# Claude Sonnet 4.6 for social media

> The previous Sonnet: fast and highly capable, tagged for both long-form and short copy. Useful for keeping a voice consistent with posts you already wrote on it.

Claude Sonnet 4.6 is one of 80+ AI models in Autoadify, the AI agent for social media. No Anthropic 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:** Anthropic
- **What it is:** Fast and highly capable
- **Best for:** Long-form, Short copy
- **Available on:** every plan, including Free
- **Cost band:** High, relative to its own type

## What to make with Claude Sonnet 4.6

- **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.
- **Captions that stop the scroll** (Instagram, TikTok, Facebook): Instagram and TikTok captions where the first line has to earn the tap on "more".

**Pick it when:** You want continuity with copy written on Sonnet 4.6.

**Try Claude Sonnet 5 instead** for the current Sonnet 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".

| X / Twitter | 280 characters | No preview cut — the whole post shows. |
| Instagram | 2,200 characters | About 125 show before the cut (truncated in feed). |
