OpenAI vs TypeSafe AI: key differences
TypeSafe AI was founded by Diogo Almeida, who co-invented RLHF and InstructGPT at OpenAI, and its product is a deliberate departure from GPT-style generation. Jev does not produce text or code. A developer defines the answer space with primitives like Choice, Score and a true-or-false type, and Jev returns a typed answer plus calibrated probabilities and a confidence score. It evaluates every option in one pass, so calls finish in 70 to 500ms end to end. TypeSafe puts it at roughly 40 to 200x the speed of an LLM on decision-shaped queries, at a fraction of the cost.
That makes Jev a candidate for work many teams now send to a cheap GPT tier like Luna: routing tickets, scoring leads, classifying intent or picking which model gets a prompt. Because outputs always match the schema, Jev cannot return a value outside the options. For anything open-ended, OpenAI remains the tool, from chat to computer use on GPT-6 Astra. Jev is also early access, with text-only input and a new programming model to learn. A common setup would put Jev in front of GPT as the router and guardrail.
What OpenAI and TypeSafe AI do
OpenAI
OpenAI runs the most widely adopted closed-model API. Its October 2026 lineup has GPT-6 Astra at the top for computer use, coding and long agentic runs, priced at $10 in and $50 out per million tokens. Below it sit GPT-6.1 Sol, the default for coding, research and computer use at $2 in and $10 out, and GPT-6 Luna for high-volume jobs at $0.10 in and $0.50 out. All three carry a 1.05M token context window with up to 128K output.
Example models: GPT-6 Astra, GPT-6.1 Sol, GPT-6 Luna

TypeSafe AI
TypeSafe AI builds decision models instead of text generators. Founder Diogo Almeida co-invented RLHF and InstructGPT at OpenAI and later worked at Google Brain; his co-founders are Erik Gafni and Sasha Sheng. After two years in stealth the company launched on September 15, 2026 with a $40M seed round led by DCVC and released its first System One Model, Jev, in early access. The name nods to Kahneman's fast System 1 thinking, and the model is built for machines to call, not people to chat with.
Example models: Jev, jev-1.13
