Pros and cons

ChatGPT

Pros

  • One assistant covers text, voice, images, file analysis, search and coding
  • Free tier lets users try the service without a card
  • Apps for web, iOS, Android, macOS and Windows with synced history
  • Large ecosystem of connectors, projects and agent features
  • Plans range from $8 to $500 per month, so users can match spend to usage

Cons

  • Free and Go usage limits are low and may include ads
  • Pricing and model lineup change often, which makes limits hard to compare over time
  • Answers can be wrong and need checking, especially for facts and citations
  • The top Pro tiers cost $100 to $500 per month

OpenRouter

Pros

  • Single OpenAI-compatible endpoint covering 500+ models from 80+ providers, so switching models rarely needs code changes.
  • Inference passes through at provider list prices with no markup and no minimums or lock-in.
  • Automatic provider fallbacks reduce exposure to outages and rate limits.
  • Free models and a free router allow testing without paying.
  • Enterprise options include SSO/SAML, SLAs, EU and US in-region routing and private endpoints.

Cons

  • A 5.5% (Standard) or 8% (Business) platform fee applies to every credit purchase, and platform fees are non-refundable.
  • The free tier has no auto-routing, budgets, prompt caching or BYOK, and is limited to 50 requests per day.
  • No official mobile app or desktop client; mobile access is through third-party clients.
  • Business and Enterprise pricing, and the Stripe acquisition announced in August 2026, add some uncertainty about future terms.
