Dimension-by-dimension analysis
Reasoning & overall intelligence
Qwen3.8-Max leads the overall aggregate by 10 points (82 vs 72). That is a meaningful, not marginal, edge on hard, multi-step reasoning, while GPT-5.6 Sol remains a strong generalist that is not out of its depth on routine work.
Agentic coding
This is a clear gap: GPT-5.6 Sol scores 88 against 77. On multi-file edits, SWE-style tickets and long-horizon agent loops GPT-5.6 Sol needs fewer correction turns; Qwen3.8-Max is still competent for scripts and assisted completion but trails as task complexity rises.
Multimodal
Qwen3.8-Max leads multimodal 92 vs 80. Neither emits native video, so the comparison is about parsing images and documents, not generation.
Speed & latency
Qwen3.8-Max is faster in interactive use: ~55 tok/s with 0.6s TTFT versus ~25 tok/s with 2.0s TTFT (about 2.2× the throughput). For conversational UIs where perceived responsiveness drives retention, that edge is a real product factor even when raw reasoning is lower.
Context: window vs usable recall
Nominal windows are 1M for Qwen3.8-Max and 1.05M for GPT-5.6 Sol. Crucially, the larger nominal window does not win on usable recall: GPT-5.6 Sol advertises 1.05M but Qwen3.8-Max scores higher on effective-context (95 vs 88), i.e. it actually retains more of what it was given.
Price & total cost
Qwen3.8-Max is the cheaper API at $2.5/$7.5 versus GPT-5.6 Sol at $5/$30 per 1M input/output tokens — list input is about 2.0× lower. Cache discounts (Qwen3.8-Max 80% vs GPT-5.6 Sol 50%) shift the effective bill, worked out below.
Chinese vs English
English: Qwen3.8-Max 78 vs GPT-5.6 Sol 92. Chinese: 98 vs 74. For Chinese-language production, Qwen3.8-Max is the stronger pick. Note that non-Chinese models generally require overseas network access for their APIs.
Tool use & ecosystem
Function-calling score: Qwen3.8-Max 88 vs GPT-5.6 Sol 93, so GPT-5.6 Sol has the edge on structured tool use. Fine-tuning is available from Qwen3.8-Max. Factor in existing SDK/plugin familiarity — switching cost often outweighs a few-point tool-use gap.
Cost worked example — same workload, real token math
Assume a production workload of 100M input + 30M output tokens per month, with 90% of input tokens served from cache. Figures use public list prices.
