Introduction of NexusLM-BenchHub
Model Details of NexusLM-BenchHub
NexusLM
1. Introduction
NexusLM is the latest generation language model trained with a curriculum-based data mixture and a revised post-training recipe. During development we tracked fifteen benchmark suites after every 100 training steps, and the release candidate was selected as the checkpoint with the strongest overall evaluation accuracy rather than simply the last one. The selected model balances deep reasoning ability with robustness on open-ended generation tasks.
One notable finding from our training runs: pushing past the selected checkpoint did not help. In later checkpoints, several reasoning benchmarks actually regress while a handful of easy classification tasks keep inching up, which is why checkpoint selection based on the full benchmark suite matters for this release.

Overall Performance Summary
NexusLM shows well-rounded performance across all evaluated benchmark categories, with the strongest gains concentrated in reasoning-heavy and code-related tasks.
3. Chat Website & API Platform
We host an interactive demo and an API endpoint for NexusLM. See our project homepage for access details and rate limits.
4. How to Run Locally
The code for loading and serving NexusLM lives in our main GitHub repository. Check there for installation steps and quantization recipes.
Compared to the previous generation, the usage recommendations for NexusLM changed as follows:
- A system prompt is now supported and encouraged.
- No special tokens are needed at the start of the output to trigger a particular reasoning mode.
The architecture of NexusLM-Small matches the base model and shares its tokenizer configuration, so it runs with the same code paths.
System Prompt
We recommend the following system prompt with a concrete date.
You are NexusLM, a helpful AI assistant.
Today is {current date}.
For example,
You are NexusLM, a helpful AI assistant.
Today is October 5, 2026, Monday.
Temperature
We recommend setting the temperature parameter $T_{model}$ to 0.7.
Prompts for File Uploading and Web Search
For file uploading, build prompts from the following template, where {file_name}, {file_content} and {question} are arguments.
file_template = \
"""[file name]: {file_name}
[file content begin]
{file_content}
[file content end]
{question}"""
For web-search-augmented generation, the recommended template places the search results ahead of the user question and instructs the model to cite the sources it actually used, as in the example shipped in our repository.
