Subscribe or Tokens?

Flat AI subscription or pay-as-you-go API — which is cheaper for your usage?

Agentic coding tools read lots of files — input tokens dominate. A single Claude Code task can easily consume 100k–500k input tokens. Chat messages are far smaller (hundreds of tokens).

2 · Subscribe or tokens — per platform

Honesty box: API costs are exact math from published per-token rates. Subscription "value" is not — providers publish vague limits ("5x more usage") that change without notice. If your API-equivalent usage is many times a plan's price, you would likely hit that plan's cap. Treat subscription rows as "flat price, capped usage". Always verify prices at the source links below before deciding — they change frequently.

Chat subscriptions (ChatGPT Plus, Google AI plans) include image generation inside their general usage limits at no extra cost — if you already pay for one, try it before buying anything image-specific. Claude does not generate images. Midjourney bills GPU time, not images: capacity figures assume ~1 GPU-minute per image and are approximate; Standard and up add unlimited slower "relax" generation on top.

Why this exists

In July 2026, Hacker News front pages filled with the same complaint: AI pricing is confusing. Vague limits, models that leave subscriptions and move to usage credits, plans that quietly change mid-year. Most calculators compare API rates against each other — but the decision people actually face is flat subscription vs. usage billing. This page does that one comparison, with sourced numbers and honest caveats.

How the math works

Monthly API cost = requests/day × 30.4 × (input tokens × input rate + output tokens × output rate). Subscriptions are flat-priced, so they appear at their sticker price with a caveat about usage caps. No accounting for prompt caching (typically 90% off cached input) — real API bills for repetitive workloads can be lower.

Rule of thumb

Light chat users: free tiers usually suffice. Regular users: a ~$20 plan beats the API on flagship models. Heavy agentic coding: you exceed $20 of API value fast, but you'll also hit plan caps — that's when $100–200 tiers or usage billing on a cheap model win.
