Pure linear attention keeps a full key-value state with mostly static decay, while Mamba-2 adds selective, input-dependent scalar gating per step and larger per-head states.

(Bell Labs / NYU), popularized by LeNet-5 | history | beginner | https://ieeexplore.ieee.org/document/726791 | When was CNN introduced, and by whom? | CNNs were introduced by Kunihiko Fukushima's Neocognitron in 1980 and perfected into the modern template by Yann LeCun's group at Bell Labs, whose 1998 paper Gradient-Based Learning Applied to Document Recognition described LeNet-5 for reading checks and zip codes.

(Universite de Montreal, for Neural Machine Translation) | limitations | intermediate | https://arxiv.org/abs/1406.1078 | What are the limitations or drawbacks of GRU? | With only two gates and no separate cell state, GRUs can be less expressive than LSTMs on tasks that need very long or highly structured memory. Like all classic recurrent units they train sequentially and cannot parallelize across time, which blocks large-scale pretraining. Empirical differences between GRU and LSTM a... | ||

ai-arch-000007 | Griffin | State Space & Hybrid Models | 2,024 | Soham De et al. (Google DeepMind) | technical | advanced | https://arxiv.org/abs/2402.19427 | Why does Griffin extrapolate to long contexts better than attention? | Full attention relies on positional schemes that often degrade beyond trained lengths, and its cache grows unboundedly. Griffin's recurrent layers have no length-dependent components, and its local attention windows are fixed-size, so sequence length affects only the number of steps, not the state machinery. Consequent... | ||

It extrapolates to contexts longer than trained and scales cleanly across model sizes. The RG-LRU gate design is wid... | ||

As with all pure SSMs, lossy state compression limits exact long-range recall, keeping hybrids necessary for knowledge-heavy chat. The framework's benefits also assume mo... | ||

CNNs use pooling and striding to gain invariance, discarding precise pose information as features ascend, which makes them robust but can conflate different configurations. CapsNets keep pose vectors and bind parts to wholes via routing-by-agree... | CNN | |

Introduced in February 2024 in the paper RecurrentGating for Linear-Time Sequence Modeling, Griffin matched strong Transfo... | ||

Improved DDPM in 2021 added learned variances and classifier guidance, and classifier-free guidance in 2022 made conditional generation controllable. DDIM enabled ... | ||

This bounds attention logits, preventing the attention-entropy spikes that destabilize large-model training, replacing Gemma 2's logit soft-capping, which required cust... | ||

Original LDM used a U-Net; DiT swapped in a Transformer over the same latents, gaining scaling-law behavior and better compute-quality curves. Modern systems combine both: VAE latents pl... | Latent Diffusion | |

What is it, in simple terms? | Gemini Diffusion is Google DeepMind's experimental text-diffusion model, unveiled at Google I/O in May 2025, that generates text by iteratively denoising an entire response from noise rather than predicting tokens sequentially. Positioned as a research preview, it demonstrated frontier-lab commitment to parallel text g... | ||
ai-arch-000024 | MiniMax-01 | State Space & Hybrid Models | 2,025 | MiniMax (Chinese AI lab) | technical | advanced | https://arxiv.org/abs/2501.08313 | Why keep one softmax-attention layer in eight? | Linear attention's fixed state cannot store verbatim keys and values for millions of tokens, so tasks requiring exact lookup suffer without an escape hatch. Periodic softmax layers provide exact-access checkpoints, and ablations in MiniMax's reports showed that even a small fraction restores retrieval behavior with neg... | ||

Methodology
- Curated knowledge base: every architecture has a hand-authored fact sheet (definition, mechanism, innovations, advantages, limitations, applications, history, current status, and 3 deep technical Q&As) grounded in the original papers and technical reports.
- Template diversity: 3–7 instruction phrasings per question type, combined with deterministic seeded selection of supplementary facts, yielding varied but factually consistent answers.
- Freshness: "current status" entries reflect the state of the field as of late 2025 / early 2026, including hybrid SSM adoption, diffusion LLM commercialization, and reasoning-model paradigms.
- Quality control: zero duplicate (instruction, output) pairs, zero duplicate instructions, ASCII-safe text, and minimum answer length validation.
Usage
from datasets import load_dataset
ds = load_dataset("0xRavenBlack/ai-architecture-types")
example = ds["train"][0]
Or directly with pandas / pyarrow:
import pandas as pd
df = pd.read_parquet("data/train-00000-of-00001.parquet")
print(df[df["difficulty"] == "advanced"].sample(3)[["instruction", "output"]])
Training with the Alpaca-style prompt format:
def format_example(row):
return f"### Instruction:\n{row['instruction']}\n\n### Response:\n{row['output']}"
Limitations & Considerations
- Point-in-time knowledge: "current status" entries reflect late-2025/early-2026 landscape; benchmark rankings of frontier models evolve quickly.
- Scope: rows focus on architecture concepts and design trade-offs, not code-level implementation details.
- Perspective: answers summarize mainstream expert consensus from primary sources; contested claims are flagged where relevant (e.g., KAN vs. MLP replication debates).
- Language: English only.
- Not suitable as a sole source for safety-critical or legal advice about model licensing.
