Huawei launches openPangu 2.0, open-sourcing June 30; Pro version has 505B total params but only 18B active

Huawei Released openPangu 2.0 (Will open source on June 30)

Huawei announced openPangu 2.0 at HDC 2026. Two sparse models: Pro at 505B total / 18B active, Flash at 92B total / 6B active, hitting a 28:1 sparsity ratio. 512K context window, heavily optimized for Ascend chips with claimed 2x single-card throughput vs mainstream open-source models. Richard Yu said the large total param count reflects limited compute left for Huawei after supporting other Chinese enterprises, so the focus is on latency and throughput gains. Open-sourcing starts June 30, covering weights, inference code, training code, and training operators. I'd hold off until we see actual benchmarks—the post only gives relative improvement percentages, no absolute scores.

Why it matters: Huawei announced openPangu 2.0 at HDC: two sparse variants, Pro 505B/18B active and Flash 92B/6B active, 512K context, open-sourcing June 30. The 28:1 sparsity ratio is a technical hook, and the 2x Ascend throughput claim needs independent verification. Score stays below 80 be...
