Which should you choose?
Choose DeepSeek if price matters most — it starts at Free, which is friendlier for teams watching burn. Both AI Agents tools ship core features, so the cost delta often decides it for small teams and solo operators.
Choose StepFun if you want the most established option — it has raised Undisclosed, suggesting more runway for enterprise features, support, and long-term roadmap. For mission-critical workflows or larger teams, that stability often outweighs a lower monthly price.
