New Open-Source AI Sharpens Its Own Reasoning Abilities
In a significant stride for the open-source artificial intelligence community, the San Francisco-based startup Deep Cogito has released Cogito v2, a new family of AI models designed to sharpen their own reasoning abilities.[1] The release features four powerful hybrid reasoning models, all under an open-source license, signaling a potential shift in how AI systems achieve and refine intelligence.[1][2] This development introduces a novel approach to AI self-improvement, moving beyond simply processing vast amounts of data to a more nuanced form of internalizing and learning from its own thought processes.[3] The implications of this release are substantial, potentially accelerating innovation and expanding access to high-performance AI, while challenging the dominance of proprietary systems developed by larger, more established technology giants.[4][5]
At the core of Cogito v2's innovation is a technique called Iterated Distillation and Amplification (IDA).[6][7] This method represents a departure from traditional training paradigms where an AI's intelligence is often limited by the quality of human-curated data or the capabilities of a larger "overseer" model.[7] Instead, IDA allows the models to engage in a form of self-reflection; they run through reasoning chains during their training and then distill the insights gained from these processes back into their own core parameters.[3] This creates a self-improvement loop where the model's intelligence can scale more directly with the computational resources applied to it.[7] The goal is to cultivate a stronger "intuition," enabling the model to anticipate the most effective path to a solution without needing to exhaustively search every possibility.[1] This efficiency has tangible benefits, with Deep Cogito reporting that its models can achieve strong results with reasoning chains that are 60% shorter than those of competitors like Deepseek R1.[1][3]
The Cogito v2 family consists of four models: two mid-sized versions with 70B and 109B parameters, and two large-scale versions at 405B and 671B parameters.[1] The largest, a 671B Mixture-of-Experts (MoE) model, is positioned as one of the most powerful open-source AI models available.[1] MoE models are notable for their efficiency; they use a sparse routing mechanism that activates only a fraction of the model's parameters—the most relevant "experts"—for any given task.[3] This makes them well-suited for high-performance inference and complex reasoning without the same computational overhead as dense models that activate all their parameters at once.[3] The new models are hybrid reasoning systems, meaning they can either provide a direct, standard LLM response or engage in a more deliberative "thinking" process before answering.[2][8] Deep Cogito has optimized these models for a range of applications including coding, STEM, instruction following, and multilingual tasks.[2][8]
The performance of the Cogito v2 models, according to the company's internal benchmarks, is competitive with some of the leading models in the field. The flagship 671B MoE model reportedly outperforms DeepSeek R1 in reasoning tasks and approaches the performance level of proprietary models like Claude 4 Opus.[1][3] Even in its non-reasoning mode, the model shows significant performance gains, suggesting that the distilled intuition from its training has a broad impact on its overall capabilities.[3] This level of performance is particularly noteworthy given the reported cost-efficiency of the project; Deep Cogito claims to have developed the entire suite of models for less than $3.5 million, a fraction of the investment typically associated with training frontier AI systems.[1] The release of these models under a permissive open-source license further democratizes access to this advanced technology, allowing developers and researchers to build upon, fine-tune, and deploy these powerful tools for their own specific use cases.[4][3]
The launch of Deep Cogito v2 contributes to a broader trend of open-source AI fundamentally reshaping the technology landscape.[9][4] Open-source models promote accessibility, allowing smaller companies and individual researchers to experiment with and build upon cutting-edge AI without prohibitive costs.[10][5] This fosters a more collaborative and transparent ecosystem, where the community can collectively audit, improve, and ensure the safety and fairness of AI systems.[5] The availability of powerful reasoning models like Cogito v2 is particularly significant, as reasoning is a critical component for developing more sophisticated and reliable AI that can handle complex, multi-step problems.[11][12] As AI continues to evolve from pattern recognition to more human-like reasoning, the development of open-source models that can iteratively improve their own thinking processes marks a crucial step toward building more advanced and ultimately more beneficial artificial intelligence.[13][12][7]
