gpt-oss vs Qwen3 vs DeepSeek — which open model should you run in 2026?

Three of the best open models, three different strengths. gpt-oss is the cost-effective all-rounder, Qwen3 owns coding, DeepSeek owns hard… Aliteq Lena Fischer · AI & Local Compute Editor

gpt-oss — cost-effective reasoning + accessible. 20B on 16GB; 120B ≈ 90% of DeepSeek, 3-5× cheaper.

Which open model wins what

Qwen3-Coder — best local coding. 58.7% SWE-bench, 256K context, runs on 24GB.

Which open model wins what

DeepSeek — hard reasoning & algorithms. The benchmark ceiling for logic/math.

Which open model wins what

All-round default: Qwen is the safest general pick; gpt-oss if you want OpenAI's model.

Which open model wins what

By hardware: 16GB → gpt-oss-20b or a Qwen 8-14B; 24GB → Qwen3-Coder 32B.

Which open model wins what

Match to the task — coding vs reasoning vs cost-efficiency, not a single 'winner'.
