Jeremy Howard lauds blind GLM-5.2
Jeremy Howard, co-founder of Fast.ai, shared high praise for Z.ai's open-weights model GLM-5.2, describing it as a fast, inexpensive, and highly nuanced competitor to GPT-5.5. While lauding its judgment and long-context capabilities, Howard noted that its lack of vision support is currently its only major limitation.
// ANALYSIS
The rapid progress of open-weights models like GLM-5.2 is narrowing the performance gap with frontier proprietary models, though multimodal capabilities remain a key differentiator.
- –**Proprietary Competitiveness:** GLM-5.2 is noted to match or exceed frontier models like GPT-5.5 in reasoning nuance and contextual handling at a fraction of the cost.
- –**Multimodal Bottleneck:** The absence of image processing is the primary barrier keeping GLM-5.2 from claiming the top spot in overall model rankings.
- –**Infrastructure Importance:** Howard emphasizes that choosing a fast inference provider like Fireworks AI is crucial to realizing the model's full speed potential.
