A maker looks beyond Codex to GLM-5.2 and easier model access
A firsthand coding workflow started with Codex for vibe coding, and it worked well at first. Over time, reliability problems, quotas, uneven performance, and constant workarounds made it harder to focus on building. GLM-5.2 became interesting because public rankings, coding tests, and community checks suggested it was close to such as Claude Opus and GPT-5.5 on many coding tasks.
It was also presented as open-source and much cheaper to run. The bigger problem was finding a provider that was comfortable for real . Official options had frustrating quotas, some providers were overloaded, and others had rate limits that made long work sessions painful.
The goal behind Openference was to make one API key and one endpoint work with tools such as OpenCode, Cursor, and Codex CLI through an setup.
Key points
- Codex felt useful at first, but reliability, quotas, and uneven performance became blockers.
- GLM-5.2 is presented as close to Claude Opus and GPT-5.5 on many coding tasks.
- GLM-5.2 is described as open-source and much cheaper to run.
- matters because quotas, overload, and rate limits can interrupt long .
- Openference aims to offer one API key and one endpoint for tools like OpenCode, Cursor, and Codex CLI.
