AI Model Pricing Comparison 2026: OpenAI vs Claude vs Gemini Cost Calculator
Built by R.K., Creator & Business Economics Analyst · Updated June 2026Which AI provider costs less in 2026? For high-volume automation, Gemini 2.5 Flash-Lite and GPT-4.1 Nano are tied at the floor — $0.10/$0.40 per million tokens. At the mid tier, GPT-4.1 mini ($0.40/$1.60) undercuts Claude Sonnet 4.6 ($3.00/$15.00) by roughly 7× on input. At the flagship tier, GPT-5.4 ($2.50/$15.00) sits close to Sonnet 4.6, while Claude Opus 4.8 ($5.00/$25.00) and GPT-5.5 ($5.00/$30.00) sit above it. Batch tiers typically cut all three providers’ rates by around 50%, and prompt caching can cut repeated input cost by up to 90% on Anthropic and Google.
Picking an AI model without running the actual cost math gets expensive fast. A support agent handling 100,000 queries a month can land anywhere from roughly $90 to $600+ depending purely on which model processes it — before batch or caching are even applied. The right choice depends on your quality floor, your workload type, and which cost levers you’re willing to use.
This AI model pricing comparison calculator runs your actual workload against OpenAI, Anthropic, and Google side by side. Pick a workload preset or set your own, choose a model for each provider, and the cost difference shows up immediately — at your current volume and at scale.
AI pricing changes often, sometimes monthly. The rates built into this comparison are verified as of June 2026 — check the disclaimer below for direct links to each provider’s live pricing page before making a budget decision.

The Three Cost Levers Behind Any AI Model Pricing Comparison
The price gap between providers moves based on model tier, workload type, and which levers you’ve turned on. A team on Claude Sonnet 4.6 without caching can pay several times more per run than a team running the equivalent task on GPT-4.1 mini. The number that matters is the specific model versus specific model comparison at your actual token counts — which is what the calculator above computes.
Model Routing, Batch Tiers, and Prompt Caching
Model routing sends classification and short responses to nano/flash-tier models (around $0.10/$0.40) and reserves flagship models for tasks that need the depth. Batch or async tiers commonly cut token rates by roughly half for workloads that can tolerate slower turnaround. Prompt caching can reduce repeated system-prompt input cost by up to 90% on Anthropic and Google. Combined, these three levers can take a $500/month workload well under $100/month without changing providers or output quality.
How This Comparison Is Built
Model prices used in this calculator are verified directly against OpenAI, Anthropic, and Google’s official pricing pages as of June 2026 and re-checked periodically. Cached-rate figures are approximate — cache discount structures vary by model generation and provider, so confirm exact terms on the provider’s pricing page before budgeting a production workload. This tool is a planning aid for comparing relative cost, not a guarantee of your actual invoice, which depends on your specific usage pattern and any account-level agreements.

Frequently Asked Questions
Is OpenAI cheaper than Claude in 2026?
It depends on the tier. GPT-4.1 Nano at $0.10/$0.40 per million tokens is well below Claude Haiku 4.5 at $1.00/$5.00. At the mid tier, GPT-4.1 mini ($0.40/$1.60) undercuts Claude Sonnet 4.6 ($3.00/$15.00) by roughly 7x on input. At the flagship tier, GPT-5.4 ($2.50/$15.00) and Sonnet 4.6 land close together, while Claude Opus 4.8 ($5.00/$25.00) sits above GPT-5.4.
Is Gemini cheaper than OpenAI and Claude?
At the cheapest tier, Gemini 2.5 Flash-Lite at $0.10/$0.40 matches GPT-4.1 Nano. Gemini 2.5 Flash at $0.30/$2.50 sits below GPT-4.1 mini on cost. For high-volume workloads with caching and a batch tier enabled, Gemini is frequently among the lowest total-cost options, though it depends on your specific usage pattern.
How much does batch or asynchronous pricing save?
OpenAI, Anthropic, and Google all offer asynchronous processing tiers that commonly cut token costs by roughly half for workloads tolerating slower turnaround. Content pipelines, analytics, and bulk generation are typical fits.
How much does prompt caching save on AI costs?
Prompt caching can reduce cached input token cost substantially — often around 90% on Anthropic and Google for stable system prompts. A 2,000-token system prompt called 50,000 times a month can save well over $200/month on Claude Sonnet 4.6 input costs alone.
