Pricing of the Qwen1.5-14B
Qwen1.5-14B, Alibaba Cloud's 14 billion parameter dense transformer model from the 2024 Qwen1.5 series (base and chat variants), is open-source under Apache 2.0 license with no model licensing or download fees via Hugging Face. As a beta precursor to Qwen2, it supports stable 32K context length across multilingual tasks (100+ languages) and runs quantized on consumer GPUs like RTX 4070/4090 (~$0.40-0.80/hour cloud equivalents via RunPod), processing 40K+ tokens/minute for chat, code generation, and reasoning workloads.
Hosted inference follows standard 13B pricing tiers: Together AI/Fireworks charge $0.30 input/$0.60 output per million tokens (batch/cached 50% off, blended ~$0.45), Hugging Face Endpoints $0.80-1.60/hour T4/A10G (~$0.20/1M requests with autoscaling), Alibaba Cloud DashScope ~$0.35/$0.70. AWQ/GGUF quantization variants optimize further via Cloudflare Workers/Ollama (4-bit <20GB VRAM), yielding 60-80% savings for production deployment.
Competitive with Llama 2 13B on MMLU/HumanEval via SwiGLU activation and group query attention, Qwen1.5-14B remains efficient 2026 choice for bilingual apps balancing performance and cost at ~8% frontier LLM rates.
