Cohere doesn't make front-page headlines the way OpenAI and Anthropic do. That's unfortunate, because Embed v4 is the most accurate retrieval model we've tested for marketing content — and retrieval quality is what makes or breaks an AI marketing stack.
Why retrieval matters more than the model
A top-tier LLM with bad retrieval produces confident hallucinations. A mediocre LLM with great retrieval produces reliable, cited answers. In practice, the second setup wins every client engagement we run.
Embed v4 is better at matching 'what the user actually meant' to 'what a document actually contains' than the alternatives we've benchmarked. The gap is small on clean data and huge on messy, real-world marketing corpora.
Multilingual is a cheat code
Embed v4's multilingual quality is close to English-only performance. For brands with content in 10+ languages, that collapses a whole class of architecture decisions: you don't need per-language indexes, per-language models, or per-language QA.
Our Spanish-language clients saw citation accuracy jump 18% after switching to Embed v4. That's not a rounding error.
When to switch
- You have a RAG pipeline and your citation accuracy is under 90%.
- You're working across 3+ languages.
- Your content corpus is over 1 million chunks.
- You're seeing the retrieval step — not the LLM — as your bottleneck.
Great retrieval is the unsexy half of every great AI product. Embed v4 is where serious teams quietly end up.
