Updates sentence-transformers from 5.2.3 to 5.3.0

Release notes

Sourced from sentence-transformers's releases.

v5.3.0 - Improved Contrastive Learning, New Losses, and Transformers v5 Compatibility

This minor version brings several improvements to contrastive learning: MultipleNegativesRankingLoss now supports alternative InfoNCE formulations (symmetric, GTE-style) and optional hardness weighting for harder negatives. Two new losses are introduced, GlobalOrthogonalRegularizationLoss for embedding space regularization and CachedSpladeLoss for memory-efficient SPLADE training. The release also adds a faster hashed batch sampler, fixes GroupByLabelBatchSampler for triplet losses, and ensures full compatibility with the latest Transformers v5 versions.

Install this version with

# Training + Inference
pip install sentence-transformers[train]==5.3.0
Inference only, use one of:
pip install sentence-transformers==5.3.0
pip install sentence-transformers[onnx-gpu]==5.3.0
pip install sentence-transformers[onnx]==5.3.0
pip install sentence-transformers[openvino]==5.3.0

Updated MultipleNegativesRankingLoss (a.k.a. InfoNCE)

MultipleNegativesRankingLoss received two major upgrades: support for alternative InfoNCE formulations from the literature, and optional hardness weighting to up-weight harder negatives.

Support other InfoNCE variants (#3607)

MultipleNegativesRankingLoss now supports several well-known contrastive loss variants from the literature through new directions and partition_mode parameters. Previously, this loss only supported the standard forward direction (query → doc). You can now configure which similarity interactions are included in the loss:

• "query_to_doc" (default): For each query, its matched document should score higher than all other documents.
• "doc_to_query": The symmetric reverse — for each document, its matched query should score higher than all other queries.
• "query_to_query": For each query, all other queries should score lower than its matched document.
• "doc_to_doc": For each document, all other documents should score lower than its matched query.

The partition_mode controls how scores are normalized: "joint" computes a single softmax over all directions, while "per_direction" computes a separate softmax per direction and averages the losses.

These combine to reproduce several loss formulations from the literature:

Standard InfoNCE (default, unchanged behavior):

loss = MultipleNegativesRankingLoss(model)
# equivalent to directions=("query_to_doc",), partition_mode="joint"

Symmetric InfoNCE (Günther et al. 2024) — adds the reverse direction so both queries and documents are trained to find their match:

loss = MultipleNegativesRankingLoss(
    model,
    directions=("query_to_doc", "doc_to_query"),
    partition_mode="per_direction",
)

GTE improved contrastive loss (Li et al. 2023) — adds same-type negatives (query <-> query, doc <-> doc) for a stronger training signal, especially useful with pairs-only data:

loss = MultipleNegativesRankingLoss(
