* Important: Calculated from the values currently shown. Default usage values are examples, so change them to match your expected usage. Built-in OpenAI web search, Anthropic Claude web search, and Google Gemini Grounding with Google Search rates were checked on June 20, 2026. Final charges may include regional and data-residency premiums, priority or batch processing, caching, orchestration, storage, citations, taxes, negotiated discounts, quality differences, and searches beyond the entered average.
Web-grounded AI has two cost layers: the model response and the search work used to retrieve current information. A single prompt can also trigger several searches, while providers treat retrieved context and free allowances differently.
Comparing the Complete Grounded-Response Cost
Enter monthly prompts, the share that requires current web information, average searches per grounded prompt, input tokens, retrieved web tokens, output tokens, and retry overhead.
The calculator applies each provider's current search fee and token treatment. Results include search-tool spend, model-token spend, total monthly cost, cost per grounded prompt, and first-year cost.
The comparison uses one representative current model per provider so it can produce an immediate estimate. It is a cost comparison, not a claim that the models provide equal quality.
How the Provider Billing Rules Differ
OpenAI currently charges $10 per 1,000 web-search calls. Search-content tokens are free, while normal prompt and output tokens use the selected model rates.
Anthropic currently charges $10 per 1,000 searches in addition to normal model tokens. Retrieved search results that enter Claude's context are billed as input tokens.
Gemini 3 currently includes 5,000 grounded prompts per month across the Gemini 3 family, then charges $14 per 1,000 search queries. One prompt may create several queries. Retrieved grounding context is not charged as input tokens.
Estimating Searches per Grounded Prompt
A simple current-fact lookup may need one search. A research question, comparison, shopping task, or multi-step agent may use several.
Use API usage data when available. For early planning, test a representative sample and record the average search count, retry rate, retrieved context size, and response size.
Search-trigger rate should reflect only prompts that actually need the web. Routing every request through search can add unnecessary cost and latency.
Built-In Models and Prices
The built-in comparison uses OpenAI GPT-5.4 mini, Anthropic Claude Sonnet 4.6, and Google Gemini 3.1 Flash-Lite Standard. Model and search-tool prices were checked on June 20, 2026 against official provider documentation.
Regional processing, data-residency premiums, batch or priority modes, negotiated discounts, and other model tiers are not automatically included. Use the custom option when a different model or account price is more relevant.
Practical Decisions This Tool Supports
- Estimate web-grounded AI cost before launch.
- Compare search-call and model-token pricing together.
- See the cost effect of several searches per prompt.
- Measure the value of limiting search to selected requests.
- Include retrieved-context tokens where the provider bills them.
- Compare public pricing with another model or private quote.
- Calculate cost per grounded prompt and first-year spend.
- Check the selected option against a monthly budget.
Costs and Limits Outside the Estimate
The result does not automatically include caching, agent loops beyond the entered retry rate, citation processing, storage, data transfer, orchestration, observability, taxes, regional premiums, or private discounts.
Search quality and model quality are not priced in. Review citation accuracy, freshness, latency, coverage, and answer usefulness before choosing a provider only from the lowest calculated total.
Frequently Asked Questions
What is a grounded AI response?
A grounded response uses current information retrieved from web search rather than relying only on the model's existing knowledge. The provider may charge for search calls, model tokens, or both.
Why can one prompt create more than one search query?
A model may issue several searches to answer one request, especially for comparisons, research, or multi-part questions. Google and Anthropic both note that a single model turn can perform multiple searches.
Why are retrieved web tokens billed differently?
OpenAI currently says search-content tokens are free, and Gemini says retrieved grounding context is not charged as input tokens. Anthropic bills web-search result content at the normal model input-token rate.
How is the Gemini free allowance handled?
The built-in Gemini 3.1 Flash-Lite option applies the current 5,000 grounded-prompt monthly allowance shared across Gemini 3. Searches from prompts beyond that allowance are billed using the average searches per grounded prompt.
Is the lowest-cost provider automatically the best choice?
No. This compares cost for representative current models. Search quality, model quality, citations, latency, regional availability, limits, safety, and product fit also matter.
Can I compare another model or search provider?
Yes. Add a custom option with its current model input and output prices, search price, free allowance, and whether retrieved search content is billed as model input.
