Not sure where to begin?

Answer 3 questions, get a model and a plan.

What you want to build, how much you code and your budget: you'll get the exact tools and the model to use.

Step 1 of 3

What are you building?

AI 101

New to AI? Six words that explain everything here

No jargon. Read this once and every page on AgentCost will make sense.

AI model

The “brain”. You send it text (or images, audio) and it sends back an answer. GPT, Claude, Gemini and DeepSeek are model families.

“Summarize this email” → a summary.

AI agent

A model plus tools and a loop: it plans, takes actions (edit files, browse, call APIs), checks results and keeps going until the task is done.

“Add a login page” → it writes code, runs it, fixes errors.

API

How your app talks to a model. You pay per use instead of a monthly seat, which is why your volume decides the bill.

Your support page sends each question to the model's API.

Tokens

The unit models are billed in — roughly ¾ of a word. Prices are “per 1M tokens”, with input (what you send) and output (what it writes) priced separately.

A 750-word article ≈ 1,000 tokens.

Context window

How much the model can read at once — its short-term memory. Bigger windows fit whole codebases or long documents in one request.

1M tokens ≈ several novels at once.

Benchmark

A standardized test that scores models on the same tasks, so you can compare quality fairly instead of trusting marketing.

Coding Index: how well a model solves real coding tasks.

Model or agent? The quick rule

You want an answer, text or a classification

→ A model

Call its API, or chat with it

You want a task done end-to-end

→ An agent

Use a ready agent or build one with a framework

You don't code and want a working app

→ An app-builder agent

Describe it, iterate by chatting

You want to cut cost

→ A smaller model

Use the “Best value” sort and test on real data

Usage trends

What developers are actually running

Real token volume across apps routed through OpenRouter (2026-10-29 – 2026-10-29). Not a survey — what production traffic is choosing right now.

Methodology

Sources, not opinions

Where do the prices come from?+

Straight from each provider's official pricing page, re-checked every few hours. Every model's “All prices” panel links the exact page it came from. If a page changes and our reader breaks, we keep showing the last verified prices and mark the provider below.

Where do the scores come from?+

We don't run benchmarks and never make up numbers. Intelligence, Coding and Agentic scores are Artificial Analysis's independent indexes; web and UI design scores are Design Arena's crowd-voted Elo ratings; “most used” ranks are real token volume from OpenRouter. Each is linked below.

How are “Our picks” chosen?+

From the models currently in view: the top performer has the highest score on the benchmark that fits your use case; best value has the most score per dollar among above-median models; the budget pick is the cheapest model that still scores above the median. Change filters or your workload and the picks update.

What do Frontier, Balanced and Efficient mean?+

A model's position in its own provider's lineup, read from the model family (Opus/Sonnet/Haiku, Pro/Flash/Lite, -mini…) and its price. It's a quick orientation aid — for actual quality, use the benchmark scores.

How is the monthly cost estimated?+

Your monthly input and output tokens × the model's per-million-token prices, with the cached share of input charged at the cache-read rate. It excludes tool fees, search grounding, images and taxes — always confirm on the provider's page before committing budget.

Is AgentCost affiliated with any AI provider?+

No. It's independent and free to use. No provider pays for placement or rankings.
