Cursor 3.1 shipped April 13, 2026 with a tiled Agents Window that runs multiple agents side by side and a rebuilt voice input pipeline. Here's what's actually useful, what's still annoying, and who should care.
A new agent memory paper from April 2026 argues that the dominant pattern — extract facts with an LLM, store the facts — bleeds truth and tokens. MemMachine stores the raw episodes instead, hits 0.9169 on LoCoMo, and spends ~78% fewer input tokens than Mem0.
A copy-paste promptfoo config that runs the OWASP LLM Top 10 against your prompt, compares two models, and fails your CI pipeline when quality regresses. Includes real YAML, real CLI output, and the three gotchas that bite on first run.
Common questions about AI tokens, pricing, and our tools
AI Tools Kit provides essential utilities for developers and content creators working with large language models like GPT-5, Claude 4.5, Gemini 3, and other AI systems. Our token calculator helps you understand exactly how your text will be processed by AI models, enabling you to optimize prompts and reduce API costs.
Accurately count tokens before sending requests to OpenAI, Anthropic, or other AI providers. Understand how tokenization works and see exactly how your text breaks down into tokens. Support for multiple models including GPT-5, GPT-4.1, Claude 4.5, and more.
Token Optimized Object Notation (TOON) reduces your JSON payload size by up to 50%, saving tokens and reducing API costs. Convert between JSON and TOON formats instantly with our free converter tool.
