On October 5, 2026, Cantina Security and Yeta Labs jointly released apex-flash-1, an open-weights model specifically trained for vulnerability research. The model is a reinforcement learning fine-tune of Z.ai's GLM-5.3-Flash and is now available on Hugging Face under the MIT license. For deployment, the weights are compatible with vLLM, SGLang, and Transformers, though the BF16 precision requires approximately 640 GB of GPU memory.

How is heat calculated?About the methodHide
Heat counts how many independent sources covered a story in the last 48 hours: one source counts once no matter how many posts it published, decaying with a 24-hour half-life. What ranks first is what many people are talking about.
