Recommendation
For moderate usage, a US$ 20/month subscription like ChatGPT Plus or Claude Pro is often the best value. APIs usually make sense later.
How we calculate the estimates
These estimates use official API pricing available in March 2026.
For text and coding use cases, we estimate average tokens per interaction based on common workloads.
For image generation, we use estimated cost per image. For video, we estimate a 15-second clip.
Subscriptions have a fixed monthly price, but they still include message or usage limits.
All values are in USD and should be treated as directional planning numbers.
