A daily email challenge that turns AI curiosity into practical, work-ready habits
A new short lesson lands in your inbox every weekday morning, so progress fits around a working day instead of competing with it.
Think with AI, build with AI and work with AI: a progression from fundamentals to automation to lasting habits, rather than a random tour of tools.
Each lesson asks you to use AI on something from your actual role, so you finish with artefacts and workflows you can keep using.
Structured rollouts bring the same curriculum to a whole organisation with accountability and shared momentum, arranged via a sales conversation.
One API key for hundreds of AI models from every major provider
Six hundred plus models for text, image, video, audio, transcription, embeddings, and reranking behind one OpenAI-compatible API.
Requests are rerouted to another provider on outages or rate limits by default, so you don't write custom retry logic.
The auto-router selects a model and provider per request using live marketplace performance and pricing data.
Track spend, tokens, and usage per model, provider, and team member in one place, including bring-your-own-key usage.

#1A community library of AI prompts and chatbots you can chat with instantly

Offers robust serverless inference and GPU clusters for open models, but features a narrower selection of proprietary models.
#3
The top AI news and how to apply it, in five minutes a day
Features adaptive LLM routing and automatic failover, but lacks OpenRouter's massive ecosystem of community-rated model endpoints.

Free courses, live events and community for building real AI skills
SpecialistDelivers exceptional inference speed and high-throughput performance for open models, but focuses primarily on hosted weights rather than multi-provider aggregation.

Free / Open-sourceProvides self-hosted and Python SDK control over 100+ LLMs, but requires setting up your own infrastructure.


SpecialistLow-cost serverless inference APIs for 200+ open models

One unified API for 100+ AI models, with insurance when output disappoints
One API for fast, cost-predictable inference on LLMs and multimodal models

Aggregates hundreds of foundation models and agentic tools under one endpoint, but lacks OpenRouter's community popularity and extensive prompt tuning.
