Cohere vs Relace: key differences
Relace and Cohere both offer self-hosting, for very different models. Relace's relace-apply-3 merges lazy edit snippets into files at about 10,000 tokens per second with 128K of input and output, and Relace says it runs over 3x faster and cheaper than having a frontier model rewrite the file. Its agentic search explores large codebases in parallel, and a compaction model runs at 50,000 tokens per second. Cohere's Command A handles general reasoning and tool use with 256K context at $2.50 in and $10 out, and Embed 4 and Rerank 4 handle document retrieval rather than code retrieval.
Relace is a point solution for coding workflows with no general-purpose model serving, and requests over 128K tokens return an error, so very large files need a fallback. Cohere covers RAG, translation, multilingual chat through Aya and speech through Transcribe, and it sells through Bedrock, Azure and OCI as well as private VPC and on-prem installs. On code generation itself, Command A+ trails the latest open leaders, which is why a coding product would more likely combine Relace with a different generator. For app builders applying AI edits to user codebases, Relace is the relevant tool. For knowledge work over enterprise documents, Cohere is.
What Cohere and Relace do
Cohere
Cohere is a Toronto-based lab that sells models and platforms to banks, governments and large enterprises rather than consumers. Its generative line is the Command family. Command A+, released May 20, 2026, is a 218B-parameter mixture-of-experts model with 25B active, published under Apache 2.0 with a 128K context window, and it combines reasoning, vision, translation and tool use in one set of weights. Command A has a 256K window and lists at $2.50 in and $10 out per million tokens, while Command R7B costs $0.0375 in. June 2026 added North Mini Code, a 30B Apache 2.0 coding model, and the lineup also includes Aya multilingual models and Transcribe for speech.
Example models: Command A+, Command A, Embed 4, Rerank 4
Full Cohere profileRelace
Relace trains small, fast models that act as tools for coding agents. Its best-known product is Instant Apply: a frontier model writes a lazy edit snippet, and relace-apply-3 merges it into the original file at about 10,000 tokens per second with 128K tokens of input and output. Relace says this runs over 3x faster and cheaper than having the big model rewrite the file. It exposes both a REST endpoint and an OpenAI-compatible one, and the model is also listed on OpenRouter.
Example models: relace-apply-3, Relace agentic search
