Which should you pick?怎么选
- Want Kling 4.0 now? As of Oct 15 it's on Kling's own site, MCP and CLI. Runway's plans still list Kling 3.0.
- Need predictable costs? Kling hasn't published Kling 4.0 credit costs yet; Runway publishes per-model credit rates (e.g. Gen-4.5 at 12 credits/sec).
- Building a product on top of video generation? Kling's API has no Kling 4.0 yet (listed as coming soon); its current API covers Kling 3.0 and older models.
- Prices change often; always confirm on the live pricing pages linked below.
