Sonnet 5.5 pricing leaks from binary: identical to GPT-6 Sol
kimmonismus · x · 2026-09-29
LuminaBench extracted Claude Sonnet 5.5 pricing from the binary: $2/M input, $10/M output, $0.20/M cache reads, $2.50/M 5-min cache writes ($4/M for 1h), with 1M context and 128K max output. The pricing exactly matches GPT-6 Sol, and the poster wonders whether it will actually outperform Sol.
