Stainless Secures Adoption by Anthropic, OpenAI and Meta for SDK Generation
Anthropic, OpenAI and Meta rely on Stainless to generate consistent and reliable SDKs, as LLMs struggle with the precision required for this task.
At a glance
Anthropic, OpenAI and Meta use Stainless, a dedicated tool, to generate their SDKs. Large language models have proven inconsistent for this task, leading the three AI labs to adopt specialized SDK generation software.
What changed
Industry practice has converged on Stainless as the preferred solution for producing production-grade SDKs. The tool ensures output consistency and reliability where general-purpose LLMs fall short.
Why it matters
Operationally, teams reduce time spent on manual SDK maintenance and debugging. Commercially, faster and more stable client libraries accelerate partner and customer integration cycles. From a compliance perspective, predictable SDK behavior supports reproducible audit trails and lowers governance risk in regulated environments.
Key details
SDKs must deliver uniform interfaces and error handling across releases. LLMs frequently produce variations in structure, naming and edge-case logic, making them unsuitable for unassisted SDK generation. Stainless addresses these limitations through purpose-built generation logic.
