The system uses task-based model routing, input caching, and prompt compression to optimize spending, with Qwen-Turbo priced at just $0.05 per million tokens for input. In a real case, a small AI chatbot's monthly cost dropped from $218 with GPT-3.5 to $59 after optimization.", "body_md": "Most indie devs and small SaaS waste massive budget on expensive OpenAI/Claude APIs. After 2 months of production testing, I built a cost-saving solution combining Qwen-Turbo and DeepSeek series, cutting total token cost up to 72% without downgrading response quality. This guide includes official raw pricing, task allocation rules and real billing data.\n\n- Raw Official Token Price List (USD / 1M Tokens)\nModel Input Output Core Advantage Best Scenario\nQwen-Turbo $0.05 $0.10 Ultra-low cost, multilingual Classification, short chat, translation\nDeepSeek-V3(Cache Hit) $0.028 $0.28 Cache discount Multi-turn customer chat\nDeepSeek-V3(Normal) $0.14 $0.28 Balance cost&quality General long document summary\nDeepSeek-R1 $0.55 $2.19 Top reasoning Math/code/logic calculation\nCore highlight：Qwen-Turbo input only $0.05 per million tokens, far cheaper than most mainstream open-source cloud APIs.\n- Core Optimization 3 Rules\nTask-based model routing（成本降幅 45%）\nSimple tasks(intention extraction, keyword pull): Qwen-Turbo; daily chat: DeepSeek-V3; complex reasoning: DeepSeek-R1 only.\nMost projects misuse high-end model for trivial requests, which causes overspending.\nEnable input cache（cost cut extra 25%）\nDeepSeek native cache auto-discount repeated context input; our platform adds global request cache to Qwen services, repeat prompts hit cached result directly with zero token cost.\nPrompt compression（save 5%-10% token）\nTrim redundant system prompt, remove useless description in fixed prompt template.\n- Real Case: Small AI Chatbot Monthly Cost Comparison\nOriginal: Full GPT-3.5 → $218/month\nAfter Qwen+DeepSeek optimization → $59/month (↓72%)\nEnding\nIf you want ready-to-use low-price Qwen & DeepSeek API with built-in routing+cache system, check our pricing page: asiatekai.com.
