For most content teams, Claude Sonnet 5 is the best value for article writing in 2026, at $0.0203 for a 1,500-word draft — high enough quality to edit rather than rewrite, without flagship pricing. If volume matters more than polish, GPT-5 mini drops that to $0.00400. Prices are list rates verified 2026-09-24.
Choose a model by the cost of a useful editorial draft—not token
price alone. We weigh API cost against quality fit, latency and the human review each
workflow still needs.
It is our best overall value for teams that want a polished first draft without
paying flagship-model prices. Use a smaller model when volume matters more; move up
to Opus only when the article is complex enough to justify it.

Three questions that decide the model. Every branch lands within five cents an
article of every other, so the editing each implies matters more than the rate.
Five practical picks
Choose by workflow
Costs use one 1,500-word draft, a 250-word brief and 20% prompt overhead.
Best overall
Claude Sonnet 5
The strongest balance of draft quality and mid-tier API cost for a normal editorial workflow.
Token cost is the smallest line in the budget. Here is what happens when you add the
only line that is actually large.
At an editorial rate of $50 an hour, the API
is 0.01% of what an article costs. Everything else is the time
someone spends making the draft publishable — which means the model that minimises that time
wins, even when its tokens cost ten times more.

The editing times are illustrative, not measured. They
are the assumption the table exists to expose — plug in your own team's figures and the
ranking may change. What does not change is the shape: editing minutes dominate token cents
at every realistic rate.
What the table says
Claude Opus 5 at $12.55 beats Gemini 2.5 Flash at $37.50
The model with the highest token cost finishes cheapest per finished article,
because it is assumed to need thirty fewer minutes of work. Across 100 articles a month that
is a difference of $2,495 — money that never appears on an API
invoice and therefore never gets attributed to the model choice that caused it.
Being straight about this
How we assess quality fit — and what that rating is not
Every comparison page on the internet rates models. Most do not say where the rating
came from. Here is ours.
“Quality fit” is an editorial judgement, not a
benchmark score. We have not run a controlled evaluation, and we are not going to imply
that we have. What the rating reflects is described below, so you can weigh it accordingly — or
discount it entirely and use the price data, which is verified.
What it is based on
Published model characteristics
Each
provider's own positioning of a model within its lineup — which tier it sits in, what it is
documented as being for, and how it is priced relative to its siblings.
What it is based on
Hands-on use for this workload
Drafting
long-form prose from a brief specifically. A model that is excellent at code or extraction
may not be the same model at 1,500 words of continuous argument.
What it is not
Not a factuality measure
No rating here says a
model is more accurate. Every model produces confident wrong sentences, and verifying them is
human work at every price point.
What it is not
Not a reproducible score
There is no test
suite behind it and no number you could re-derive. If you need that, run your own
evaluation on your own briefs — it is the only assessment that reflects your house style.
What is verified
The prices, and only the prices
Every figure on this page is computed from rates transcribed by hand from the
five providers' own pricing pages and re-checked weekly. The judgements about quality and latency
are opinion. We keep them clearly separated so you can take one without the other, and
the methodology shows exactly how the priced half is derived.
The other direction
When the cheap model is the wrong answer
Most advice on this topic points one way. These are the cases where it should not.
01
Nobody is editing
If the draft publishes largely as
generated, the model is doing quality control it was not priced to do. Buy the better draft
— it is still fractions of a cent.
02
The topic is technical
Structural errors in a technical
argument take longer to find and fix than surface errors in a general one. Repair time rises
faster than the price gap.
03
Low volume
At four articles a month the entire spread
between cheapest and dearest is a rounding error. Optimising it is time you could spend on
the brief, which affects output far more.
04
The brief is thin
Cheaper models lean harder on a good
brief. If the input is vague, the cheap draft degrades faster and the saving disappears into
rewriting.
The rule of thumb: economy tiers are for workflows that already
have an editor in the loop. They are a way to spend the budget on editing instead of tokens —
not a way to skip the editing.
05
The volume is high enough to own the hardware
Every pick above is a per-token rental, so the bill rises with every article forever. Past
a few thousand drafts a month that arithmetic starts losing to a machine you already have and
an open-weight model running on it, where the marginal draft costs electricity. The catch is
that the constraint stops being price and becomes VRAM — whether the weights and the KV cache
fit on the card at your context length. RunMyLLM
profiles that per GPU; price the API side here first, because the crossover is much further
out than most people expect.
Beyond the five picks
How the providers differ
The picks above are five models out of 55. Each provider prices differently,
and the differences decide more than the headline rates do.
Anthropic
9 models · from $0.0101
Output averages 5.0Ă— input.
Eligible Batch token charges are 50% off.
Cheapest full draft: Claude Haiku 4.5.
Output averages 2.4Ă— input.
Grok 4.3 and Grok 4.20 Batch is 20% off; other tracked Grok models do not support Batch.
Cheapest full draft: Grok Build 0.1.
The questions people actually ask before committing to one.
Is Claude or GPT better for writing articles?
Neither wins outright; they win at different points on the price curve. OpenAI has the widest range, including both the cheapest tracked model and the most expensive. Anthropic has the most consistent structure — output is exactly five times input on every model — which makes budgeting predictable. For a draft an editor will lightly touch, a mid-tier Claude model is the common choice; for high-volume work an OpenAI mini model usually costs less.
What is the cheapest AI model that still writes usable articles?
The economy tiers — GPT-5 nano, Gemini Flash-Lite — produce text cheaply but need real editing, so they suit workflows with an editor already in the loop. If nobody is editing, a mid-tier model costs a fraction of a cent more per article and arrives far closer to publishable. The cheapest model is only cheapest when you ignore what happens after generation.
Does the expensive model actually write better?
Usually it produces a draft that needs less structural repair, particularly on complex or technical pieces. It does not make the draft factually reliable — every model can produce confident, wrong sentences, and verifying those is human work regardless of model tier.
Should I use the batch tier for article generation?
Consider Batch when your publishing schedule can wait for asynchronous results. Eligible Claude, OpenAI and Gemini charges are 50% off; Grok 4.3 and Grok 4.20 are 20% off. Other tracked Grok models do not support Batch. Compare supported model-specific rates, turnaround and retry requirements.
How much does prompt caching help for content workflows?
Less than people expect. Caching discounts input only, and an article workflow is overwhelmingly output — a 1,500-word draft is around 1,950 output tokens against a few hundred of input. Caching pays off when a large fixed system prompt or style guide is reused across many requests, not because you generate many articles.
Can I use a cheap model for client work?
That is an editorial policy question rather than a pricing one. The relevant test is whether your review process catches what the model gets wrong. If a cheap draft goes through the same verification a human draft would, the model tier matters less; if it is published largely as generated, the tier is doing quality control it was not priced to do.
How many drafts should I budget for?
One generated draft plus human editing is the most common working pattern. Multiple iterative drafts cost more than a simple multiple, because with iterative revision each redraft re-sends the previous draft as input — the calculator models this, and the methodology page shows the arithmetic.
Do these recommendations change when prices change?
The figures do, automatically — every number on this page is computed from the same price data the calculator uses, so a re-verification updates the prose. The editorial judgements about quality fit and latency are reviewed separately and are not recomputed.
The bottom line
Optimize for an accepted draft, not the cheapest generation
API generation is only one line in the budget. Research, source verification,
editing, subject-matter review, images and publishing remain separate costs. So does being
found: a draft only earns back its cost if search engines and AI assistants are allowed to
read it, and a robots.txt
that admits Googlebot, GPTBot and ClaudeBot costs nothing but is easy to get wrong.
