Qwen3.7-Max vs DeepSeek V4
Verdict. Qwen3.7-Max has the higher raw intelligence but is closed and API-only; DeepSeek V4 is open-weight MIT, cheaper, and self-hostable. Capability vs control.

The analysis
Both are the leading Chinese-lab flagships, but they sit on opposite sides of the open-weight line. Qwen3.7-Max posts a top-5 Artificial Analysis Intelligence Index of 56.6 and a documented 35-hour autonomous run — but it is closed-weight, API-only ($2.50/$7.50), with an undisclosed architecture. DeepSeek V4 trails slightly on aggregate (~52) yet ships under MIT as open weights you can self-host, at lower cost.
If your priority is the highest capability-per-dollar via an API and you can live with a closed model, Qwen3.7-Max leads. If you need to own the weights, audit the model, or deploy in a sovereign/air-gapped setting, DeepSeek V4 is the only one of the two that qualifies.
Caveat: several of Qwen3.7-Max’s headline figures (the 35-hour run, some coding evals) are vendor-claimed and pending independent reproduction; it is also a verbose reasoner, so effective cost-per-task runs above the rate card.
Pick Qwen3.7-Max if…
- Highest open-frontier intelligence via API
- Long autonomous tool-loops (35-hour demo)
- Anthropic Messages-compatible harness (Claude Code)
Pick DeepSeek V4 if…
- You need open weights you can self-host (MIT)
- Lower cost and auditable architecture
- Sovereign / air-gapped deployment
Qwen3.7-Max
Alibaba’s closed-weight agent flagship: top-5 intelligence, 1M context, and 35-hour autonomy at half the Western-frontier price.
DeepSeek V4
Open-weight frontier-class coding at one-sixth the price — MIT-licensed, 1M context, self-hostable.
