Cursor 2.0 launched with Composer-1, an agentic coding model optimized for speed and precision, featuring multi-agent orchestration, built-in browser for testing, and voice-to-code capabilities. OpenAI released gpt-oss-safeguard models (20B, 120B) for policy-based safety classification, open-weight and fine-tuned from gpt-oss, available on Hugging Face and supported by inference stacks like Ollama and Cerebras. Goodfire and Rakuten demonstrated sparse autoencoders for PII detection matching gpt-5-mini accuracy at significantly lower cost. The Cursor 2.0 update also includes a redesigned interface for managing multiple AI coding agents, marking a major advancement in AI IDEs. "Fast-not-slowest" tradeoff emphasized by early users for Composer-1, enabling rapid iteration with human-in-the-loop.
