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

OpenAI is releasing its Codex agentic coding tool in research preview. Codex lets developers delegate simple, routine programming tasks to software engineering agents that can generate production-ready code, documenting the work as they go. Codex can work on many tasks in parallel doing things like writing software features, answering questions about a codebase, fixing bugs, and proposing pull requests for review. According to OpenAI, “each task runs in its own cloud sandbox environment,” preloaded within the user’s repository. OpenAI began releasing Codex last week to ChatGPT Pro, Enterprise, and Team users, with support for Plus and Edu coming soon. Continue reading OpenAI Adds Codex Software Agent to Some ChatGPT Plans
