DeepSeek V3.2
Extremely competitive coding and reasoning benchmarks at a fraction of commercial-API pricing — strong default for cost-sensitive batch workloads.
Open-weight hosting means latency and uptime vary by inference provider (DeepInfra, Fireworks, etc.) — pin a provider or add fallbacks for production SLAs.
GPT-5.4 Mini
Good default for everyday chat, summarization, and lightweight agent steps where GPT-5.4-level reasoning isn't required.
Quality gap widens on long, multi-hop reasoning tasks — needs careful prompt design to avoid silent failures on edge cases.
