Updated July 12, 2026
The best LLM for writing isn't the one topping general leaderboards - writing quality and reasoning quality often diverge. We ranked 15 models by a human-preference creative-writing benchmark, then added judgment on price, access, and where each one actually earns its slot. ## Best LLMs for Writing

## [Claude Fable 5](https://www.anthropic.com/news/claude-fable-5-mythos-5) Anthropic
Top-tier creative prose
Visit Anthropic
The strongest pure prose model in the current benchmark, and it shows most on fiction, voice, and nuance, though you pay a real premium for it.
Score 100% Price {"$40.00 / 1M"} License Proprietary Context 1M
  • It sits at the top of our writing benchmark for a reason: it holds a consistent voice across long pieces, handles subtext and rhythm, and rarely flattens into generic AI cadence.
  • If you want the highest ceiling for fiction, essays, or brand voice, this is the pick.
  • It's the most expensive model here by a wide margin, and creative-writing strength doesn't guarantee factual accuracy or clean SEO structure.
  • For research-heavy or high-volume drafting, Gemini 3.1 Pro or Claude Sonnet 5 give you most of the quality for far less.
## [Claude Opus 4.6](https://www.anthropic.com/news/claude-opus-4-6) Anthropic
High-end prose value
Visit Anthropic
A previous-generation Opus that still writes near the very top of this list for meaningfully less than Fable 5.
Score 98% Price {"$20.00 / 1M"} License Proprietary Context 1M
  • It nearly matches Fable 5 on prose quality for far less, which makes it our value pick for serious writing. It's strong at long-form structure, argument, and holding tone, and it writes better than the newer Opus 4.8.
  • Reach for it when you want near-frontier output without the top price.
  • Being a prior release, it may be retired or repriced before newer Claudes, so check availability if you're building on it.
  • Fable 5 still has a higher ceiling for the hardest creative work, and Opus 4.8 is the stronger all-round reasoning model.
## [Gemini 3.1 Pro](https://ai.google.dev/gemini-api/docs/models/gemini-3.1-pro-preview) Google
Long-form research writing
Visit Google
Google's strongest current writing model, best when your draft leans on long source documents and research rather than pure style.
Score 79% Price {"$9.50 / 1M"} License Proprietary Context 1M
  • The best pick here for research-heavy and long-form work, with a huge context that lets you draft from many sources at once. It stays organized across long outputs and handles structured, factual writing better than most of the higher-scoring creative models.
  • A strong default for reports and documentation.
  • It's a notch below the top Claude models on voice and creative nuance, so it's not our first choice for fiction or distinctive brand writing.
  • It's also a preview release on Google's routes, so pricing and availability can shift - confirm both before you commit.
## [Gemini 3.5 Flash](https://ai.google.dev/gemini-api/docs/models/gemini-3.5-flash) Google
High-volume drafting and editing
Visit Google
A fast, cheaper Gemini that punches above its tier for writing, ideal when you're generating or editing at volume.
Score 72% Price {"$7.13 / 1M"} License Proprietary Context 1M
  • Unusually strong prose for a fast, low-cost model, with the same large context as the Pro tier.
  • It's built for speed and throughput, making it the pick when you're drafting, rewriting, or editing in bulk and want quality that holds up without slowing you down.
  • It doesn't have the top prose ceiling, so for your most important creative or high-stakes pieces, Fable 5, Opus 4.6, or Gemini 3.1 Pro do better.
  • Use Flash where volume, cost, and speed matter more than peak polish.
## [Claude Opus 4.8](https://www.anthropic.com/news/claude-opus-4-8) Anthropic
Current flagship Claude default
Visit Anthropic
The newest flagship Opus and a superb all-round model, though for pure creative writing the older Opus 4.6 actually scores higher.
Score 64% Price {"$20.00 / 1M"} License Proprietary Context 1M
  • The most capable current Claude for reasoning, instruction-following, and mixed work that blends writing with analysis or code.
  • When your writing sits inside broader tasks - briefs, technical docs, judgment-heavy editing - it's a dependable default that keeps quality high across the whole job.
  • For pure creative prose it's a real step down from Opus 4.6, an unusual case where the older Opus is the better writer at the same price.
  • If style and voice are your priority, choose Opus 4.6 or Fable 5 instead.
## [Muse Spark](https://ai.meta.com/blog/introducing-muse-spark-msl/) Meta
Writing inside Meta AI
Visit Meta
Meta's surprise strong writer, but you can only use it inside the Meta AI app - there's no API and no pricing to compare.
Score 64% Price {"n/a"} License Proprietary Context n/a
  • Genuinely strong prose that scores with the mid-pack frontier models, wrapped in a free, mainstream consumer app.
  • If you write casually and just want good output without setting up API access or paying per token, it's an easy and capable option.
  • There's no public API or published pricing, so you can't build on it or budget for it, and there's no local route.
  • For any programmatic or team workflow, a model with real API access - the Claude, Gemini, or GPT options - is the practical choice.
## [Grok 4.20](https://docs.x.ai/developers/models) xAI
Distinctive voice and style
Visit xAI
The Grok to use for writing with edge and personality, and notably it beats the newer Grok 4.3 on prose.
Score 60% Price {"$2.19 / 1M"} License Proprietary Context 1M
  • It writes with more attitude and less hedging than most models here, which makes it fun for opinionated, casual, or voice-driven content.
  • It's also cheap for its quality, so it's a sensible pick when you want personality and volume without a big bill.
  • That distinctive voice can tip into glib or off-tone for formal and professional writing, where a Claude or Gemini model is safer.
  • Worth knowing that the newer Grok 4.3 writes worse here, so don't assume the higher version number is the better writer.
  • App — Available in Grok.
  • API — Accessible via xAI API.
## [GPT-5.5](https://openai.com/index/gpt-5-5-instant) OpenAI
Reliable general-purpose writing
Visit OpenAI
OpenAI's best writer in our set and a dependable generalist, though it trails the top Claude and Gemini models on prose.
Score 54% Price {"$23.75 / 1M"} License Proprietary Context 1M
  • A well-rounded, familiar writing model that handles most everyday tasks - drafts, emails, summaries, rewrites - with steady quality and strong instruction-following.
  • If you want one broadly capable model for mixed writing work, it's an easy and low-risk default.
  • It sits mid-pack for creative prose, so for fiction, voice, or your highest-stakes pieces the top Claude and Gemini models clearly do better.
  • Note that our score is for the Instant variant, so higher-effort GPT-5.5 modes may read differently.
## [Qwen3.7 Max](https://qwen.ai/blog?id=qwen3.7) Alibaba
Long-context multilingual writing
Visit Alibaba
Alibaba's flagship writer, most interesting for long-context and multilingual drafting rather than top-tier English prose.
Score 44% Price {"$3.13 / 1M"} License Proprietary Context 1M
  • A capable flagship with a large context window and solid multilingual range, useful if you write across languages or from long documents.
  • It's reasonably priced for a proprietary frontier model, which makes it a practical choice when breadth matters more than peak English prose.
  • For English creative writing it sits mid-pack, well behind the Claude and Gemini leaders.
  • It's also a preview release with regional access and API caveats, so confirm availability in your region before you rely on it.
## [GLM-5.2](https://docs.z.ai/guides/llm/glm-5.2) Z.ai
Current open-weight writing
Visit Z.ai
The current GLM and a solid open-weight writer, though the older GLM-5.1 actually scores higher for prose.
Score 44% Price {"$3.65 / 1M"} License Open weight Context 1M
  • A strong open-weight option with a large context and weights you can route through whichever host fits your cost or compliance needs.
  • Good all-round writing quality for the price, and it's the most current, best-supported model in the GLM line.
  • The older GLM-5.1 writes better on this benchmark, so pick 5.2 for freshness and support, not for top score.
  • Despite open weights, it needs real self-hosting infrastructure rather than a laptop, so most people will use a hosted API anyway.
  • App — Available in Z.ai.
  • API — Accessible via Z.ai API.
  • Run locally — Open weights are available from Hugging Face, but in practice this needs self-hosting infrastructure, not a local machine.
## [DeepSeek V4 Pro](https://huggingface.co/deepseek-ai/DeepSeek-V4-Pro) DeepSeek
Low-cost open-weight writing
View on Hugging Face
The value standout here: open weights and near-GLM writing quality at one of the lowest prices on the list.
Score 42% Price {"$0.76 / 1M"} License Open weight Context 1M
  • Remarkably cheap for its quality, with open weights and a large context.
  • It writes at roughly the level of pricier open-weight rivals while costing a fraction, which makes it our best value pick when you're generating writing at scale and watching cost.
  • It's mid-pack on prose, so it's a value play, not a quality leader - the top Claude and Gemini models write clearly better.
  • Open weights need self-hosting infrastructure rather than a laptop, and the score reflects its slower thinking mode.
  • App — Available in DeepSeek Chat.
  • API — Accessible via DeepSeek API.
  • Run locally — Open weights are available from Hugging Face, but in practice this needs self-hosting infrastructure, not a local machine.
## [MiMo-V2.5-Pro](https://mimo.xiaomi.com/mimo-v2-5-pro/) Xiaomi
Cheap open-weight drafting
Visit Xiaomi
A low-cost open-weight option worth knowing if you want cheap, capable drafting from outside the usual US and Chinese labs.
Score 35% Price {"$0.76 / 1M"} License Open weight Context 1M
  • Very cheap, with open weights and a large context, and it holds its own against other budget open-weight models for everyday writing.
  • A reasonable pick if you're routing high-volume, low-stakes drafting and want to keep costs near the floor.
  • It's toward the lower end of this list for quality, so it's a budget workhorse, not a model for polished or high-stakes writing. There's no first-party app, and local use means self-hosting, not a laptop.
  • For a little more money, DeepSeek V4 Pro writes better.
  • API — Accessible via OpenRouter.
  • Run locally — Open weights are available from Hugging Face, but in practice this needs self-hosting infrastructure, not a local machine.
## [Claude Sonnet 5](https://www.anthropic.com/news/claude-sonnet-5) Anthropic
Everyday Claude writing value
Visit Anthropic
The sensible everyday Claude for writing - clearly cheaper than Fable or Opus, and good enough for most drafting and editing.
Score 32% Price {"$8.00 / 1M"} License Proprietary Context 1M
  • A fast, affordable Claude that handles the bulk of routine writing well - drafts, edits, summaries, and clean structure - with the reliability and tone control Claude is known for.
  • It's the right default when Fable 5 and the Opus models are more than the task needs.
  • It scores below the older Opus rows and the Gemini leaders, so for your most demanding creative or long-form work, step up to Opus 4.6 or Fable 5.
  • Think of it as the workhorse, not the showpiece.
## [Kimi K2.6](https://platform.kimi.ai/docs/guide/kimi-k2-6-quickstart) Moonshot
Open-weight prose and critique
Visit Moonshot AI
A capable open-weight writer with a loyal following, good for drafting and sharp critique if you don't need frontier prose.
Score 31% Price {"$3.24 / 1M"} License Open weight Context 262K
  • A well-liked open-weight model that writes cleanly and is especially handy for editing and critiquing existing text.
  • Open weights give you routing and privacy flexibility, and it's a practical, mid-priced option for teams that want an open model for everyday writing.
  • Its context window is the smallest here alongside Gemma, which limits very long documents, and it sits low on prose quality. Despite open weights, it's too large for a personal machine, so you're on a hosted API.
  • For cheaper open-weight value, DeepSeek V4 Pro wins.
  • App — Available in Kimi.
  • API — Accessible via Kimi API.
  • Run locally — Open weights are available from Hugging Face, but in practice this needs self-hosting infrastructure, not a local machine.
## [Gemma 4 31B](https://huggingface.co/google/gemma-4-31B-it) Google
Laptop-friendly local writing
View on Hugging Face
The one model here you can genuinely run on a normal computer, trading top quality for offline, private, zero-cost writing.
Score 20% Price {"$0.34 / 1M"} License Open weight Context 262K
  • The most local-friendly pick by far: it runs on a typical machine, so you get offline use, privacy, and no per-token cost.
  • Great for private drafting, learning, and low-stakes writing where you want full control and nothing leaving your device.
  • It has the lowest prose score here, so expect noticeably weaker writing than any hosted frontier model - fine for notes and casual drafts, not polished work.
  • If you can use the cloud at all, almost everything above it writes better.
*** ## How to Choose When choosing between these models, consider: * **Access:** Decide first whether you'll use a model in an app, call it through an API, or self-host, because that choice drives cost, privacy, latency, and setup. Most models here are app-and-API; only Gemma 4 31B runs comfortably on a normal machine, and Muse Spark is app-only. * **Quality:** Our score normalizes the Arena Text Creative Writing Elo, a human-preference ranking of creative prose. It captures voice and style well, but it doesn't measure factual accuracy, SEO structure, or editing reliability - so treat it as a prose signal, not a verdict on every kind of writing. * **Price:** We use blended cost per million tokens at a 1:3 input-to-output ratio so you can compare on one number. Open-weight models can be cheaper still if you self-host, but only Gemma runs locally without server-grade hardware. * **Context window:** A bigger window matters when you draft from long sources or many documents at once. Most models here reach about 1M tokens; Kimi K2.6 and Gemma 4 31B are the notable smaller exceptions at 262K. *** ## Other Models We Considered
*** ## Frequently Asked Questions For pure prose quality, Claude Fable 5 is the top of our list. But Claude Opus 4.6 writes almost as well for half the price, so it's the one most serious writers should reach for first. Claude Sonnet 5 and Gemini 3.5 Flash. Both are strong, affordable, and easy to access in a mainstream app, and they cover the everyday drafting and editing most people actually do. Muse Spark, if you're happy working inside the Meta AI app. If you'd rather run something yourself for free, Gemma 4 31B is the only pick here that runs on a normal computer at no per-token cost. GLM-5.2 is the strongest current open-weight writer with active support. DeepSeek V4 Pro is the value choice, and Gemma 4 31B is the one you can actually run locally. Gemma 4 31B. It's the only model on this list that runs comfortably on a typical machine. The other open-weight models - GLM-5.2, DeepSeek V4 Pro, MiMo-V2.5-Pro, Kimi K2.6 - technically have downloadable weights but need server-grade hardware. Because writing quality and version number don't move together. Opus 4.6 was tuned in a way that produces better creative prose than Opus 4.8, even though 4.8 is the newer, stronger all-round model. For writing specifically, 4.6 wins. Partly. Our score comes from human preference on creative prose, so it tracks voice and style well. It says little about factual accuracy, SEO structure, or reliable editing, so a high score is a good starting signal, not a guarantee for your exact task. Only for the hardest creative work - fiction, distinctive brand voice, or pieces where prose quality is the whole point. For most writing, Opus 4.6 gets you nearly the same result for far less.
