Interactive Demo:
Our models would be temporarily offline due to GPU limitation (if we need to train new models lol). You can refer to ποΈ Run Otter Locally to try Otter-Image and Otter-Video more smoothly on your local machine, with at least 16G GPU mem (BF16/FP16 Mode) to help your tasks like image/video tagging, captioning or identifying harmful content.
Checkpoints:
- Checkpoints v0.1 (image version)
- Checkpoints v0.2 (video version, trained on MIMIC-IT-DC)
- Checkpoints v0.2 (video version, trained on MIMIC-IT all videos, upcoming)
- Checkpoints v0.3 (Otter-E, visual assistant version, upcoming)
Otter v0.1 supports multiple images inputs as in-context examples, which is the first multi-modal instruction tuned model that supports to organize inputs this way.
Otter v0.2 supports videos inputs (frames are arranged as original Flamingo's implementation) and multiple images inputs (they serve as in-context examples for each other).

- ποΈ Run Otter Locally. You can run our model locally with at least 16G GPU mem for tasks like image/video tagging and captioning and identifying harmful content. We fix a bug related to video inference where
frame tensors
were mistakenly unsqueezed to a wrongvision_x
. You can now try running it again with the updated version.Make sure to adjust the
sys.path.append("../..")
correctly to accessotter.modeling_otter
in order to launch the model.

- Check our paper introducing MIMIC-IT in details. Meet MIMIC-IT, the first multimodal in-context instruction tuning dataset with 2.8M instructions! From general scene understanding to spotting subtle differences and enhancing egocentric view comprehension for AR headsets, our MIMIC-IT dataset has it all.
- Stay tuned for our upcoming Otter Model v0.2, trained on the MIMIC-IT dataset! With the ability to understand daily scenes, reason in context, spot differences in observations, and act as an egocentric assistant. Checkout conceptual demo video at Youtube or Bilibili!
Large Language Models (LLMs) have demonstrated exceptional universal aptitude as few/zero-shot learners for numerous tasks, owing to their pre-training on extensive text data. Among these LLMs, GPT-3 stands out as a prominent model with significant capabilities. Additionally, variants of GPT-3, namely InstrctGPT and ChatGPT, have proven effective in interpreting natural language instructions to perform complex real-world tasks, thanks to instruction tuning.
Motivated by the upstream interleaved format pretraining of the Flamingo model, we present 𦦠Otter, a multi-modal model based on OpenFlamingo (the open-sourced version of DeepMind's Flamingo). We train our Otter in an in-context instruction tuning way on our proposed MI-Modal In-Context Instruction Tuning (MIMIC-IT) dataset. Otter showcases improved instruction-following and in-context learning ability in both images and videos.
MIMIC-IT enables the application of egocentric visual assistant model that can serve that can answer your questions like Hey, Do you think I left my keys on the table?. Harness the power of MIMIC-IT to unlock the full potential of your AI-driven visual assistant and elevate your interactive vision-language tasks to new heights.
We also introduce Syphus, an automated pipeline for generating high-quality instruction-response pairs in multiple languages. Building upon the framework proposed by LLaVA, we utilize ChatGPT to generate instruction-response pairs based on visual content. To ensure the quality of the generated instruction-response pairs, our pipeline incorporates system messages, visual annotations, and in-context examples as prompts for ChatGPT.
For more details, please check the MIMIC-IT dataset.
Otter is designed to support multi-modal in-context instruction tuning based on the OpenFlamingo model, which involves conditioning the language model on the corresponding media, such as an image that corresponds to a caption or an instruction-response pair.
We train Otter on MIMIC-IT dataset with approximately 2.8 million in-context instruction-response pairs, which are structured into a cohesive template to facilitate various tasks. Otter supports videos inputs (frames are arranged as original Flamingo's implementation) and multiple images inputs as in-context examples, which is the first multi-modal instruction tuned model.
The following template encompasses images, user instructions, and model-generated responses, utilizing the User
and GPT
role labels to enable seamless user-assistant interactions.
prompt = f"<image>User: {instruction} GPT:<answer> {response}<endofchunk>"
Training the Otter model on the MIMIC-IT dataset allows it to acquire different capacities, as demonstrated by the LA and SD tasks. Trained on the LA task, the model exhibits exceptional scene comprehension, reasoning abilities, and multi-round conversation capabilities.
# multi-round of conversation
prompt = f"<image>User: {first_instruction} GPT:<answer> {first_response}<endofchunk>User: {second_instruction} GPT:<answer>"
Regarding the concept of organizing visual-language in-context examples, we demonstrate here the acquired ability of the Otter model to follow inter-contextual instructions after training on the LA-T2T task. The organized input data format is as follows:
# Multiple in-context example with similar instructions
prompt = f"<image>User:{ict_first_instruction} GPT: <answer>{ict_first_response}<|endofchunk|><image>User:{ict_second_instruction} GPT: <answer>{ict_second_response}<|endofchunk|><image>User:{query_instruction} GPT: <answer>"
For more details, please refer to our paper's appendix for other tasks.
- Compare cuda version returned by nvidia-smi and nvcc --version. They need to match. Or at least, the version get by nvcc --version should be <= the version get by nvidia-smi.
- Install the pytorch that matches your cuda version. (e.g. cuda 11.7 torch 2.0.0). We have successfully run this code on cuda 11.1 torch 1.10.1 and cuda 11.7 torch 2.0.0. You can refer to PyTorch's documentation, Latest or Previous.
- You may install via
conda env create -f environment.yml
. Especially to make sure thetransformers>=4.28.0
,accelerate>=0.18.0
.
After configuring environment, you can use the 𦩠Flamingo model / 𦦠Otter model as a π€ Hugging Face model with only a few lines! One-click and then model configs/weights are downloaded automatically. Please refer to Huggingface Otter/Flamingo for details.
Train on MIMIC-IT
datasets, using the following commands:
First, run, and answer the questions asked. This will generate a config file and save it to the cache folder. The config will be used automatically to properly set the default options when doing accelerate launch
.
accelerate config
Then run the training script. You may need to use a specialized converted weights at luodian/OTTER-9B-INIT. This is for initilizing training for Otter. It's directly converted from Openflamingo, and we added tokens for downstream instruction tuning. And you may use any trained weights to start with your training on top of ours, see weights at Otter Weights, and MIMIC-IT for preparing json files.
