- Hosted model APIs callable by model name (e.g., nsfw-detector, text-generator)
- Official JavaScript client (npm package) and browser distribution (dist/deepai.min.js)
- API key authentication (deepai.setApiKey)
- Supports multiple input types: URL, literal text, and file upload
- Configurable generation parameters (example: width, height, grid size)
- Parameter constraints documented (width/height default 512; acceptable 128–1536)
- Simple call pattern: callStandardApi(modelName, params)
- Open-source repositories and research projects (DeepAI Research, Simverse) available on GitHub
- Integration-friendly: supports bundlers (webpack, browserify) and require('deepai') usage
Best for
- Content Creation for Social Media: Rapidly produce unique images, short videos, and music tracks from prompts for posts, ads, or short-form content without design tools.
- Product/Design Prototyping: Generate concept imagery and iterate visual ideas quickly from text prompts to prototype product aesthetics and UI illustrations.
- Developer Integration: Embed generation, moderation (e.g., NSFW detection) and conversational features into web or mobile apps via the REST API or JavaScript client.
- Voice Assistant Prototyping: Build spoken conversational agents that can both listen and speak, useful for voice interfaces, demos, and accessibility tools.
- Automated Moderation Workflows: Use prebuilt detectors (NSFW and others) to scan user uploads and automate content policy enforcement in platforms and communities.
- Synthetic Data & Research: Leverage DeepAI Research projects (e.g., Simverse) to generate annotated synthetic datasets for training and evaluating computer vision and multimodal models.
- Interactive Educational Tools: Create interactive lessons or creative exercises where students generate and edit images, compose music, or chat with research-capable assistants.
- Automated content moderation (NSFW detection) for images
- Text generation for articles, summaries or copy
- Image generation and configurable outputs for creative assets
- Synthetic dataset generation for computer vision and multimodal research (Simverse)
- Rapid prototyping of ML-enabled web and Node.js applications
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
- Provider proxy wrappers for OpenAI and Anthropic that automatically log and trace requests
- OpenTelemetry integration and OTLP/HTTP ingestion for third-party tracing sources
- Plugins: Claude Code tracing plugin and OpenClaw observability plugin (exports OpenClaw activity as OTEL GenAI traces)
