OpenRouter
Pros
- + Migrated an existing assistant project in under an hour — base URL and model string were the only real changes
- + No-markup token pricing is stated and held on the model pairs I spot-checked; the fee is a single published number
- + BYOK: first $25,000/month of list-price inference fee-free on Standard and Business plans
- + Public pricing API (no key) and per-model llms.txt pages make cost modelling unusually easy
- + Model fallback turned an unreachable preferred provider into a completed request in my failure test
Cons
- - 5.5% credit fee (card, $0.80 minimum) is a permanent tax versus paying providers directly
- - Same-model output differed subtly between fallback providers — validators must be output-agnostic
- - Free plan's 50 requests/day ceiling kills prototypes; caching and routing are paywalled behind Standard
- - No SLAs outside Enterprise; your uptime is the upstream provider's uptime
- - 500+ model count includes many near-duplicates and deprecated versions — curation is on you
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
