GLM-5 Free

GLM-5 Free is a no-cost variant aligned with Zhipu AI's flagship GLM-5 line, a model positioned as a capable reasoning system with strong Chinese and English bilingual performance and agentic tool use. The base model is described as a flagship reasoning design with elite bilingual capabilities, and it is released as open source, which is consistent with the open-weights flag on this OpenCode Zen listing. In feature comparisons, GLM-5 is marked as supporting coding and reasoning workloads, while vision and multimodal support are not indicated, making it best suited for text-only generation tasks rather than image or audio input pipelines. Practically, GLM-5 Free is intended for developers who want to explore GLM-5's reasoning and coding potential without hosting costs, particularly for long-context agentic workflows where the model can chain tool calls and reason over extended prompts. Its strengths sit in code generation, Chinese-English bilingual reasoning, and tool-driven agent behaviour, which makes it a reasonable pick for prototyping assistants, code helpers, and automation pipelines rather than multimodal or vision-centric applications.

Because the OpenCode Zen listing is no longer marked as a current offering, the variant is treated as superseded rather than actively maintained, so users evaluating it should anchor expectations to the original GLM-5 design rather than to any newer fine-tuning or alignment updates beyond its listed lifecycle. The stocked entries describe GLM-5 as a reasoning-focused flagship with open-source distribution and agentic tool use highlighted as core capabilities, with coding workflows as a primary intended use case. For teams comparing free model tiers, GLM-5 Free stands out as a text-only, open-weights option aimed at bilingual reasoning and code-centric agentic tasks, while leaving room for newer GLM-family releases to take its place in production pipelines.
