GLM 4.6 is Z.ai's foundation model with a 198K-token context window, released in late 2025 as an incremental update to the GLM 4.5 series.
- Strengths
- The model handles extended document processing and multi-turn reasoning across a substantially larger context window than the preceding GLM 4.5 generation.
- Best for
- Applications requiring longer context handling without the overhead of later foundation models like GLM 5 and beyond.
- Limitations
- GLM 4.6 has been superseded by GLM 5 (released early 2026) and subsequent releases, which offer either expanded context windows, multimodal capabilities, or optimized inference variants; it lacks the 1M-token context of GLM 5.2 and does not support multimodal input like GLM 4.6V.
