Elon Musk stated that artificial intelligence is "improving exponentially" while commenting on recent advancements in open-source large language models. The remark highlights a significant acceleration in AI capabilities across the sector. Multiple open-source models, including GLM 5.3 Flash, DeepSeek V4.1 Flash, Qwen 3.8 Next Flash, and Qwen 3.8 27B, have now collectively surpassed mainstream models that were considered frontier-level intelligence at the end of 2025. This shift demonstrates rapid progress in open-weight model performance relative to previous industry benchmarks.
