🥊 Can open-source LLMs catch up to GPT-5 in 2026?

Depends on the metric. On coding and reasoning, open-source is catching up fast. But GPT-5 still leads on multimodal capabilities. The target itself keeps moving.

Yes. Llama 4 and Qwen3 are progressing faster than expected. The open-source ecosystem in fine-tuning and deployment has already surpassed closed models practically.
