OpenAI launched its GPT-5.3-Codex-Spark coding model on Thursday, February 12, 2026, marking a significant move beyond its traditional reliance on Nvidia hardware. The new model, designed for near-instantaneous response times, runs on hardware from Cerebras Systems, a Sunnyvale-based chipmaker specializing in low-latency AI workloads, according to VentureBeat. This development comes at a pivotal moment for OpenAI, amidst a strained relationship with Nvidia, mounting criticism, and internal organizational changes.
The release of GPT-5.3-Codex-Spark coincided with the release of Anthropic's Opus 4.6, as noted by AI influencer Matt Shumer in a viral blog post on X, which garnered over 55 million views. Shumer's essay, written in a "breathless tone," warned of the potential for AI to disrupt and automate knowledge work, particularly impacting coders. "Something clicked," Shumer wrote, describing the moment he realized the rapid advancements in AI.
The shift to Cerebras chips represents OpenAI's first major inference partnership outside of Nvidia. This move could be seen as a strategic diversification, given the current challenges the company faces.
Meanwhile, the AI landscape continues to evolve rapidly. Chinese companies have been making significant strides, with models like DeepSeek's R1 reasoning model and Moonshot AI's Kimi K2.5 matching the performance of Western models at a lower cost, according to MIT Technology Review. Kimi K2.5, for example, was priced at roughly one-seventh of the cost of Anthropic's Claude Opus. Alibaba's Qwen family of models has also overtaken Meta's Llama on Hugging Face, after ranking as the most downloaded model series in 2025 and 2026.
The advancements in AI also raise concerns about potential misuse. Cybersecurity researchers are increasingly vigilant about malicious software. One example involved a ransomware strain that encrypted files on a victim's system, making them unusable until a ransom was paid, as reported by MIT Technology Review.
