OpenAI announced the launch of its Codex agentic coding tool and a new model called GPT-5.3 Codex. The company says the model expands Codex's abilities from simple code writing to handling nearly any developer task, can create complex games and apps from scratch, runs 25 percent faster than its predecessor, and was partially built using earlier versions of itself. The release follows a near‑simultaneous launch by Anthropic, which moved its release 15 minutes earlier, sparking a brief race to market. Leia mais →

A hands‑on comparison of Google’s Gemini 3 Pro and Gemini 2.5 Flash models shows that the higher‑tier model delivers deeper reasoning and smoother code generation for vibe‑coding projects, while the faster model requires more manual prompting and frequent fixes. The experiment highlights trade‑offs between speed and depth, with Gemini 3 Pro generally producing more complete results with fewer iterations. Leia mais →
