AGI Advance: Weekly AI & AGI Insights (Aug 12, 2025)

This week, we’ve been focused on advanced reasoning in code, and how frontier labs are rethinking the way models learn to think like engineers, not just autocomplete code.

Here’s what we’re learning:

• Chain-of-thought isn’t just for math: Our internal dataset includes over 700k Python samples paired with explicit reasoning traces, moving models beyond token matching to structured problem-solving. Fine-tuning Qwen2.5 (7B–32B) on this data set a new SOTA on LiveCodeBench and CodeContests, beating comparable SFT-only models.
• Incorrect answers are useful: Surprisingly, the best results came from training on both correct and incorrect solutions, suggesting that failure cases, when structured well, still drive learning through distillation and generalization.
• The best coders reason before they code: Across simulated code challenges, models that succeeded showed causal reasoning, debugging steps, and metacognitive reflection before submitting code. We're now designing model assessments that weight reasoning quality alongside final answers.

As models scale, structured code reasoning, not just completion, will unlock reliability in software agents. We're not just sampling code; we’re teaching models how to think before they type.

🗣️Jonathan Siddharth, Founder & CEO:
“Frontier models need frontier data—and that starts with human intelligence, not just internet scale.”

In a recent podcast interview, Jonathan unpacked why saturated benchmarks, synthetic evals, and static datasets are no longer enough. As models grow more capable, meaningful improvement now depends on post-training—where PhDs, Olympiad-level coders, and domain experts work together to uncover model gaps and generate structured, verifiable feedback.

From supervised prompts to RL environments powered by cloned enterprise UIs, the new frontier isn’t just more tokens, it’s higher-quality, human-aligned data.

• Achieving 10,000x Training Data Reduction with High-Fidelity Labels
  Google researchers developed a scalable curation pipeline that reduces fine-tuning data requirements from 100,000 to fewer than 500 examples, while improving alignment with expert reviewers by up to 65%. The system uses active learning, clustering, and expert-labeled disagreement pairs to pinpoint the most informative training samples. In experiments with Gemini Nano models, the 3.25B variant trained on curated data outperformed crowd-labeled baselines using three orders of magnitude less data, with Cohen’s Kappa rising from 0.36 to 0.56 and 0.23 to 0.38 across tasks. This method is especially promising for dynamic, high-ambiguity domains like ad safety and policy enforcement.
• On the Generalization of SFT: A Reinforcement Learning Perspective with Reward Rectification
  This paper proposes Dynamic Fine-Tuning (DFT), a one-line code change that dramatically improves LLM generalization by correcting the implicit, ill-posed reward structure in standard Supervised Fine-Tuning (SFT). Unlike SFT, which often overfits due to unstable gradient updates, DFT reweights the loss based on token probabilities, yielding more stable learning and broader generalization. On five math reasoning benchmarks (e.g., AMC23, Olympiad Bench), DFT outperformed SFT by up to 18.75 points, and even surpassed advanced RL methods like PPO and GRPO in offline settings. DFT also showed faster convergence, better sample efficiency, and stronger robustness on challenging datasets, positioning it as a practical alternative to complex RL pipelines.
• AudioGen-Omni: A Unified Multimodal Diffusion Transformer for Video-Synchronized Audio, Speech, and Song Generation
  AudioGen-Omni introduces a unified multimodal diffusion transformer capable of generating high-quality audio, speech, and song synchronized with video and/or text inputs. By integrating novel components like a lyrics-transcription encoder, joint attention with phase-aligned positional embeddings, and multimodal conditioning, the model achieves strong semantic alignment and lip-sync accuracy. On the VGGSound benchmark, it outperforms prior methods with a 21.5 Inception Score, 0.45s DeSync, and 1.91s inference time for 8s audio. It also outperforms other video-to-speech models on LRS3 with UTMOS 3.98, DNSMOS 3.78, and a 17.6% WER, demonstrating robust speech quality and alignment.

Turing will be at two major AI conferences in the coming months—join us to discuss the future of AGI:

• COLM 2025 [Montreal, Canada | Oct 7 – 10]
  The Conference on Language Modeling (COLM) aims to create a community of researchers with expertise in different disciplines, focused on understanding, improving, and critiquing the development of LM technology.
• NeurIPS 2025
  [Mexico City | Nov 30 – Dec 5]
  [San Diego Convention Center | Dec 2 – 7]
  The Neural Information Processing Systems Foundation is a non-profit that promotes research in AI and ML by organizing a leading annual conference focused on ethical, diverse, and interdisciplinary collaboration.
