Start with the task path and prerequisite context before you jump into product surfaces.
Use this page as the buyer workflow after you understand the basic difference between credits, tokens, and minutes. For the longer unit primer, start with AI Credits vs Tokens vs Minutes; this checklist is about comparing live plans without letting different unit labels distort the decision.
The goal is not to convert every unit into one universal AI currency. The goal is to turn each vendor's plan into the same five questions: what unit is counted, when it resets, what your workload consumes, whether the app and API are separate, and what actually changes at the next paid tier.
Identify the unit before you compare prices
Start by copying the vendor's exact unit language into your notes. Do not shorten "monthly generative credits," "API credits," "Fast GPU time," "premium requests," or "input and output tokens" into a generic usage bucket. The adjective usually tells you which wallet, route, model, or reset rule matters.
Then find the burn rule for the task you will actually run. Runway's app help describes video credit use by duration, while its API pricing lists model-specific credits per generated second. OpenAI's API pricing separates API usage from ChatGPT subscriptions and prices by model-specific token usage. Midjourney treats GPU time as active generation time, not the time spent browsing, prompting, or waiting.
If the pricing page does not show the burn rule, pause the comparison. A plan with more credits can still be worse if the workload you need consumes those credits faster, is locked behind a higher plan, or lives in a separate API account.
Find the reset window and wallet
Next, identify the reset window, expiration rule, and wallet owner. Adobe's generative credit help explains monthly credits, in-product counters, reset dates, and no rollover for generative credits. Midjourney's Fast time resets with the subscription cycle. Runway notes that credits in a workspace can be shared by editors and that web app credits do not appear in API credits.
Write down whether the allowance is daily, monthly, annual, one-time, purchased, promotional, workspace-level, per-seat, or developer-organization level. Those labels decide whether unused usage disappears, carries over, is pooled across a team, or can be topped up when a deadline spikes.
This is also where a cheap plan can fail. A free daily allowance may be fine for experiments but weak for batch work. A large shared workspace pool may look generous until one power user consumes it. A purchased top-up may be useful only if the vendor states how long it remains valid and which balance is spent first.
Estimate the workload you will actually run
Build the estimate from the deliverable, not from the plan table. For text, estimate input size, output size, model choice, file attachments, tool calls, and retries. For video, estimate seconds generated, resolution, audio, model, number of attempts, and exports. For coding assistants, count prompts, code review actions, agent sessions, and model multipliers if the vendor uses request-style billing.
Pricing unit | What to write down | Reset or wallet check | Real workload estimate | Next-tier question |
|---|---|---|---|---|
Credits or compute units | Exact credit wallet and the feature, model, duration, or quality setting that burns it | Monthly included balance, purchased top-up, rollover, expiration, shared pool, and spending order | Jobs per month times credits per job, plus retries, failed generations, upscales, and exports | Does the upgrade buy more usable allowance, better models, priority, top-up discounts, or only a larger headline number? |
Tokens | Input, output, cached, image, audio, reasoning, or tool-token rates by model | API billing account, free trial credit, budget limit, rate limit, and whether app subscriptions are excluded | Average prompt, context, files, output length, tool calls, retries, and batch volume | Does a different model or API route lower cost enough, or does the tier only raise access limits? |
Minutes or seconds | Whether the meter counts generated output length, input media length, realtime session time, or per-second API generation | Monthly media allowance, per-second meter, unused carryover, and duration caps | Clip length, audio, resolution, model, takes per final asset, and discarded outputs | Does the next tier unlock longer duration, higher resolution, faster queues, or enough extra minutes for production? |
GPU hours | Active processing time, Fast/Turbo/Relax mode, concurrency, and what tasks consume compute | Subscription reset, no-carryover rules, extra GPU-hour purchase, and Relax eligibility | Expected render jobs, mode choice, active generation time, variation rate, and video usage | Does the tier add enough fast time or relaxed throughput, or are you paying mainly for speed and concurrency? |
Seats | Whether pricing is per user, a minimum seat count, or a flat team plan with included members | Billing cadence, seat minimums, proration, admin roles, guests, and shared allowance ownership | Active creators, reviewers, admins, occasional users, and systems that should not need a human seat | Does the upgrade buy governance, permissions, support, or shared billing rather than more generation capacity? |
Premium requests | Which actions count as requests, which models multiply usage, and whether the vendor has changed the billing unit | Monthly allowance, reset time, overage price, excluded plans, and any billing-model change notice | User prompts, follow-up prompts, review runs, agent sessions, steering comments, and premium model selection | Does the next tier add enough allowance, cheaper overage, or model access for the heavy actions you repeat? |
Keep one pessimistic column in your spreadsheet. Add a retry factor, a failed-job factor, and a busy-month factor. The right plan is the one that still works when the team has to revise outputs, rerun prompts, regenerate clips, or answer a client request late in the cycle.
Separate app, team, and API routes
Do not assume one vendor account means one budget. App subscriptions usually buy human access to a product surface. API usage usually bills a developer account, project, organization, or cloud route. Team plans may add seats, admin controls, shared workspaces, and pooled usage without changing the API meter.
OpenAI states that API usage is billed separately from ChatGPT subscriptions. Runway states that web app credits and API credits are separate. Krea AI's pricing page shows compute units for creative plans and a Business route with many seats included under a flat team plan. Those are different purchase questions even when the same brand sits above them.
A clean buyer estimate has separate rows for people and systems. People need seats, permissions, history, collaboration, and support. Systems need API keys, budget caps, logs, rate limits, retry controls, and alerting. Shared creative pools need owner rules so a heavy user does not drain the balance before the rest of the team can work.
Compare the next paid tier
After the unit math is done, compare the next paid tier against the current bottleneck. If the bottleneck is usage volume, the upgrade needs to add a larger usable allowance or cheaper top-ups. If the bottleneck is quality, the upgrade needs to unlock the model, resolution, feature, or premium route that changes the final output. If the bottleneck is team risk, the upgrade needs to add seats, permissions, governance, billing controls, or support.
Avoid comparing only the cheapest visible paid plan. The useful comparison is usually the plan you would actually need after a normal month of work. A creator who exceeds a video credit cap every week, a developer running token-heavy API jobs, and a manager adding ten collaborators are not evaluating the same price even if each pricing page starts with the same monthly number.
Use a final one-line decision statement before paying: "We need three creator seats, one shared monthly credit pool for video drafts, occasional purchased overflow, and a separate API budget for production calls." If that sentence names the unit, wallet, reset window, workload, and next-tier boundary, the pricing comparison is grounded enough to survive unlike units.
FAQ
Common questions
Should I convert every AI pricing unit into dollars per output?
Use dollars per output only after you have the real burn rule. Credits, tokens, minutes, GPU hours, seats, and premium requests are not interchangeable by label; they become comparable only when tied to a specific workflow, model, reset window, and retry rate.
What reset rule matters most when comparing AI plans?
Start with whether the allowance resets daily, monthly, annually, or never. Then check whether unused usage rolls over, whether purchased top-ups expire, whether balances are shared across a workspace, and which wallet is consumed first.
Do app credits usually cover API usage?
Do not assume that. Many vendors separate human app subscriptions from developer API billing. Treat app usage, team seats, shared workspace credits, and API projects as separate budget lines unless the official pricing source explicitly combines them.
How should teams compare seats against usage units?
Seats answer who can access the workspace; usage units answer how much work the product will perform. A team estimate should count active users, administrators, shared usage pools, and API systems separately before choosing a paid plan.
When is the next paid tier the right comparison point?
Use the next tier when the current plan fails for a specific reason: too little allowance, missing model access, insufficient duration or resolution, weak governance, no top-ups, or poor API separation. If the next tier does not solve the bottleneck, keep looking.
