v0.16.0
Axolotl v0.16.0 Release Notes We’re very excited to share this new packed release. We had ~80 new commits since v0.15.0 (March 6, 2026). Highlights Async GRPO — Asynchronous Reinforcement Learning Training ( #3486 ) Full support for asynchronous Group Relative Policy Optimization with vLLM integration. Includes async data producer with replay buffer, streaming partial-batch training, native LoRA weight sync to vLLM, and FP8 compatibility. Supports multi-GPU via FSDP1/FSDP2 and DeepSpeed ZeRO-3. Achieves up to 58% faster step times (1.59s/step vs 3.79s baseline on Qwen2-0.5B). Optimization Step Time Improvement Baseline 3.79s — + Batched weight sync 2.52s 34% faster + Liger kernel fusion 2.01s 47% faster + Streaming partial batch 1.79s 53% faster + Element chunking + re-roll fix (500 steps)

Show HN: MicroSafe-RL – Sub-microsecond safety layer for Edge AI 1.18µs latency
I built MicroSafe-RL to solve the "Hardware Drift" problem in Reinforcement Learning. When RL agents move from simulation to real hardware, they often encounter unknown states and destroy expensive parts. Key specs: 1.18µs latency (85 cycles on STM32 @ 72MHz) 20 bytes of RAM (no malloc) Model-free: It adapts to mechanical wear-and-tear using EMA/MAD stats. Includes a Python Auto-Tuner to generate C++ parameters from 2 mins of telemetry.

Google Gemma 4: Everything Developers Need to Know
Google dropped Gemma 4 on April 2, 2026, A full generational jump in what open models can do at their parameter range and the first time in the Gemma family's history that one ships under Apache 2.0, meaning commercial use without permission-seeking. Some context: since Gemma's first generation, developers have downloaded the models over 400 million times and built more than 100,000 variants. Four Models, One Family Gemma 4 is a family of four, each aimed at a different point in the hardware spectrum. E2B : Effective 2 billion active parameters. Runs on smartphones, Raspberry Pi, Jetson Orin Nano. 128K context window. Handles images, video, and audio. Built for battery and memory efficiency. E4B : Effective 4 billion active parameters. Same hardware targets, higher reasoning quality. About
