The 60-second version

  • Claude Opus 5 is Anthropic’s new default Opus model — included in every paid plan and pitched as near-Fable-5 capability at about half the price, at the same $5/$25 per-token rate as Opus 4.8.
  • It’s state-of-the-art on Anthropic’s coding evals (43.3% on Frontier-Bench), and the standout new behavior is self-verification — it checks its work against a goal, fixes bugs at the root cause, and recovers from its own errors instead of one-shotting.
  • A low / medium / high effort dial is the cost lever: dropping from max to low cut one benchmark’s cost per task from ~$22 to ~$3.76, and creators found it often works better at medium than at max.
  • Skeptics push back — Every calls it “frustrating with flashes of brilliance,” Alex Finn flags three dealbreakers (verbose personality, tighter usage limits, a coding harness that lags Codex), and it can stop early on complex tasks.

The questions everyone’s Googling.

Straight answers, pulled from across all 10 breakdowns.

What is Claude Opus 5?

Claude Opus 5 is Anthropic’s new default Opus model, launched July 24, 2026 and included in every paid Claude plan (Pro, Max, Team, Enterprise) with no extra usage cap. It’s positioned as near-Fable-5 capability at roughly half the price, and it’s now the default model on Claude Max and the strongest model available to Claude Pro. Anthropic pitches it as state-of-the-art on its own coding evals while costing the same per token as the older Opus 4.8.

Opus 5 vs Fable 5 — which is better?

It’s close, and cost is the tiebreaker. Anthropic’s own charts put Opus 5 at or near Fable 5 on most benchmarks while costing about half as much per task. Creators split the live tests 1-1 to 2-1 on raw output quality — Naman and Alex Finn preferred Opus 5’s visual builds, while Fable 5 still led on a denser flight-sim city and on multidisciplinary reasoning, legal, and health tasks. The consensus: comparable power, but Opus 5 wins on price.

Opus 5 vs Opus 4.8 — what changed?

Same price ($5/$25 per million input/output tokens), much bigger model. Opus 5 more than doubles Opus 4.8 on Frontier-Bench software-engineering tasks (43.3% vs 21.1% in Nick Saraev’s reading), and jumps from 1.5% to 30.2% on ARC-AGI-3 novel problem-solving — a 20x leap in one generation. Chase AI calls the 4.8-to-5 jump a bigger leap than the gap between Opus 5 and Fable 5. The new behaviors are self-verification and error recovery: it checks its work against a goal and iterates instead of one-shotting.

How much does Opus 5 cost, and is it worth it?

$5 per million input tokens and $25 per million output tokens — unchanged from Opus 4.8 and about half of Fable 5’s rate. The important number is cost-per-task, not price-per-token: in a head-to-head 3D city simulation, Opus 5 finished for $4.20 versus Fable 5’s $9.60. Watch out for the price-per-token trap — Kimi K3 is cheaper per token but burned roughly twice the tokens to finish the same task, netting the same real cost. For near-frontier work at lower total cost, most creators judged it worth defaulting to.

What effort level should I use on Opus 5?

Medium is the sweet spot for most work; drop to low for simple tasks and only reach for high on the genuinely hard 20%. Chase AI found dropping from max to low effort cut cost per task from about $22 to $3.76 — over 80% — while low effort still hit a 60% pass rate on a long-horizon agentic benchmark. Every went further: Opus 5 actually performs better at medium or low than at high or max, so cranking the dial can cost you both money and quality.

Is Opus 5 good at coding?

Yes — it’s state-of-the-art on Anthropic’s agentic coding evals, leading Frontier-Bench at 43.3% and one-shotting playable game clones, a macOS clone, and 3D simulations in creator tests. Its real edge is cost-per-task and self-verification: fixing bugs at the root cause and building its own test harnesses. Caveats: Fable 5 and Kimi K3 still edge it on some front-end polish and cybersecurity work, and Every found it stops early on big, complex skill files. Codex users on GPT-5.6 saw little reason to switch.

Reach for OPUS 5 when…

  • As your new default for most day-to-day work — it’s included in every paid plan at full budget, where Fable 5 capped Alex Finn at 50% of his allowance.
  • Cost-sensitive near-frontier coding, where matching Fable 5’s output for roughly half the per-task cost is the whole point (Opus 5 $4.20 vs Fable 5 $9.60 on a 3D city sim).
  • Long-horizon agentic runs that need to self-verify — it built its own computer-vision pipeline and its own test harness to validate work with no live reference to check against.
  • Business-workflow automation, where it posted the widest single gap on AutomationBench (26.0% vs ~17-18% for rivals) and topped Zapier’s AutomationBench at every effort level.
  • Complex reasoning and engineering — WorldofAI ranked it the top reasoning model he tested and its one-shot game and simulation builds impressed across the corpus.
  • Debugging that needs a real fix — on a real open-source bug it found and fixed the root cause where a rival model only patched the surface symptom.

Reach for something else when…

  • The hardest frontier tasks and multidisciplinary reasoning, where Fable 5 still leads unless Opus 5 is allowed tool use — Anthropic itself reserves Fable 5 for planning, brainstorming, and the toughest bugs.
  • Advanced cybersecurity and vulnerability-finding, the one area creators and Anthropic agree Fable 5 (and the uncensored Mythos 5) still lead — Anthropic appears to have deliberately capped Opus 5’s exploit capability.
  • Legal and health work, where the same benchmarks show Opus 5 slipping behind Fable 5 (legal reasoning dropped 13.3% to 11.7%).
  • Front-end polish and physics out of the box — WorldofAI still reaches for the cheaper Kimi K3 for UI-heavy web builds, and Fable 5’s flight-sim city was denser with working sound.
  • Big, complex legacy skill stacks — Every found Opus 5 gets worse as skill-file complexity rises and stops early; simpler prompts and fresh starts work better.
  • Daily-driver coding if you’re already on Codex — Every and Alex Finn both keep GPT-5.6 Sol as their daily driver for lower latency and more generous usage limits.

The effort dial

The real setting isn’t the model — it’s the effort.

Opus 5’s low / medium / high effort toggle is the dial that trades cost for capability — and cranking it to the top is usually the wrong move.

Low
60% pass
~$3.76 / task
For simple tasks like web design; cut cost per task from ~$22 to ~$3.76 in one benchmark yet still hit a 60% pass rate on a long-horizon agentic test — beating a rival top-tier model’s max-effort 59%.
Medium · default
The default balance — it outperformed a rival top-tier model while costing less than that model’s second-highest setting, and Every found Opus 5 actually does better here than at max.
High
Reach for it only on the genuinely hard 20% of work — and remember Opus 5 can do worse the harder it tries, so don’t default here to feel safe.
Match effort to complexity, not habit — the biggest cost lever is simply not defaulting to the highest setting for tasks that don’t need it.
Use the expensive model only to plan, then delegate execution to cheaper models suited to each sub-task — including other vendors’.
Layer in a token-reduction skill — one tested on Opus 5 cut cost roughly 22% at medium effort with similar quality.

⚠️ Note: no cited Anthropic spec names a low/medium/high toggle in these sources — this is creators’ cost guidance (Chase AI) plus Every’s finding that Opus 5 can do worse the harder it tries. Match effort to the task; don’t crank it to feel safe. ↗ Every ↗ Chase AI

Use-case playbooks

Here’s exactly what to build — and how.

The real methods creators demoed, with the actual tools and the video to watch.

Run Opus 5 as a cost-optimized default without blowing your cap

Chase AI
Claude Codeeffort dial
A.Drop the effort level. Benchmark data shows an ~80% cost drop for only a few points of accuracy loss — simple work belongs on low or medium, not max.
B.Plan expensive, execute cheap. Use Opus 5 only to produce the plan, then route execution to cheaper models fit for each sub-task.
C.Try advisor mode. Let a cheap executor do all the tool calls, reads, and writes, and consult Opus 5 only when it gets stuck.

One-shot vibe-coding builds

WorldofAI & Vibe Coding with Naman
Claude Codeone-shot prompt
A.Send one detailed prompt, no follow-up. Opus 5 one-shot a playable COD Zombies-style game, a macOS clone, two Minecraft clones, and a Fall Guys clone with no starter codebase.
B.Lean on it for data-rich front ends. Its post-AI-economy site shipped a working 3D globe and accurate animated stats from a single prompt — “a different league.”
C.Know its soft spots. On a denser flight-sim city with sound, Fable 5 won — split one-shot tasks across categories before you commit.

Agentic workflows that self-verify

Chase AI & Matthew Berman
Claude Codeagentic runs
A.Let it check its own work. On long-horizon tasks Opus 5 validates output against the goal and iterates rather than one-shotting.
B.Hand it problems with no reference answer. It wrote its own computer-vision pipeline to rebuild a machine part it couldn’t view, and built its own test harness for a market-data feed.
C.Trust it on root-cause bugs. Where a rival patched only the symptom, Opus 5 found and fixed the underlying cause.

Build your own benchmark before you switch

Paul J Lipsky & Duncan Rogoff
side-by-side terminalspersonal eval
A.Turn your recurring tasks into the test. Paul ran a landing page, a YouTube script, and a Claude Design motion graphic — near-identical output, but Opus 5 was faster for half the cost.
B.Race the models live, in two terminals. Duncan gave both the same roofing landing page + email sequence + video ad; Opus 5 came in at $5.16, Fable 5 at $5.93.
C.Judge the deliverable, not the rate card. Despite a 2x per-token gap, real cost and time landed close — quality was the actual differentiator.

Migrate a stack built for Opus 4.8 / Fable 5

Every & Alex Finn
CLAUDE.mdskill files
A.Simplify your prompts and skills. Large, complex skill files built for Opus 4.8 make Opus 5 worse — simpler, vaguer prompts and fresh starts win.
B.Tame the personality in CLAUDE.md. Alex Finn added “speak as simply as possible” to stop Opus 5 going in a dozen directions before a simple fix.
C.Split by task, not by ranking. Alex’s stack: Opus 5 for the hardest problems, Fable 5 for planning, GPT-5.6 as daily driver.

The map

Where 10 creators agreed — and threw hands.

The honest part you only get by watching all of them. Tap any name to watch.

New default / all-in

“Comparable output for half of Fable 5’s price — default to Opus 5 now.”

Great value — use surgically

“A top pick for reasoning and cost, but keep other models for daily driving and cost control.”

Skeptical / found dealbreakers

“Smart but temperamental — frustrating with flashes of brilliance, and three dealbreakers.”

Benchmark & bakeoff crowd

“Judge it on the numbers and live head-to-heads — cost-per-task is the metric that matters.”

✓ What nearly all 10 agreed on

  • Opus 5 delivers near-Fable-5 capability at roughly half the price — the through-line of nearly every breakdown.
  • The price held steady: $5/$25 per million tokens, unchanged from Opus 4.8, so the capability jump came at no price increase.
  • Cost-per-task, not price-per-token, is the metric that matters — a cheaper-per-token model can burn more tokens and cost the same.
  • Its standout new skill is self-verification and error recovery — checking its work, building its own test harnesses, and fixing bugs at the root cause.
  • It’s a genuine leap over Opus 4.8, with state-of-the-art agentic coding and a 20x jump on ARC-AGI-3 novel problem-solving.

✗ Where they threw hands

  • Is it your daily driver? Paul J Lipsky and Vibe Coding with Naman say default to Opus 5 now, while Every and WorldofAI keep GPT-5.6 Sol for lower latency and more generous limits.
  • Does more effort help? Every insists Opus 5 does worse the harder it tries and works best at medium/low, whereas Chase AI frames effort as a straight complexity-matched cost dial.
  • Is the personality a bug or a feature? Alex Finn and Every call it verbose, pushy, and prone to quitting early, while Chase AI and Nick Saraev celebrate the same self-directed behavior as smarter self-verification.
  • Who wins front-end builds? Naman and Alex Finn praised Opus 5’s visual quality, but WorldofAI still hands UI-heavy work to the cheaper Kimi K3 and gave Fable 5 the denser flight-sim city.

The 5 moves that pay

1

Switch your default, keep your specialists

Make Opus 5 the default for coding and reasoning to capture the half-price win, but keep Fable 5 for the hardest bugs and GPT-5.6 for latency-sensitive daily work.

2

Measure cost-per-task, not per-token

The sticker price hides the real bill. Run the same deliverable through both models and compare total dollars and time — Opus 5 and Fable 5 often land within pennies.

3

Leave the effort dial at medium

Max effort costs more and can lower quality. Start at medium, drop to low for simple work, and only reach for high on the genuinely hard 20%.

4

Plan expensive, execute cheap

Use Opus 5 to produce the plan, then delegate execution and research to cheaper models. It’s how you stay under weekly caps without losing quality.

5

Rewrite legacy skills before you migrate

Opus 5 degrades on big Opus-4.8-era skill files. Simplify prompts, start fresh, and tame the personality in CLAUDE.md before blaming the model.
