Training Details

Training Data

Falcon-Mamba has been trained with ~ 5,500 GT mainly coming from Refined-Web, a large volume web-only dataset filtered and deduplicated. Similar to the others Falcon suite models, Falcon-Mamba has been trained leveraging a multi-stage training strategy to increase the context-length from 2,048 to 8,192. Moreover, inspired by the concept of Curriculum Learning, we carefully selected data mixtures throughout the training stages, considering both data diversity and complexity. Note that at inference the context-length is not relevant as the Mamba architecture has no limit on long range dependency. At the last training stage, small portion of high-quality curated data was used to further enhance performance.

Overall, the data sources included RefinedWeb-English, high quality technical data, code data and math data extracted from public sources. In particular, we used samples coming from Fineweb-edu during our last training stage.

The data was tokenized with the Falcon-7B/11B tokenizer.

Training Procedure

Falcon-Mamba-7B was trained on 256 H100 80GB GPUs for the majority of the training, using a 3D parallelism strategy (TP=1, PP=1, DP=256) combined with ZeRO.

Training Hyperparameters

Hyperparameter	Value	Comment
Precision	`bfloat16`
Optimizer	AdamW
Max learning rate	6.4e-4	Following a WSD (warmup-stable-decay) learning rate schedule
Weight decay	1e-1
Batch size	2048

The model was trained AdamW optimizer, WSD (warmup-stable-decay) learning rate schedule, and a batch size rampup from $b_{\mathrm{min}}=128$ to $b_{\mathrm{max}}=2048$ during first 50 GT of training. In the stable phase we used maximal learning rate $\eta_{\mathrm{max}}=6.4 \times 10^{-4}$ , and decayed it to the minimal value $\eta_{\mathrm{min}}=\frac{\eta_{\mathrm{max}}}{256}$ with exponential schedule over 500 GT. Also, we applied BatchScaling during the rampup — rescaling learning rate $\eta$ so that the Adam noise temperature $T_{\mathrm{noise}}\equiv\frac{\eta}{\sqrt{b}}$ is kept constant.

Speeds, Sizes, Times

The model training took roughly two months.

Evaluation

Benchmarks

We evaluate our model on all benchmarks of the new leaderboard's version using the lm-evaluation-harness package, and then normalize the evaluation results with HuggingFace score normalization.

Mostly, we took evaluation results from both leaderboards. For the models marked by star we evaluated the tasks internally, while for the models marked by two stars the results were taken from paper or model card.
