Our pick

For most workloads, choose Qwen 3 Coder.

2.0× the context window — better for long documents and agents
89% faster throughput — matters for streaming UX and voice agents

Choose DeepSeek V3.5 instead if: Roughly GPT-4o-class quality at roughly 90% off. Tradeoff is region availability (Chinese provider) and slower output throughput than Western frontier tiers.
