## How they compare

TypeSafe's Jev picks from developer-defined options and returns a typed answer with calibrated probabilities in 70 to 500ms. It costs $0.042 per million input tokens with output free, takes text only with 32K context, and is in early access. Boundless serves models that generate text and code, such as DeepSeek V4 Flash at $0.04 in and $0.21 out per million tokens and GLM-5.3 at $1.12 in and $3.52 out, most with 1M context, plus resold GPT and Claude models. Its API works with OpenAI and Anthropic SDKs.

Pick TypeSafe when the answer is one of a fixed set, like routing a ticket or flagging a jailbreak, and the system needs to know how sure the model is. Pick Boundless when the agent has to write text or code, or when a team wants engineers to run a reserved deployment against latency targets. An agent can call Jev for its branch decisions and a Boundless model for everything it writes.

## 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.

### Boundless

Boundless launched in September 2026 as an inference partner for AI-native startups. It sells two things. The Model API serves pre-tuned models on shared capacity, billed per token from prepaid credits with a budget per API key. Tailored inference reserves capacity for one customer, and Boundless engineers pick the model on the customer’s own evals, tune precision, batching, caching, speculative decoding and parallelism, then run the deployment against uptime, throughput and latency targets written into the contract. A free two-week evaluation tests those targets on real traffic against the customer’s current provider first.
