TL;DR: 大多数 AI 数字人价格对比只看月费,但这会把预录制视频生成器、捆绑式 conversational agent,以及实时 rendering API 混在一起。本文按真实每分钟成本重新归一化比较,把 rendering-only 平台和 bundled stack 分开,并指出很多买家容易忽略的核心成本:云端 GPU rendering。在本文调研的、公开标价的 production-grade real-time avatar API 中,Spatius annual Scale 是最具性价比的公开价格,为 $0.0056/min。

AI 数字人价格对比为什么容易失真

如果你搜索过 “compare pricing for leading AI avatar services”,大概率会看到类似结构:一串工具列表、一张月费表格,以及一个比较模糊的推荐结论。

问题在于,这些工具并不是同一种产品。预录制 avatar video generator、捆绑式 conversational-video platform,以及 rendering-only real-time avatar API 的成本结构完全不同。只看月费,并不能告诉你当 kiosk、tutor、support agent 或 AI companion 每天连续运行数小时时,真实账单会变成什么样。

本文基于截至 2026 年 7 月 4 日可公开获得的 pricing data。公开价格经常变化,购买或发布前仍应再次核对。

  • Rendering-only vs bundled stack:有的平台只对视觉 avatar layer 计费;有的平台同时打包 STT、LLM、TTS、orchestration 和 hosting。
  • Cloud rendering vs on-device rendering:云端渲染会把 GPU 和带宽成本写进每一分钟;端侧渲染会改变 unit economics。
  • Minutes are not always equal:有些产品按 streaming minute 计费,有些按 credits,有些按 generated video second,还有些会有最低消费或起步费用。

Price at a Glance: Production-Grade Platforms

下表把价格列统一到 per-minute 口径。月费只用于说明 tier context;如果 vendor 使用 credit-based 或 non-live usage,表格会展示计算方法,而不是强行做 false apples-to-apples comparison。

核心结论不是每个平台都可以直接互换。真正的结论是:在可以把 live streaming 或 rendering minute 归一化比较的 production-grade real-time avatar API 中,Spatius 拥有最具性价比的公开 per-minute rate。

我们如何归一化价格

  • 如果 vendor 发布 real-time interaction minutes,就直接使用;如果官方 credit rules 有明确映射,则按规则计算。
  • 把 rendering-only 平台和 bundled all-in-one 平台分开。
  • 对 Runway 这类 generated-video 或 credit-based real-time system,除非价格能清晰映射到同一 live-rendering scope,否则归为 adjacent reference。
  • 不纳入没有公开价格的 enterprise quote。
  • 标注分辨率限制和 caveat,避免默认低价一定支持同等输出质量。

两种定价世界:生成式视频 vs 实时互动

Generated video versus real-time interactive avatar billing units: generated minute versus live streaming minute

Runway 这类 generated video platform 很适合制作 finished video assets。Real-time interactive avatar platform 则是通过类似 WebRTC-style real-time media channels 的方式,流式传输一个会实时响应用户的 live digital human。

这个区别很重要:10 秒的 generated clip 和 10 分钟的 customer-service session,在 infrastructure、latency、concurrency 和 cost requirement 上完全不同。

本文重点讨论 real-time interactive avatar pricing。Runway 被纳入,是因为它的 Characters 和 real-time avatar credit model 与 avatar 采购决策相邻。它的 API docs 提供了可计算的 real-time avatar rate,但仍应与 rendering-only avatar API 分开评估。

Deep Dive: Rendering-Only Pricing (BYO AI Stack)

Rendering-only 平台把视觉 avatar layer 与 LLM、TTS、STT 分开计价。对于已经拥有自己 AI stack 的团队,这些平台最接近 apples-to-apples comparison。

Deep Dive: Bundled / Adjacent Pricing

Bundled 和 adjacent 平台通常包含更多 conversational stack,使用 product-line-specific credits,或更接近 generated video。它们适合作为 cost-structure reference,而不是 pure rendering-only rate。

Resolution note:Anam public docs 将 Cara 3 标为 720x480。Cara 4 可在已启用 Cara 4 access 的组织中支持 1152x768 landscape 或 768x1152 portrait,因此不要默认所有 public self-serve setup 都支持更高分辨率。其公开价格是 bundled pricing,不是 pure rendering-only rate。

Resolution note:Beyond Presence pricing 将 High Resolution 标为所有 public plans 的 1080p included capability。即便如此,它仍应放在 bundled/product-line-dependent comparison 中,而不是 pure rendering-only ranking。

可以把 Beyond Presence 当作 bundled/product-line-dependent comparison,而不是 pure rendering-only benchmark。如果比较 fully managed real-time agents,而不是 speech-to-video style usage,应单独确认 managed-agent credit model。

Tavus - premium bundled conversational video

Source: Runway pricing and Runway API pricing, accessed July 5, 2026.

Runway 之所以相关,是因为 Characters 和 gwm1_avatars 与 avatar buying decisions 相邻。其 API docs 将 gwm1_avatars 定价为 2 credits upfront + 2 credits / 6 seconds;按 $0.01/credit 计算,即 startup 后 $0.20/min,另有 $0.02 startup。它适合作为 adjacent reference,而不是 Spatius、Simli、LiveAvatar LITE 的直接 $/min peer。

Runway 应作为 generated-video 和 credit-based API reference 单独评估,不应直接放进 rendering-only peer ranking。

隐藏成本:云端 GPU Rendering

Cloud GPU rendering cost versus Spatius on-device 3DGS rendering cost for live AI avatars

对于高质量 2D cloud-rendered real-time avatars,有意义的 infrastructure comparison 并不是小型 T4 或 L-series card。Production-grade real-time rendering 往往依赖 A100/H100-class infrastructure,加上 bandwidth、scheduling、observability 和 redundancy。

Spatius 的 on-device 3DGS approach 将大部分 rendering cost 从 cloud server off-load 出去。Avatar 的 visual layer 在 client device 本地运行,cloud layer 可以专注于 orchestration、AI services 和 session control。

简言之:2D cloud rendering 会把每一帧都送进 server-side GPU infrastructure。Spatius on-device 3DGS rendering 则把 visual layer 留在本地,这也是 per-minute live-avatar cost 能显著降低的原因。

Custom Avatar Costs Are Setup Costs, Not the Main Unit Economics

Custom avatar creation 很重要,尤其是 branded staff、regional characters 或多个 use-case-specific faces。但它不应混入 recurring live-minute comparison。

对 Spatius 来说,当前 paid-plan framing 是 paid plans 包含 avatar creation quota:Starter 每月 2 个,Builder 每月 4 个,Growth 每月 14 个,Scale 每月 40 个。更大规模的 enterprise avatar creation economics 更适合放到一篇 dedicated custom-avatar pricing article 中单独讨论。

一个平台可以有很低甚至免费的 avatar creation,但如果每个 streaming minute 都很贵,规模化后仍会成本很高。反过来,如果 recurring per-minute rate 很低,即便 setup cost 有一定成本,长期 unit economics 仍可能更有优势。

哪种定价模型更适合你?

如果你已经有自己的 LLM、TTS 和 STT stack

选择 rendering-only。Spatius 是本文调研集合中最具性价比的 public option,尤其是 annual Scale;Simli 是最接近的 rendering-only benchmark。Runway 需要单独评估,因为它的 real-time avatar model 是 credit-based,而不是 rendering-only visual-layer API。

如果你希望整套 conversational-video stack 都由平台处理

比较 Anam、Tavus、Beyond Presence 和 LiveAvatar FULL Mode。它们可能减少 engineering work,但 live-minute economics 明显高于 rendering-only APIs。

如果你制作的是 finished clips,而不是 live interactions

单独评估 Runway。它的 generated-video 和 real-time avatar workflows 都是 credit-based;real-time avatar API 可计算为 startup 后 $0.20/min,另有 $0.02 startup charge,但它不能直接映射到 rendering-only live-avatar overage tables。

FAQ

本文中最具性价比的 real-time AI avatar API 是哪一个?+

在本文比较中,最具性价比的 real-time AI avatar API 是 Spatius annual Scale,价格为 $0.0056/min。按月付费时,Spatius Scale 为 $0.007/min,Starter 为 $0.009/min。Simli 仍是最接近的 rendering-only benchmark,scale 价格约为 ~$0.009/min。

我可以使用自己的 LLM 和 TTS 吗?+

可以。你可以在 Spatius、Simli 等 rendering-only 平台中接入自己的 LLM 和 TTS;在支持的情况下,也可以使用 LiveAvatar LITE-style workflows。Tavus、Anam、Beyond Presence 等 bundled platforms 会包含更多 AI stack,因此更方便,但也更难与 pure rendering APIs 直接比较。

为什么 per-minute cost 比 monthly subscription price 更重要?+

因为 real-time avatars 的规模化成本来自 live usage minutes,而不仅是 seats 或 produced videos。月费看起来低,并不代表高频使用时成本也低;如果 overage rate 很高,avatar 每天运行数小时后成本会迅速上升。

Custom avatar creation 应该计入 per-minute comparison 吗?+

通常不应计入。Custom avatar creation 更像 setup cost,而不是 recurring per-minute comparison 的一部分。预算规划中 custom avatar creation 和 live rendering minutes 都重要,但把它们混成一个 $/min 数字会掩盖真实 unit economics。

Runway 是 real-time avatar APIs 的直接竞品吗?+

Runway 不是 Spatius、Simli 或 LiveAvatar LITE 这类 real-time avatar API 的 clean rendering-only peer。它对 generated character/video workflows 很相关,并公开了 credit-based real-time avatar pricing:使用 API credits 时,startup 后 $0.20/min,另有 $0.02 startup charge。由于 product scope 不同,仍应单独评估。

Bottom Line

问题不只是“哪个平台月费最低?”更好的问题是:“avatar 每次 live 时,我到底在为什么付费?”

对于 production-grade real-time avatars,recurring live-minute cost 才是决定部署是否能规模化的核心杠杆。按这个指标,在本文调研的公开标价 real-time avatar APIs 中,Spatius annual Scale 是最具性价比的选项,价格为 $0.0056/min。

大多数 pricing comparison 会忽略这个区别。它们把 generated video、bundled conversational agents 和 rendering-only live avatars 当成可以互换的 SaaS subscription。但如果你要在有实际规模的场景中部署 real-time interactive avatars,$0.0056/min 和 $0.10/min 的差异就不是一个小的 pricing detail,而是你的 unit economics。
