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.

The Invisible OS: Pure Execution via Messaging
Moltbot (also known as Clawdbot) is the spearhead of the 'Invisible OS' movement, a shift away from fragmented apps and toward pure, autonomous execution via messaging
Why: Moltbot represents the death of the 'app for everything' era. We picked it because it's the first agentic assistant to prove that reasoning-based execution through simple chat is more powerful than manual task management in 10+ different apps.

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.

About Meta Muse Glimmer
Muse Glimmer is Meta's 30 billion parameter open-weight model released August 2026, designed to run autonomous AI agents directly on consumer hardware without cloud dependency. It ships under the permissive Apache 2.0 license (Meta's first fully open release since moving to proprietary Muse Spark in April), quantized to roughly 4 bits with block-level speculative decoding for fast local inference. Drops the 700M monthly user restriction that hampered prior Llama releases.
