TLDR AI

STATE OF LLMS IN LATE 2025

The AI landscape has evolved into a hyper-specialized ecosystem where each model has distinct strengths. The challenges emerging include diminishing returns on scaling, massive energy consumption, and the rise of smaller specialized models. This guide explains the technical foundations that make each model different so developers can choose the right tool for their task. Success now means understanding each model's strengths, testing on specific use cases, routing intelligently, and staying current.

HARVARD ECONOMIST: AI DATA CENTER BOOM POWERS 92% OF US GDP GROWTH, MASKING ECONOMIC STAGNATION

The massive spending on AI data centers is almost single-handedly propping up the US economy. It drove 92% of GDP growth in the first half of this year. The economy could have flatlined with just 0.1% growth without the investment. The surge stems from an escalating AI compute arms race. The spending raises concerns about an unsustainable bubble masking weakness elsewhere.

AI-GENERATED TESTS ARE LYING TO YOU

Developers have shifted to getting AI to generate unit tests over the last year. While this makes everything look good, often, developers are actually just replacing validation with transcription. The more developers automate testing without understanding it, the more they risk turning existing bugs into features. The future of software engineering belongs to those who automate the right things and keep thinking about the rest. AI can amplify good engineering discipline, but it can't replace it.

LESS IS MORE: RECURSIVE REASONING WITH TINY NETWORKS

A single Samsung researcher developed Tiny Recursive Model, which uses a 2-layer network that recursively improves its answer up to 16 times. It outperforms DeepSeek R1 and o3-mini-high on ARC-AGI by 10% to 30% despite having 0.01% of the parameters. The approach simplifies the Hierarchical Reasoning Model by eliminating complex mathematical theorems and dual-network hierarchies, and suggests that smaller networks with deeper recursion generalize better than larger ones without recursion.

MEET LLMC: BEATING ALL COMPRESSION WITH LLMS

LLMc uses AI models to compress natural language. It serves as a high-capacity probabilistic reference system, enabling compression based on token prediction and rank encoding. It efficiently identifies high-likelihood token sequences and encodes them into a compact form using LLMs' in-context capabilities. Benchmarks show that LLMc outperforms traditional compressors such as ZIP and LZMA across a range of datasets.
