We’re introducing gpt-oss RL support and the fastest RL inference and lowest VRAM use vs. any implementation. Blog: https://docs.unsloth.ai/new/gpt-oss-reinforcement-learning
- Unsloth now offers the fastest inference (~3x faster), lowest VRAM (50% less) and most context (8x longer) for gpt-oss RL vs. any implementation - with no accuracy loss.
- Since RL on gpt-oss isn't yet vLLM compatible, we...
We're excited to support Vision models for RL and even more memory efficient + faster RL!
Unsloth now supports vision/multimodal RL with Gemma 3, Qwen2.5-VL and other vision models. Due to Unsloth's unique weight sharing and custom kernels, Unsloth makes VL...
We’re excited to introduce Unsloth Flex Attention support for OpenAI gpt-oss training that enables >8× longer context lengths, >50% less VRAM usage and >1.5× faster training compared to all implementations including those using Flash Attention 3 (FA3). Unsloth Flex Attention makes it possible to train with a 60K context length on just 80GB of VRAM for BF16 LoRA. Also:
- You can now ex...
