<h2>TitanRL</h2>
<p>TorchTitan now does reinforcement learning! Many RL stacks keep separate training and inference implementations of the model. Architecture changes have to stay aligned across both, and when a run goes sideways it is hard to tell whether the culprit is your reward, your algorithm, or the two copie…

<h3>Agentic RL at scale</h3>
<p>TitanRL supports what you need to train agentic workloads. Rollouts run asynchronously – training and generation each scale with multiple forms of parallelism.</p>
<p>We tested it on several workloads, as seen below, demonstrating that it can perform stable training on MoEs and dense models, for hundreds of steps, on tasks that require long context, code execution, compaction, harness, self-play, etc.</p>

<p>TorchTitan shipped massive performance improvements for MoE models in the past year – around three focus areas: faster kernels for higher computer utilization, maximizing communication compute overlap, and fine grained control of memory.</p>
<p><strong>local_compile</strong> brings the benefits of native <code>torch.compile</code> without committing to full-graph or full-block tracing, allowing users to selectively optimize key regions while preserving numerics without maintaining custom kernels.</p>

-<p>Today, to address the growing demand from the developers and research community on Trainium, we are excited to share an even simpler approach to program the chip as a standard PyTorch device, ahead of its open source launch at PyTorch Conference North America on Oct. 20. AWS Trainium is a portfol…
-<p>TorchNeuron supports eager execution for research and debugging including new adaptive eager mode with improved performance, torch.compile for production performance, and the <a href="https://awsdocs-neuron.readthedocs-hosted.com/en/latest/nki/index.html">Neuron Kernel Interface (NKI)</a> for cus…
-<blockquote><p><em>&#8220;PyTorch&#8217;s vision is straightforward: developers should have a consistent experience across hardware platforms. Native support for AWS Trainium expands that choice, enabling researchers and engineers to experiment and iterate using the eager execution and distributed A…
-<h2>Getting started: Easy device switching</h2>
-<p>Getting started is straightforward. Run your code on Trainium using the pointer: <code>.to('neuron')</code>.</p>
-<pre><code class="language-python"># Run a training loop on Trainium
-model = MyModel().to('neuron') # the only change
-optimizer = torch.optim.AdamW(model.parameters())
-for batch in dataloader:
- optimizer.zero_grad()
- loss = criterion(model(batch), targets)
- loss.backward()
- optimizer.step()
-</code></pre>
-<p>Modern code written against torch.accelerator, PyTorch&#8217;s recommended device-agnostic API, runs unmodified. A compiled model needs the Neuron backend named, once with <code>torch.compiler.set_default_backend("neuron")</code>, after which <code>torch.compile(model)</code> takes it, or per cal…
-<pre><code class="language-python"># Run a compiled training loop on Trainium
-torch.compiler.set_default_backend("neuron") # call once, before any compile
-model = MyModel().to('neuron')
-model.compile() # no backend argument
-optimizer = torch.optim.AdamW(model.parameters())

-for batch in dataloader:
- optimizer.zero_grad()
- loss = criterion(model(batch), targets)
- loss.backward()
- optimizer.step()
-</code></pre>
-<h2>Capabilities</h2>
-<p>TorchNeuron registers Trainium through PrivateUse1, PyTorch&#8217;s official extension point for custom hardware, so the standard APIs work as written: <code>torch.nn</code>, <code>torch.tensor</code>, <code>torch.autocast</code>, <code>torch.distributed</code>, and <code>torch.profiler</code> al…

-<h3>Eager</h3>
-<p>Eager runs operations immediately, so Python control flow, prints, and breakpoints all work with no compile or trace step. This is the mode for research and debugging. Eager mode dispatches operations individually. Executed directly, each operation compiles its own Neuron Executable File Format (…
-<h3>torch.compile</h3>
-<p><code>torch.compile(model, backend="neuron")</code> captures the model into a graph the Neuron compiler optimizes, and is the mode for stable, high-performance models moving to production. torch.compile can be used to optimize the whole or part of the model and works seamlessly with eager mode. F…
-<p>The Neuron inference stacks are built on the same <code>torch.compile</code> support in TorchNeuron. vLLM Neuron is a plugin to vLLM and serves LLMs; vLLM Omni Neuron is a plugin to vLLM Omni and serves diffusion models for image and video generation.</p>
-<h3>Ops and dtypes</h3>
-<p>Broad aten operator coverage for ops seen across text, multimodal and vision language, image and video generation and understanding, state space models, and world models. Models can use BF16, FP32, and FP16, with integer and boolean types, and <code>torch.autocast</code> and mixed precision code …
-<h3>Distributed APIs</h3>
-<p>Distributed inference and training can use the standard PyTorch APIs and the high-level parallelism modules compose with your model as written: DDP, FSDP2, SimpleFSDP, tensor parallelism, and pipeline parallelism, along with common compositions like FSDP2 with tensor parallelism, ZeRO that are es…
-<h3>Streams and Events</h3>
-<p>Torch streams and events are supported natively. <code>torch_neuronx.Stream</code> and <code>torch_neuronx.Event</code> map PyTorch&#8217;s stream semantics onto Trainium&#8217;s hardware queues. Within a stream, data movement and computation stay in order automatically. Separate streams carry no…
-<h3>Neuron Kernel Interface (NKI)</h3>
-<p>The <a href="https://awsdocs-neuron.readthedocs-hosted.com/en/latest/nki/index.html">Neuron Kernel Interface (NKI)</a> lets researchers and developers develop, optimize, and execute custom operators for both eager and torch.compile. Researchers can prototype ideas that require low level hardware …
