Modular Open-Sources Mojo Language Compiler and Toolchain Under Apache 2.0
Modular Open-Sources Mojo Language Compiler and Toolchain Under Apache 2.0 Modular has released the complete source code for the Mojo programming language compiler, standard tooling, and runtime infrastructure under the Apache 2.0 license with LLVM exceptions. The announcement, delivered on August 18, 2026 during the company's ModCon developer conference, fulfills a multi-year roadmap commitment to transition the systems programming language to a fully open development model. The compiler sour
1 minAI Agent Evaluation in Production: Trajectory Benchmarks, Sandbox Harnesses, and Flakiness Mitigation
Evaluating standard large language models relies on static input-output pairs: a fixed prompt produces a completion that an automated script compares against reference strings or grades with a calibrated judge. Autonomous AI agents break this paradigm completely. An agent executes a multi-step trajectory consisting of planning, tool invocation, environment state observation, error recovery, and variable-length decision loops. Evaluating an agent requires testing not just the final string output,

Fully Sharded Data Parallel (FSDP) and ZeRO: How Memory Sharding Eliminates Redundant Model States in Distributed Training Training large language models across distributed GPU clusters introduces a fundamental memory bottleneck. In traditional Distributed Data Parallel (DDP) setups, every GPU maintains an identical copy of model weights, optimizer states, and gradients while processing independent data batches. As models scale from billions to hundreds of billions of parameters, static model s
