optimumai 0.5.0

Unlock the math behind AI — run any operation with explain=True for a step-by-step trace, terminal visualization, and the intuition of why AI uses it.

OptimumAI

Unlock the math behind AI.

Every mathematical operation in modern AI — from a dot product to a full attention block — can be run with explain=True to produce a step-by-step computation trace, a terminal visualization, and the intuition for why AI actually uses it.

The same code runs fast in production or teaches you exactly what it's doing. micrograd shows you scalar backprop; EpyNN walks you through MLPs — OptimumAI gives you a single, traceable API that runs the whole way from a · b up to softmax(QKᵀ/√dₖ)·V.

from optimumai import Vector

Vector([1, 2, 3]).dot(Vector([4, 5, 6]), explain=True)

Install

pip install optimumai

Optional extras:

pip install "optimumai[llm]"   # LLM tutor (Q&A over concepts)
pip install "optimumai[viz]"   # extra plotting backends

Quickstart — Python

from optimumai import Vector, Matrix, softmax, Attention

# Linear algebra
Vector([1, 2, 3]).cosine_similarity(Vector([2, 4, 6]), explain=True)   # → 1.0
Matrix([[1, 2], [3, 4]]).matmul(Matrix([[5, 6], [7, 8]]), explain=True)

# Probability
softmax([2.0, 1.0, 0.1], temperature=0.5, explain=True)

# Transformers — the headline
Attention(d_k=4).forward(Q, K, V, explain=True)

Every explain=True call returns the numeric result and prints the trace, so it drops straight into notebooks, scripts, and tests. Prefer the data over the print-out? Use the *_trace variants:

trace = Vector([1, 2, 3]).dot_trace(Vector([4, 5, 6]))
trace.result      # 32.0
trace.steps       # [Step(...), Step(...), ...]
trace.why_ai      # ['Similarity between two embedding vectors', ...]

The fundamentals (v0.2)

The same explain=True philosophy now runs all the way down to the atoms of modern AI. Inspired by Karpathy's micrograd/nanoGPT, Yann LeCun's world models, and Anthropic's interpretability research (see PHILOSOPHY.md):

from optimumai import Value, MLP, MultiHeadAttention, JEPA, superposition

# Autograd — a scalar computation graph that differentiates itself (micrograd)
a = Value(2.0, label="a"); b = Value(-3.0, label="b")
L = (a * b).tanh(); L.label = "L"
L.backprop(explain=True)          # watch the chain rule flow backwards

# Neural net — real backprop, trained by gradient descent
from optimumai.neural_networks import train_demo
train_demo(steps=150).render("intermediate")   # loss falls to ~0

# Transformers — multi-head attention with a causal mask (the GPT decoder)
MultiHeadAttention.demo().render("engineer")

# World models — LeCun's JEPA: predict in latent space, not pixels
JEPA.demo().render("engineer")    # energy = ‖predicted embedding − target embedding‖²

# Interpretability — Anthropic's superposition: why neurons are polysemantic
superposition(n_features=5, n_neurons=2, explain=True)

Quickstart — CLI

optimumai algebra dot "[1,2,3]" "[4,5,6]"
optimumai softmax "[2,1,0.1]" --temperature 0.5
optimumai attention --demo --level engineer
optimumai backprop                    # chain rule through a scalar graph
optimumai train --steps 150           # train a tiny MLP, watch loss fall
optimumai jepa --demo                 # LeCun's world-model energy
optimumai superposition               # Anthropic's polysemantic neurons
optimumai learn                       # list every topic (31 across 10 tracks)
optimumai learn transformer --level researcher

Learn it as a course (v0.3)

OptimumAI isn't just a library — it's a first-principles AI learning path you can walk one step at a time, with your progress tracked across sessions.

optimumai course              # the full path, grouped by track, with ✓/○ progress
optimumai learn dot           # run a lesson — it's marked complete automatically
optimumai progress            # a progress bar + what to learn next
optimumai dashboard           # a Streamlit dashboard to browse + track visually
optimumai ask "why LayerNorm after attention?"   # optional LLM tutor

The lessons build on each other — linear algebra → calculus & autograd → optimization & neural nets → transformers → applied AI (embeddings, RAG, diffusion) → world models & interpretability — each one a runnable, explained Trace. From Python:

from optimumai import COURSE, ProgressTracker

for lesson in COURSE:
    print(lesson.track, lesson.id, "—", lesson.summary)

COURSE.get("rag").run("engineer")        # retrieval-augmented generation, traced
ProgressTracker().mark_complete("rag")   # track your progress

Install the extras you want:

pip install "optimumai[dashboard]"   # Streamlit progress dashboard
pip install "optimumai[llm]"         # LLM tutor (set OPTIMUMAI_API_KEY)
pip install "optimumai[all]"         # everything

Give it your own input (v0.5)

Stop watching demos — feed OptimumAI your numbers, text, and equations and watch them flow:

optimumai repl                              # interactive session (arrow keys w/ [repl] extra)
optimumai trace-text "why is the sky blue"  # your words → tokens → transformer → next token
optimumai algebra dot -i                    # prompts you for the vectors
optimumai compare relu gelu --input "[-2,-1,0,1,2]"
optimumai sweep softmax --values "[0.25,0.5,1,2]"    # watch temperature sharpen the distribution
optimumai diff "x**3 + 2*x" --at 3          # symbolic derivative of YOUR equation (→ 29)

from optimumai import TextPipeline, compare, differentiate

TextPipeline("attention is all you need", layers=2).forward(explain=True)
compare("relu", "gelu", input=[-2, -1, 0, 1, 2], explain=True)
differentiate("sin(x) * x**2", at=1.0, explain=True)   # needs optimumai[symbolic]

Foundations of the stack (v0.4)

Beyond the math, OptimumAI now explains the systems modern AI runs on — the same explain=True treatment for the frameworks and hardware:

optimumai learn tensors           # rank, shape, broadcasting
optimumai learn integration       # trapezoid & Monte Carlo (expectations are integrals)
optimumai learn pytorch           # what torch.autograd does under the hood
optimumai learn jax               # grad / jit / vmap / pytrees
optimumai learn cuda_matmul       # naive vs tiled matmul + memory coalescing
optimumai kvcache --seq-len 8192  # why context length eats VRAM (MHA vs GQA vs MQA)
optimumai vram --params 70        # VRAM budget to train a 70B model

from optimumai import kv_cache_size, vram_estimate, integrate

kv_cache_size(n_layers=32, n_heads=32, head_dim=128, seq_len=4096)  # bytes
vram_estimate(params_billions=7, training=True)                      # GB
integrate(lambda x: x**2, 0, 1, method="monte_carlo")                # ≈ 1/3

Explain levels

The same math, revealed for four audiences (--level on the CLI, level= in Python):

Level	Adds
beginner	The steps and plain-English "why"
intermediate	Per-step detail notes (default)
engineer	Intermediate values + complexity
researcher	Everything

Roadmap

v0.1 — the spine: algebra → probability → attention, plus the tracer, CLI, and terminal visualization.

v0.2 ✅ — the fundamentals: a micrograd-style autograd engine, calculus, SGD/Adam, neural networks with real backprop, multi-head attention + causal mask

• positional encoding + a full transformer block, LeCun's JEPA world model, and Anthropic-style superposition. See PHILOSOPHY.md.

v0.3 ✅ — the learning path: a structured Course with progress tracking, a Streamlit dashboard, embeddings, a RAG pipeline trace, diffusion schedules, and an optional LLM tutor (optimumai[llm]).

v0.4 ✅ — foundations of the stack: tensors & numerical integration, PyTorch & JAX internals (autograd, grad/jit/vmap, pytrees), and the systems layer — the CUDA execution & memory model, tiled matmul kernels + coalescing, the KV cache (MHA/GQA/MQA), and a VRAM budget calculator. The course now spans 28 lessons across 9 tracks.

v0.5 ✅ — interactive input: a REPL, trace-text (your words → transformer), --interactive prompts, op compare, parameter sweep, and symbolic diff of your own equations. The course now spans 31 lessons across 10 tracks.

v0.6 (next) — visualization: matplotlib 2D/3D → PNG. Activation curves, attention heatmaps, embedding scatter, and a 3D loss landscape with the gradient-descent trajectory carved across it.

v0.7 (after) — the circuit: render any Value/Trace as an interactive computation graph (HTML + Graphviz + terminal) with data and gradients lighting up the wires — Karpathy's draw_dot meets Anthropic's circuits.
