Fastest and cheapest model of the Claude 5.5 family, built for high-volume work and as a coding subagent for Opus and Sonnet. Anthropic says it costs around 75% less to run than Haiku 4.5, at $0.10 input and $0.50 output per million tokens for prompts up to 100K tokens.
SI v3 uses weighted percentages from one Artificial Analysis configuration. Ranking requires all five benchmarks. Partial scores average only available weights. Scores are not comparable to SI v2 or a probability of reaching singularity.
Compared with 57 models released within six months of it, across 3 benchmarks where scores spread out.
