Claude Opus 4.7 Context Window, Pricing, and Availability

As of April 16, 2026, Anthropic's current models overview lists Claude Opus 4.7 at a 1M-token context window, 128k max output, and $5/$25 per million input/output tokens. The same official docs and product pages say it is available across Claude, the Claude API, Vertex AI, Microsoft Foundry, and Bedrock, with an AWS research-preview nuance called out in the docs.

Exact specs Anthropic publishes

The live source of truth here is Anthropic's current models overview. Anthropic lists Claude Opus 4.7 with a 1M-token context window, 128k max output, API ID claude-opus-4-7, moderate latency, adaptive thinking, and January 2026 as both the reliable knowledge cutoff and training data cutoff.

What the pricing means in practice

The important pricing story is not that Opus 4.7 is cheap. It is that Anthropic kept the flagship price flat while shipping a stronger model. the Claude Opus product page and Anthropic's Claude Opus 4.7 launch post both say pricing remains the same as Opus 4.6 at $5 input and $25 output per million tokens.

That makes Opus 4.7 easier to justify for existing Opus users, but it does not suddenly make it the default for budget-sensitive traffic. Sonnet 4.6 still exists for the "good enough, faster, and cheaper" slot.

Availability across platforms

Anthropic says Opus 4.7 is available today in Claude itself, the Claude API, Amazon Bedrock, Google Cloud Vertex AI, and Microsoft Foundry. The launch post and product page state that directly, while Anthropic's current models overview publishes the API ID plus AWS and Vertex naming details.

The exact wording matters because the same docs say Claude Opus 4.7 on AWS is available through Claude in Amazon Bedrock, currently in research preview. So availability is real, but the rollout is not identical across every platform.

How it compares with Sonnet 4.6 and Haiku 4.5

Anthropic's current model matrix positions Opus 4.7 above Sonnet 4.6 and Haiku 4.5 in capability, but not as the obvious answer for every task. Sonnet 4.6 keeps the "best combination of speed and intelligence" slot, while Haiku 4.5 stays the fast, lower-cost option.

So the way to read Opus 4.7's specs is not "better than everything else, therefore default." The right reading is "best generally available Claude model when your workflow actually needs the top tier."

The launch-day nuances to watch

The first nuance is platform lag. Dedicated Bedrock, Vertex AI, and Foundry setup guides can trail the central models overview on launch day. The second nuance is safety documentation. Anthropic's system cards page did not yet show an Opus 4.7 entry when I checked after launch, even though the product page links to a model card.

Those gaps are normal for a same-day launch, but they matter if you are writing procurement notes or regulated deployment plans.

Limitations and Tradeoffs

Specs pages answer the easy questions, but they do not answer the hard ones about value. A 1M context window and 128k output are only worth paying Opus prices for if your workflow can actually use them. Otherwise Sonnet 4.6 may still be the better buy.
