This tutorial demonstrates how to implement an intelligent routing layer using NadirClaw to optimize Large Language Model (LLM) costs. The system classifies prompts into simple or complex tiers locally before selecting the most appropriate model, such as switching between Gemini Flash and Pro versions. It covers installation, local classification testing via CLI, visualizing decision boundaries through centroid-based similarity scores, running a proxy server for live routing, and calculating estimated cost savings compared to using high-end models exclusively.

The article demonstrates how the earlier EDEN quantization method outperforms its "successor" TurboQuant by utilizing an analytically optimized scale factor for superior accuracy and bias correction.
* EDEN outperforms newer TurboQuant algorithms.
* Optimal scaling is a key differentiator.
* EDEN-biased minimizes reconstruction error (MSE).
* EDEN-unbiased ensures highly accurate estimation.
* Superior efficiency at low bit-widths.
* Ideal for LLM and KV cache optimization.

This research presents a scalable method for extracting linear representations of concepts within large-scale AI models, including language, vision-language, and reasoning models. By mapping these internal representations, the authors demonstrate how to steer model behavior to mitigate misalignment, expose vulnerabilities, and enhance capabilities beyond traditional prompting. The study also shows that these concept representations are transferable across languages and can be combined for multi-concept steering. Additionally, the approach provides a superior method for monitoring misaligned content like hallucinations and toxicity compared to direct output judgment models.
Key points:
- Scalable extraction of linear concept representations
- Model steering for safety and capability enhancement
- Cross-language transferability and multi-concept steering
- Monitoring of hallucinations and toxic content via internal states

A specialized implementation of a 25,000-parameter decoder-only transformer designed to run on an unmodified Commodore 64. Written in hand-coded 6502 assembly, the model features real multi-head causal self-attention, RMSNorm, and softmax, achieving functionality similar to modern LLM architectures despite the extreme hardware constraints of a 1 MHz processor.
Key technical details include:
- Uses int8 quantized parameters with per-tensor shift scaling.
- Implements fixed-point arithmetic (Q8.8) for activations.
- Features a 128-token BPE vocabulary and a 20-token context window.
- Includes tools for quantization-aware training (QAT) to ensure model accuracy on integer hardware.
- Capable of running on real C64 hardware or emulators like VICE, with performance averaging 60 seconds per token.
