Clarifai has partnered with Arcee AI to serve as the primary launch partner and hosting provider for Trinity, Arcee’s new family of open-weight foundation models. This collaboration aims to accelerate Arcee’s launch and provide a blueprint for model labs looking to bring their home-trained or open-weight models to market efficiently.
The Trinity models, Trinity Nano (6B) and Trinity Mini (26B), are available through Clarifai’s Compute Orchestration platform, providing developers, startups, and enterprises with access to high-efficiency, U.S.-built open-weight LLMs through an OpenAI-compatible API. A larger third Trinity model is currently under development.
This partnership marks a milestone in the open-weight ecosystem, as a U.S. model lab focused on performance-per-parameter partners with a U.S. infrastructure platform known for delivering high-throughput, low-cost inference at scale.
According to Matt Zeiler, Founder and CEO of Clarifai, Arcee AI is demonstrating the potential of efficient, open-weight U.S. models. He stated that Clarifai’s Compute Orchestration platform is designed to make it fast, reliable, and cost-effective for model builders to deploy their own custom or open-weight LLMs without needing to establish their own inference stack. Zeiler added that Clarifai will continue to be the platform with the best price-performance as more teams develop specialized models.
Arcee AI, an American open-intelligence lab, is dedicated to advancing open-weight models in the U.S. The Trinity models, reflecting this mission, include:
- Trinity Nano (6B / 1B active): Optimized for real-time, on-device, and embedded AI.
- Trinity Mini (26B / 3B active): Tuned for multi-step agent workflows, robust function calling, and long-context use cases.
Both models share features such as 128K context windows for extended multi-turn reasoning, efficient attention mechanisms to reduce memory and compute loads, and high inference efficiency with strong price-performance characteristics.
Mark McQuade, CEO of Arcee AI, stated that the launch of Trinity demonstrates that frontier models can be built quickly with efficient capital and still perform at the highest level. He noted that Arcee AI has trained three open-weight models in just six months, with each release becoming more effective. McQuade added that partnering with Clarifai will accelerate collaborative research and help create the next generation of foundational models.
By launching Trinity on Clarifai, Arcee AI gains a hardened, cost-efficient inference layer designed for custom and open-weight models. Clarifai’s Compute Orchestration platform provides features such as autoscaling, GPU fractioning, spot-aware scheduling, kernel-level performance optimizations, hybrid, multi-cloud, and on-prem flexibility, global availability with enterprise-grade reliability, and OpenAI-compatible endpoints for integration.
Arcee AI’s Trinity Nano and Trinity Mini models are now available on Clarifai, with Playground access, API integration, and compatibility with OpenAI-spec clients and agentic frameworks.
