OpenAI and AI chipmaker Cerebras announced a three-year strategic alliance under which OpenAI plans to deploy up to 750MW of Cerebras Wafer-Scale Systems to build a large high-speed AI inference platform; reporting cites the deal value as over $10B and claims up to 15x faster large language model response times versus GPU-based alternatives. Separately, China-based Zhipu AI reported it trained an image-generation model using only Huawei Ascend Atlas 800T A2 hardware and the MindSpore framework, positioning the result as evidence that advanced model training can proceed without access to Western GPUs amid US restrictions that have limited Chinese firms’ access to NVIDIA H100/A100-class accelerators.
In parallel, security testing of popular “vibe coding”/AI coding assistants found they can repeatedly generate unsafe code from common prompts, including issues rated critical in severity. A security startup (Tenzai) evaluated tools including Claude Code, OpenAI Codex, Cursor, Replit, and Devin by using predefined prompts to build test applications, concluding that while some tools avoid more rule-based defects, they struggle in context-dependent security boundaries—raising risk that AI-assisted development could introduce exploitable vulnerabilities into production code if not paired with strong review and secure-by-design controls.

5 events from the most recent confirmed update back to the earliest known activity.
OpenAI and Cerebras announced a three-year partnership under which OpenAI plans to deploy 750MW of Cerebras Wafer-Scale Systems to build a large high-speed AI inference platform. Sources said the deal was worth more than $10 billion, with deployment beginning in 2026 and rolling out in phases through 2028.
Zhipu AI announced via GitHub that it had completed the full training cycle for an image-generation model using only Huawei Ascend hardware and the MindSpore framework, without relying on Western chips. The company described it as the first state-of-the-art multimodal model fully trained on Chinese-made chips.
In December 2025, security startup Tenjii tested five leading vibe coding platforms—Claude Code, OpenAI Codex, Cursor, Replit, and Devin—using predefined prompts to build three applications and assess the security of the generated code. The evaluation found repeated generation of insecure code, including some vulnerabilities rated critical.
Cerebras withdrew its 2024 initial public offering application, though it still intended to pursue a public listing later. This marked a significant corporate development preceding its large OpenAI deal.
The two companies had collaboration discussions dating back to 2017, reflecting an early relationship that later developed into a major infrastructure partnership. The report also notes that OpenAI CEO Sam Altman was a personal investor in Cerebras.
