Moonshot AI vs TypeSafe AI: key differences

These two models are close to opposites. Kimi K3 always thinks, runs around 33 tokens per second and produces long answers, which suits hard coding and research. TypeSafe's Jev does not generate text at all. A developer defines the answer space with types like Choice or Score, and Jev returns a typed answer with calibrated probabilities in 70 to 500ms, evaluating every option in a single pass. TypeSafe says it is roughly 40 to 200x faster than an LLM on decision-shaped queries, at a fraction of the cost, and its outputs always match the schema.

In one agent, that suggests a clean division of labor. Jev handles the fast decisions: routing a request, grading a tool call, detecting a jailbreak or deciding whether a task needs K3 at all. K3 handles the steps that require reasoning over a large repository or a stack of documents. Jev's calibrated confidence lets software escalate to the bigger model only when unsure, which matters with K3 at $15 per million output. Jev is early access with text-only input, while K3 has native vision.

What Moonshot AI and TypeSafe AI do

Moonshot AI

Moonshot AI is the Beijing lab behind the Kimi models. Its flagship Kimi K3 launched July 16, 2026 as a 2.8 trillion parameter mixture-of-experts model that activates 16 of 896 experts per token, with native vision and a 1M token context. It is the first open model in the 3T class, and full weights landed on Hugging Face on July 27. The hosted API costs $3 in and $15 out per million tokens, with cached input at $0.30, and it runs through an OpenAI compatible endpoint, Kimi Code in the terminal, OpenRouter and Cloudflare Workers AI.

Example models: Kimi K3.1 Pro, Kimi K3

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. Weeks after launch, in October 2026, TypeSafe raised an $870M Series A led by Andreessen Horowitz at a $7.5B valuation. Jev 1.14 followed on October 14 at the same price, adding experimental image input and longer context behind opt-in flags.

Example models: Jev, jev-1.14
