LLMs Do Not Always Need Readable Language

LLMs may not need human-style language. i.e. future AI systems might save context space by using dense model-readable messages instead of long normal prose. The authors propose BabelTele, a compressed writing style that can mix abbreviations, symbols, fragments from different languages, and unusual structure. To a capable language model, it can still carry enough structure to answer questions, preserve memory, and pass information between agents. The point is that human readability, natural-language fluency, and machine recoverability are separable properties. Human prose carries redundancy because humans need rhythm, grammar, context, and reassurance. Models trained on huge symbolic mixtures may not need all of that scaffolding every time. In the paper’s strongest result, BabelTele keeps about 99.5% semantic fidelity while shrinking text to 27.9% of its original length. ---- – arxiv. org/abs/2606.19857 Title: "LLMs Do Not Always Need Readable Language"
