Pricing Tier
Consumer products bundle as Free/Pro/Max/Enterprise; APIs bill pay-as-you-go per token.
- Two billing models: subscription vs per-token.
- Subscriptions cheaper for daily chat; APIs cheaper for automation past a threshold.
- Per-feature pricing (cache, batch, vision) varies.
When to use: When choosing between consumer chat and API for a given workflow.
Example: ChatGPT Plus and Claude Pro are $20/mo with caps; Claude API Sonnet is $3/M input tokens.
