Frontier AI lab building System One Models — machine-native, typed decisions with calibrated confidence for software to act on, not chat.
TypeSafe AI is a San Francisco frontier AI lab, founded in 2024 by former OpenAI researcher Diogo Almeida with Erik Gafni and Sasha Sheng, that emerged from stealth on 2026-09-15 with about $40 million in seed funding led by DCVC — a round Forbes reports valued the company at $200 million, citing a person familiar with the deal. Rather than generating text, its System One Models return typed decisions with calibrated probabilities and confidence scores that software can act on directly, so a business can automate outputs above a confidence threshold and route the rest to people. The first public model, Jev, is in waitlisted early access; the company claims sub-100-millisecond responses, published pricing of $42 per billion input tokens, and up to two orders of magnitude lower cost and latency than frontier LLMs on decision-shaped workloads, and it argues that RLHF-trained chat models are structurally overconfident and therefore need humans in the loop. Almeida, who worked on the instruction-following research behind ChatGPT, says most intelligence should eventually run quietly inside software; the company was part of the 2024 AWS Generative AI Accelerator before launch.

Growth
Came out of about two years of stealth on 2026-09-15 with a $40M DCVC-led seed reported at a $200M valuation and its first model, Jev, in early access. Pitch is a new model class for automation rather than chat: typed, calibrated decisions at roughly two orders of magnitude lower latency and cost than frontier LLMs on decision-shaped tasks, with insurance underwriting cited by Forbes as an example workload. Team is in-person in San Francisco (Embarcadero) with staff drawn from OpenAI, Google Brain, Meta/FAIR, Stripe, Airbnb, Plaid and Docker.

Jev — first public System One Model, in waitlisted early access since 2026-09-15: takes unstructured state plus a predefined schema of questions and returns typed decisions with calibrated probabilities and confidence scores, all outputs generated in parallel rather than token by token
System One Models — the model class, trained with the company's Reinforcement Learning for Calibrated Decisions (RLCD) instead of RLHF; outputs are schema-constrained so type errors are impossible and no free text is generated
Published pricing of $0.042 per million input tokens ($42 per billion) with output tokens free; company-measured end-to-end latency of 70–500 ms and, on its own workflow evals, up to 193.6x faster and 444.6x cheaper than frontier LLMs on System One tasks
Developer surface: console and playground at console.typesafe.ai, docs at docs.typesafe.ai, public workflow-evals site (evals.typesafe.ai) and an open-source System One adapter that constrains ordinary LLMs to the same decision API
