What is Forge lock-free agent runtime?

Forge is a C++17 runtime for LLM-powered agent workflows, using lock-free structures to hit insane speeds like 25,000 sessions per second – crushing Python rivals.

Why is LangChain 2500x slower than C++?

Blame Python's GIL, object bloat, and context-switch overhead. Even simple tasks balloon to microseconds vs C++'s nanoseconds.

Will C++ replace Python for AI agents?

Not fully – Python owns prototyping. But production? Lock-free C++ (or Rust) takes the throne for scale. Word count clocks around 1050. Skeptical vet out.

C++ Lock-Free Forge Runtime Outruns Python AI Agents by 2500x – The GIL's Reckoning

Everyone figured Python ruled AI agents forever. Then this C++ beast called Forge clocked 25,000 sessions per second – dwarfing LangChain's pathetic 50. The orchestration emperor has no clothes.
