GLM 5.2 is the first frontier level open-weight model And it’s seriously challenging OpenAI and Anthropic. GLM 5.2, from Z.ai, is reaching frontier-level performance in coding and AI agents with up to a 1M-token context window. But the real shift is control. Companies can run it on their own infrastructure, adapt it to internal data, control cost and latency, and reduce dependence on closed APIs. If open models keep closing the performance gap, OpenAI and Anthropic could lose pricing power, distribution control, and enterprise lock-in. #Codex #Claudecode #AITools #Engineer #OpenSource
