| Key features | - forward_backward() operation for computing loss and accumulating gradients
- optim_step() for updating the adapter
- sample() for generating from current or saved policy
- save_state() to save and resume training state
- Tinker API compatibility
- Separate trainer and sampler resources
- Synchronous and asynchronous RL patterns
- Frozen base model weights with LoRA adapter updates
- Support for open models from Qwen, Google, DeepSeek, Moonshot AI, NVIDIA, and Z.ai
| - Speculative decoding for faster token generation
- Prompt caching for context reuse
- Real-time prompt processing while typing
- Concurrent request batching
- Bit-for-bit identical output verification
- Multi-GPU and multi-backend support (CUDA, Vulkan)
- Vision model support with image encoding
- Mixture-of-experts model support
- RAD-1 automatic draft token generation
- Cross-platform support for Windows and Linux
|

| What makes it different | - Managed training and sampling infrastructure, no setup required
- Tinker-compatible API for easy migration
- Ready-made SFT and RL recipes through Loops cookbook
- Support for vision-language models
| - Exact deterministic inference: all default optimizations preserve bit-for-bit identical output compared to plain decoding
- 4.5× faster performance on editing tasks on small models compared to llama.cpp
- Verifiable reproducibility through receipt system that records all request parameters
- Nine optimization techniques enabled by default with ability to disable each individually
- No dependency on draft models or external selections for speculative decoding
