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
Excellent general-purpose reasoning and broad world knowledge, with strong performance on coding, math, and multi-modal (image + file) inputs.
Output tokens are priced well above input tokens, so verbose responses dominate cost — tight max-token limits and prompt caching matter.
