GoKawiilOpenAI unveils Decisions API, resembling TypeSafe AI's Jev classifier model
At OpenAI's Dev Day, CEO Sam Altman introduced a new 'Decisions API' that lets developers give the company's Luna model a predefined set of options to choose from, such as image categories or agent behaviors, returning fast, low-cost outputs. The tool appears similar to Jev, a classifier model released earlier this month by TypeSafe AI for software automation tasks. OpenAI's API is currently in limited preview, and TypeSafe did not respond to requests for comment on the similarities.
GoKawiil's interpretation of the reporting above, not reported fact.
The move suggests OpenAI sees demand for faster, cheaper alternatives to full LLM calls for routine classification and decision tasks embedded in software agents. TypeSafe CEO Diogo Almeida suggested on X that OpenAI's interest could validate his company's 'System One' approach to fast, intuitive AI decisions as opposed to slower deliberate reasoning models. This could intensify competition among startups building lightweight classifier tools designed to complement or reduce reliance on larger LLMs.
- OpenAI's new Decisions API lets Luna choose among predefined options quickly and cheaply.
- The API closely resembles TypeSafe AI's Jev model, released earlier this month for software automation.
- TypeSafe's CEO suggested the similarity validates demand for fast, low-cost 'System One' style AI decision-making tools.
