FAQ of Claude.ai
Free handles daily chats (15-20 messages/session); upgrade to Pro ($20) only if hitting caps on long reasoning/coding. Casual users test free forever—Pros’ 5x boost suits pros without overkill, Max ($100).
Pro unlocks Claude Code/500K context (vs GPT’s 128K), better reasoning per benchmarks. Developers fearing “hallucinations” start Pro trial-equivalent (no card)—annual saves $36, ROI via 2x productivity.
Pro (~45 messages/week heavy use) fits professionals; Max $100 (5x) for automation/heavy loads. Power users calculate using Anthropic’s estimator—start Pro, upgrade seamlessly as you scale.
Custom Team offers SSO/shared projects at a lower cost than OpenAI Enterprise. SMBs demo free access first—Pro ($20/user) baselines solo before team scaling, with API for apps.
Per-token pricing (e.g., Sonnet $3/1M input); Pro includes web priority. Budget devs use Free for prototyping, Pro/API combo for prod—docs detail estimators vs OpenAI’s opacity.
Pro’s vision excels in math/charts (95% accuracy tests)—marketers/analysts start at $20 for Docs integration. Free tests basics; upgrade if daily image workflows demand Opus precision.
Pro access Sonnet 4.5 immediately + projects for context. Switchers trial free (import chats), confirm superior reasoning/coding before $20—cancellations easy, no lock-in.
Custom Enterprise negotiates SSO/limits for teams. Growing orgs start Pro per user, migrate seamlessly—ROI from 50% efficiency gains per case studies justifies vs consultants.
