GPT-5.5 is here. So is DeepSeek V4. And honestly, I am tired of version numbers.

OpenAI launched GPT-5.5, citing stronger benchmark results and a wider ChatGPT-centered platform push.

Within two days, DeepSeek followed with a V4 preview, underscoring the pace of AI model launches.

DeepSeek stressed Huawei-chip compatibility and open-source infrastructure, contrasting with OpenAI’s ecosystem strategy.

The releases highlight that AI rivalry is now about platforms, hardware dependence, and geopolitical alignment, not just model scores.
