Best AI for social media
As of 2026-07-18, Anthropic: Claude Opus 4.8 (Fast) is the strongest model for this task in our daily benchmark, where over 350 AI models are evaluated and the best are presented.
Posts are short text, and short text exposes weak language ability immediately. There is nowhere to hide: one stiff sentence and the post smells of AI.
For social media we rank by language quality, because tone is the entire difference. Ranked by language score, from today’s benchmark.

Avoid the LinkedIn voice
Language models have read enormous amounts of marketing copy and fall back on it unless told otherwise. The result is posts that open with a rhetorical question and close with a call to action nobody asked for. Ask explicitly for the opposite: no emojis, no hashtags, no call to action, write like a person telling you something.
Use AI for variants, not finished text
The best workflow is to write the post yourself and ask for five alternative opening lines. That gives you the variation models are good at while keeping the voice that is yours.
