Claude Opus 5 brings advanced AI performance at lower costs. Anthropic designed this model for coding, research, and business tasks.
The company says users receive strong results without paying premium prices.
Claude Opus 5 Brings Powerful AI Features
Better Performance Than Previous AI Model
Claude Opus 5 is Anthropic’s newest frontier AI model. It supports coding, research, business, and knowledge work. The model improves greatly over Claude Opus 4.8 performance. It keeps exactly the same API pricing structure.
Users can adjust effort settings for different workloads. Higher effort delivers smarter answers during difficult tasks. Lower effort saves tokens and reduces operating costs. Faster responses also become possible with lower effort.
Anthropic launched this model during intense AI competition. Chinese open-weight models continue challenging American AI companies. Kimi K3 and GLM 5.2 remain strong competitors. These models mainly focus on affordable AI performance.
Close Performance Against Claude Fable 5
Anthropic says Opus 5 rivals Claude Fable 5 closely. The company compared both models across many benchmarks. Opus 5 outperformed Fable 5 on ten metrics. It reached similar intelligence at much lower costs.
Earlier, Claude Fable 5 received temporary restrictions overseas. Cybersecurity concerns surrounded its advanced capabilities and performance.
Opus 5 offers similar abilities for everyday users. Anthropic also claims Opus 5 exceeded GPT-5.6 Sol. Selected benchmark tests showed stronger overall performance.
Sets Strong Benchmark Results
Excellent Coding And Computer Task Scores
Claude Opus 5 delivered impressive benchmark scores after testing. Frontier-Bench version 0.1 showed major improvements clearly. Opus 5 more than doubled Opus 4.8 performance. It completed difficult tasks at lower average costs.
CursorBench 3.2 measures real software development abilities carefully. Opus 5 finished within 0.5 percent of Fable. It achieved this score at half the cost.
OSWorld 2.0 also showed impressive benchmark improvements. Opus 5 beat Fable 5 during computer tasks. It completed work at just one-third cost.
Better Problem Solving During Complex Jobs
Anthropic says Opus 5 checks work more carefully. It finds software bugs much more accurately. The model continues difficult jobs without stopping early. It even discovered one missed software edge case.
Testing also included practical engineering work examples.
- Built a complete computer vision pipeline independently.
- Reconstructed machine parts into FreeCAD 3D models.
- Helped build market data feeds quickly.
- Completed difficult engineering work within one session.
These results come from Anthropic’s internal testing process. Everyday user experiences may differ across different workloads.
Offers Lower Pricing And Better Safety
Affordable Pricing For More Users
Claude Opus 5 costs $5 per million input tokens. Output tokens cost $25 per million tokens. These prices match Claude Opus 4.8 exactly.
Claude Fable 5 costs twice as much overall.
- Input tokens cost $10 per million.
- Output tokens cost $50 per million.
Kimi K3 remains slightly cheaper than Opus 5.
- Input tokens cost $3 per million.
- Output tokens cost $15 per million.
Tokens measure how much AI processing users consume. Larger workloads always require more tokens overall.
Many businesses now monitor AI spending carefully. Companies like Uber and Walmart restrict AI usage. Lower pricing helps enterprises reduce growing operational expenses.
Strong Safety Measures Remain Available
Anthropic added important safeguards inside Claude Opus 5. The model avoids advanced offensive cybersecurity training completely. It also limits risky biology-related capabilities carefully.
Developers can still identify software vulnerabilities safely. High-risk requests remain blocked by built-in protections. Anthropic says Opus 5 stays behind Mythos 5. This mainly applies to cyber and biology research.
Claude Opus 5 now powers Claude Max automatically. It also became the strongest Claude Pro model. Standard Team subscribers also receive improved AI performance.
Claude Opus 5 delivers excellent AI performance at affordable prices. Strong benchmark results, better safety, and lower costs improve its value.
Anthropic offers developers and businesses powerful AI without increasing operating expenses.
