Pros

• ✓One subscription spans the widest agentic surface at the Plus price point: ChatGPT Agent automates web tasks, Deep Research returns cited reports, Codex writes and ships code, and Tasks run between sessions, all within the $20 per month Plus tier.
• ✓The GPT-5.6 family handles multimodal analysis, long-context reasoning, and image generation without separate subscriptions or API keys, giving more model breadth per dollar than any comparable AI subscription.
• ✓Custom GPTs and the API let teams deploy domain-specific agents with no ML infrastructure, from a CRM assistant to a data analyst, and share them across a workspace or publicly.

Limitations

• ⚠Autonomous features are rate-limited on Plus: agent mode struggles with complex multi-step flows involving authentication or dynamic pages, and Pro at $100 per month is the practical minimum for meaningful autonomous volume.
• ⚠Data training is opt-out rather than off by default on Free, Go, and Plus, so protecting sensitive conversations requires an active settings change, unlike the no-training default on Business and Enterprise.
• ⚠General-purpose breadth means less depth than vertical specialists: Harvey AI (custom pricing) leads on legal research, Gong (custom pricing) on call analysis, and Intercom Fin ($0.99 per resolution) on support resolution.

Pros

• ✓Real-time web access with inline citations on every claim. Deep Research generates PowerPoints, spreadsheets, and dashboards from a research prompt, and Computer autonomously executes multi-step tasks across the web and Office apps.
• ✓Multiple frontier models under one subscription. Pro includes Gemini 3.1 Pro, Sonar 2, and Claude Sonnet 4.6. Max adds the most advanced reasoning models with unlimited research scale, a meaningful TCO advantage versus separate subscriptions.
• ✓Comet browser is free on all platforms and embeds AI research, summarization, and in-page task automation on every webpage. Personal Computer for Mac extends autonomous task execution to local files and applications at no additional cost.

Limitations

• ⚠Comet collects browsing and search history to build ad-targeting profiles with no in-app opt-out currently offered. Enterprise Pro and Max customers receive a guaranteed no-training commitment, but Comet ad-profiling is a separate data use.
• ⚠Reasoning quality on non-research tasks lags behind Claude and ChatGPT Pro. Perplexity excels at search-augmented work but is not the right tool for complex multi-step reasoning, code generation, or creative writing.
• ⚠The price gap between Pro ($17/month) and Max ($167/month) is dramatic. Max is nearly 10x the Pro price with no intermediate option, and Enterprise Max at $271/seat competes with broader enterprise platforms at similar cost.
