Top Stories

1. OpenAI Slams Anthropic to Investors: “Substantially Ahead” in Compute

Date: April 9

OpenAI sent a memo to investors slamming main competitor Anthropic, characterizing it as “operating on a meaningfully smaller curve” and compute-constrained. OpenAI stated it plans to have 30 gigawatts of compute by 2030, while expecting Anthropic to have roughly 7-8 gigawatts by end of 2027.

The memo noted: “Even at the high end of that range, our ramp is materially ahead and widening.” Both companies are collectively valued at over $1 trillion and gearing up for possible IPOs this year, while trying to convince investors they have sustainable business models.

Impact: OpenAI-Anthropic competition extends from technical level to investor relations warfare, reflecting market positioning battles ahead of IPOs.


2. Zhipu AI Open-Sources GLM-5.1: 744B Parameter MoE Model Free to Use

Zhipu AI released its flagship model GLM-5.1 as open-source while raising API prices by 10%. This is a 744-billion-parameter mixture-of-experts (MoE) model, activating 40 billion parameters per forward pass, with 200K context window. On SWE-Bench Pro (expert-level real-world software engineering), it reportedly defeated both Claude Opus 4.6 and GPT-5.4.

The model is released under MIT license, with usage cost being only electricity expenses. This is the company’s second price increase this year, following a comprehensive reform in February that raised coding subscription plan rates by over 30%.

Impact: Chinese AI enterprises are exploring “open-source + commercialization” dual-track strategy to maintain advantage in global competition.
