TimePLE-8B is a Qwen3-VL-8B-Instruct model fine-tuned for video temporal grounding. Given a video and a natural-language event description, it represents and predicts the event's start/end span through a duration-adaptive TimePLE codec.
This is an inference release: it contains the selected stage-2 model weights and tokenizer/processor assets. The TimePLE model implementation is maintained in the public TimePLE source repository instead of being duplicated in this model repository. Optimizer, scheduler, RNG, and distributed-training states are intentionally excluded.
Requirements and loading
Install the TimePLE package from its public GitHub repository first, then install the pinned runtime dependencies from this directory:
Importing timeple registers the TimePLE configuration, model, and processor with Transformers. The model repository contains no executable Python code and does not require trust_remote_code=True.

The TimePLE source repository provides the video preparation, temporal decoding, and benchmark runners. For example:
The plain Transformers load above verifies and exposes the model; use the repository's TimePLE inference/evaluation path for decoded temporal intervals because it supplies video durations and the task-specific post-processing contract.
Language model, TimePLE codec, and MLP interface adapter: trainable during stage-2 SFT

The tokenizer vocabulary has 151,671 entries. It preserves all 13 Qwen3-VL additional special tokens and appends:

The TimePLE codec uses a 128×128 canonical span grid, a duration-adaptive residual decoder, and a learned MLP interface adapter to the 4096-dimensional language-model representation.
Intended use
This model is intended for research and evaluation of temporal localization in videos from a textual event query. Suitable uses include moment retrieval experiments, temporal-grounding ablations, and further task-specific fine-tuning.
Limitations
Temporal quality depends on frame sampling, video duration metadata, and the inference pipeline's video preprocessing.
The training data and prompts are primarily English; other languages and unseen domains have not been established here.
Long, ambiguous, repeated, or extremely brief events may yield unstable boundaries.
The reported validation result comes from the training-time validation mixture and should not be compared directly with benchmark test results produced under different sampling or evaluation protocols.
The model inherits limitations and potential biases of Qwen3-VL and of the stage-1/stage-2 training data.
Release contents and integrity
Model parameters—including all TimePLE codec and adapter parameters—are stored in the indexed safetensors shards. No pickle-based .bin, .pt, or .pth weight file is required. The model directory contains no executable Python implementation; AutoClass registration is provided by the separately installed timeple package.
