# Release Notes

## September 3, 2026

## Release 1.6.0

### Summary

This release substantially reduces prediction latency, particularly for short
sequences, and adds the ability to serve requests from several GPUs in one
container.

### Key Features

* **Faster predictions through CUDA graph capture**: The BioNeMo Inference
  Runtime now captures the diffusion module as a CUDA graph. What this removes
  is per-request kernel launch overhead, which is a *fixed* cost rather than a
  proportional one: across the benchmark suite on H100 it takes roughly 7-8
  seconds off every prediction, whatever the input size.

  The speedup therefore looks very different at different sizes, from the same
  change. A 186-residue prediction drops from 10.2 to 2.9 seconds, because
  about 7 of those 10 seconds were launch overhead. A 1869-residue prediction
  drops from 82.5 to 72.5 seconds, the same 10 seconds but now a small
  fraction of the total. Expect a large improvement on short inputs, a modest
  one on long inputs, and on the longest inputs on some SKUs no measurable
  change. Refer to [Performance](/nim/bionemo/openfold3/performance) for measured per-SKU results.
* **Multi-GPU serving**: A container given more than one GPU starts one
  inference process per GPU and serves requests concurrently. Each prediction
  still runs on a single GPU, so this raises throughput rather than lowering
  single-request latency. Refer to
  [Configuration Alternatives](/nim/bionemo/openfold3/configuration-alternatives).
* **Bounded request queue**: When every GPU is busy and the queue is full, the
  NIM returns HTTP 503 rather than accepting work it cannot start. Clients
  should retry after a short delay.
* **Serving your own checkpoint is documented and enforced**: `MODEL_PATH` and
  `MODEL_FILE_NAME` select a checkpoint of the same architecture, fine-tuned
  weights for example. A path that does not resolve is now fatal at startup
  instead of falling back to the shipped checkpoint, which previously made a
  misconfigured mount look like a working one. Refer to
  [Configuration Alternatives](/nim/bionemo/openfold3/configuration-alternatives).
* **Reproducible predictions**: The sampler is seeded per request, so the same
  input returns the same structures on every call. Asking for several diffusion
  samples still returns several different structures within that response. It
  is repeat calls that now agree. `NIM_INFERENCE_SEED=` (empty) restores the
  previous behaviour, where repeat calls varied.
* **Abandoned requests are discarded**: A queued request whose client has
  disconnected is dropped rather than run, and reported as HTTP 499. Previously
  one abandoned long prediction could hold the GPU while every request behind it
  waited for a result nobody would read.
* **Out-of-memory requests are reported, not hidden**: A prediction too large
  for the GPU now returns HTTP 413 naming the residue count, the sample count
  and how much memory was wanted. It previously returned HTTP 500 with
  "Internal server error.", which was indistinguishable from a genuine fault.
* **Updated base image**: The container now builds on CUDA 13.2 and PyTorch
  2.12. This also reduced the container's CVE exposure relative to 1.5.0.
* **Smaller container**: Roughly 11GB to download, down from the previous
  release.

### Notes and Limitations

* Requests are not batched. Concurrency comes from serving one request per GPU;
  a single request never uses more than one GPU.
* All features from release 1.5.0 remain supported.

## June 5, 2026

## Release 1.5.0

### Summary

This release adds support for NVIDIA B300 and GB300 GPUs and introduces a new, fully NVIDIA-optimized inference backend that replaces the previous hybrid implementation.

### Key Features

* **NVIDIA B300**: Added support for NVIDIA B300 GPU
* **NVIDIA GB300**: Added support for NVIDIA GB300 superchip
* **New optimized inference backend**: The NIM now runs on a fully NVIDIA-tuned inference path, delivering faster and more consistent predictions out of the box.

#### Backend Optimizations

The new inference backend introduces custom GPU kernels and graph-level optimizations:

* **New kernels**: Fused Adaptive Layer Norm; DualGemm (sm80, two variants); gated sigmoid (sm80); FlashAttention v2/v3 for Triangle Attention and Attention Pair Bias.
* **Pre-computed masks and buffers**: Pre-computed, left-aligned attention masks feed directly into the new dual-GEMM and attention kernels, with pre-computed buffers for the Pairformer and Diffusion Transformer (DiT) stacks.
* **Lower peak memory**: The confidence module is evaluated in a loop to reduce memory usage.
* **Diffusion Transformer**: Removed the bias computation for Attention Pair Bias, replacing it with three kernels (one reduce, one GEMM, one padding).
* **Optimized query-to-keys path** in the attention computation.

### Notes and Limitations

* The optional PyTorch-only inference mode from earlier releases is no longer available. All requests run on the new optimized backend.
* All features from release 1.4.0 remain supported.

## November 26, 2025

## Release 1.1.0

### Summary

This release adds support for protein structural template inputs for complex structure prediction, and additional GPU hardware.

### New Features

#### Structural Template Support

The NIM now accepts protein structural template inputs (single-chain) to guide structure prediction:

* **Template input**: For each input, protein molecules can include structural templates in CIF format
* **Template guidance**: Templates help constrain and improve structure predictions when experimental or predicted structures are available
* **Multiple templates**: Each protein can have multiple structural templates

#### Additional GPU Support

Support for additional NVIDIA GPU configurations:

* **NVIDIA B200**: High-performance GPU for large-scale structure prediction
* **NVIDIA L40S**: Cost-effective GPU option for production deployments

#### Telemetry Control

**Telemetry control**: NIM Telemetry helps NVIDIA deliver a faster, more reliable experience with greater compatibility across a wide range of environments, while maintaining strict privacy protections and giving users full control.

**Benefits:**

* **Enhances performance and reliability**: Provides anonymous system and NIM-level insights that help NVIDIA identify bottlenecks, tune performance across hardware configurations, and improve runtime stability.

* **Improves compatibility across deployments**: Helps detect and resolve version, driver, and environment compatibility issues early, reducing friction across diverse infrastructure setups.

* **Accelerates troubleshooting and bug resolution**: Allows NVIDIA to diagnose errors and regressions faster, leading to quicker support response times and higher overall availability.

* **Informs smarter optimizations and future releases**: Real-world, aggregated telemetry data helps guide the optimization of NIM runtimes, model packaging, and deployment workflows, ensuring updates target the scenarios that matter most to users.

* **Protects user privacy and data security**: Collects only minimal, anonymous metadata, such as hardware type and NIM version. No user data, input sequences, or prediction results are collected.

* **Fully optional and configurable**: Telemetry collection is disabled by default. You can toggle telemetry at any time using environment variables.

**Configuration:**

* Set `NIM_TELEMETRY_MODE=0` to disable telemetry (default)
* Set `NIM_TELEMETRY_MODE=1` to enable telemetry

For more information about data privacy, what is collected, and how to configure telemetry, refer to:

* [NVIDIA's Privacy Policy](https://www.nvidia.com/en-us/about-nvidia/privacy-policy/)
* [NIM Telemetry Settings](https://developer.nvidia.com/docs/nim-tools/latest/templates/nimlib/nim-telemetry.html)

### Supported Features

All features from release 1.0.0 remain supported, with the addition of structural templates for protein molecules.

## October 27, 2025
