With demand for enterprise retrieval augmented era (RAG) on the rise, the chance is ripe for mannequin suppliers to supply their tackle embedding fashions.
French AI firm Mistral threw its hat into the ring with Codestral Embed, its first embedding mannequin, which it stated outperforms current embedding fashions on benchmarks like SWE-Bench.
The mannequin focuses on code and “performs particularly properly for retrieval use circumstances on real-world code information.” The mannequin is offered to builders for $0.15 per million tokens.
The corporate stated the Codestral Embed “considerably outperforms main code embedders” like Voyage Code 3, Cohere Embed v4.0 and OpenAI’s embedding mannequin, Textual content Embedding 3 Massive.
Codestral Embed, a part of Mistral’s Codestral household of coding fashions, could make embeddings that rework code and information into numerical representations for RAG.
“Codestral Embed can output embeddings with totally different dimensions and precisions, and the determine beneath illustrates the trade-offs between retrieval high quality and storage prices,” Mistral stated in a weblog publish. “Codestral Embed with dimension 256 and int8 precision nonetheless performs higher than any mannequin from our rivals. The size of our embeddings are ordered by relevance. For any integer goal dimension n, you possibly can select to maintain the primary n dimensions for a easy trade-off between high quality and value.”
Mistral examined the mannequin on a number of benchmarks, together with SWE-Bench and Text2Code from GitHub. In each circumstances, the corporate stated Codestral Embed outperformed main embedding fashions.

Use circumstances
Mistral stated Codestral Embed is optimized for “high-performance code retrieval” and semantic understanding. The corporate stated the code works greatest for no less than 4 sorts of use circumstances: RAG, semantic code search, similarity search and code analytics.
Embedding fashions usually goal RAG use circumstances, as they’ll facilitate sooner info retrieval for duties or agentic processes. Due to this fact, it’s not stunning that Codestral Embed would give attention to that.
The mannequin can even carry out semantic code search, permitting builders to search out code snippets utilizing pure language. This use case works properly for developer device platforms, documentation methods and coding copilots. Codestral Embed can even assist builders establish duplicated code segments or related code strings, which could be useful for enterprises with insurance policies concerning reused code.
The mannequin helps semantic clustering, which includes grouping code based mostly on its performance or construction. This use case would assist analyze repositories, categorize and discover patterns in code structure.
Competitors is rising within the embedding area
Mistral has been on a roll with releasing new fashions and agentic instruments. It launched Mistral Medium 3, a medium model of its flagship massive language mannequin (LLM), which at present powers its enterprise-focused platform Le Chat Enterprise.
It additionally introduced the Brokers API, which permits builders to entry instruments for creating brokers that carry out real-world duties and orchestrate a number of brokers.
Mistral’s strikes to supply extra mannequin choices to builders haven’t gone unnoticed in developer areas. Some on X word that Mistral’s timing in releasing Codestral Embed is “approaching the heels of elevated competitors.”
Nonetheless, Mistral should show that Codestral Embed performs properly not simply in benchmark testing. Whereas it competes towards extra closed fashions, equivalent to these from OpenAI and Cohere, Codestral Embed additionally faces open-source choices from Qodo, together with Qodo-Embed-1-1.5 B.
