Grok
- +Strong real-time awareness from native web and X (Twitter) search
- +One product spans chat, voice, image and video generation, and a developer API
- +Frontier-class reasoning models with a multi-agent 'Heavy' tier for hard problems
- -The consumer app is an assistant, not an autonomous agent; agentic features live mostly in the developer API
- -Proprietary, single-vendor model with no model choice (unlike multi-model rivals)
Perplexity
- +Citation-grounded answers are verifiable, a real advantage over uncited chatbots
- +Model flexibility: not locked to one LLM, with a proprietary search-tuned Sonar family plus frontier models
- +Genuine breadth from quick answers to research, deliverables, and agentic browsing in one product
- -The agentic features are supervised, not autonomous, and hallucination risk persists despite citations
- -Tier proliferation with the best features gated behind paid or US-only access
