AI Models & LLMs

Claude

Claude consistently produces cleaner prose and more precise code than most competitors, but rate limits hit harder here than anywhere else in the market. Here is the full picture, including the incidents Anthropic would rather you forgot.

Vertex AI

Vertex AI is Google Cloud's enterprise AI platform for model training, deployment, and agentic workflows. It combines a 200-model garden including Gemini, Claude, and Llama with managed MLOps tools, but carries significant complexity and billing risks for teams outside the GCP ecosystem.

AI Models & LLMs

IBM watsonx

IBM watsonx.ai is IBM’s enterprise generative AI studio for Granite and third-party models, RAG, and agents. Free/Lite evaluates at up to 300k tokens/month; Standard starts at $1,110/month (official, indicative). Token rates such as granite-4h-small ~$0.0636/$0.265 per 1M are published on IBM’s pricing page.

AI Infrastructure

Vast.ai

Vast.ai is a peer-to-peer GPU rental marketplace where independent hosts list compute at market rates. H100s from ~$0.90/hr, RTX 4090s from $0.34/hr. Far cheaper than managed clouds, with tradeoffs on reliability and setup complexity.
