WSL2 vllm fails Qwen2.5-7B-1M on 6GB VRAM, Windows transformers succeed

A developer encountered unexpected memory limitations when attempting to run the Qwen2.5-7B-1M model on a consumer laptop with 6GB of VRAM. While the Windows "transformers" library could handle a 4k context by spilling over into system RAM, the WSL2 environment with "vllm" failed to load the model, indicating that the Windows OS's memory management was the enabler, not the inference engine itself. The developer also found that free tiers on platforms like GitHub Models have limitations on model availability and context length, with some advanced models like GPT-5 being unavailable or restricted.
