GPT-5.2 vs Qwen3.6-35B-A3B

GPT-5.2 (2025) and Qwen3.6-35B-A3B (2026) compare a standalone API model against a coding-specialized model. GPT-5.2 ships a 400k-token context window, while Qwen3.6-35B-A3B ships a 262k-token context window. On SWE-bench Verified, GPT-5.2 leads by 6.6 pts. On pricing, Qwen3.6-35B-A3B costs $0.15/1M input tokens versus $1.75/1M for the alternative. This page treats the result as workflow and deployment fit, not a universal model winner.

Treat this as a product-type comparison: GPT-5.2 is standalone API model, while Qwen3.6-35B-A3B is coding-specialized model. Choose based on workflow fit before reading any benchmark or price row as decisive.
