How they compare
Qwen 2.5 VL 7B comes from Alibaba and Qwen 2 VL 7B from Alibaba. This comparison is built entirely from structured specs — parameter count, VRAM by quantization, context window, license, and published benchmark scores — so the verdict below reflects measurable differences rather than marketing claims.
Qwen 2.5 VL 7B and Qwen 2 VL 7B share the same 7B parameter class. Both need about 6 GB of VRAM at a Q4 quantization, so they fit the same GPU tier.
Where they overlap on benchmarks, Qwen 2 VL 7B takes OCRBench with 845 against 86.4 — a decisive 758.6-point margin. On DocVQA the edge goes to Qwen 2.5 VL 7B (95.7 vs 94.5). For workloads weighted toward that benchmark, Qwen 2 VL 7B is the stronger default.
For long-context work, Qwen 2.5 VL 7B offers the bigger window (125k vs 32k tokens).
Memory, quantization & throughput
Across quantization levels, Qwen 2.5 VL 7B requires Q4 ≈ 6 GB, Q5 ≈ 7 GB, Q8 ≈ 10 GB, FP16 ≈ 18 GB, while Qwen 2 VL 7B requires Q4 ≈ 6 GB, Q5 ≈ 7 GB, Q8 ≈ 10 GB, FP16 ≈ 18 GB. In practice Qwen 2.5 VL 7B fits an 8 GB card at Q4, so plan your GPU around the Q4 or Q5 figure unless you specifically need the higher fidelity of Q8 or FP16.
Without a GPU, Qwen 2.5 VL 7B needs roughly 10 GB of system RAM to run on CPU and Qwen 2 VL 7B about 10 GB — workable for offline use but far slower than GPU inference. On a mid-range GPU you can expect on the order of 25 tokens/sec from Qwen 2.5 VL 7B and 25 from Qwen 2 VL 7B, scaling up to 60 and 60 tokens/sec on high-end hardware.
