Cheapest Model Finder

3 questions → the cheapest model for your job

Skip spreadsheet-comparing 25 models. Tell us what you're building - we'll return the cheapest 3 that fit.

What this calculator does

Use-case-driven model picker: tell it what you're building, get a ranked list of cheapest models meeting your quality floor — with cache + batch savings factored in.

Why use it
  • Lowest sticker price isn't always cheapest in production — cache hit rate, batch eligibility, modality matter
  • Use-case presets encode the actual workload (token shape, capability needs) so cheap-looking models that fail your task get auto-excluded
  • Per-model "why this works" reasons make the recommendation defensible to engineering and finance
  • Tier-1 / vision / agent constraints lock out models that fail compliance or capability requirements
Who uses this:
Vibe Coder High Quickest answer to "which is cheapest for my use case" — no manual price comparison Small Business High Defensible cheap-model choice with reasons that hold up to "why this and not that" Enterprise Medium Useful first pass; final selection often needs vendor-specific eval and compliance review

New to this calculator? Start with the ⚡ Playground — a few sliders, instant ballpark. Then switch to the 🧮 Calculator for your exact number.

Two ways to use this: visualize in the Playground, then get your number in the Calculator.

Cheapest Model Finder Playground
Three sliders, instant ballpark — priced on today’s cheapest model in your tier. The full finder matches your exact use case.
Cheapest model that still meets your bar

Two of these pick the model; one sets the scale. The estimate below uses all three together.

Cheapest tier that fits

💡Complexity sets the tier — 1-3 budget, 4-6 mid-tier, 7+ premium (~13× pricier per token). Required quality only raises that floor: 7+ rules out budget, 9+ forces premium. Tasks/day then multiplies the tier rate by your volume.

3 Any constraints?When checked, limits to OpenAI / Anthropic / Google. Excludes DeepSeek, xAI, Mistral, and others that may not have your required compliance posture.How to choose: Check this only if you have an actual constraint (data residency rule, BAA requirement, procurement allowlist). Otherwise leave unchecked — Tier-1 models are typically 2-10× more expensive than the absolute cheapest.Read the full guide →
Hint: Any must-haves like speed, privacy, or big context. Skip if none.

📋 What now?
  • Switch to the cheapest eligible tier — same capability bar, lower bill
  • Open the winner in the calculator — confirm the exact monthly cost for your volume
  • Keep a quality floor — your constraints already excluded anything too weak

Now that you have your ranked list…

What this means + what to do next

💡 What to consider beyond this ranked list for full TCO
  • Quality variance at YOUR task — sticker price tells you nothing about how the model performs on your prompts
  • Migration cost — switching to a new vendor often means weeks of prompt re-engineering and re-eval
  • Volume commitments — some vendors' enterprise pricing beats list price 30-50% at scale
  • Latency requirements — cheapest model may not meet your p95 latency SLA
Rule of thumb: Cheapest meeting your QUALITY bar (not just capability bar). Always run an eval on 50-100 representative tasks before committing.
Quantify the hidden costs:
  • Get exact $/month at your real token shape (not the use-case default) Cost Calculator
  • If your workload has repeat context, caching savings often dwarf model-swap savings Prompt Cache Roi
  • Cheapest-from-new-vendor often comes with lock-in cost — quantify it Vendor Concentration Risk
$ How this fits your overall ROI

Picking the cheapest valid model is half the work. The other half:

  • Does the cheapest model meet our quality bar on 100 real production examples?
  • What's the eval and migration cost if we switch from current vendor?
  • Will volume discounts from current vendor beat list-price savings from new one?
Bridge to ROI:
  • Rather than one cheap model, route easy queries cheap and hard queries premium Multi Model Router
  • Cache savings often beat model-swap savings on repeat-context workloads Prompt Cache Roi
  • Async-eligible portion of traffic gets 50% off — often bigger than the cheap-model gap Batch Vs Realtime
Doing something different?

If picking the cheapest isn't your real question:

  • You want to browse + filter, not get a single recommendation Ai Model Finder
  • Your traffic is mixed — easy and hard queries should use different models Multi Model Router
  • You've already picked a model and just want the dollar number Cost Calculator

Methodology

  • All prices are USD per 1 million tokens, current as of 2026-04-17.
  • Vendor-published values have no mark. Inferred/extrapolated values are marked with * and listed below.
  • Batch API discounts are 50% off standard rates across providers that offer Batch mode.
  • Prompt caching discounts vary by provider (typically 80-90% off cached input tokens).
  • Regional data-residency surcharges (Anthropic 1.1x, OpenAI 1.1x, Google regional tiers) are NOT included in base rates.
  • Long-context pricing tiers apply when input exceeds model threshold.
  • Embedding prices are input-only (no output tokens generated).

Primary sources

Last-verified date is the most recent successful daily snapshot (aicost_pricing_snapshots) or, when no snapshot exists yet, the latest successful crawler run (aicost_crawler_runs). 0 of 10 vendors are currently verified. Aggregator services (TokenCost, AI Pricing Guru, etc.) are not listed.

Inferred values (marked with * in calculator tables)

Derived from industry conventions, not directly published by the vendor. Typical conventions: cached input = 10% of base (90% off), Batch API = 50% of base (50% off).
