Claude Opus 4.7: What You Need to Know

Anthropic has released Claude Opus 4.7, the newest frontier model in the Claude family and a direct upgrade to Opus 4.6. Announced on April 16, 2026, Opus 4.7 focuses on the areas where developers actually spend their days: complex software engineering, long-running agent workflows, high-resolution vision, and honest, instruction-following reasoning.

If you build AI products, write software, or run agents that do real work, this release matters. It is one of the cleanest jumps in quality since the Claude 4 series launched - at the same price as Opus 4.6.

This guide breaks down what is new in Claude Opus 4.7, the benchmark wins, pricing, how it compares to the rest of the Claude lineup, and when you should actually use it.

What is Claude Opus 4.7?

Claude Opus 4.7 is Anthropic's latest general-availability frontier Opus model. It is positioned as Anthropic's strongest production model for coding and autonomous agents, sitting just below the more experimental Claude Mythos Preview in Anthropic's research ladder.

On the surface, Opus 4.7 is a direct upgrade to Opus 4.6:

• Same $5 / $25 per million input/output token pricing
• Same claude-opus-4-7 API naming convention
• Same availability across the Claude API, Amazon Bedrock, Google Vertex AI, and Microsoft Foundry

Underneath, a lot has changed. Anthropic rebuilt the tokenizer, pushed the vision system to a significantly higher resolution, and trained the model to be more rigorous, more honest, and more persistent on long tasks.

What is New in Claude Opus 4.7

Here are the changes that matter most for anyone actively building with Claude.

1. State-of-the-Art Software Engineering

Opus 4.7 is Anthropic's strongest coding model to date. It is designed to handle the hardest, most ambiguous engineering work - the kind that previously required you to sit next to the model and supervise.

Early partners shared real numbers:

• Cursor: CursorBench score jumped from 58% (Opus 4.6) to over 70% with Opus 4.7
• Rakuten-SWE-Bench: Opus 4.7 resolved 3x more production tasks than Opus 4.6, with double-digit gains in both code quality and test quality
• GitHub: +13% resolution on a 93-task coding benchmark, solving four tasks that neither Opus 4.6 nor Sonnet 4.6 could crack
• Qodo: Catches race conditions and real issues that previous Claude models missed
• CodeRabbit: +10% recall on code review without hurting precision

The pattern across partners is consistent: Opus 4.7 plans more carefully before acting, catches its own logical faults during the planning phase, and verifies its work before reporting back.

2. Long-Horizon Agent Reliability

This is arguably the biggest practical upgrade. Modern AI agents fail not because individual steps are hard, but because something eventually breaks over dozens or hundreds of steps - a looping tool call, a flaky API, a lost piece of context.

Opus 4.7 was trained to push through that kind of failure.

• Notion Agent reported a +14% lift on complex multi-step workflows at fewer tokens, with one third the tool errors of Opus 4.6 - and it keeps executing through tool failures that used to stop Opus cold.
• Genspark highlighted loop resistance, lower variance, and the "highest quality-per-tool-call ratio" they have measured.
• Devin reported that Opus 4.7 works coherently for hours on long-horizon investigations.

Combined with the full 1M token context window at standard pricing, Opus 4.7 is genuinely usable for the kind of async, multi-hour agent work that was painful to run on earlier models.

3. Dramatically Better Vision

Opus 4.7 accepts images up to 2,576 pixels on the long edge (~3.75 megapixels) - more than 3x the resolution of prior Claude models. This is a model-level change, so every image you send is processed at higher fidelity automatically.

Practical consequences:

• Computer-use agents can read dense screenshots and small UI text reliably
• Technical diagrams, chemical structures, and engineering schematics are readable without pre-processing
• Document extraction from messy PDFs and scans is sharper

XBOW, who builds autonomous penetration testing tooling, measured 98.5% on their visual-acuity benchmark, up from 54.5% on Opus 4.6. That is not an incremental improvement - it unlocks whole new categories of computer-use work.

4. Sharper Instruction Following and Honesty

Anthropic explicitly flags that Opus 4.7 follows instructions more literally than previous models. This is a double-edged sword: prompts that worked before may now produce unexpected results because earlier models skipped parts of your instructions. If you are migrating, plan to re-tune your prompts and harnesses.

Opus 4.7 is also more honest about what it does and does not know. Hex noted that it "correctly reports when data is missing instead of providing plausible-but-incorrect fallbacks" and resists dissonant-data traps that fooled Opus 4.6. Replit called it out for pushing back during technical discussions rather than reflexively agreeing with the user.

For production systems, that kind of calibration is often worth more than raw capability.

5. Improved Memory and Long-Session Work

Opus 4.7 is noticeably better at using file-system-based memory. It remembers important notes across long, multi-session work, and uses them when starting new tasks. That means less up-front context to replay at the start of every session - a win for both latency and bill.

6. New xhigh Effort Level

Anthropic introduced a new xhigh ("extra high") effort level, sitting between high and max. Why bother with another tier? Because on hard problems, high was sometimes not enough and max was wasteful. xhigh gives you a finer knob for trading off reasoning depth vs. latency.

For coding and agentic use cases, Anthropic explicitly recommends starting with high or xhigh. In Claude Code, the default has been raised to xhigh for all plans.

7. Task Budgets (Public Beta)

Alongside the model, Anthropic launched task budgets in public beta. You can now give Claude a token budget for a task and let it prioritize work across longer runs, which is especially helpful when running autonomous agents overnight or at scale.

Claude Opus 4.7 Pricing

Opus 4.7 is priced identically to Opus 4.6:

Category	Price
Base input tokens	$5 / MTok
5-minute cache writes	$6.25 / MTok
1-hour cache writes	$10 / MTok
Cache hits and refreshes	$0.50 / MTok
Output tokens	$25 / MTok
Batch input	$2.50 / MTok
Batch output	$12.50 / MTok

A few important details:

• 1M token context window is included at standard pricing. A 900K-token request is billed at the same per-token rate as a 9K-token request.
• Prompt caching still applies: cache reads cost just 10% of the base input price, so heavy-context agents can get meaningfully cheaper with a little planning.
• Batch API still gives a 50% discount on both input and output, which stacks well with caching for high-volume workloads.

The Tokenizer Caveat

Opus 4.7 ships with a new tokenizer that contributes to its improved performance. The tradeoff is that the same input can map to up to ~35% more tokens depending on the content type. Anthropic also notes that Opus 4.7 "thinks more" at higher effort levels, which means more output tokens on hard problems.

In Anthropic's own internal coding evaluation, the net effect is favorable - score per dollar still improves - but you should measure this on your own traffic before declaring a win. If token usage is a concern, you can:

• Drop down to a lower effort level for simpler tasks
• Use task budgets to cap spend
• Prompt the model to be more concise
• Lean harder on prompt caching and batching

Claude Opus 4.7 vs the Rest of the Claude Family

Here is how Opus 4.7 stacks up against the other production Claude models.

Feature	Claude Opus 4.7	Claude Opus 4.6	Claude 4.6 Sonnet	Claude Haiku 4.5
Released	April 2026	Early 2026	Early 2026	Late 2025
Context Window	1M tokens	1M tokens	1M tokens (beta)	200K tokens
Input Pricing	$5 / MTok	$5 / MTok	$3 / MTok	$1 / MTok
Output Pricing	$25 / MTok	$25 / MTok	$15 / MTok	$5 / MTok
Best For	Frontier coding, agents	Strong coding	Balanced daily driver	High-volume, low-cost
Vision	Up to 3.75 MP	Standard	Standard	Standard
Agent Work	Best-in-class	Very strong	Strong	Limited

When to use Opus 4.7

• Hardest software engineering work - architecture decisions, hairy refactors, concurrency bugs, large PR reviews.
• Long-running autonomous agents - multi-hour investigations, CI/CD automations, research agents, computer-use tasks.
• High-resolution vision - computer-use, diagram extraction, UI screenshots, life-sciences imagery.
• High-stakes professional work - legal review, financial analysis, dashboards, complex document reasoning.

When a cheaper model is the right call

• High-volume, simple tasks (summaries, classification, extraction, chat) - Haiku 4.5 is 5x cheaper on input and 5x cheaper on output.
• Balanced day-to-day coding and writing - Sonnet 4.6 is a strong, cheaper default that early-access developers sometimes preferred to Opus 4.5 for practical work.
• Extreme cost sensitivity at scale - combine Sonnet or Haiku with prompt caching and batch processing.

A healthy stack often routes easy requests to Haiku or Sonnet and escalates only the hardest work to Opus 4.7. This is exactly the kind of pattern where task budgets and effort controls help you keep spend predictable.

Claude Opus 4.7 vs GPT-5.4 and Gemini 3.1 Pro

Anthropic benchmarked Opus 4.7 against the best publicly available versions of GPT-5.4 and Gemini 3.1 Pro and reports leading or competitive results across coding, vision, document reasoning, long-context reasoning, and agent evaluations. Some early-access data points from partners:

• CodeRabbit: "A bit faster than GPT-5.4 xhigh" on their review harness.
• Harvey: 90.9% on BigLaw Bench at high effort, with strong calibration on ambiguous edits.
• Databricks OfficeQA Pro: 21% fewer errors than Opus 4.6 on enterprise document reasoning.

Migrating From Opus 4.6 to Opus 4.7

Anthropic calls Opus 4.7 a "direct upgrade" to Opus 4.6, but two things are worth planning for:

1. Tokenizer changes. The new tokenizer can produce up to ~35% more tokens for the same text. Measure this on your real traffic before assuming flat cost.

2. Stricter instruction following. Prompts written for Opus 4.6 (or earlier) sometimes break because Opus 4.7 takes every instruction literally. If you had optional-but-implied behavior baked into your system prompts, make it explicit - or remove conflicting instructions the older models politely ignored.

Practical migration checklist:

1. Swap claude-opus-4-6 for claude-opus-4-7 in a staging environment first.
2. Start with high effort; escalate to xhigh on hard problems; only reach for max when you truly need it.
3. Re-evaluate your prompts - especially long system prompts and agent harnesses - for conflicting or ambiguous instructions.
4. Turn on task budgets if you run long autonomous jobs.
5. Measure token usage, latency, and quality on a representative sample of production traffic before flipping the switch globally.

Safety and Alignment

Opus 4.7's safety profile is broadly similar to Opus 4.6. Anthropic's evaluations show low rates of concerning behaviors like deception, sycophancy, and cooperation with misuse. On honesty and prompt-injection resistance, Opus 4.7 is an improvement on Opus 4.6. Anthropic's alignment assessment describes the model as "largely well-aligned and trustworthy, though not fully ideal in its behavior."

For cybersecurity use, Opus 4.7 is shipped with automatic safeguards that detect and block prohibited or high-risk requests. Anthropic deliberately reduced its cyber capabilities during training - Mythos Preview remains more capable in that domain, but is kept under tighter release control. Security professionals doing legitimate work (vulnerability research, penetration testing, red-teaming) can apply to Anthropic's new Cyber Verification Program.

Who Should Care About Opus 4.7

Claude Opus 4.7 is the obvious default if you fall into any of these buckets:

• Engineering teams running AI-assisted coding, code review, or long-running migrations.
• Agent builders shipping multi-step, multi-tool autonomous workflows.
• Enterprise teams doing serious document reasoning - legal, finance, life sciences, consulting.
• Computer-use and RPA teams that need reliable vision on dense, real-world screenshots.
• Design-forward product teams building dashboards and data-rich interfaces, where Opus 4.7's taste and reliability save iteration time.

If your workload is mostly short, simple, high-volume requests, the jump from Sonnet 4.6 or Haiku 4.5 to Opus 4.7 may not be worth 5x the output cost - route selectively.
