About

CodeGen is an open-source model for program synthesis. Trained on TPU-v4. Competitive with OpenAI Codex.

About

GPT-5.6 Pro is not officially announced, but public discussion describes it as the expected higher-reasoning variant of a possible GPT-5.6 release. A pro-tier model for harder professional work, especially coding, research, information synthesis, data analysis, document-heavy tasks, business, legal, education, and scientific workflows. GPT-5.6 is being prepared as a meaningful improvement over GPT-5.5, with expected gains in reasoning quality, efficiency, safety, coding, and agentic task performance. Reported signals include a briefly visible Codex rollout-mapping entry referencing GPT-5.6 and prediction-market speculation around a late-June launch. Rumor coverage also claims some ChatGPT Pro users may have seen stealth-tested behavior under the GPT-5.5 Pro label, with sharper results, longer processing for complex tasks, stronger backend coding, improved logic, and more creative technical generation such as 3D, SVG, simulation, and UI-related outputs.
