OpenAI and Anthropic launched competing AI coding models on Wednesday, kicking off what industry observers are calling the "AI coding wars." The synchronized releases of OpenAI's GPT-5.3-Codex and Anthropic's Claude Opus 4.6 mark the beginning of a high-stakes battle to capture the enterprise software development market, according to VentureBeat. The announcements came during a week of heightened competition between the two AI giants, who are also set to air competing Super Bowl advertisements on Sunday.
OpenAI's GPT-5.3-Codex is being touted as the company's most capable coding agent to date, VentureBeat reported. The launch was timed to coincide with Anthropic's unveiling of its flagship model upgrade, Claude Opus 4.6. Executives from both companies have been publicly trading barbs over business models, access, and corporate ethics, further escalating the rivalry.
Meanwhile, researchers from Stanford, Nvidia, and Together AI developed a new technique called Test-Time Training to Discover (TTT-Discover). This technique optimizes GPU kernels, achieving results twice as fast as those achieved by human experts, VentureBeat reported. TTT-Discover allows the model to continue training during the inference process, updating its weights for the specific problem. This approach challenges the current enterprise AI strategies that often rely on "frozen" models.
In other news, engineers at Blue Origin have been debating the economics of reusing the second stage of the New Glenn rocket, according to Ars Technica. The debate, which has been ongoing for at least 15 years, mirrors similar discussions SpaceX had regarding its Falcon 9 rocket. SpaceX eventually abandoned its goal of a fully reusable second stage.
In the world of supercars, Lamborghini is set to release the Temerario, the replacement for the Huracán, Ars Technica reported. The Temerario is expected to be an all-new performance car.
Finally, athletes competing in the 2026 Milano Cortina Winter Olympics and Paralympics will need high-quality sleep to perform at their best, according to Wired. The games are scheduled to run from February 6 to 22, and creating an optimal sleep environment in an unfamiliar setting is always a risk.
