Closed-Source API
An AI model service model in which the vendor provides only an API interface. The model runs on the vendor's side, users cannot access model weights, and they depend on the vendor's hosted service and ongoing maintenance.
Timeline (last 90 days)
When a researcher's work depends on closed-source APIs, once a request is judged to violate the usage policy, the research chain is immediately interrupted and is difficult to reproduce or migrate.
Closed-source API users can only control input and output, and cannot touch optimization switches inside the inference engine such as scheduling strategies, memory allocation and operator fusion.
An overfitted harness is the prompt engineering, post-processing logic, and evaluation pipeline that a team customizes around a specific closed-source API, which may completely break down when the model vendor updates its version or adjusts its parameters.
