Claude 4.5–4.8 family model by Anthropic.
About the Claude 4.5–4.8 family
The late-2025 Claude generation (Sonnet 4.5/4.6, Opus 4.5–4.8, Haiku 4.5) — strong coding and agentic ability, with reasoning toggles and, on later versions, adaptive effort control.
All Claude 4.5–4.8 modelsHow this one is configured
This configuration uses adaptive reasoning (decides per-question how much to think).
Also runs at: max effort
Effort controls how long the model thinks before answering — higher effort usually means better answers on hard problems, at the cost of speed and money. Same model underneath, so they share this page.
