xAI Grok
Pros
- + Live web plus timestamped X citations gave me source coverage on a breaking story that conventional search engines had not indexed yet
- + Cached input at $0.50/1M on grok-4.7 cut my repeated-prompt agent loop cost by roughly 70% versus uncached billing in my runs
- + The $30 Premium tier bundles SuperGrok, Cursor Pro and X Premium+ that xAI says previously cost $90 combined
- + Multi-agent mode exposes each sub-agent's reasoning chain, so the merged answer is auditable rather than a black box
- + One API covers text, images, video and voice: stills from $0.02/image and video from $0.02/second on the lightest tiers
Cons
- - Billed cost doubles past 200k input tokens on grok-4.7 ($2.00 to $4.00/1M input), a cliff I tripped with a 240k-token upload
- - X-sourced citations included two unsourced low-follower claims that Grok folded into its summary without flagging
- - Loose content policy and X corporate ownership make it a poor default for regulated or customer-facing brand work
- - Plan packaging changed on 12 October 2026 (The X Subscription), so pricing guides written before then, and some SuperGrok pages, disagree
- - No provisioned throughput or reserved capacity option; only the $100 Super tier advertises priority access at peak times
ChatGPT
Pros
- + Broadest multimodal surface in the category: text, reasoning, images, voice, video and agents in one subscription
- + Plus at $20/month is still the value anchor — my mixed weekly workload ran without visible caps
- + Deep research produced a 12-source competitive scan in about 8 minutes (two citation fixes needed, structure worth keeping)
- + GPT/connector ecosystem covers odd-shaped needs that no competitor matches
- + Business seat-type mixing (Standard + one Premium) is a sensible team pricing pattern
Cons
- - Free, Go, Plus and Pro conversations train models unless you opt out; no SOC 2 or SSO below Business
- - Caps downgrade silently to weaker models — quality drops without a warning
- - Ads now run on Free and Go in the US, including on a paid tier (Go)
- - Pro ladder ($100/$200/$500) buys capacity, not capability, with no annual discount anywhere in the lineup
- - Editing temperament drifts to confident verbosity; citations overreached sources in my deep research run
