OneTriangle
● Identity checkedCode · Vendor site 2026-10-04
OneTriangle builds a KV cache-aware inference engine that prefills on a smaller model and decodes on a larger one. By transferring key-value cache between models, it targets lower prefill cost and faster first responses on long inputs without sacrificing decode quality when pairs pass quality gates.

Is OneTriangle right for you?
A good fit for
Teams running multi-model LLM inference who want to cut redundant prefill work on long prompts.
Before you choose
Cache transfer only applies to vetted model pairs; ordinary prefill runs when a pair fails quality or latency gates.
Smaller prefill, larger decode
OneTriangle optimizes inference by running prefill on a compact model, transferring KV cache into a larger decoder, and falling back to standard prefill when a pair does not meet held-out quality checks.
