Super excited for our open-weights release on Thursday...
A new LLM that is almost FREE but massively improves on long-running personal agentic loops
Yes, it will be available via the API and be better than DeepSeek Flash.
Sneak peek at our NYC conference tomorrow! 🚀
00:15 - The right way to prompt Claude
33:21 - What makes Claude act dumber on your code
01:33:39 - How Anthropic use Claude every day
02:50:56 - The fix that makes Claude way smarter This
4-hour Anthropic free course replaces about 10 paid engineering courses.
Watch it today, then read the step-by-step guide on building loops below.
50 AI tools that are actually FREE:
No trials.
No monthly credits.
No subscription required.
Most can run locally or self-hosted.
The best part?
A lot of these can run entirely on your own machine.
No subscription.
No waiting for monthly credits.
Your data can stay local.
You really don’t need an expensive AI stack to start experimenting.
Some of these tools can optionally connect to paid APIs or models. If you want to keep usage at $0, pair them with local/open models instead.
A few examples are explicitly designed for local/offline or self-hosted use: Open WebUI can run entirely offline, AnythingLLM offers a free local desktop experience with no account required, Cline supports local models, and Fooocus is free/offline software.

Stop reading attention is all you need.
Transformers (LLMs) clearly explained with visuals:
- Real GPT-2 visualizer
- tokens to embeddings
- 12 attention heads (Q, K, V, scale, mask, softmax)
- multi-head Q/K/V
- residual + MLP
- next-token probabilities
That’s the difference between reading about transformers and seeing one think.

Andrej Karpathy’s 1-hour Stanford lecture on AI engineering is one of the best explanations I’ve seen of how AI systems actually work.
The progression is simple:
10% → LLM
30% → Prompt
50% → Agent
70% → Loop
100% → Graph
The key takeaway:
AI engineering isn’t just about writing better prompts.
It’s about building systems around models — giving them context, memory, tools, feedback loops, and data flows.
“Delete everything, keep Graph.”
Definitely worth watching if you’re building with AI agents.

I put together a handbook on how attention works, from the Q/K/V equation up through how it actually runs in modern LLMs.
Self vs. cross-attention, causal masking, multi-head attention, RoPE, KV caching, MHA/MQA/GQA/MLA, FlashAttention, worked through by hand, with citations back to the original papers.
Made it to be the explanation I wish I'd had.
How to Build an AI Agent Complete Roadmap

Andrew Ng just released a free 2-hour course on complete Harness Engineering
How to go from one prompt to a reliable system of agents that can run, test, and improve themselves:
09:14 - Build your first agent from scratch
33:11 - Master agent loops
1:02:46 - Turn loops into reliable workflows
1:30:15 - Build agents that improve their own work
1:49:05 - Run the complete system without supervision
Model → Harness → Reliable Software
Most agent tutorials stop once the model can call a tool
This one shows you how to build the infrastructure around it within the first 20 minutes
Most people are still prompting one agent at a time
Andrew Ng is already teaching the layer above:
Harnesses that give agents context, tools, tests, and feedback
Watch this brilliant course and build the harness
