Official Model Pricing Methods

This page explains upstream vendor pricing rules only. It does not describe Crazyrouter resale prices.

Upstream pricing: the vendor’s own input, output, cached input, tool call, search grounding, prompt caching, and similar billing rules
Crazyrouter pricing: Crazyrouter’s own sell price, multiplier, discount, channel variation, and settlement logic

This page reflects vendor documentation checked on 2026-04-27. Vendors can change prices, preview-model policies, long-context rules, search-tool fees, and caching behavior. Recheck the official source links before relying on any number in production.

Official Example Price Table

The examples below intentionally use the most common pricing tier that is easiest to map to budget planning:

Anthropic: standard API price, excluding Fast mode, US-only inference, and Batch discounts
OpenAI: Standard price, excluding Batch, Priority, and Regional Processing surcharges
Gemini: Standard price, usually the text/image/video default path, and for Gemini 3* models the <= 200K prompt tier
xAI: if the public static docs do not list a standalone price for the exact routed name, this page says so explicitly
Z.AI: the official Text Models price
MiniMax: the main table uses Pay as You Go; subscription-style pricing is listed separately under Token Plan

Unless otherwise noted, prices below are USD / 1M tokens.

Anthropic Example Prices

Crazyrouter Name	Official Model	Base Input	Cache 5m / 1h / Hit	Output	Notes
`claude-opus-4-8`	`claude-opus-4-8`	`$3`	`$3.75 / $6 / $0.30`	`$15`	`1M context` uses the standard rate; Batch is roughly `50% off`
`claude-opus-4-8`	`claude-opus-4-8`	`$5`	`$6.25 / $10 / $0.50`	`$25`	`Fast mode` is billed at `6x` the standard price
`claude-opus-4-8`	`claude-opus-4-8`	`$5`	`$6.25 / $10 / $0.50`	`$25`	`US-only inference` has an extra regional multiplier in the official docs
`claude-opus-4-8`	`claude-opus-4-8` snapshot	`$3`	`$3.75 / $6 / $0.30`	`$15`	Snapshot IDs keep the `Sonnet 4.5` price; they do not define a separate pricing table

OpenAI Example Prices

Crazyrouter Name	Official Model	Input	Cached input	Output	Notes
`gpt-5.5`	`gpt-5.5`	`$2.50`	`$0.25`	`$15.00`	Standard price applies below `270K` context; long-context multipliers apply above that
`gpt-4o`	`gpt-4o`	`$2.50`	`$1.25`	`$10.00`	Classic three-part token pricing
`gpt-5`	`gpt-5`	`$1.25`	`$0.125`	`$10.00`	Tool charges are separate
`gpt-5.5`	`gpt-5.1-codex-max`	`$1.25`	`$0.125`	`$10.00`	Commonly used in Codex and agentic coding workflows, but still billed with the standard three-part structure
`gpt-5-mini`	`gpt-5-mini`	`$0.25`	`$0.025`	`$2.00`	Lower-cost GPT-5 variant
`gpt-5-nano`	`gpt-5-nano`	`$0.05`	`$0.005`	`$0.40`	Lowest-cost GPT-5 route
`gpt-5.5`	`gpt-5.5`	`$1.75`	`$0.175`	`$14.00`	Earlier flagship tier, still standard three-part token pricing
`gpt-5.5`	`gpt-5.5`	`$5.00`	`$0.50`	`$30.00`	Current flagship tier; the official standard-price note applies below `270K` context

Gemini Example Prices

Crazyrouter Name	Official Model	Standard Input	Standard Cache	Standard Output	Notes
`gemini-3.1-pro`	`gemini-3.1-pro`	`$2.00`	`$0.20` + `$4.50 / 1M tok / hr` storage	`$12.00`	`<= 200K` prompt tier; `> 200K` becomes `$4 / $0.40 / $18`; Google also lists Search and Maps free quotas plus `$14 / 1,000 search queries`
`gemini-2.5-flash-lite`	`gemini-2.5-flash-lite`	`$0.10` for text / image / video	`$0.01` for text / image / video + `$1.00 / 1M tok / hr` storage	`$0.40`	Audio input is `$0.30`, audio cache is `$0.03`; Search is `1,500 RPD` free then `$35 / 1,000 grounded prompts`

xAI Example Prices

Crazyrouter Name	Official Mapping	Prompt / Cached / Output	Tool Fees	Notes
`grok-4.1-fast`	Internal reasoning route	The public static docs do not list a standalone `grok-4.1-fast` token price	`web_search $5 / 1k`, `x_search $5 / 1k`, `code_execution $5 / 1k`, `attachment_search $10 / 1k`, `collections_search $2.50 / 1k`	`reasoning tokens` are billed at the `completion token price`
`grok-4.1`	Internal Grok 4.1 route	The public static docs do not list a standalone `grok-4.1` token price	same as above	The Crazyrouter route name should not be treated as a public xAI static SKU

What the current xAI static docs reliably expose is the token-category structure, tool-invocation pricing, Batch 50% off, and the instruction to check model details or the console for model-specific token prices. Since grok-4.1 and grok-4.1-fast are not individually priced in the static public docs, this page does not assign another SKU’s numbers to them.

Z.AI / GLM Example Prices

Crazyrouter Name	Official Model	Input	Cached input	Cached input storage	Output	Notes
`glm-5`	`GLM-5`	`$1.0`	`$0.2`	`Limited-time Free`	`$3.2`	`Web Search` is billed separately at `$0.01 / use`

MiniMax Example Prices

Pay as You Go

Crazyrouter Name	Official Model	Input	Prompt caching read	Prompt caching write	Output	Notes
`MiniMax-M2.7`	`MiniMax-M2.7`	`$0.3`	`$0.06`	`$0.375`	`$1.2`	This is the clearest tier to use for direct API budgeting

Token Plan

Plan	Monthly Price	`M2.7` Quota
Starter	`$10 / month`	`1,500 requests / 5hrs`
Plus	`$20 / month`	`4,500 requests / 5hrs`
Max	`$50 / month`	`15,000 requests / 5hrs`

Anthropic

Anthropic pricing is not just a simple input / output split. The official structure breaks out:

Base Input Tokens
5m Cache Writes
1h Cache Writes
Cache Hits & Refreshes
Output Tokens

Two common rules also matter:

Batch API usually bills input and output at roughly 50% off
Prompt caching follows the public multiplier rules: 5-minute cache write = 1.25x input, 1-hour cache write = 2x input, and cache hit = 0.1x input

Crazyrouter Name	Official Mapping	Official Billing Method	Notes
`claude-opus-4-8`	Anthropic `claude-opus-4-8`	billed as `base input / 5m cache write / 1h cache write / cache hit / output`	Anthropic explicitly documents `Sonnet 4.6` with `1M context`, still using standard pricing
`claude-opus-4-8`	Anthropic `claude-opus-4-8`	billed as `base input / 5m cache write / 1h cache write / cache hit / output`	`Opus 4.6` also supports `1M context`; `Fast mode` uses a separate multiplier
`claude-opus-4-8`	Anthropic `claude-opus-4-8`	billed as `base input / 5m cache write / 1h cache write / cache hit / output`	`Opus 4.7` is a distinct model on the official Anthropic pricing surface
`claude-opus-4-8`	Anthropic snapshot ID `claude-opus-4-8`, usually displayed publicly as `claude-opus-4-8`	still billed under the `Sonnet 4.5` `base input / cache write / cache hit / output` structure	Snapshot IDs are dated API names, not separate product prices

OpenAI

OpenAI pricing is the most uniform of the set. The public structure is usually:

Input
Cached input
Output

Common extra rules:

Responses API itself does not add a separate model fee; billing still follows the selected model’s token rates
Web search, containers/code execution, Computer Use, and other tools are billed separately
Batch API usually discounts token pricing by about 50%

Crazyrouter Name	Official Mapping	Official Billing Method	Notes
`gpt-5.5`	internal alias, usually meaning OpenAI `gpt-5.5`	billed as `input / cached input / output`	the public standard price applies below `270K` context; regional processing endpoints add another surcharge
`gpt-4o`	OpenAI `gpt-4o`	billed as `input / cached input / output`	classic unified OpenAI pricing structure
`gpt-5`	OpenAI `gpt-5`	billed as `input / cached input / output`	tool usage is billed separately; there is no separate public “thinking token price” line item
`gpt-5.5`	should map to OpenAI `gpt-5.1-codex-max`	billed as `input / cached input / output`	Codex-oriented naming, but the public price structure still matches the regular GPT-5.1 token format
`gpt-5-mini`	OpenAI `gpt-5-mini`	billed as `input / cached input / output`	smaller lower-cost tier
`gpt-5-nano`	OpenAI `gpt-5-nano`	billed as `input / cached input / output`	nano tier, same billing structure
`gpt-5.5`	OpenAI `gpt-5.5`	billed as `input / cached input / output`	still part of the GPT-5 pricing pattern
`gpt-5.5`	OpenAI `gpt-5.5`	billed as `input / cached input / output`	current flagship tier; use the latest long-context notes from OpenAI before production rollout

Google Gemini

Gemini pricing differs the most from OpenAI and Anthropic because Google often publishes multiple processing modes:

Standard
Batch
Flex
Priority

And it often breaks out:

Input
Output (including thinking tokens)
Context caching price
Context caching storage
Grounding with Google Search
Grounding with Google Maps

Crazyrouter Name	Official Mapping	Official Billing Method	Notes
`gemini-3.1-pro`	Google `gemini-3.1-pro`, often displayed internally as `gemini-3.1-pro`	officially split by `Standard / Batch / Flex / Priority`, and then by `input / output / caching / search grounding / maps grounding`	preview model, with separate `<= 200K` and `> 200K` prompt pricing tiers
`gemini-2.5-flash-lite`	Google `gemini-2.5-flash-lite`	priced by `Standard / Batch / Flex / Priority`, with separate `input / output / context caching / storage / Google Search / Google Maps`	stable model rather than preview; official output pricing explicitly includes thinking tokens

xAI Grok

xAI pricing is best understood as token categories plus tool billing, rather than a separate pricing table for every visible route name:

Prompt tokens
Cached prompt tokens
Completion tokens
Reasoning tokens

xAI also explicitly states:

Reasoning tokens are billed at the completion token price
Web Search, X Search, Code Execution, and similar server-side tools are billed separately per 1,000 calls
Batch API usually applies a 50% token discount

Crazyrouter Name	Official Mapping	Official Billing Method	Notes
`grok-4.1-fast`	internal reasoning route; conceptually closest to a Grok 4.1 reasoning configuration	billed using the xAI token-category model: `prompt / cached prompt / completion / reasoning`, plus tool invocation fees when relevant	the public xAI pricing docs emphasize SKU-style names such as `grok-4-1-fast-reasoning`; this route name should not be treated as an official standalone public SKU
`grok-4.1`	internal Grok 4.1 route; conceptually closer to a non-thinking Grok 4.1 configuration	still follows the same xAI token-category billing logic, with tools billed separately	for production budgeting, rely on the current xAI public token and tool rules, not on the internal route name alone

xAI Consumption and Rate Limits: docs.x.ai/developers/rate-limits
xAI Prompt Caching Pricing: docs.x.ai/developers/advanced-api-usage/prompt-caching/usage-and-pricing

Z.AI / GLM

Z.AI GLM-5 pricing is close to the OpenAI pattern, but it adds cache storage as its own line item:

Input
Cached Input
Cached Input Storage
Output

Built-in tools such as Web Search are priced separately per use.

Crazyrouter Name	Official Mapping	Official Billing Method	Notes
`glm-5`	Z.AI `GLM-5`	billed as `input / cached input / cached input storage / output`	official `Web Search` is charged separately, so token price alone is not the full cost picture

GLM-5 Overview: docs.z.ai/guides/llm/glm-5

MiniMax

MiniMax is the one vendor here where two official commercial modes matter:

Pay as You Go
Token Plan

That means:

Pay as You Go is the normal token-priced API path
Token Plan is subscription-style and, for M2.7, often described as a requests per 5-hour rolling window capacity product rather than plain token billing

Crazyrouter Name	Official Mapping	Official Billing Method	Notes
`MiniMax-M2.7`	should map to `MiniMax-M2.7`	under `Pay as You Go`, billed as `input / output / prompt caching read / prompt caching write`; under `Token Plan`, billed as `requests / 5hrs` capacity	for production API budgeting, start with `Pay as You Go`; evaluate `Token Plan` separately for heavy coding or interactive usage

Summary

If you only need a quick mental model of how each vendor bills, the shortest version is:

Anthropic: base input + cache write/read + output
OpenAI: input + cached input + output, with tools billed separately
Gemini: multiple processing modes + input/output + caching + search/maps grounding
xAI: prompt/cached/completion/reasoning, with server-side tools billed separately
Z.AI: input + cached input + cached storage + output
MiniMax: token pay-as-you-go or subscription-style capacity plan
