## How they compare

TypeSafe AI's Jev models answer decision-shaped questions. 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, at $0.042 per million input tokens with free output. It generates no text or code and has a 32K context. OpenScale, a Y Combinator-backed API out of Singapore, serves DeepSeek V4.1 Flash at $0.06 in, $0.003 cached and $0.24 out per million tokens under a 50% promotion, at 200+ tokens per second, with a fast tier at about twice the speed. It speaks the Anthropic, OpenAI Responses and Chat Completions formats with a 1M token context window.

The two fit together more than they compete. Jev works as a router, guardrail or smart if-statement inside a workflow, and OpenScale serves the model that writes the text or code. Pick Jev when the output is a decision and confidence matters, and OpenScale when you need a cheap general LLM.

## What each one does

### 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.

### OpenScale

OpenScale is a Y Combinator-backed inference API built by LatentSpace and run out of Singapore. It sells open models behind one endpoint that speaks Chat Completions, the OpenAI Responses API and Anthropic Messages, so Claude Code, Codex, OpenCode, Cline, GitHub Copilot, Zed and other coding agents can point at it with a base URL and key. Its public catalog today is DeepSeek V4.1 Flash in two versions, standard and fast, both with a 1M token context window and up to 384K output tokens.
