On April 16, 2026, Anthropic released Claude Opus 4.7 — its most capable generally available model to date. The numbers tell the story: 64.3% on SWE-bench Pro (up from 53.4%), 70% on CursorBench (up from 58%), and a vision accuracy leap from 54.5% to 98.5%. All at the same $5/$25 per million token pricing as Opus 4.6.

This isn't a paradigm shift — it's a meaningful upgrade across every dimension that matters to developers: better coding, better agentic reasoning, 3x higher image resolution, stricter instruction-following, and a new xhigh effort level that gives you finer control over the quality/cost tradeoff. Anthropic is now running at a $30 billion annualized revenue rate, and Opus 4.7 is the model that has to justify those numbers.

This guide covers everything you need to know: benchmarks, new features, API breaking changes, migration from 4.6, vision capabilities, the competitive landscape against GPT-5.4 and Gemini 3.1 Pro, and how to get the most out of the model in production.

1What Changed in Opus 4.7

Opus 4.7 is a direct upgrade to Opus 4.6, continuing Anthropic's roughly two-month release cadence (Opus 4.5 in November 2025, Opus 4.6 in February 2026, Opus 4.7 in April 2026). It's not a new model tier — it's the same Opus class with targeted improvements in five areas:

Anthropic's internal teams use Claude Code daily, and each model release reflects what they learned from the previous one. Intuit describes Opus 4.7 as "catching its own logical faults during the planning phase and accelerating execution." Vercel's team observed it "doing proofs on systems code before starting work, which is new behavior."

2Benchmark Results: Coding, Vision & Agentic Tasks

Opus 4.7 posted gains across coding, vision, legal, finance, and agentic evaluations. Here are the headline numbers:

The CursorBench jump from 58% to 70% is particularly significant — it measures real-world coding assistance quality in the editor most developers actually use. Rakuten reported 3x more production tasks resolved compared to Opus 4.6, with double-digit gains in Code Quality and Test Quality scores. CodeRabbit saw recall improve over 10%, noting the model is "a bit faster than GPT-5.4 xhigh."

On Terminal-Bench 2.0, Opus 4.7 solved three tasks that no previous Claude model (or competing frontier model) could handle, including fixing a race condition that required multi-file reasoning across a complex codebase.

3High-Resolution Vision: 3.75 Megapixels

Previous Claude models were limited to roughly 1,568 pixels on the long edge (about 1.15 megapixels). Opus 4.7 raises that ceiling to 2,576 pixels — roughly 3.75 megapixels, more than 3x the visual capacity. No API parameter changes needed.

What this means in practice:

• Code screenshots at full resolution — no more squinting artifacts or misread variable names
• Technical diagrams with fine labels and small text rendered accurately
• Chemical structures and scientific notation parsed correctly (confirmed by Solve Intelligence)
• Charts and graphs with dense data points interpreted without hallucinating values
• Computer use coordinates now map 1:1 with actual pixels, eliminating the scale-factor math previously required

4The New xhigh Effort Level & Task Budgets

Opus 4.7 adds xhigh, a new effort level that sits between high and max. The effort scale now has five levels:

Claude Code defaults to xhigh for all plans. Hex's CTO noted that "low-effort Opus 4.7 is roughly equivalent to medium-effort Opus 4.6" — meaning the entire capability curve has shifted upward.

Task Budgets (Public Beta)

Task budgets are a new feature that gives the model a rough token target for an entire agentic loop (thinking, tool calls, tool results, and final output). The model sees a running countdown and uses it to prioritize work and wrap up gracefully as the budget runs out.

• Task budgets are advisory, not hard caps — distinct from max_tokens, which is a hard per-request ceiling the model isn't aware of
• Minimum task budget is 20,000 tokens
• For open-ended agentic tasks where quality matters more than speed, Anthropic recommends not setting a task budget

import anthropic

client = anthropic.Anthropic()

response = client.messages.create(
    model="claude-opus-4-7",
    max_tokens=16384,
    thinking={
        "type": "adaptive"
    },
    effort="xhigh",
    task_budget=50000,  # advisory token target
    messages=[{
        "role": "user",
        "content": "Refactor the auth module..."
    }]
)

5API Breaking Changes & Migration Guide

Opus 4.7 introduces three breaking changes to the Messages API. If you use Claude Managed Agents, there are no breaking API changes.

Migration Checklist

# Step 1: Update model name
model = "claude-opus-4-6"  # Before
model = "claude-opus-4-7"  # After

# Step 2: Switch to adaptive thinking
thinking = {"type": "enabled", "budget_tokens": 8192}  # Before (400 error)
thinking = {"type": "adaptive"}  # After

# Step 3: Remove sampling parameters
temperature = 0.7  # Before (400 error)
# Just omit it — use prompting instead

# Step 4: Opt in to thinking display (if needed)
# Add to request: "display": "summarized"

# Step 5: Update max_tokens for headroom
# The new tokenizer may produce 1.0-1.35x more tokens
max_tokens = 8192   # Before
max_tokens = 12000  # After (give headroom)

6Opus 4.7 vs GPT-5.4 vs Gemini 3.1 Pro

The frontier model landscape as of April 2026 is tighter than ever. Here's how Opus 4.7 stacks up against the competition:

The takeaway: Opus 4.7 leads convincingly on coding benchmarks — the tasks most directly tied to real-world developer productivity. On graduate-level reasoning (GPQA Diamond), all three models have converged around 94%, effectively saturating the benchmark. The competitive differentiation has shifted from raw reasoning to applied performance on complex, multi-step tasks.

Gemini 3.1 Pro undercuts both Opus 4.7 and GPT-5.4 at $2/$12 per million tokens and offers a 2M token context window. For cost-sensitive workloads where coding performance isn't the primary concern, it's a strong choice. But for enterprise teams whose workloads demand the highest coding capability, Opus 4.7's lead on SWE-bench justifies the premium.

GPT-5.4 leads on computer use (75% OSWorld, first to beat humans) and professional knowledge work (83% GDPval). If your primary use case is desktop automation or broad knowledge tasks, GPT-5.4 may be the better fit. For coding and agentic workflows, Opus 4.7 is the current leader.

7Self-Verification & Instruction-Following

Two behavioral changes in Opus 4.7 deserve special attention because they affect how you write prompts and what you can expect from the model.

Self-Verification

Opus 4.7 proactively verifies its own outputs before reporting them. This isn't just "chain of thought" — the model checks its work against the original requirements, catches logical faults during planning, and validates that its output actually solves the stated problem. Vercel's team observed it doing "proofs on systems code before starting work," which is genuinely new behavior.

In practice, this means fewer rounds of "wait, let me check that" from the user. The model catches more of its own mistakes before you see them.

Stricter Instruction-Following

This is a double-edged upgrade. Opus 4.7 interprets instructions more literally than 4.6. If your prompt says "fix the login function," it will fix the login function — it won't also refactor the adjacent auth middleware unless you ask. Notion found it was the first model to pass their "implicit-need tests" — tasks where the model must infer what tools or actions are required rather than being told explicitly.

8Cybersecurity Safeguards & Project Glasswing

Opus 4.7 includes automated safeguards that detect and block requests indicating prohibited or high-risk cybersecurity uses. These safeguards are part of Anthropic's broader Project Glasswing initiative and serve as a testing ground for eventual broader release of their more capable Mythos-class models.

The cyber capabilities in Opus 4.7 are intentionally less advanced than what Anthropic's internal Mythos Preview can do. Training included differential reduction of certain cyber capabilities as a safety measure.

Legitimate security professionals can access cybersecurity capabilities through Anthropic's new Cyber Verification Program. This covers vulnerability research, penetration testing, and red-teaming.

Opus 4.7 maintains a similar safety profile to Opus 4.6 with targeted improvements in honesty and resistance to prompt injection attacks. Anthropic's assessment describes it as "largely well-aligned and trustworthy, though not fully ideal."

9Pricing, Availability & Claude Model Lineup

No price increase. Opus 4.7 maintains the same pricing as Opus 4.6:

Full Claude Model Lineup (April 2026)

Opus 4.7 is available across:

• Claude Pro, Max, Team, and Enterprise subscriptions
• Claude API as claude-opus-4-7
• Amazon Bedrock
• Google Cloud Vertex AI
• Microsoft Foundry

The 1M token context window is included at standard pricing with no long-context premium. Maximum output is 128K tokens. The tokenizer change means the same input may cost slightly more (1.0-1.35x) due to different token boundaries, but for most workloads the increase is negligible.

10When to Use Opus 4.7 vs Sonnet 4.6

The Opus/Sonnet split still makes sense. Sonnet 4.6 at $3/$15 handles daily coding tasks, quick questions, and moderate-complexity work extremely well. Opus 4.7 at $5/$25 is for the heavy lifting:

For teams using AI coding agents like Cursor, Claude Code, or Kiro, the upgrade path is straightforward: switch your default Opus model to 4.7. The only adjustment needed is reviewing prompts that depended on loose instruction interpretation.

Anthropic also shipped a new /ultrareview slash command in Claude Code that runs a focused review session, flagging bugs and design issues. Pro and Max users get 3 free ultrareviews. And Auto mode is now available for Max users, letting Claude make decisions autonomously with fewer interruptions.

For multi-model routing strategies, consider pairing Opus 4.7 for complex tasks with Sonnet 4.6 for routine work and Haiku 4.5 for high-volume, low-complexity requests. This approach optimizes both cost and quality across your AI workloads.

If you're building multi-agent systems with Claude Code, Opus 4.7's improved multi-agent coordination and longer autonomous sessions make it the clear choice for orchestrator agents, while Sonnet 4.6 can handle individual worker agents cost-effectively.
