Anthropic 收购 Stainless 的主要目的是获取人才并调整战略，随后逐步停止了包括 SDK 生成器在内的所有托管产品，影响了数百家依赖该服务的公司。

许多人认为这一关闭时机不当，损害了开发者的信任，尤其是 Stainless 一直被视为初创公司和 API 提供商的可靠合作伙伴。对风险投资支持的初创公司被收购后关闭的做法普遍存在批评，批评者认为这种模式会破坏已有价值，并给被迫迁移的用户留下技术债务。

也有观点认为这只是典型的人才收购（acqui-hire）：Stainless 员工从交易中获益，SDK 生成器的输出仍归客户所有，且提供了自助迁移的路径。但另一部分人将此举视为反竞争行为，尤其是在 OpenAI 依赖 Stainless 提供其主要 SDK 库的背景下，消除该服务可能对竞争对手造成的影响大于对 Anthropic 本身的伤害。

普遍的担忧是，AI 公司凭借巨额资本收购并扼杀关键基础工具。 Anthropic 在尚未盈利的情况下投入数十亿美元，这被一些人视为 AGI 炒作周期中可能存在的问题或欺诈风险。此次收购也符合 AI 实验室把开发者工具整合进"围墙花园"、限制第三方使用的平台化趋势，从而引发对未来建立依赖后价格上涨和供应受限的担忧。

开源工具（例如 Microsoft 的 TypeSpec）以及竞争替代品（如 APIMatic 、 Fern）被强调为更可持续的选择，不少公司已经开始构建内置解决方案以避免供应商锁定。关于 AI 是否能真正替代专业工具的争论也在持续，批评者指出，讽刺的是 Anthropic 需要收购 Stainless，而不是直接用自己的模型去生成 SDK 。

总体讨论反映了对当前 AI 商业模式可持续性的深刻怀疑。许多人预测，一旦某些公司确立市场主导地位，那些现在靠补贴维持的服务最终会被削弱。尽管有人认可 Stainless 背后的人才和质量，主要情绪仍是对大型 AI 公司收购并降级广泛使用服务的失望和怀疑。用风险投资资金收购基础工具然后关闭或限制访问的做法，加剧了对围墙花园和长期供应商锁定的担忧，也扩大了对整个 AI 行业商业可行性和 AI 真正替代专业人才能力的疑问。 - Anthropic is acquiring Stainless primarily for talent and strategic positioning, winding down all hosted products including the SDK generator, which disrupts hundreds of companies relying on the service.

- The shutdown is seen by many as tone-deaf and damaging to developer goodwill, especially since Stainless positioned itself as a dependable partner for startups and API providers.

- There is widespread cynicism about VC-backed startups being acquired and shut down, with critics arguing this pattern destroys value and creates technical debt for users forced to migrate.

- Some defend the acquisition as a standard acquihire, noting that Stainless employees benefit from the deal and that the SDK generator's output remains owned by customers, with a self-service transition path available.

- The move is viewed by some as anti-competitive, particularly because OpenAI relies on Stainless for its main SDK libraries, and eliminating the service could harm competitors more than Anthropic itself.

- Broader concerns are raised about AI companies using monopoly money to acquire and kill foundational tools, with Anthropic spending billions despite not being profitable, signaling potential fraud in the AGI hype cycle.

- The acquisition fits a pattern of AI labs consolidating developer tooling into walled gardens, restricting usage to their own platforms and raising fears of future price increases once dependence is established.

- Alternatives like open-source tools (e.g., Microsoft's TypeSpec) and competitors (e.g., APIMatic, Fern) are highlighted as more sustainable options, with some companies already choosing to build in-house solutions to avoid vendor lock-in.

- There is debate over whether AI can truly replace the need for specialized tooling, with critics pointing out the irony that Anthropic had to acquire Stainless rather than simply generating SDKs with its own models.

- The discussion reflects deep skepticism about the sustainability of current AI business models, with many predicting that subsidized services will eventually be enshittified once market dominance is achieved.

The conversation reveals a fundamental tension between the promise of AI-driven efficiency and the reality of corporate consolidation in the developer tools space. While some acknowledge the talent and quality behind Stainless, the dominant sentiment is one of frustration and distrust toward large AI companies acquiring and deprecating widely-used services. The pattern of using venture capital to fund acquisitions of foundational tools, only to shut them down or restrict access, fuels concerns about walled gardens and long-term vendor lock-in. This skepticism extends to the broader AI industry, where massive spending by unprofitable companies raises questions about the sustainability of current business models and the true capabilities of AI to replace specialized human expertise.
