Qwen4 and the One-Million-Token Window: The Real Constraint Is VRAM
Alibaba brings Qwen4 to a one-million-token context window. The news emerges from a pull request in qwen-code: Qwen4-27B is expected tomorrow at the Apsara event in the Netherlands, while Qwen4-max is dated November 1st with October 1st as a likely placeholder. The analysis focuses on VRAM costs for local deployment and the consequences for TCO and fine-tuning pipelines.
