Your sovereign, private TF K3 Optimised

TF K3 Optimised is ToothFairyAI's efficiency-tuned flagship: we took the frontier K3-class architecture (2.8T-parameter multimodal MoE with native vision, 1M-token context and interleaved thinking) and optimised its reasoning behaviour to produce substantially shorter thinking traces — roughly 40% fewer reasoning tokens — while maintaining comparable quality across our evaluations. The result is frontier-level coding, research and agentic performance at a markedly lower cost and time-to-answer, with vision and function calling fully supported. A reasoning model in the ultra tier, served on ToothFairyAI's AU, EU and US endpoints — private by default, billed in US dollars per million tokens at the published rates below. No training on your data, no vendor lock-in.
