Knowledge distillation is a model-compression and capability-transfer technique in which a powerful teacher model provides training signals for a smaller student model.

Instead of requiring the student to rediscover every useful behaviour from raw internet-scale pretraining data, the student learns from the teacher’s outputs, probability distributions, internal representations, reasoning demonstrations or preferences.

A distilled model can therefore become:

• Faster at inference
• Less expensive to operate
• Smaller in memory
• Easier to deploy on limited hardware
• More specialised for a particular task
• More consistent than the original general-purpose model for a narrow workflow

However, an important distinction must be made:

The exact internal process used to train current proprietary Claude models is not publicly disclosed in full.

Anthropic publishes model reports, safety research and selected training information, but its public materials do not expose Claude’s weights, token logits, hidden states, training datasets or the complete teacher–student training recipe. Therefore, when people discuss “distilling Claude,” they may be referring to two different things:

1. Authorised distillation within an official platform, such as Amazon Bedrock’s documented Claude Sonnet-to-Haiku distillation workflow.
2. Black-box behavioural distillation, where permitted Claude outputs are collected and used to fine-tune another model.

Anthropic and AWS have publicly described an authorised workflow in which Claude 3.5 Sonnet generates synthetic training data, Claude 3 Haiku is trained and evaluated using that data, and the resulting distilled model is hosted for inference. This is primarily output-based behavioural distillation rather than traditional access to Claude’s internal logits or hidden layers.

Twenty-two thousand five hundred and eighty. That is roughly how many GPT-2-scale models (≈124M parameters) fit inside Kimi K3 (≈2.8T parameters, 2026). Scale mattered—but it is not the whole story.

A parallel evolution happened inside the architecture itself:

AI models gradually changed from systems that repeatedly search every previous token into systems that maintain, update, erase, and selectively retrieve structured internal memories.

This article combines that memory-systems interpretation with the concrete architectural worklog 22580: From GPT2 to Kimi3, Explained by ali (@waterloo_intern), including the original diagrams, plus the research path from full softmax attention → linear attention → DeltaNet → Gated DeltaNet → Kimi Delta Attention → Kimi Linear / Kimi K3.

An LLM architecture defines how a model converts language into numbers, moves information between tokens, stores short-term contextual memory, transforms representations through neural layers, predicts or generates tokens, and scales parameters and computation.

Most modern language models belong to one or more of these families:

• Recurrent architectures: RNN, LSTM, GRU and RWKV
• Encoder-only Transformers: BERT-style models
• Decoder-only Transformers: GPT, Llama and Mistral-style models
• Encoder–decoder Transformers: T5 and BART-style models
• Sparse Mixture-of-Experts models
• Local, sparse and linear-attention models
• Retention and delta-rule architectures
• State-space models such as Mamba
• Convolutional sequence models such as Hyena
• Hybrid attention–recurrent architectures
• Diffusion language models
• Multimodal language models
• Retrieval-augmented language-model systems
