I don’t really use Twitter so I’ve never used it via the bot, I’ve only ever used it via the web app.
I bounced back and forth between Grok and Perplexity for web search type tasks and at least for the moment am preferring Grok mostly because it seems to perform more searches and check more results per query vs Perplexity and their $10/mo plan covers my usage vs $20 for Perplexity Pro.
However I’m not married to any LLM service and will switch to another one the moment I get better results from it.
At least in my usage I haven’t noticed any obvious bias, but I don’t really search for politically related stuff so maybe I just haven’t seen it.
Its plausibly not in the API and only on the twitter bot, but I see no reason to trust x.ai given this history of obvious manipulation.
