Could you build this?
No Training and running a latent reasoning LLM involves modifying the underlying transformer architecture, training custom latent reasoning projection heads, and writing custom vLLM serving kernels.
What it would actually take: This project involves training a continuous latent reasoning recurrent block/head on top of a quantized large foundation model (DeepSeek) using PyTorch and custom CUDA kernels. It requires implementing custom inference logic in a forked vLLM engine to handle latent state caching instead of standard auto-regressive token emissions. Doing this necessitates deep ML research capabilities, access to multi-GPU training infrastructure, and specialized kernel optimization skills.
Discussion
20 comments analyzed.
Competitors mentioned: CoLaR paper approaches, Anthropic's chain-of-thought methods, vLLM
Concerns raised: Loss of interpretability and chain-of-thought monitorability for safety/alignment, Models may think differently in latent space than generated reasoning shows, Overtinking on simple prompts in ablation tests, No frontier labs currently using latent reasoning despite claims of feasibility, Code and writing may be AI-generated without proper human verification
Feature requests: Ability to decode chain of thought from latent representation, Tunable thinking effort without polluting token IO, Control knob to keep thinking until model is confident it's done, Latent-reasoning version of frontier models as optional variant
