Why each one is on the shortlist for Claude Opus 5 vs Claude Fable 5, what it is genuinely good at, and where we would steer you away from it.
Our pick for Claude Opus 5 vs Claude Fable 5. It scores 100/100 on the coding axis we weight this page by, and nothing else in this shortlist matches it on output quality.
Anthropic's flagship-tier Opus that comes close to Claude Fable 5's frontier intelligence at half the price — the new default for complex agentic coding and enterprise agents.
You need fast interactive latency (Sonnet 5 is quicker and one-fifth the price) or absolute frontier ceiling (Fable 5).
The new premium coding default. Opus 5 takes the SWE-bench Verified lead from Opus 4.8 at the same $5/$25 price, and gets within half a point of Fable 5 on agentic coding at half the cost. Choose Fable 5 only when absolute frontier intelligence matters more than budget.

Here for latency: it answers fastest of anything listed for Claude Opus 5 vs Claude Fable 5, at 100/100 on coding.
Anthropic's new Mythos-class flagship and the most capable coding model anyone can use — 80.3% SWE-Bench Pro, an 11-point jump over Opus 4.8. 1M context, 128K output, native parallel subagents. Released June 9, 2026.
You are latency- or cost-sensitive, or your tasks don't need frontier-level reasoning — Opus 4.8 at half the price is plenty.
The strongest coding and reasoning model you can actually use today. 80.3% SWE-Bench Pro is an 11-point leap over Opus 4.8 — the biggest single-release jump of 2026. It costs 2× Opus 4.8, so use it for the hardest agentic and engineering work and keep Opus 4.8 or Sonnet for everyday volume.

Claude Opus 5 wins on more of the categories we score — coding, research, reasoning — so it is the better default of the two. Claude Fable 5 is the better pick when your work is mostly the hardest coding tasks and autonomous multi-step agents. Neither is universally "better": Claude Opus 5 is aimed at complex agentic coding and enterprise agent workflows, Claude Fable 5 at the hardest coding tasks and autonomous multi-step agents.
Claude Opus 5 is cheaper at $5/1M input and $25/1M output. Claude Fable 5 costs $10/1M input and $50/1M output.
Both Claude Opus 5 and Claude Fable 5 have the same 1M context window.
Claude Opus 5 and Claude Fable 5 are similarly matched on coding. GPT-6 Astra is the overall coding leader in this directory at 100/100.
Both Claude Opus 5 and Claude Fable 5 have similar speed profiles — rated deliberate. Neither will be the bottleneck if latency is your deciding factor.
Still short of Claude Fable 5's absolute frontier ceiling on the hardest long-running agent tasks. Fast mode (research preview) doubles pricing to $10/$50, erasing the cost advantage over Fable 5. Avoid it if you need fast interactive latency (Sonnet 5 is quicker and one-fifth the price) or absolute frontier ceiling (Fable 5). That is the main case for looking at Claude Fable 5 instead.
Priced at $10/$50 per 1M tokens — double Opus 4.8 ($5/$25). Deliberate pace; not for latency-sensitive interactive apps. Standard-use safeguards block some high-risk security workloads (use Mythos 5 with partner access). Avoid it if you are starting new work — Claude Fable 5.1 supersedes it at the same base price with 75% cheaper cache reads. Also skip it if you are latency- or cost-sensitive. Against Claude Opus 5 specifically, the two are close enough on capability that price and speed decide it.
Take a moderate workload of 10M input and 2M output tokens a month. Claude Opus 5 runs $100.00 (at $5/1M in and $25/1M out); Claude Fable 5 runs $200.00 (at $10/1M in and $50/1M out). That is a $100.00/month difference — Claude Opus 5 is the cheaper of the two at this volume, and the gap scales linearly as you send more. Output tokens dominate the bill on both, so prompt length matters far less than response length.
Yes, and for most teams that beats picking one. A common split is Claude Opus 5 for complex agentic coding and enterprise agent workflows, with Claude Fable 5 handling the hardest coding tasks and autonomous multi-step agents. Since Claude Opus 5 is both the stronger and the cheaper option here, a split mainly makes sense if Claude Fable 5 covers a capability you specifically need.
