San Francisco-based AI startup Anthropic has released a smaller, cheaper Claude model called Haiku 4.5 that can reportedly outperform larger models that are only a few months old. In terms of coding skills, Haiku 4.5 performs comparably to Claude Sonnet 4 and OpenAI’s GPT-5, per the SWE-bench Verified leaderboard. “What was recently at the frontier is now cheaper and faster,” Anthropic suggests, noting that just “five months ago, Claude Sonnet 4 was a state-of-the-art model” and “today, Claude Haiku 4.5 gives you similar levels of coding performance but at one-third the cost and more than twice the speed.” Continue reading Anthropic’s New Claude Haiku 4.5 is Available to Free Users

Anthropic has released its latest frontier AI model, Claude Sonnet 4.5, built for high-performance coding and building complex agents. Anthropic claims it is “the best coding model in the world” and “the best model at using computers,” with substantial gains in reasoning and math. Claude Sonnet 4.5 is distinctive in that it can build “production-ready” applications and is not limited to prototypes, Anthropic says, describing it as a major gain over previous models. The new model also excels in research as well as enterprise basics like cybersecurity and finance, per Anthropic. Continue reading Anthropic Claude Sonnet 4.5 Good at Coding and Collegiality
