Both are Anthropic models. Claude Sonnet 5 is the newer, generally stronger default; reach for Claude Opus 4.7 when a specific cost or latency profile matters more than the latest capabilities.
Claude Opus 4.7 and Claude Sonnet 5 are both Anthropic models, so the real question is not which lab to trust but which tier fits your workload and budget. Claude Opus 4.7 is the agentic-coding-focused Opus that traded some long-context recall for long-run reliability. Claude Sonnet 5 is anthropic's most agentic Sonnet, with near-Opus-4.8 performance at Sonnet prices; the default model on Free and Pro. Since both come from the same lab, the comparison below focuses on the tier-and-cost trade-offs that actually separate them.
Key differences
Price: Claude Sonnet 5 is about 1.7× cheaper on input ($3/$15 per 1M tokens vs $5/$25 per 1M tokens) — modest, but it adds up at steady volume.
Context window: both advertise 1M (~1,500 pages). Tie on paper — test on your own long inputs, since usable recall varies by model.
Recency: Claude Sonnet 5 is the newer model by about 3 months (released June 30, 2026), usually meaning fresher training data and capabilities.

Who wins what
Long-running agentic coding workflows: Claude Opus 4.7 — A core design strength of Claude Opus 4.7.
Precise instruction following: Claude Opus 4.7 — A core design strength of Claude Opus 4.7.
Task budgets and effort tiers: Claude Opus 4.7 — A core design strength of Claude Opus 4.7.
Agentic workflows that plan, use tools, and run autonomously: Claude Sonnet 5 — A core design strength of Claude Sonnet 5.
Multi-step coding, debugging, and tool use: Claude Sonnet 5 — A core design strength of Claude Sonnet 5.
Everyday professional and knowledge work: Claude Sonnet 5 — A core design strength of Claude Sonnet 5.
Lowest cost at scale: Claude Sonnet 5 — At $3/$15 per 1M tokens, it is the cheaper of the two — the gap dominates the bill on high-volume workloads.
Which should you pick?
A cost-sensitive startup shipping high volume: Claude Sonnet 5 — At $3/$15 per 1M tokens it undercuts Claude Opus 4.7, and on millions of tokens that margin decides the monthly bill.
Anyone whose priority is long-running agentic coding workflows: Claude Opus 4.7 — It is specifically built for that.
Anyone whose priority is agentic workflows that plan, use tools, and run autonomously: Claude Sonnet 5 — That is its strongest area.
Claude Opus 4.7: where it fits
The agentic-coding-focused Opus that traded some long-context recall for long-run reliability. Released April 16, 2026 by Anthropic, it is built for long-running agentic coding workflows, precise instruction following, task budgets and effort tiers, and large-codebase operation.
Its trade-offs are real: long-context recall regressed vs 4.6, and superseded by Opus 4.8. At $5 in / $25 out per million tokens, it sits in the premium price band.
Claude Sonnet 5: where it fits
Anthropic's most agentic Sonnet, with near-Opus-4.8 performance at Sonnet prices; the default model on Free and Pro. Released June 30, 2026 by Anthropic, it is built for agentic workflows that plan, use tools, and run autonomously, multi-step coding, debugging, and tool use, everyday professional and knowledge work, and long-document analysis and reasoning.
Its trade-offs: lower peak accuracy than Opus 4.8 on the hardest tasks, and an updated tokenizer that can use 1.0-1.35x more tokens for the same text. At $3 in / $15 out per million tokens, it sits in the mid price band.
The bottom line for this matchup
Because Claude Opus 4.7 and Claude Sonnet 5 come from the same lab (Anthropic), they share the same training philosophy and ecosystem — the decision is purely tier vs. cost. Claude Sonnet 5 is the more capable, more recent option; the other earns its place only when its price or latency profile fits a specific job better. Most teams should default to Claude Sonnet 5 and drop down only with a concrete reason.
Frequently asked questions
Is Claude Opus 4.7 or Claude Sonnet 5 better for coding?
Public SWE-Bench figures are not available for Claude Sonnet 5, so the honest test is your own repository — run an identical real bug through both. By design, Claude Opus 4.7 leans toward long-running agentic coding workflows while Claude Sonnet 5 leans toward agentic workflows that plan, use tools, and run autonomously, and that positioning usually predicts which feels better on your codebase.
Which is cheaper, Claude Opus 4.7 or Claude Sonnet 5?
Claude Sonnet 5 is cheaper — $5/$25 per 1M tokens vs $3/$15 per 1M tokens, roughly 1.7× apart on input.
Which has the bigger context window?
Both advertise 1M (~1,500 pages). Remember advertised ≠ usable: recall typically degrades before the ceiling.
Should I upgrade from Claude Opus 4.7 to Claude Sonnet 5?
Since both are Anthropic models, the newer one (Claude Sonnet 5) is usually the better default unless you need a specific cost or latency profile from the other.
Which is newer, Claude Opus 4.7 or Claude Sonnet 5?
Claude Sonnet 5 — released June 30, 2026, about 3 months after Claude Opus 4.7.
