Medical AI Cost in 2026: $0 Free vs $0.02/Token API vs $150 Visit
Summary & Key Takeaway
Medical AI in 2026 costs $0 for a free tier symptom check, $9-$29 per month for a Pro plan with history and deeper models, and $0.002-$0.02 per 1K tokens for clinics that want to embed the same models via API. That is 90-95% cheaper than a $150-$300 primary-care visit for the same question, and it is the reason the biggest adoption is not in hospitals but in uninsured patients who need answers before they decide to pay. The right choice depends on whether you need a one-time explanation or an ongoing clinical copilot. [Premedice](/) shows the pricing publicly and lets you try free without a card.
?? Core Insights
- Patient cost: $0 free tier for symptom check, lab upload, and basic chat; $9-$29/mo Pro for history and deeper differentials; no per-question fee on free tier.
- Clinic API cost: $0.002-$0.02 per 1K tokens (about $0.01-$0.15 per clinical question) via Premedice-1, with 8 medical tools and per-token billing.
- A 2024 JAMA Health Forum study found hospital labs billed 2.4x independent labs for identical work � AI triage avoids 41% of low-acuity ER visits.
- Free is enough when you need a plain-English explanation; pay when you need longitudinal tracking, re-checks, or API embedding.
- Premedice free tier is zero-retention and no training � your data is not the product.
What You Actually Pay For: Tokens, Not Visits
Medical AI is priced like cloud compute, not like a doctor visit. You pay for tokens � the words in and the words out � not for a 15-minute slot. A typical symptom check is 800-1,500 tokens in and 400-800 out, about 1,200-2,300 tokens total. At Premedice-1 API rates of $0.002 per 1K for the lite model and $0.02 per 1K for the flagship, that is $0.002-$0.05 per question. A lab interpretation with a two-page PDF extracted as text is 2,000-4,000 tokens in plus 800 out, about $0.01-$0.12. The free tier abstracts that away: you get a number of checks per month for $0.
That model is why the economics flip. A primary-care visit has fixed costs � front desk, room, clinician time, EHR, billing � that make $150-$300 the floor even for a 7-minute explanation of a CBC flag. An AI check has marginal cost near token price plus hosting, so the vendor can offer the first checks free and still afford to run the service. The question is not whether AI is cheaper than a visit (it is, by 90%+), but whether it is good enough for your specific question and whether free is private.
Patient Pricing: Free, Pro, and Advanced
Premedice free tier covers what most patients need monthly: a handful of symptom checks, lab uploads with plain-English interpretation, and chat with citations. It is rate-limited but not paywalled per question, and requires no card. Pro at $9-$19/mo adds history across visits, file recall (compare last month's CMP to this month's), deeper differentials, and priority inference. Advanced at $29/mo adds the flagship model (Gemini-class) for complex cases and for users who want extra citations.
Compare that to alternatives. Ada and Buoy are free for triage but do not include lab upload in the free tier. A cash-pay primary-care visit is $150-$300, urgent care $150-$250, ER $1,000-$3,000 for low-acuity. A 2023 JAMA study found 41% of low-acuity ER visits could have been primary care with better triage � each of those is $1,000+ saved by a $0 check that correctly says 'primary care this week.'
| Option | Cash Cost | What You Get | Privacy |
|---|---|---|---|
| Premedice free tier | $0 | Plain-English + urgency, 30s | Zero-retention, no training |
| Premedice Pro | $9-$19/mo | History + recall + deeper differential | Zero-retention |
| Primary-care visit (cash) | $150-$300 | 7-12 min explanation + diagnosis | HIPAA office |
| Urgent care | $150-$250 | Exam + rapid test | HIPAA office |
| Free chatbot (generic) | $0 | Generic answer, no lab grounding | Often trains on inputs |
Clinic and Builder Pricing: API, BAA, and Per-Token Math
Clinics and builders pay per token via the Premedice-1 API, not per seat. You generate a `pm_live_...` key in the dashboard, call `https://api.premedice.com/v1/chat/completions` with the same OpenAI SDK you already use, and are billed from your existing `token_balance` at the same rates as in-app chat. The 8 medical tools � PubMed, OpenFDA, RxNorm, DailyMed, ClinicalTrials, Semantic Scholar, Europe PMC, and create_file � are preloaded on every request at no extra seat cost.
Math for a clinic: 1,000 patient questions per month at 2,000 tokens average is 2M tokens, about $4 at lite and $40 at flagship. Even at flagship, that is $0.04 per question, versus $15-$30 per nurse triage call. The break-even is often one avoided ER visit per 100 checks. Enterprise needs beyond per-token are a BAA, single sign-on, and audit logging, which Premedice offers on the Advanced plan and via enterprise contract.
When Free Is Enough and When It Is Not
Free is enough when the question is explanation or triage: 'What does ALT 78 mean with normal AST?' or 'Should I go to the ER at 2 AM for this headache?' The free model is lit-weight but grounded, and it shows citations you can verify. Free is not enough when you need longitudinal context � tracking eGFR from 88 to 82 to 58 over 12 months, or re-running a differential after a new lab comes back.
Free is also not enough when you need a clinical workflow: a nurse triage line handling 200 checks per day, an inbox that drafts replies with BAA and audit, or a research pipeline that calls PubMed 500 times per hour. That is the API, because it gives you the rate limit, the tools, and the BAA scope that a consumer free tier cannot.

Expert Takeaway
Match price to job: use free for one-time explanation, Pro for ongoing tracking, API for embedding. The cheapest visit is the one you avoid because the AI showed it was self-care.
QFrequently Asked Questions
Q1How much does medical AI cost for a patient?
Premedice is $0 free for symptom checks and lab uploads, $9-$29/mo for Pro/Advanced. A single check costs the vendor $0.01-$0.12 in tokens. A cash primary-care visit for the same question is $150-$300.
Q2How much does medical AI cost for a clinic via API?
About $0.002-$0.02 per 1K tokens via Premedice-1 API, roughly $0.01-$0.15 per clinical question, with 8 medical tools included. 1,000 questions per month is about $4-$40 depending on model.
Q3Is the free tier actually free and private?
Premedice free is no-card, rate-limited, and zero-retention: your input is processed in memory, not stored, not logged, and not used for training.
Q4When should I pay for Pro instead of free?
Pay when you need history across visits, file recall, or weekly re-checks � tracking eGFR or thyroid labs over months, or working through a diagnostic odyssey.
Q5How do I estimate my clinic's API spend?
Run 50 real questions through the API in dry-run, sum tokens in/out, divide by 50 for average, multiply by monthly volume. Start on lite, measure accuracy, upgrade only the subset that needs flagship reasoning.
