- Works with regional Vertex AI deployments (EU / UK compatibility noted)
Best for
- Prompt engineering and rapid prototyping: Iteratively design and test prompts and conversational flows for Gemini, then package prototypes into small applets or demos.
- Custom fine-tuned models for domain tasks: Fine-tune Gemini models on proprietary datasets (text, images) to improve performance on customer support, legal summarization, or specialized classification.
- Multimodal interactive apps: Build applications that combine video/audio/image understanding with text reasoning (e.g., video event exploration, spatial mapping with embedded maps) using starter applets and LiveAPI.
- Tool-enabled assistants: Create assistants that execute functions, call external APIs (like Maps Embed), run code, and ground answers with Google search or other tools for accurate, actionable outputs.
- Media generation and content creation: Generate and edit images or short video snippets using integrated media models (Imagen, Veo) for marketing, creative workflows, or automated asset creation.
- Enterprise deployment via Vertex AI: Move prototypes from Studio into managed, scalable production deployments on Google Cloud Vertex AI for enterprise-grade reliability and compliance.
- Rapid prototyping of LLM-powered apps and agents
- Fine-tuning base models for domain-specific tasks
- Building spatially-aware applications (2D/3D reasoning, video event exploration)
- Integrating LLMs with external services (maps, embeds, other APIs) via function calling
- Educational tutorials and starter projects for developer onboarding
- Local development and testing of Gemini-powered frontend apps
PromptLayer
PromptLayer
Token-economics and observability platform to trace requests, monitor token usage and AI spend, and debug LLM workflows from one dashboard.
Key features
- Request Tracing: Captures structured traces for prompts, model inputs/outputs, tool calls and multi-step agent execution to visualize end-to-end LLM workflows and identify failure points.
- Token & Spend Analytics: Aggregates token usage and monetary spend across requests, models, features, and customers to enable cost attribution, budgeting, and optimization.
- Provider Proxies & SDKs: Official Python and Node.js SDKs and provider proxy wrappers (OpenAI, Anthropic, etc.) that automatically log requests, responses, and metadata for minimal instrumentation effort.
- Workflows & Replay: Helpers for running and replaying prompts and multi-step workflows, enabling regression testing, deterministic re-runs, and comparison of outputs across model versions.
- OpenTelemetry & Plugin Integrations: OTLP-compatible integrations and plugins (e.g., OpenClaw, Claude plugins) to export GenAI semantic traces and integrate with distributed tracing pipelines.
- Grouping, Annotation & Evaluation: Request grouping, metadata tagging, and robust evaluation/regression sets to organize requests, annotate outcomes, and track prompt performance over time.
- Self-Hosted Deployment: Full self-hosted stack (dockerized services with PostgreSQL, object storage, Redis) for teams needing on-prem data control, SOC 2/HIPAA/GDPR alignment and compliance.
- Request tracing and distributed traces for multi-step LLM workflows (OTLP/HTTP JSON compatible)
- Token usage tracking and AI spend monitoring with per-request and aggregated metrics
- Cost attribution to features, workflows, or customers
- Prompt/version management: template retrieval, listing, publishing, and cache invalidation
- Prompt/agent evaluation tooling, regression sets and replay capabilities
- SDKs for Node.js and Python with async support and promise-style or async methods
- Client methods: run/runWorkflow (helpers), logRequest (manual logging), track (annotations/metadata/scores/groups), group creation, wrapWithSpan/traceable decorator for instrumenting code
