Claude Sonnet 4 (Thinking)
thinkHand-maintained price, verified 10d ago · cached input $0.30 /M · Retired with Claude Sonnet 4. Same per-token price as the standard variant; reasoning mode burns significantly more output tokens per request. Last published price.
Benchmarks
preference
Crowdsourced pairwise human preference rankings of LLM responses. Higher Elo means more frequently preferred by users.
coding
Continuously refreshed coding benchmark drawing from LeetCode, AtCoder, and Codeforces; reduces benchmark contamination.
performance
Median output speed in tokens per second over the last 14 days on the model maker's own API, measured nightly with a fixed ~800-token prompt and ~250-token answer. Models not yet probed fall back to a dated manual figure. Higher is faster.
Median time from request to first streamed token in milliseconds over the last 14 days on the model maker's own API, using the same nightly probe prompt. Lower is snappier; reasoning models are penalised here because they think before talking.
general
Contamination-controlled average across every task category in the latest rolling release (e.g. reasoning, coding, data analysis, research, browsing, long-horizon tasks). Questions are rotated with each release and graded against objective ground truth, removing the need for LLM-as-judge scoring. Only models with a score in every category get an average.
data analysis
Rolling contamination-controlled data-analysis evaluation. Table comprehension, CSV / spreadsheet reasoning, SQL-style joins, and chart interpretation. Refreshed every six months with new tables and questions to minimise contamination.

Effort variants
Same API model, different reasoning budget. Thinking / xHigh modes usually score better on reasoning benchmarks but emit many more output tokens per request. Higher effort is also an alternative to running a team of agents: check whether the extra points are worth the extra output.

Output tokens are the typical multiple of a standard answer that the cost calculator assumes for each effort level; hidden reasoning bills as output.
