CoinEx News: Three frontier AI models landed in an eight-day window between April 16 and April 24. Anthropic released Claude Opus 4.7 on April 16 with upgrades in software engineering, higher-resolution vision and self-verification. OpenAI launched GPT-5.5 on April 23 with a one-million-token context window, according to OpenAI. DeepSeek released its open-source V4 preview on April 24 — a one-trillion-parameter MoE model, reporting 81% on SWE-bench.

The most structurally significant signal around V4 is the shift toward a Huawei Ascend-based stack: reports say V4 will run on Huawei chips, underscoring accelerating compute decoupling from Nvidia/CUDA.
