Claude Opus 4.7 is Anthropic's most capable generally available model, released April 16, 2026 as the flagship of the Claude 4 family. Its headline is a step-change in agentic coding: SWE-bench Verified jumps to 87.6% (from 80.8% on Opus 4.6) and SWE-bench Pro to 64.3%, while it tops the LMArena coding leaderboard. For a buyer, the single sentence is this: if you are building long-horizon coding or computer-use agents and accuracy beats latency, Opus 4.7 is the default choice on Anthropic — at unchanged $5/$25 pricing.

What's new

  • Step-change in agentic coding: SWE-bench Verified 80.8% to 87.6%, SWE-bench Pro 53.4% to 64.3%, Terminal-Bench 2.0 65.4% to 69.4%, OSWorld-Verified 72.7% to 78.0%.
  • New tokenizer that can consume up to ~35% more tokens for identical text — a real cost-modeling change despite flat per-token pricing.
  • Vision pipeline accepts images roughly 3x larger than Opus 4.6 (2,576 px long edge), making PDF/slide/screenshot reasoning genuinely reliable; CharXiv with tools 84.7% to 91.0%.
  • New xhigh effort level and task budgets (beta) for finer control over thinking spend.
  • The model verifies its own outputs and follows instructions more literally; some prompts tuned for prior Opus generations may need updating.
  • State-of-the-art Finance Agent (64.4%) and strong cyber-defense eval (CyberGym 73.1%).
  • BrowseComp regressed slightly (83.7% on 4.6 to 79.3%), the one benchmark that did not improve.

AI Panel Review

Six personas, six verdicts — the same panel that reviews every product on TopReviewed.

Decision Maker9/10
Opus 4.7 is the safest frontier bet on Anthropic: flat price, real multi-cloud, and the agentic-coding lead that justifies the tier.

For a one-to-two-year platform bet, Opus 4.7 is the lowest-risk Anthropic landing pad. Pricing held at $5/$25, it is GA across Anthropic, Bedrock, Vertex, and Foundry, and the coding lead is defensible against GPT-5.5 and Gemini 3.1. The structural risk is lock-in: prompts tuned to Opus 4.7's literal instruction-following and new tokenizer do not port one-to-one to other vendors, and the tokenizer change resets cost models. Roadmap confidence is high given Anthropic's cadence. For frontier coding agents this is the default; chat surfaces should tier down to Sonnet or Haiku.

Strategic Fit 9Vendor Risk 7Roadmap Confidence 9
Pros
  • Frontier coding, flat price, multi-cloud failover, mature governance
Cons
  • Lock-in via tokenizer/prompt tuning
  • slow latency
Right for: orgs standardizing serious agentic workloads on Anthropic
Avoid if: you need vendor-neutral portability or sub-second UX
Domain Strategist9/10
Anthropic owns the agentic-coding narrative, and Opus 4.7 is the proof point that keeps Cursor, Windsurf, and Copilot in the fold.

In market terms, Opus 4.7 cements Anthropic's moat in code and agents — the segment with the stickiest enterprise spend and the clearest ROI story. Topping the LMArena coding board and SWE-bench while holding price is a positioning win that competitors must answer on capability, not discounting. The differentiation is narrowing on raw intelligence (GPT-5.5 leads the AA Index at 60 vs 57), so Anthropic's edge is increasingly "best at doing work," not "highest IQ." Market timing is strong: launched into a cycle where agentic coding is the dominant enterprise use case.

Competitive Positioning 9Differentiation 8Market Timing 10
Pros
  • Clear category leadership in coding/agents
  • ecosystem gravity
Cons
  • Intelligence-index lead ceded to GPT-5.5
  • browse regressed
Right for: teams betting on the agentic-coding wave
Avoid if: your wedge is raw reasoning or real-time data
Finance Lead8/10
Headline price is unchanged, but the new tokenizer is a stealth 35% line-item increase you must model before you commit.

At $5/$25 the rate card matches Opus 4.6 and 4.5, and cache reads ($0.50) plus batch ($2.50/$12.50) cut stable-workload bills sharply. The trap is the tokenizer: identical text can bill up to 35% more tokens, so per-task TCO rises even though per-token price did not. The 1M context at flat pricing is a genuine win — no long-context premium. Fast Mode at 6x must be ring-fenced to UX-critical calls. Value-per-dollar is good for hard work, mediocre for routine work that Sonnet or Haiku would handle at a fraction of the cost.

Cost Efficiency 7Pricing Transparency 8Value per Dollar 7
Pros
  • Flat rate card, deep cache/batch discounts, flat 1M-context pricing
Cons
  • Tokenizer inflates effective cost
  • overkill for simple tasks
Right for: high-value agentic jobs with good caching
Avoid if: budget-sensitive high-volume traffic
Domain Practitioner9.5/10
The SDK is unchanged, tool use just works, and the diffs are cleaner — Opus 4.7 closes real PRs, not toy issues.

For a hands-on builder, Opus 4.7 is the smoothest agent target Anthropic ships. The bash, text-editor, and computer-use scaffolds from Opus 4.6 keep working; streaming, structured output, and prompt caching behave identically. SWE-bench Verified 87.6% and SWE-bench Pro 64.3% translate to noticeably fewer "almost right" diffs in real workflows, and the xhigh effort level and task budgets give finer control over thinking cost. The one sharp edge is the tokenizer: cost estimators and context budgeters built for 4.6 silently under-count. Docs are excellent and the Claude Agent SDK is first-class.

API Ergonomics 9Tool/Agent Support 10Reliability 9
Pros
  • Stable API surface, best-in-class agent tooling, fewer broken diffs
Cons
  • Tokenizer breaks old budgets
  • latency hurts tight loops
Right for: developers shipping autonomous coding agents
Avoid if: you need fast, cheap, simple completions
Power User8.5/10
Conversation quality is excellent and refusals are rare, but you feel every second of the thinking latency.

For a heavy daily user, Opus 4.7 is the most capable conversational Claude — concise when asked, coherent across very long sessions, and far less prone to over-refusal than 2024-era Claude. Vision genuinely works on pasted screenshots and PDFs. The trade-off is speed: time-to-first-token in max-effort mode is long and output streams at ~55 t/s, so it feels deliberate, not snappy. For deep work that is fine; for rapid back-and-forth it is frustrating, and most users will keep Sonnet 4.6 for everyday chat and reach for Opus 4.7 on hard problems.

Output Quality 9.5Speed 6Everyday Usefulness 8.5
Pros
  • Top-tier answers, low refusal, strong vision
Cons
  • Slow first token
  • verbose by default
Right for: power users on hard, high-stakes tasks
Avoid if: you want instant, lightweight replies
Skeptic7.5/10
A frontier coder that GPT-5.5 out-thinks on the index, slowed to a crawl, with a tokenizer that quietly raises your bill 35%.

The agentic-coding numbers are real and independently corroborated, so the headline holds. But three claims deserve scrutiny. First, "most capable" is selective: GPT-5.5 xhigh leads the Artificial Analysis Index 60 to 57, and Gemini 3.1 Pro ties at 57 — Opus 4.7's lead is in coding and agents, not general intelligence. Second, the "unchanged pricing" framing hides a real ~35% effective cost increase from the new tokenizer. Third, BrowseComp regressed, and the absence of clean AIME/MMLU-Pro disclosures makes the reasoning story partly unverifiable. SWE-bench is also the most prompt-sensitive, scaffold-sensitive benchmark in the suite — gains there are partly engineering, not pure model. It is excellent at code; treat the "frontier everything" gloss with caution.

Claim Accuracy 7.5Weakness Severity 6.5Hype vs Reality 7
Pros
  • Coding leadership is genuine
  • governance is real
Cons
  • Not the smartest by index
  • slow
  • stealth cost rise
  • one benchmark regressed
Right for: skeptics who need verifiable coding wins
Avoid if: you take "most capable model" at face value

Strengths

  • Best-in-class agentic coding on real-world SWE-bench tasks; sustains multi-hour engineering work with limited human-in-the-loop.
  • 1M-token context at standard pricing — whole-monorepo or whole-trial-transcript prompts are cost-competitive.
  • High-resolution vision unlocks reliable PDF/slide/screenshot reasoning without external OCR.
  • More literal, self-verifying instruction following reduces "creative interpretation" failures.
  • Near-frontier scientific reasoning (GPQA Diamond 94.2%) and SOTA Finance Agent.

Limitations

  • New tokenizer means Opus-4.6 cost and context budgets silently under-count by up to ~35%.
  • High time-to-first-token and ~55 t/s output make it the slowest-feeling current Claude; poor for snappy chat.
  • BrowseComp regressed vs 4.6 (79.3% vs 83.7%) — heavy browse-and-synthesize pipelines may not see uniform uplift.
  • No explicit extended-thinking toggle; effort levels are a different mental model for some teams.
  • No clean published AIME 2025 / MMLU-Pro figure, so a couple of standard reasoning columns are null.

Best use cases

  • Long-horizon coding agents (multi-file refactors, autonomous PR loops, end-to-end feature builds in Claude Code).
  • Computer-use and browser-control agents where each step is expensive and accuracy outweighs throughput.
  • Heavy-document workflows (legal review, financial analysis, scientific literature) where 1M context plus high-res vision are real differentiators.
  • Hard reasoning where extra thinking budget actually moves the answer (GPQA-Diamond-difficulty research synthesis).

Architecture

Anthropic does not disclose parameter count, layer count, attention mechanism, or architecture family for any Claude model, so total_params, active_params, attention_type, and architecture_type are honestly null/unknown. What is disclosed: Opus 4.7 introduced a new tokenizer (distinct from prior Claude generations) that contributes to capability gains but expands token counts by up to ~35% on fixed text; a 1M-token context window served at standard pricing; and 128k synchronous max output (300k via batch beta). Reasoning is delivered through Anthropic's adaptive-thinking system with effort levels (now including xhigh) rather than the explicit extended-thinking toggle exposed on Sonnet 4.6 and Haiku 4.5.

Capabilities

Coding (9.8): the strongest agentic coder in the Claude line — SWE-bench Verified 87.6%, SWE-bench Pro 64.3%, LMArena coding Elo 1554 (highest of any Claude). Reasoning (9.5): GPQA Diamond 94.2%, HLE with tools 54.7%, Artificial Analysis Index 57 (third overall). Math (9.0): inferred from the GPQA/HLE tier and frontier AIME-class performance; Anthropic did not publish a clean AIME 2025 figure for 4.7, so the math score is anchored to adjacent reasoning evals rather than a single benchmark. Agentic/tool use (9.8): Terminal-Bench 2.0 69.4%, OSWorld-Verified 78.0%, MCP-Atlas 77.3%, plus the full first-party tool suite (bash, text editor, computer use, web search, web fetch, code execution). Long-context (9.3): 1M tokens at standard pricing; degrades gracefully but not perfectly across the full window. Multilingual (9.0): MMMLU 91.5%. Vision (9.0) and document/OCR (9.0): the 3x resolution bump makes native document reasoning dependable; CharXiv with tools 91.0%. Instruction-following (9.5): the most literal and self-verifying Claude yet. Function-calling (9.5): robust parallel tool calls and structured output. Safety calibration (9.3): ASL-3 deployment, low over-refusal. Realtime-data (7.0): no native knowledge of post-January-2026 events, but first-party web search and web fetch close the gap when enabled.

Speed & latency

Output speed is ~54.6 tokens/sec on Anthropic's API (Artificial Analysis), below the reasoning-tier median (~72 t/s), and time-to-first-token in adaptive max-effort mode is high — ~23.85s — because the model thinks extensively before emitting tokens. This places it in the slow latency tier for interactive chat. It is not the model for sub-second turn-taking; it is the model for jobs where a few extra seconds of latency buys a materially better answer. Fast Mode (beta, 6x price) trades cost for speed when low latency is mandatory. In batch use, latency is irrelevant and the 50% discount applies.

Deployment & access

Proprietary, no open weights, no self-hosting. Available first-party via the Claude API and Claude Platform on AWS, plus Amazon Bedrock (global and regional endpoints), Google Vertex AI (global, multi-region, regional), and Microsoft Foundry. Regional/multi-region endpoints carry a 10% premium; first-party US-only routing via inference_geo: "us" adds a 1.1x multiplier. Data residency options include US and global routing. This is genuine multi-cloud availability, which matters for failover and procurement.

Safety & privacy

Governed by Anthropic's Responsible Scaling Policy v3.0 (effective 2026-02-24) and deployed under ASL-3 protections (CBRN-focused deployment and security standards, activated with the Opus 4 generation). Anthropic does not train on API inputs by default; opt-out and zero-retention options exist for eligible accounts. Compliance: SOC 2 Type II, ISO 27001:2022, ISO/IEC 42001:2023 (AI management), HIPAA (BAA available), and GDPR. No built-in content-moderation classifier is forced on API output; safety is model-internal with mature refusal calibration.

Ecosystem & tooling

SDKs in Python, TypeScript, Java, Go, Ruby, and C#. First-class support in the Claude Agent SDK and Claude Code, plus LangChain, LlamaIndex, Vercel AI SDK, and Pydantic AI. It powers or is selectable in Cursor, GitHub Copilot, Windsurf, CodeRabbit, and Replit. Popularity is dominant in the agentic-coding segment, where Anthropic holds the top LMArena coding slots.

Buyer questions

How much will the new tokenizer actually cost me?

Per-token price is unchanged at $5/$25, but identical text can tokenize up to ~35% larger. Re-run your cost model on representative prompts before committing volume.

Is it worth migrating from Opus 4.6?

For coding and agents, yes — the SWE-bench Pro and OSWorld gains are large. For chat or copy, the lift is marginal and 4.6 may cost less per task.

Can I run it without latency pain?

Use Batch API for non-interactive work (latency irrelevant, 50% off) or Fast Mode (6x price) for interactive needs; otherwise expect deliberate response times.

What about data security?

No training on API inputs by default; SOC 2 Type II, ISO 27001/42001, HIPAA BAA, and GDPR all covered. Zero-retention and US data residency are available.

Which clouds?

First-party Claude API plus Bedrock, Vertex AI, and Microsoft Foundry, with regional endpoints for data-residency needs.

How does it handle 1M-token prompts?

Served at standard per-token pricing with no long-context premium; caching and batch discounts apply across the full window.

Comparable models

GPT-5.5OpenAI

Leads the Artificial Analysis Intelligence Index (60 vs 57) and many reasoning evals; Opus 4.7 counters on SWE-bench and agentic coding leadership and on LMArena coding Elo.

Gemini 3.1 ProGoogle

Ties Opus 4.7 on the AA Index (57) and competes on long-context and multimodal; generally behind on SWE-bench Pro and agentic coding.

Claude Sonnet 4.6: Same family; ~8 pts behind on SWE-bench Verified (79.6%) at 60% of input cost and faster latency — the right default for everything that is not frontier-hard.
