Five things from this week's HN and dev.to worth bookmarking if you're building with AI APIs and shipping static sites on a tight budget.
DeepSeek makes the V4 Pro discount permanent
DeepSeek announced this week that their previously temporary V4 Pro price cut is now permanent. The cost gap between DeepSeek and GPT-4o-class APIs at the high-throughput end is now large enough that it's worth benchmarking against your current setup.
I'm running Claude Haiku 4.5 for content generation across three directory sites — structured JSON output at scale. My reason for not switching isn't cost; Haiku produces reliable, schema-conformant output even under pressure, and the caching story (via cache_control: ephemeral on system prompts) cuts the effective cost significantly once you have the caching setup dialed in. But if I were starting fresh today, DeepSeek's permanent pricing would make it a serious contender for batch ETL workloads. The race to the bottom on API pricing is real, and permanent discounts are harder to walk back than promotional ones.
