I just started to look into multi-modal embedding models recently, and I was surprised how few options there are.

For example, Google's model only supports 30 text tokens [1]!!

This is definitely a welcome addition.

Any pointers to similarly powerful embedding models? I'm looking specifically for text and images? I wish there'd be also one that could do audio and video, but I don't think that exists.

I have huge respect for Cohere and this embedding model looks like it could be best-in-class, but I find it hard to commit to a proprietary embedding model that's only available via an API when there are such good open weight models available.

I really like the approach Nomic take: their most recent models are available via their API or as open weights for non-commercial use only (unless you buy a license). They later relicense their older models under Apache 2.0 licenses.

This gives me confidence that I can continue to use my calculated vectors in the future even if Nomic's model is no longer available because I can run the local one instead.

Nomic Embed Vision 1.5 for example started out as CC-BY-NC-4.0 but was later relicensed to Apache 2.0: https://www.nomic.ai/blog/posts/nomic-embed-vision

Wondering how this compares to the Gemini (preview) embeddings as they seem to perform significantly better than OpenAI embeddings 3 large. I don't see any MTEB scores so hard to compare.

Seems to under-perform voyage-3-large on the same benchmark. At the same time, I'm unsure how useful benchmarks are for embeddings.

I had the same thought, although voyage is 32k vs 128k for cohere 4.

Anecdotal evidence points to benchmarks correlating with result quality for data I've dealt with. I haven't spent a lot of time comparing results between models, because we were happy with the results after trying a few and tuning some settings.

Unless my dataset lines up really well with a benchmark's dataset, creating my own benchmark is probably the only way to know which model is "best".

Curious for those in the industry, is there room for Cohere? Apparently they are doing very well in the enterprise, however recently I found myself wondering what their long term value prop is.
