OpenAI launched a new coding model, GPT-5.3-Codex-Spark, on Thursday, February 12, 2026, marking its first major inference partnership outside of its traditional Nvidia-dominated infrastructure. The model, designed for near-instantaneous response times, runs on hardware from Cerebras Systems, a chipmaker specializing in low-latency AI workloads, according to VentureBeat. This move comes at a pivotal moment for OpenAI, amidst a strained relationship with Nvidia, criticism over advertisements in ChatGPT, a new Pentagon contract, and internal organizational changes.
The partnership with Cerebras Systems represents a significant shift for OpenAI. VentureBeat reported that the company's decision to utilize Cerebras chips highlights a strategic move to diversify its hardware infrastructure. The new model, GPT-5.3-Codex-Spark, is a stripped-down coding model designed for speed.
Simultaneously, the landscape of AI is evolving rapidly. Google Chrome introduced WebMCP (Web Model Context Protocol) in early preview in Chrome 146 Canary, a web standard developed jointly by Google and Microsoft, incubated through the W3C's Web Machine Learning community group, as reported by VentureBeat. WebMCP aims to transform every website into a structured tool for AI agents, potentially ending the era where agents struggled to navigate websites.
The Chinese AI sector also saw significant advancements. Chinese companies have repeatedly delivered AI models that match the performance of leading Western models at a fraction of the cost, according to MIT Technology Review. Last week, Moonshot AI released its open-weight model, Kimi K2.5, which rivaled Anthropic's Claude Opus on some benchmarks, but at one-seventh the price. Alibaba's Qwen family of models has overtaken Meta's Llama on Hugging Face, after ranking as the most downloaded model series in 2025 and 2026.
In other news, a new web and mobile agentic IDE called Omnara, developed by Kartik, Ishaan, and Christian, is being built for Claude Code and Codex, as announced on Hacker News. Omnara allows users to run and interact with coding agents from anywhere, even on mobile devices. "We started using Claude Code early last year and quickly ran into a pattern: agents could work for long stretches on their own, but progress would stall whenever they needed follow-up input," the Omnara team stated.
Finally, researchers have developed a shapeshifting robot with customizable limbs that can morph into the shape of various animals, as reported by Nature News. This robot, capable of adapting its anatomy, represents a step forward in robotics.
