	Google Vertex AI Agents	Izlo Agents
Tagline	Google Cloud's unified platform for building, deploying, and scaling enterprise AI agents and models.	Prompt management platform with version control, collaboration, and an API for production deployment.
Category	Agents	Agents
Pricing	Paid· Pay-as-you-go per-token billing (varies by model: Gemini 2.5 Pro ~$1.25/M input, $10/M output tokens). Training, fine-tuning, vector search, and deployed endpoints billed separately by compute/hour. Free tier via Google Cloud $300 credit for new accounts.	Paid· Solo $20/mo; Pro $25/user/mo; Enterprise $39/user/mo
Model	Gemini 2.5 (Pro/Flash/Nano), Imagen, Veo, Chirp, plus Model Garden (Llama, Mistral, Claude via partner)	Model-agnostic

Pros	Deep integration with BigQuery, Cloud Storage, and Google Workspace makes enterprise RAG straightforward Model Garden gives one API surface for Gemini, open-source Llama/Mistral, and partner models like Claude Agent Development Kit (ADK) is a genuinely capable code-first framework with multi-agent orchestration Enterprise controls (VPC-SC, CMEK, data residency, private endpoints, audit logs) are best-in-class Gemini 2.5 models offer very long context windows (1M+ tokens) at competitive per-token pricing Vertex AI Search handles chunking, embeddings, and hybrid retrieval as a managed service TPU access for training and fine-tuning is a real cost advantage over GPU-only clouds	Git-style version history and activity log for every prompt change Remix sandbox isolates experiments from production prompts REST API lets you swap prompts without redeploying the app Built for multi-user team editing, not just solo developers
Cons	Steep learning curve — IAM, service accounts, quotas, and regional endpoints trip up newcomers Console UX is fragmented across Vertex AI Studio, Agent Builder, and legacy AI Platform screens Pricing is opaque until you build it out; egress and vector-search costs surprise teams Locks you into Google Cloud; multi-cloud portability requires wrapping everything in your own abstraction Third-party models (Claude, Llama) often lag the vendor's own API on latest versions and features	No free tier; cheapest plan is $20/mo Stingy token allowance (5K/seat) for in-app testing Lighter on observability/analytics than Langfuse or Helicone Supported model providers not clearly listed on the site
