C++
A general-purpose programming language widely used in systems programming, competitive programming, and high-performance computing. C++ is known for fast execution speed and a powerful Standard Template Library (STL), making it the dominant language in competitive programming environments.
Core Facts
On pure computation tasks, Python can be 50–100 times slower than C++.
The header of DeepInfer's LLM class file states 'Derived from vLLM, Modified by DeepSeek', indicating it is built on vLLM and also references SGLang and TensorRT-LLM.
The concept of zero-cost abstraction originates from a principle proposed by Bjarne Stroustrup, the creator of C++.
Timeline (last 90 days)
Many games are written in C++, involving virtual function tables, multiple inheritance, template instantiation and exception handling, and the runtime structures these constructs leave behind after compilation are very costly to reconstruct.
The C++ standard belongs to WG 21 within SC 22 (Programming Languages) under ISO/IEC JTC 1.
The C++ standard follows a three-year release cadence (such as C++20, C++23, C++26), and features that miss the window usually have to wait more than three years.
In C++ asynchronous RPC, if a completion callback may still run after cancellation, freeing request state too early introduces use-after-free vulnerabilities.
The engineer gave the example of a tail-latency problem in a C++ search service system: median latency was normal, but p99 was terrible.
Jai's compile-time execution differs from C++'s constexpr or template instantiation: Jai is not limited to pure functions or specific syntactic structures.
A pragmatic path for rewriting a commercial engine in Jai may be a hybrid architecture: writing new modules in Jai and coexisting with existing C++ code through the C ABI, rather than a full rewrite.
Jai is still in a stage of continuous development, and its standard library and third-party ecosystem are far less rich than those of C++ or Rust.
Jai's FFI bindings are not zero-cost: C++ classes, templates, exceptions, and name mangling cannot be mapped directly, and a C wrapper layer or manually maintained binding declarations are usually needed.
The uploader's recommended safe path is to choose either "Java + large models" or "C++ + large models"; learning large-model application development can get you started in about three months of spare time.
