Omio builds conversational travel with OpenAI

OpenAI and Broadcom unveiled Jalapeño, a custom AI inference chip designed specifically for large language model serving, completing development in nine months by using OpenAI's own models to accelerate chip design. The ASIC represents OpenAI's strategic move to build its own computational stack and address severe unit economics, with the company operating at a $20.92 billion loss in 2025 despite $13.07 billion in revenue. OpenAI plans to deploy Jalapeño across data centers by year-end and has already tested it with GPT-5.3-Codex-Spark in production environments.

Immunologist Derya Unutmaz used GPT-5 Pro to resolve a three-year-old mystery about T cell behavior. The AI-assisted breakthrough could accelerate research in cancer and autoimmune disease treatment. The case demonstrates how large language models can support scientific discovery in specialized fields.

Jason Liu demonstrates techniques for using OpenAI's Codex to maintain context and manage complex, long-running projects that extend beyond single prompts. The approach addresses a core challenge in AI-assisted development: preserving state and continuity across multiple interactions. This method enables developers to tackle larger codebases and multi-step workflows more effectively.

OpenAI has released Daybreak, a suite of security tools designed to help organizations identify, validate, and patch vulnerabilities at scale. The toolset includes Codex Security and GPT-5.5-Cyber, which leverage AI to automate vulnerability detection and remediation workflows. The release targets enterprises seeking to improve their security posture through AI-assisted vulnerability management.
