UltraX: Redefining LLM Data Refinement
UltraX redefines LLM data refinement by introducing function-calling for fine-grained editing, achieving superior performance with fewer training tokens.

How Andrej Karpathy's Software 2.0 Thesis Became Software 3.0
Karpathy's 2017 'Software 2.0' essay predicted that neural networks would absorb entire engineering stacks. His 2026 Sequoia Ascent talk defines a third era, where large language models automate anything humans can verify. Here is how the thesis evolved across nine years and four organizations.
