🎯 AuroraGPT: Goals

AuroraGPT: General purpose scientific LLM
Broadly trained on a general corpora plus scientific {papers, texts, data}

  • Explore pathways towards a “Scientific Assistant” model
  • Build with international partners (RIKEN, BSC, others)
  • Multilingual English, 日本語, French, German, Spanish
  • Multimodal: images, tables, equations, proofs, time series, graphs, fields, sequences, etc

  • Here to talk about AuroraGPT, Argonne’s internal effort to build a general purpose scientific LLM, broadly trained on a general corpora of text + scientific {papers, text, data}
  • As part of this effort, we plan to…
    • Explore pathways, build with international partners, multi-{lingual, modal}
  • Rough timeline of the project and deliverables:
    • 202{3,4}: text-only models, plan to release a series of {7B, 70B, 1T} models
    • 202{4,5}: Basic multi-modal models
    • 202{5,6}: Advanced scientific multimodal models

🦙 Issues with “Publicly Available” LLMs

  • Trust and Safety:
    • Skepticisim about deployment in critical infrastructure
    • Correctness and reliability of model outputs
  • Transparency:
    • Data governance, what was used for pre-training? fine-tuning?
      • generally unknown
    • What is open source?
      • Model weights?
      • Pre-training {code, logs, metrics} ?
  • Why are we doing this?
  • What is the issue with current LLMs?
    • Trust and safety
      • Hallucinations, false confidence
      • Can this be reliably mitigated?
      • Scaling up inference compute seems to help
        • reasoning models, TTT, etc.
    • Transparency
      • Different frontier labs have different definitions of “open source”
      • e.g. Llama no longer releases base models
        • Libgen ??
      • AllenAI institute, olmo models good example

🧪 AuroraGPT: Open Science Foundation Model

Figure 3: High-level overview of AuroraGPT project
  • AuroraGPT will be a publicly distributed, open source foundation model for open science
  • Is being trained on:
    • Scientific / engineering structured data
    • General text, media, news, etc.
    • Large amounts of low to medium quality data
    • Much less high quality data (that is publicly available for use)
  • This data is then cleaned, processed, de-duplicated and used for the initial pre-training phase of the model
  • The vast majority of the overall compute is spent during this initial pre-training phase
    • This is the group I help to lead and will be talking a bit about today
  • The initial pre-training phase is currently underway
    • Eventually, given a bit of time, effort and magic, the model will be ready for fine-tuning and additional training for a variety of downstream tasks
  • The pretrained model will then be handed off for additional fine-tuning on a variety of downstream tasks
    • Scientific discovery
    • Accelerate scientific tasks
    • Digital twins
    • Inverse design
    • Code optimization
    • Accelerated simulations
    • Autonomous experiments
    • Co-design
  • Becoming increasingly clear that LLMs have the potential to drastically accelerate computational science
    • We’ve seen this already for {GenSLMs, Weather / Climate / Earth Systems Modeling, Particle Physics, etc.}

📊 AuroraGPT: Outcomes

  • Datasets and data pipelines for preparing science training data

  • Software infrastructure and workflows to train, evaluate and deploy LLMs at scale for scientific resarch purposes

    • argonne-lcf/Megatron-DeepSpeed
      End-to-end training and inference, on any GPU cluster
    • argonne-lcf/inference-endpoints1
      Inference endpoints for LLMs, hosted @ ALCF
  • Evaluation of state-of-the-art LLM Models:
    • Determine where they fall short in deep scientific tasks
    • Where deep data may have an impact

  1. Relies heavily on Globus (next talk!)

📚 What do we hope to get?

  • Assessment of the approach of augmenting web training data with two forms of data specific to science:
    • Full text scientific papers
    • Structured scientific datasets (suitably mapped to narrative form)
  • Research grade artifacts (models) for scientific community for adaptation for downstream uses1
  • Promotion of responsible AI best practices where we can figure them out
  • International Collaborations around the long term goal of AGI for science
  • Deliverables:
    • datasets, pipelines
    • software infrastructure, workflows to interface with science applications
    • checkpoints, models, logs, workbook, insights, etc.
  • Hope to understand:
    • How different state-of-the-art models perform at different scientific tasks
    • where deep data may have an impact
    • feasibility of generically augmenting text with scientific structured data
  • Huge undertaking that will require large international collaborations around long term goal of AGI for science
  • Extra points:
    • Well known that LLMs are good for non-consequential tasks
    • Known to “hallucinate” and create false information
    • Can this be mitigated reliably ??

📚 Data

✅ Goal: Assemble a large corpus of documents (general and scientific) to train and fine-tune AuroraGPT models

  • Challenges: Avoid / detect contamination with benchmarks
    • Respect copyright (ACM Digital Library), privacy, and ethical considerations
  • Performance Challenges: High throughput data processing
    • Converting PDF → text (math formula, figures)
    • Convert science information (data) into text (narratives)
    • De-duplication (syntactic and semantic) of scientific documents (to avoid memorization, bias)
  • Quantity: Considering 20+ Trillion tokens → ≈ 100M papers
  • Domains: All (long-term) scientific domains, starting with:
    • Material science, Physics, Biology, Computer Science, Climate Science

⏱️ Dataset Processing

  • To train a fixed model on trillions of tokens requires:
    1. Aggregating data from multiple different corpora
      (e.g. ArXiv, Reddit, StackExchange, GitHub, Wikipedia, etc.)
    2. Sampling each training batch according to a fixed distribution across corpora
    3. Building indices that map batches of tokens into these files (indexing)

    The original implementation was slow:

    • Designed to run serially on a single device
    • Major bottleneck when debugging data pipeline at scale

🚀 Accelerating Dataset Processing: Results

  • Original implementation:
    • Slow!
    • 🐌 ~ 1 hr/2T tokens
    • Wrote asynchronous, distributed implementation
    • significantly improves performance (30x !!)
    • 🏎️💨 ~ 2 min/2T tokens
Figure 9: Time spent preparing 2T tokens

🦜 Model Training

✅ Goals

  • Want training runs at scale to be:
    • efficient
    • stable
    • reproducible
  • This requires:
    • robust data pipelines / file IO
    • effectively overlapping compute with communication
    • stability across {network, filesystem, machine}
  • 3D / Multi-dimensional Parallelism strategies
  • Large batch training
  • Second order optimizers
  • Sub-quadratic attention
  • State space models
  • Highly optimized GPU kernels

❌ Challenges

  • Looong time to train, can be:
    • weeks (even months) of continuous training
    • order of magnitude longer than typical NN training jobs
  • Stability issues:
    • failures are expensive (but inevitable)
    • stragglers common at scale
  • Individual jobs are:
    • fragile
    • only as good as the worst rank
    • one hang or bad worker can crash job
    • network / filesystem / other-user(s) dependent
  • Cost / benefits of different collective communication algorithms
    • depend on optimized / efficient implementations
  • Network performance
  • Highly optimized GPU kernels

argonne-lcf / Megatron-DeepSpeed

🤔 Evaluating FM Skills for Science

  • What to measure?
    • Knowledge Extraction, Retrieval, Distillation, Synthesis: LLM is provided a question or instruction and a truthful answer is expected
    • Text Grounded: Answers are expected to be fully grounded on peer-reviewed references to support responses
    • Reasoning: LLMs are expected to solve deductive (prove a theory or hypothesis from formal logic and observations), inductive (validate / explain observations from theories) problems
    • Creativity: A creative answer is expected from a question or instruction
      • thoughtful dialogue, coding, etc.

⚖️ Evaluating FM Skills for Science: Criteria

  • Criteria for all of the above:
    • Correctness of facts
    • Accuracy of solutions and inferences
    • Reliability consistently good in quality or performance
    • Speed how fast to produce a response
    • # shots how many examples are needed for good quality
      • Extent of prompt engineering
