Four new models in the picker

Four new frontier models are now available in the model picker.

#Choose the right model for the work

• Gemini 3.8 Flash: Fast multimodal work across research, coding, and everyday agents.
• Claude Fable 5.1: Long-running coding, deep codebase research, and complex knowledge work.
• GPT-6 Astra: Computer use, software engineering, and tool-heavy tasks.
• Muse Spark 1.3 Max: Agentic coding, scientific reasoning, and complex workflows.

Each model runs inside a full SPIRITT workspace with browser, terminal, files, memory, and integrations, so you can compare them on real work without changing how you work.
