POST https://dashscope-intl.aliyuncs.com/compatible-mode/v1/chat/completions
Qwen 3.5 Flash is one of the cheapest reasoning-capable models available — at 0.06/0.24 per MTok with 1M context, it’s significantly cheaper than DeepSeek V4 Flash while still supporting full reasoning modes. Great for high-volume tasks where cost matters. Getting an API Key

Reasoning modes
The brain icon next to the message box controls how this model reasons. Click it to cycle through the modes the selected model supports. Two separate ideas combine here:
Thinking — whether the model reasons
- Off — the model answers immediately. Fastest and cheapest; ideal for simple, direct tasks.
- On — the model first works through the problem in a dedicated reasoning pass before replying. Slower and uses more tokens, but markedly more accurate on multi-step, logical, or ambiguous tasks.
Effort — how hard it thinks
Only effort-capable models expose this; it applies once thinking is on.
- High — standard reasoning depth. The right default for most agentic work.
- Max — the model reasons longer and deeper for the hardest problems. More tokens and latency in exchange for higher quality on complex work.
| State | Colour | Meaning |
|---|
| Off | gray | Thinking off — direct answer |
| On | blue | Thinking on — no effort control |
| High | purple | Thinking on, standard effort |
| Max | orange | Thinking on, maximum effort |
Cost Comparison
Qwen spans a wide price range, competing at every tier:
| Tier | Model | Input / Output (per MTok) | Comparable To |
|---|
| Ultra-cheap | qwen3.5-flash | 0.06/0.24 | Cheaper than DeepSeek V4 Flash |
| Budget | qwen3.7-plus | 0.40/1.60 | MiMo V2.5 Pro range |
| Mid-range | qwen3.7-max | 2.50/7.50 | Between Kimi K2.6 and Anthropic |
| Legacy | qwen-max | 1.60/6.40 | MiniMax M3 range |
Start with Qwen 3.5 Flash for high-volume tasks, Qwen 3.7 Plus for general agentic work, or Qwen 3.7 Max when you need frontier reasoning. The dedicated Qwen3 Coder Plus model is a good pick for code-heavy workflows at a budget price.
