Why each one is on the shortlist for moonshot model for writing, what it is genuinely good at, and where we would steer you away from it.
Ranked first here for moonshot model for writing: 38/100 on budget, with the widest margin of anything in this line-up.
Moonshot's 2.8-trillion-parameter multimodal reasoning flagship with always-on thinking — the largest open-weight model ever released and the closest Chinese challenger to the Western frontier.
You need fast responses or predictable output costs — always-on thinking burns tokens.
The first Chinese model to genuinely crowd the Western frontier — #4 on aggregate intelligence ahead of Opus 4.8. The always-on thinking makes it slow and output-heavy, so cost per task runs above the sticker price. A serious Opus-class alternative if latency isn't critical.

The cost-conscious pick for moonshot model for writing, about 73% less per token than Kimi K3 than the top choice while holding 85/100 on budget.
An open-weight 1T-parameter MoE (32B active) coding specialist tuned for long-horizon agentic software engineering with markedly better token efficiency than its predecessor.
Your agent needs big-repo context (256K cap) or frontier general reasoning.
The value pick among coding specialists. K3 superseded it at the frontier a month later, but for pure coding-agent volume at a quarter of K3's input price, K2.7 Code remains the smarter buy.

Kimi K3 — it scores 90/100 on writing in this directory, ahead of Kimi K2.7 Code at 68/100. Closest Chinese challenger to the frontier — #4 overall on intelligence.
Not overall. Claude Fable 5.1 (Anthropic) leads the directory for writing at 98/100 vs Kimi K3's 90/100. Kimi K3 is the best pick if you're staying within Moonshot's ecosystem.
Kimi K2.7 Code at $0.95/1M input tokens (writing score: 68/100). Use it for volume work and reserve Kimi K3 for the tasks where quality matters most.
$3/1M input tokens and $15/1M output tokens via the API, or through Kimi Moderato at $19/mo for chat use. Context window: 1M tokens. On a moderate month — 10M input and 2M output tokens — that works out to about $60.00, against $17.50 for Kimi K2.7 Code.
Most expensive Chinese-lab model ever ($3/$15) with always-on thinking driving high output-token burn and slow responses. 2.8T size makes self-hosting impractical despite open weights; consumer signups were paused July 19 over GPU capacity. Concretely, avoid it if you need fast responses or predictable output costs — always-on thinking burns tokens. If none of that is negotiable, Claude Fable 5.1 (Anthropic) is the cross-provider leader at 98/100.
hardest reasoning tasks — #4 of all models on AA Intelligence Index v4.1 (57.1), ahead of Claude Opus 4.8, agentic coding at 81.2 FrontierSWE and 88.3 Terminal-Bench 2.0 (Moonshot-reported), and 1M-context research synthesis with always-on extended thinking. Its 1M-token context window is the practical limit on how much you can hand it in one go.
Kimi K3 scores 90/100 on writing against 68/100 for Kimi K2.7 Code, at 3x 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.
