Wasmer used OpenAI Codex with GPT-5.5 to build a Node.js edge runtime 10-20x faster

Wasmer used OpenAI's Codex powered by GPT-5.5 to build a Node.js runtime for edge computing, reporting 10x to 20x development acceleration and shipping in weeks instead of months. The case study is published on the OpenAI blog as a deployment showcase. It provides concrete evidence of agentic coding tools compressing development timelines for systems-level infrastructure work.
