Bamba-9B-v1

ibm-ai-platform · Bamba-9B-v1

We introduce Bamba-9B, a decoder-only language model based on the Mamba-2 architecture and is designed to handle a wide range of text generation tasks. It is trained from scratch using a two-stage training approach. In the first stage, the model is trained on 2 trillion tokens from the Dolma v1.7 dataset. In the second stage, it undergoes additional training on 200 billion tokens, leveraging a carefully curated blend of high-quality data to further refine its performance and enhance output quality. The current release includes the following models: | **Stage** | **Bamba 9B** | **Quantized** | **Note** | |----------------------|----------------------------------------------------------------------|-------------------------------------------------------------------------|-------------------------------------------------------------------| | **Base Model** | ibm-fms/Bamba-9B-v1 | ibm-fms/Bamba-9B-fp8 | Stage 2 pretraining | | **Base Model** | ibm-fms/Bamba-9B-2T | ibm-fms/Bamba-9B-fp8 | Stage 1 pretraining | | **Base Model** | ibm-fms/Bamba-9B-1.8T| ibm-fms/Bamba-9B-fp8 | Intermediate checkpoints during Stage 1, more to come | | **SFT** | coming soon | coming soon | to be released in the next drop | | **DPO** | coming soon | coming soon | to be released in the next drop | For users using our HF versions of the model, you would need to install the latest transformers which includes our newly merged implementation for our Bamba models:

Frequently asked questions

Do open weights permit free commercial use?

Not necessarily. Check the version license, commercial conditions and usage policies. Self-hosting incurs compute and maintenance costs.

Are these real-time billing prices?

These are timestamped source snapshots, not live billing prices. Check the channel for current versions, regions, discounts and billing methods.
