Claude Opus 4.7 — Anthropic Frontier Model on Craze

About Claude Opus 4.7

Claude Opus 4.7 is Anthropic's most capable Claude model and the one to reach for when a task needs real thinking — multi-step research, deep code refactors, careful long-form drafting, or agents that have to plan several moves ahead before acting.

Inside Craze, Opus 4.7 sits next to GPT 5.5 as the other frontier option you'd pick when the quality of the answer matters more than the latency. It supports tool use, MCP servers, vision, and structured outputs, so on Craze it pulls from every connector you've added, writes back to docs, sends emails, and coordinates with other agents — without you wiring the integration manually.

Pair Opus with a faster model (Haiku, or GPT 5.5 in a routing role) when you want one model to plan and another to execute the routine steps. Or run it solo for the deepest single-model work — long briefs, careful research, code that has to be right the first time.

What Claude Opus 4.7 is good at

Frontier-grade reasoning

Opus 4.7 thinks through long chains of logic — research questions, agent plans, multi-step code reviews — without dropping the thread. The Claude you reach for when the answer has to be correct, not just plausible.

Long-document understanding

Reads and reasons across long inputs — full briefs, transcripts, codebases — and keeps the structure of the source intact in its answer. Useful for editorial work and deep research.

Careful long-form writing

Holds tone, structure, and voice over multi-page drafts. Strong for executive memos, customer-facing copy, and any output that has to read as written by a careful human.

Tool use, MCP, and structured output

Calls functions, returns strict JSON, and works with MCP servers. On Craze, Opus plugs into every connector you've added so agents can take real action across your stack.

Vision and document reading

Reads screenshots, scans, charts, and PDFs alongside your text. Useful for design review, sanity-checking data, and document Q&A inside the same conversation.

Use Claude Opus 4.7 on Craze

On Craze, Claude Opus 4.7 shows up wherever you'd reach for an AI model — the chat composer, the model picker, every connected workflow. Pick it once and your conversation, drafts, and agents follow you across the rest of the workspace.

Build AI agents on top of Claude Opus 4.7 that hand off context to teammates, pull from the apps you've already connected, and keep working in the background while you focus on something else.

Or hand Claude Opus 4.7 a routine task and switch to another model when the next step needs different strengths — you can mix and match models in the same conversation without losing context.

When to choose Claude Opus 4.7

Choose Opus 4.7 when you want Anthropic's deepest reasoning — the kind of task where you'd rather wait a beat for a better answer. Use GPT 5.5 in the same lane if you prefer OpenAI's voice or want a second opinion. Drop down to Sonnet 4.6 for everyday work and Haiku 4.5 when latency and cost matter more than depth.

Common questions about Claude Opus 4.7

What is Claude Opus 4.7?

Claude Opus 4.7 is Anthropic's flagship reasoning model — built for deep work like long-form writing, complex coding, careful research, and agents that plan multi-step jobs. On Craze you pick it from the model selector or let agents route work to it automatically.
How much does Claude Opus 4.7 cost on Craze?

Opus 4.7 is included in every paid Craze plan — no per-token billing on your end. One Craze membership covers it alongside GPT 5.5, Sonnet, Haiku, and everything else in the catalog.
When should I use Opus 4.7 instead of Sonnet or Haiku?

Reach for Opus 4.7 when the quality of the answer matters more than the latency or cost — deep code refactors, careful research, long-form drafting, agents that have to plan ahead. Sonnet 4.6 is the balanced everyday workhorse; Haiku 4.5 is the fast-and-cheap one for high-volume tasks.
Does Claude Opus 4.7 support tool use and agents?

Yes. Opus 4.7 supports tool calling, MCP servers, vision, and structured outputs. On Craze it ties into every connector you've added so agents can read context and take action across Gmail, Calendar, Notion, Slack, and the rest of your stack.
How does Opus 4.7 compare to GPT 5.5?

Both are frontier models in the same lane — pick whichever style fits the task. Opus tends to be more deliberate and careful with long-form text and research; GPT 5.5 tends to be quicker to take initiative on multi-step coding and tool use. The good news on Craze: you can switch between them in the same chat.
Do I need an Anthropic API key to use Claude Opus 4.7 on Craze?

No. Craze handles authentication, billing, and rate limits for you. Sign up and Opus 4.7 is one click away from the model picker — no key to manage, no separate Anthropic account.
