Changelog

The newest release — quality-of-life and intelligence upgrades across the app.

• Faster AutoML — a rebuilt engine with a Fast / Full-accuracy switch: Fast ranks models on a sample for a quick answer, Full trains on every row for maximum precision.
• Live AutoML progress — a real progress bar and per-model checklist show what's done, what's training, and what's left.
• Whole-dataset AI — Aryabhata now understands your entire dataset (per-column stats, correlations, first & last rows), so it answers questions about all your data, not just a sample.
• OpenRouter support — added as an AI provider, alongside OpenAI, Groq, Gemini, xAI, Mistral, Anthropic-compatible and local Ollama.
• Better filtering & charts — the global categorical filter now shows searchable, selectable values on large columns, and distribution charts have cleaner percentage labels.
• Self-scrolling AI chat — long conversations scroll inside the chat panel instead of stretching the page.

ATARS began in February 2026 and has grown into the complete, no-code analytics platform you use today. Everything below is available right now.
