Google Vertex AI vs Cohere: key differences

Vertex AI is a platform, Cohere is a model vendor. Vertex's Model Garden offers 200+ models including Gemini 3.8, Claude and Gemma, with Gemini 3.8 Flash at $0.75 in and $3.75 out and a 1M window. Around them sit Agent Studio, the Agent Development Kit, Memory Bank, custom training on GPUs or TPUs and deep BigQuery integration. Cohere offers the Command family, with Command A at $2.50 in and $10 out and 256K context, plus Embed 4 and Rerank 4 for retrieval and the North platform for internal agents. On context length, multimodal breadth and per-token price on Flash, Vertex has the edge.

Portability is Cohere's strongest argument. Its models run on its own API, Bedrock, SageMaker, Azure AI Foundry, Oracle OCI, any VPC or fully on-prem, with fine-tuning inside that environment. Vertex pipelines, features and registries are Vertex-native, which creates real lock-in, and its pricing is split across many services and hard to forecast. Cohere's Command A+ pricing is not published either, so production use often starts with sales. Enterprises committed to Google Cloud get more from Vertex. Those that need one model vendor across clouds or inside their own data center should look at Cohere.

What Google Vertex AI and Cohere do

Google Vertex AI

Vertex AI is Google Cloud's enterprise AI platform. At Google Cloud Next on April 22, 2026, Google rebranded it the Gemini Enterprise Agent Platform with an agent-first structure, though the API endpoint and most docs still say Vertex. Model Garden offers 200+ models, including Google's Gemini 3.8 family, Anthropic's Claude models and open models like Gemma, alongside Imagen, Veo and Chirp for media and speech. Google's own TPUs sit underneath much of its first-party serving.

Example models: Gemini 3.8, Claude

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
