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

Claude Opus 4 and 4.1 now have the discrete ability to end “abusive” or “harmful” conversations in consumer chat interfaces. Anthropic says the feature was developed as part of its exploratory work on the protection and well-being of its AI models. The company also envisions broader safety uses, although it does point out that having a model defensively terminate a chat is an extreme measure, intended for use in rare cases. “We’re working to identify and implement low-cost interventions to mitigate risks to model welfare,” Anthropic explains, qualifying it is unsure “such welfare is possible.” Continue reading New Anthropic Safety Updates Focus on Claude’s Well-Being

Anthropic has launched the Claude Enterprise subscription plan to compete with OpenAI’s ChatGPT Enterprise business solution. Focused on security and administrative controls, Claude Enterprise is designed to help organizations securely collaborate with artificial intelligence using proprietary internal data. Pricing will vary based on the number of seats and how Claude is used but is expected to be more expensive than Claude Pro and Claude Teams ($20 and $25 per month, respectively). An expanded 500K context window, more usage capacity, and a native GitHub integration for work on entire codebases are advantages Anthropic touts for Claude Enterprise.
