Claude Opus 4.5 API Pricing: Platform Cost Comparison [2026]

2026-07-03

The Version Question First

If you searched "Claude Opus 4.5 pricing," here's the update: Opus 4.5 has been succeeded by Opus 4.6, 4.7, and the current flagship, Claude Opus 4.8 (released May 28, 2026). The good news for budgeting is that the entire Opus 4.x line has held the same headline rate — so whether your code pins 4.5 or the latest 4.8, the per-token math below applies.

All figures here come from Anthropic's official pricing page. Rates change, so verify there before finalizing a budget.

Current Claude API Rates

Per million tokens (MTok), input / output:

ModelInputOutputNotes
Claude Opus 4.8 (flagship)$5.00$25.001M context, no long-context surcharge
Claude Sonnet 4.6$3.00$15.00Best price/quality balance
Claude Haiku 4.5$1.00$5.00Cheapest current model
Claude Fable 5 / Mythos 5$10.00$50.00Top tier; reserve for hardest work

Opus 4.8's rate is unchanged from 4.5/4.6/4.7 — a level Anthropic dropped to from the Opus 4.1 era's $15/$75, roughly a 67% cut. Opus 4.8 adds a cheaper Fast mode ($10/$50) and effort controls, but note its default effort moved to "high," which can quietly raise costs unless you set it.

The Discounts That Actually Move Your Bill

Two levers stack and can cut effective spend dramatically:

  • Batch API — 50% off input and output, for asynchronous jobs (within 24 hours). Opus drops to $2.50/$12.50.
  • Prompt caching — up to ~90% off cached input reads. For Opus, a cache hit is about $0.50/MTok instead of $5.00. Chatbots and agents that resend the same system prompt or context benefit most.

Watch two multipliers that push the other way: US-only inference (inference_geo: "us") adds ~10%, and cloud-marketplace regional endpoints (Bedrock, Vertex) add ~10% over global. A "$5/$25" model can land nearer $5.50/$27.50 for a US-resident workload before caching.

Platform Cost Comparison

The same Claude tokens cost the same base rate wherever you buy them — the differences are operational and in the discounts each route exposes:

RoutePricing behaviorBest for
Anthropic directList price; full Batch + cachingDirect control, newest models first
Amazon Bedrock~10% regional premium; AWS billingAWS-native stacks
Google Vertex AI~10% regional premium; GCP billingGCP-native stacks
Aggregator gatewaysOne key across providers; discounts varyMulti-model apps, unified billing

For teams already running image and video generation through a gateway like LinkModel — which aggregates models behind one API at up to 30% below official rates — consolidating billing and observability across providers is the operational win. Check the model catalog and pricing page for current availability and rates, since aggregator model coverage changes over time.

Which Claude Model Should You Pay For?

  • Haiku 4.5 ($1/$5) for high-volume classification, extraction, routing.
  • Sonnet 4.6 ($3/$15) as the general-purpose default — the price/quality sweet spot.
  • Opus 4.8 ($5/$25) for the hardest reasoning, agentic coding, long-horizon work.
  • Fable 5 / Mythos 5 ($10/$50) only when fewer failed agent loops justify 2x the token rate.

Routing simple tasks to Haiku and reserving Opus for genuinely hard prompts creates a 5–25x cost spread — the single biggest lever most teams leave unused. More tactics in how to reduce AI API costs.

In Context

Against peers, Claude sits at the premium end on raw tokens — Sonnet 4.6 ($3/$15) runs slightly above GPT-5.4 ($2.50/$15) and Gemini 3.1 Pro (~$2/$12), while budget options like DeepSeek V4 Flash ($0.14/$0.28) undercut everyone. Anthropic's counterweights are 1M-context at flat pricing, strong coding, and aggressive caching economics.
