SAVRN's Take

Every retrieval pipeline we stand up starts with one of these. A feature extraction model turns a passage of text, or in one case audio, into a fixed-length vector a database can compare against millions of others, which is how semantic search finds the right chunk. The Beijing Academy of Artificial Intelligence leads the 77 entries with 8 models, and its bge-small-en-v1.5 pulls 64,516,396 downloads a month, more than five times the 11,607,634 of bge-large-en-v1.5. Qwen and Jina AI follow with 3 each.

Hardware is the easy part. bge-small-en-v1.5 needs 0.1 GB at 16-bit, and even Qwen3-Embedding-8B at 7.6B parameters fits in 18.2 GB, or 4.5 GB at 4-bit. The cheapest Index host for all of them is a single MI300X at $1.85 an hour, so the question in our facilities is how much of a card to give the embedding service beside the generation model it feeds. Context length is where the choices separate: the BGE English models stop at 512 tokens, which means chunking every document, while granite-embedding-small-english-r2 takes 8,192 in 48M parameters and the Qwen3 embedding models take 32,768 at 0.6B and 40,960 at 8B.

Licensing rarely blocks a deployment. 54 of the 77 are MIT and 15 are Apache-2.0, both fine for commercial use. Seven state no license and one is cc-by-nc-4.0, so check those eight first. Then weigh vector width: the Granite model emits 384 dimensions, multilingual-e5-large 1024, and the wider vector costs more to store per chunk. Weigh language too: bge v1.5 comes in English and Chinese editions, and multilingual-e5-large covers 100 languages.

It requires finetuning to be used for downstream tasks such as Automatic Speech Recognition (ASR), or Audio Classification. This model and its training are supported by Transformers, more on it in the docs. This is a bare checkpoint without any modeling head, and thus requires finetuning to be used for downstream tasks such as ASR.

This is the model card of a transformers model that has been pushed on the Hub. Users (both direct and downstream) should be made aware of the risks, biases and limitations of the model. Use the code below to get started with the model. Carbon emissions can be estimated using the Machine Learning Impact calculator presented in Lacoste et al. (2019).

meta-encoder

AI at Meta

Multimodal System One Encoder with a natural language interface for instruction-following encoding: give it a task and a list of candidates, and it scores the candidates by task specification. Both a task and each candidate are expressed in natural language — instructions, queries, questions, state descriptions, criteria — with image and video as side information. - Natural language interface. No rigid schemas. Describe the task and the candidates in free-form text. - Highly-efficient cacheable representations. Candidates and task are encoded separately by prompt instructions that ground each other. - Scales to arbitrarily large candidate sets. Matching is an inner product over…

jina-embeddings-v5-omni-small

Jina AI

Average score vs. parameter count across image (MIEB-Lite), video (MMEB-V), and audio (MAEB) benchmarks — jina-v5-omni-nano and jina-v5-omni-small define the open-weight frontier (Table 1 in the ArXiv report). jina-embeddings-v5-omni-small is a multimodal embedding model that accepts text, images, video, and audio and produces embeddings in a shared vector space aligned with the text-only jinaai/jina-embeddings-v5-text-small — so you can index with text and query with any modality, no reindexing. For a more compact alternative, see jinaai/jina-embeddings-v5-omni-nano. This is the base repository — it holds all task adapters (retrieval, classification, clustering, text-matching). For a…

SheetSage2-GGUF

Audio.cpp

GGUF conversion of m-a-p/SheetSage2 for audio.cpp. SheetSage2 transcribes music into melody, chords, beats, key, structure, and editable scores. This is a converted checkpoint, not a new model or an official upstream release. The packaged file uses the audio.cpp SheetSage2 runtime, not the upstream Transformers loader. The upstream model.safetensors is only 228,738,564 bytes (228.74 MB): it contains SheetSage2 adapters and task-specific weights and relies on the separately downloaded MERT-v2-FullSong backbone. The GGUF includes that backbone with the LoRA updates already merged, plus the task weights and embedded configuration. No separate backbone checkpoint is needed at inference time.…

Qwen3-Voice-Embedding-12Hz-1.7B

Markus

Standalone ECAPA-TDNN voice encoder extracted from Qwen/Qwen3-TTS-12Hz-1.7B-Base. Produces 2048-dimensional x-vector speaker embeddings from audio. The encoder follows the ECAPA-TDNN architecture (Emphasized Channel Attention, Propagation and Aggregation in TDNN Based Speaker Verification) and uses Res2Net blocks, squeeze-excitation attention, and attentive statistical pooling. Speaker embeddings can be stored and shared as SafeTensors files. These embeddings are designed to drive voice cloning in the Qwen3-TTS family. There are two main inference paths: the qwentts Python package and the vLLM-Omni serving API. The qwentts package wraps the TTS model and exposes generatevoiceclone. To…

starwell

Charles Norton

Starwell is a generative model for stellarator design. Given a number of field periods, an aspect ratio and a target magnetic-gradient scale length LgradB, it samples a plasma boundary for the mhdstable problem of the ConStellaration benchmark, predicts its benchmark metrics, and lays out modular coils for it. Boundaries are SurfaceRZFourier dicts (rcos, zsin) that constellaration evaluates directly; sample also takes tau, guidance, steps and seed, and model.config.sampling holds the integrator's defaults. Coils are simsopt CurveXYZFourier coefficients for one half period with their currents, and simsopt.field.coilsviasymmetries builds the full set; limits (in metres and per metre) sets the…

CLIP_ViT-B32

Eidora.org

CLIP helps researchers find images using written descriptions. It can also compare pictures with one another, or compare text and images in the same collection. A researcher working with historical photographs or newsreel frames could search for descriptions such as “a crowd in a public square” and inspect the closest matches. Choose CLIP when searching images with words matters; an image-only model such as DINO is another option for exploring visual similarity without text. These are possible research uses, not claims that this EIDORA package has been evaluated on historical collections. CLIP was trained largely on internet images and English-language text. It may miss details in…

Corpus-ViT

Gugu8

A vision encoder with a runtime-selectable token budget, built to sit between an image and an LLM. A coarse 32px grid covers the whole image; a router spends extra 16px detail only on the regions that need it. Output length is 49 + 3k tokens — 49 at k=0, 121 at k=24 — so you choose the tokens/fidelity trade-off per image, at inference, with no retraining. 24.94M parameters. Trained in 6000 steps (~30 min) on 2× Kaggle T4 by distillation from google/siglip-base-patch16-224 (86M). This is a working, honest baseline, not a competitive encoder. On the Flickr30k official test split it reaches 8.95 mean R@1 against the teacher's 83.25 — roughly 10% of its teacher. Chance on 1000 images is 0.10.…

CLM-v0.1-8B-MLX

Zhu Lin

The encoder half of Contrastive-LM/CLM-v0.1-8B, quantised for MLX on Apple Silicon. One repository per bit width, matching mlx-community.

Agreement against a bf16 MLX reference of the same encoder in the same runtime, over 23,926 scored System One questions, through the real head stack (argmax(scale · cos), scale = 100.0 — cosine error is amplified 100×). Pass line. top-1 >= 1.0000 — the measured bf16-vs-bf16 noise floor of this corpus in this runtime — and top-1 (decisive) >= 0.995, where decisive means the reference's own top-1 led by more than 1 nat.

continuous-mimi-onnx

MaAI

This is a modified ONNX export of the Mimi audio codec encoder. It bypasses the Residual Vector Quantization (RVQ) to directly output continuous feature representations instead of discrete tokens. This preserves fine-grained acoustic details, making it ideal for downstream tasks like real-time dialogue analysis or speech emotion recognition. This model is a derivative work based on the "Mimi" model. Numbers below are illustrative (desktop CPU, FP32 ONNX vs PyTorch kyutai/mimi, streaming chunk emit=1280 @ 16 kHz, inference.py --compare). Your machine, thread counts, and ORT / PyTorch builds will shift them. Speed — RTF (processing time ÷ real-time audio length per chunk) In repeated 1-second…
