Small AI models gain reasoning abilities through memory techniques

• Smaller models like a 150-million-parameter system can now perform complex reasoning tasks by using temporary memory to store and compress information during problem-solving.
• OpenAI's GPT-5.6 Sol retains reasoning steps between queries, showing that how a model organizes its thinking matters as much as the model's raw size.
• Research indicates memory and compression strategies are becoming as important as simply making models larger, creating an alternative path to improve AI capabilities.

Small models using latent-space reasoning with temporary memory, like BDH-CQ's 150M model, and OpenAI's GPT-5.6 Sol with retained reasoning, show that memory and compaction strategy have become first-class capability multipliers. The newsletter emphasizes this as a separate scaling path from pure model size.
