# DeepSeek V4 Flash for social media

> Fast DeepSeek with a 1.3M-token context. A budget model that can still read a lot before it writes — handy for summarising long material into short posts.

DeepSeek V4 Flash is one of 80+ AI models in Autoadify, the AI agent for social media. No DeepSeek 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:** DeepSeek
- **What it is:** Fast DeepSeek — 1.3M context
- **Best for:** Budget
- **Available on:** every plan, including Free
- **Cost band:** Low, relative to its own type

## What to make with DeepSeek V4 Flash

- **Daily posting on autopilot** (Instagram, Facebook, X): Run it in an AI Workflow every day without the cost adding up.
- **Variants to test** (Instagram, TikTok, X): Many versions of the same post, so the best one goes out.

**Pick it when:** Cheap, fast copy drawn from a lot of source text.

**Try DeepSeek V4 Pro instead** when the output itself is long-form.

## 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). |
