The Fastest Path To Super Intelligence
Summary
This episode introduces Poetic, a company developing recursively self-improving AI reasoning harnesses designed to make large language models perform better than their base versions. The discussion highlights how Poetic's approach offers a cost-effective and faster alternative to traditional fine-tuning, allowing startups to achieve state-of-the-art performance without the massive expense of training new models.
Key Points
- Poetic offers recursively self-improving AI reasoning harnesses that enable LLMs to continuously enhance their own intelligence, a concept considered the "holy grail" of AI development.
- Poetic's method is significantly faster and cheaper than traditional approaches that require training new LLMs from scratch, which costs millions and takes months, often becoming obsolete with new model releases.
- Startups using Poetic gain a competitive advantage by always having systems that outperform out-of-the-box models, without the risk of their investments being invalidated by rapid AI advancements.
- Poetic's system generates specialized agents or "harnesses" that outperform the underlying language models for specific tasks, providing a cost-effective performance boost.
- Poetic has demonstrated impressive results on benchmarks like ArcGi v2 and Humanity's Last Exam, significantly surpassing existing state-of-the-art models with much lower costs.
- The company's approach is described as a new paradigm, distinct from Reinforcement Learning (RL), focusing on automated optimization of reasoning strategies and data for LLMs.
- Poetic's technology automates the creation of these complex harnesses, which typically involve intricate combinations of code, prompts, and data, saving significant human effort and expertise.
- The recursive self-improvement mechanism of Poetic allows it to adapt and optimize for new LLM releases, ensuring continued performance gains without requiring costly retraining.
- Poetic views frontier models not as competitors but as foundational layers upon which their "stilts" can be built, allowing them to achieve superior performance.
- The company emphasizes that their approach optimizes the entire agent or its components, including prompts and reasoning strategies, to maximize the utility of LLM calls.
Conclusion
Poetic's approach offers a significant advantage for startups by providing a cost-effective and rapid path to achieving state-of-the-art AI performance, mitigating the risk of obsolescence due to rapid model advancements.
The company's technology revolutionizes how AI systems are built and optimized, moving beyond traditional fine-tuning to a more dynamic and continuously improving model.
The core message for engineers is to actively engage with AI, experiment, and push boundaries, as the pace of change means continuous learning and adaptation are crucial for innovation.

Timeline
Poetic is developing recursively self-improving AI reasoning harnesses for LLMs, aiming to make AI smarter through its own improvement.
Poetic's core insight is enabling recursive self-improvement much faster and cheaper than existing methods, avoiding the need to train new LLMs from scratch which costs hundreds of millions and takes months.
Poetic's systems ensure users will always have an AI that is better than the out-of-the-box models, a key advantage for startups navigating rapid AI progress.
Poetic's system automatically generates specialized systems that outperform underlying language models for particular problems without massive expense.
Poetic's system demonstrated its capability by surpassing Gemini 3 DeepThink on the ArcGi v2 benchmark shortly after its release, achieving higher performance at a lower cost.
Poetic achieved a 55% score on Humanity's Last Exam, outperforming Anthropic's Claude Opus 4.6 and demonstrating the effectiveness of their approach on challenging questions with a sub-six-figure optimization cost.
Poetic's harnesses are code, prompts, and data built on LLMs, generated automatically by their recursive self-improving meta-system to solve hard problems.
Poetic's approach represents a new paradigm beyond traditional RL, with its own S-curve of improvement tied to both the meta-system and underlying models.
Poetic's meta-system automates tasks like context stuffing and example generation, offloading the data understanding and failure mode identification to the AI itself.
The most significant performance gains come from sophisticated reasoning strategies encoded in code, rather than just optimized prompts, leading to dramatic improvements.
Startups with difficult problems that have exhausted other solutions are encouraged to sign up for early access on Poetic's website.
