Anthropic ke benchmarks
| Benchmark | Opus 5.5 | Sonnet 5.5 | Haiku 5.5 |
|---|---|---|---|
| Terminal-Bench 4.0 (agentic coding) | 66.4% | 70.6% | 39.2% |

Do saavdhaniyan: ye Anthropic ke apne numbers hain, independent test nahi. Aur Haiku ka OSWorld score alag subset par hai, isliye seedhi tulna nahi.
Hairani: agentic coding me Sonnet, Opus se aage
Terminal-Bench 4.0 par Sonnet 5.5 ka 70.6% hai aur Opus 5.5 ka 66.4% — wo bhi aadhi keemat par. Anthropic phir bhi mushkil, khule kaam ke liye Opus ko behtar batata hai, par saaf-saaf define kiye kaam ke liye sasta model hi samajhdaari hai.
Kis kaam ke liye kaun sa
| Agar aap… | Use kijiye |
|---|---|
| Coding assistant ya production agent bana rahe hain | Sonnet 5.5 |
| Lambi research ya mushkil multi-step problem | Opus 5.5 |
| Bahut zyada summary, classification ya data extraction | Haiku 5.5 |
| Bade model ke neeche sub-agents chala rahe hain | Haiku 5.5 |
| Claude Code se terminal me coding | Default Sonnet 5.5, mushkil kaam me Opus 5.5 |
Teen baatein jo bill badalti hain
- Opus 5.5 hamesha sochta hai. Thinking mode band nahi hota, isliye chhoti request me bhi reasoning token lagte hain.
- Haiku ki 1 lakh token wali line. Prompt 1 lakh token se bada hua to Haiku 5.5 paanch guna mehenga ho jata hai.
- Caching. Baar-baar wahi instructions aur documents bhejne wale agents prompt caching zaroor use karein — aksar headline price se zyada farak isi se padta hai.
Anthropic USD me bill karta hai; Indian teams ko upar se GST aur card charges bhi dene padte hain. Apne token count ke saath AI cost calculator me mahine ka kharch dekhiye.
