GLM-5.2 IS THE MOST IMPRESSIVE OPEN MODEL I'VE EVER SEEN AND IT'S NOT CLOSE. - Trails Claude Opus 4.8 by roughly 1% on the hardest agentic coding benchmarks. - Beats GPT-5.5 on most of them. - Clears Opus 4.7 by double digits. This is a 753 billion parameter, MIT-licensed model running at $1.40 per million input tokens — roughly 70% cheaper than the closed frontier. A few months ago, this gap between open and closed would have been unthinkable. Insanely bullish for the future of open source.(CyrilXBT)
