Embed 5 Fast

Embed 5 Fast is the lower-latency, cost-efficient tier of Cohere's Embed 5 family of multimodal embedding models (about 1B parameters). It embeds text, images, and interleaved text and image content in over 100 languages with a 128K-token context, and shares one embedding space with Embed 5 Pro, so it suits querying an index built with Pro.

Input / output price: $0.12 / $0.00 per 1M
Context: 128K tokens
Released: Sep 30, 2026
