ChatGPT

by OpenAI

Perplexity AI

by Perplexity AI

Pros

• ✓One subscription covers chat, deep research, agent mode, ChatGPT Work and OpenAI Codex, across web, mobile and desktop apps.
• ✓Plans range from a free tier with unlimited GPT-5.6 Luna chats to Pro and Business Premium seats with the largest GPT-6 Astra allowances.
• ✓Business and Enterprise add SAML SSO, SCIM, data residency in ten regions and no training on workspace data, backed by SOC 2 Type 2 and ISO/IEC 42001.

Limitations

• –Content on Free, Go, Plus and Pro can be used for model training unless the user opts out in settings, and training is excluded by default only on Business and Enterprise.
• –Agent, Work and Codex usage draws on a monthly plan allowance, Free and Go have limited or no access to them, and Business and Enterprise buy credits beyond it.
• –New sign-ups and upgrades to the $200 Pro tier have been paused since September 10, 2026, and the $8 Go plan may include ads.

Pros

• ✓Perplexity both publishes MCP servers, one for its search and research tools and one that hands tasks to Computer, and consumes external MCP servers through its Agent API, so it can feed cited research into other AI tools and pull third-party tools into its own runs.
• ✓Paid plans let users choose between frontier models including GPT-6 Sol, Gemini 3.8 Flash, Claude Sonnet 5, Kimi K3, GLM 5.3 and Grok 4.6, and Effort Mode can pick the model and reasoning level for each Computer task.
• ✓Every answer carries inline citations, and Computer extends the same sourcing into Microsoft 365 documents and autonomous multi-step web tasks on all paid plans.

Limitations

• –Perplexity states that its original Sonar Chat Completions API is supported only until September 27, 2026, so developer integrations built on it need migrating to the Agent API.
• –Pro and Max are licensed for personal use only, so business buyers need Enterprise seats from $34 per seat per month billed annually, and SCIM, audit logs and data retention settings start at Enterprise Max or a custom-priced plan.
• –Consumer searches are used to improve Perplexity's models by default and the opt-out must be set manually in account settings, while the no-training commitment applies only to Enterprise plans.
