This open-source 400B-parameter model thinks before responding to handle long and complex prompts. It ranks just behind Claude Opus 4.6 on PinchBench and costs 96% less (Apache 2.0 license)
Trinity-Large-Thinking is a high-performance, open-source large language model featuring a massive 400-billion parameter architecture. Positioned within the Developer and Data Science category, it is specifically engineered to 'think' before responding, a process intended to enhance its ability to navigate complex, multi-layered prompts and logical challenges.
6, while offering a significantly lower cost profile. 0, it provides developers with the freedom to deploy, modify, and scale the model without the constraints of closed-source APIs.
Potential users should carefully evaluate their infrastructure, as a 400B model requires substantial computational power and specialized hardware to operate efficiently. This tool is ideal for those prioritizing reasoning depth and open-source flexibility over the immediate response times of smaller, less complex models.

Take advantage of Anthropic’s AI model—more reliable, more honest, and four times less likely to overlook its own errors. Its fast mode delivers up to 2.5 times more tokens per second (at the same API rate as the previous version)
This Mixture-of-Experts model, with approximately 1 trillion parameters, features a 1M-token context, virtually infinite Engram memory, and multimodal capabilities for text, images, and video. It aims to achieve performance scores comparable to Claude Opus while remaining significantly more affordable (to be released under the Apache 2.0 license)
OpenAI's most powerful frontier model directly controls your computer, processes 1 million tokens, and reasons about very long tasks. It is claimed to reduce errors by 33% and significantly improve code and document analysis
A Google AI model capable of handling complex tasks involving text, images, audio, or video. It can summarize lengthy sources, analyze data, and assist in coding end-to-end interfaces
Tackle time-consuming and complex tasks by letting AI plan, use tools, check its work, and see tasks through to completion with minimal supervision. This model significantly improves coding, the use of virtual machines, online research, and knowledge work tasks

Trinity-Large-Thinking utilizes a reasoning phase before generating output, which is designed to improve accuracy for complex prompts. This often results in a longer time-to-first-token compared to standard models. Users should evaluate if the depth of reasoning justifies the additional latency for their specific use case, particularly in applications requiring real-time interaction or high-speed throughput.
