# Kimi K3 for social media

> Moonshot AI's model with a 1M-token context, tagged for long-form. Useful when a long post or thread has to draw on a lot of source material at once.

Kimi K3 is one of 80+ AI models in Autoadify, the AI agent for social media. No Moonshot AI account or API key is needed: every model is in one subscription, chosen per generation — by asking the AI agent, in a social media AI workflow step, or in AI Studio.

- **Lab:** Moonshot AI
- **What it is:** Moonshot AI — 1M context
- **Best for:** Long-form
- **Available on:** every plan, including Free
- **Cost band:** High, relative to its own type

## What to make with Kimi K3

- **LinkedIn posts with an argument** (LinkedIn): Posts of several hundred words that hold a point from the first line to the last.
- **Threads** (X, Threads, Bluesky): A multi-post thread where each post stands alone and the whole still reads as one piece.

**Pick it when:** You are turning a long document — a report, a transcript — into LinkedIn posts or a thread.

**Try Claude Sonnet 5 instead** for everyday long-form at a lower cost band.

## Character limits it writes to

Autoadify writes each platform's version to that platform's limit. The number that matters most is often the preview: the part shown before "more".

| Platform | Spec | Note |
| --- | --- | --- |
| X / Twitter | 280 characters | No preview cut — the whole post shows. |
| Instagram | 2,200 characters | About 125 show before the cut (truncated in feed). |
| LinkedIn | 3,000 characters | About 210 show before the cut (truncated in feed). |
| TikTok | 2,200 characters | About 100 show before the cut (truncated in feed). |
| YouTube | 5,000 characters | About 157 show before the cut (truncated in search). |
| Facebook | 63,206 characters | About 480 show before the cut (truncated in feed). |
