Limitations
–The Free tier is tightly restricted to 3 Pro Searches per day and just 1 Deep Research query per month with no manual model selection.
–Power users requiring heavy agentic Computer runs or uncapped o3-pro/Opus-level research must jump from $20/month Pro to the steep $200/month Max tier.
–Synthesized summaries can still inherit inaccuracies if underlying top-ranked web sources contain outdated or biased reporting.
