writing against 74/100 for Muse Glimmer 30B, at 4x the input price. That premium is worth it on work where a wrong answer costs real time or money, and hard to justify on high-volume, low-stakes calls. Most teams run both and route by task rather than picking one.
