Standalone agent-first platform with CLI, SDK, and managed agents
AI-powered IDE built as a fork of Visual Studio Code, designed with an 'agent-first' paradigm where autonomous AI agents plan, execute, and validate code
Why: Antigravity 2.0 is Google's most credible bid for the agentic IDE seat. The new CLI and SDK make it competitive with Cursor, Claude Code, and Codex for terminal-first and automation workflows.

Anthropic's frontier model, currently first on the Artificial Analysis Intelligence Index
Claude Opus 5 is Anthropic's flagship model, released 24 July 2026 with a 1M-token context window and five selectable effort levels (low, medium, high, xhigh, max)
Why: It is the current number one on the independent Artificial Analysis Intelligence Index, and it got there while costing less per task than the model it displaced: $2.03 average per index task against Fable 5's $2.75. The effort dial is the reason to pick it over a fixed-tier model, because one integration covers cheap high-volume calls and expensive long-horizon agent runs.

The AI-native IDE that redefined software engineering
Cursor is a fork of VS Code built specifically for AI-pair programming
Why: Cursor is a special coding tool that actually 'reads' your entire folder of files. Imagine having a partner who remembers every single line of code you've ever written and can tell you exactly where a bug is hiding. It's the top choice for developers because it makes building apps 10 times faster by doing the boring 'search and find' work for you.
