Changelog

Context Engine now supports multi-document reasoning chains up to 2M tokens. Pass entire codebases, contract libraries, or documentation sets and KAIRO will reason across all of them simultaneously without losing thread.

What’s new

• Multi-document context windows up to 2M tokens
• Cross-document reference resolution — cite exact passages from any source
• Semantic deduplication automatically removes redundant context
• New context.attach() API for programmatic document injection

Migration

No breaking changes. Existing workflows benefit automatically from the larger context window.

Infrastructure optimization reducing p99 latency from 34ms to 18ms across all inference endpoints. No API changes.

Changes

• Edge caching layer deployed in 12 new regions
• Request queue optimization reduces tail latency
• Connection pooling rewrite for Model Router

The Workflow Builder is now generally available. Design multi-step AI automations on a drag-and-drop canvas without writing JSON configuration files.

Highlights

• Drag-and-drop node canvas with real-time preview
• 80+ pre-built action blocks covering the most common integration patterns
• Branch logic, loops, and conditional routing — all visual
• One-click deploy to production from within the builder
• Version history with diff comparison

Model Router now includes automatic cost optimization. Set a quality threshold and KAIRO routes each request to the cheapest model that meets your bar.

New capabilities

• Cost profiles: set target cost-per-request with quality floor
• A/B routing: split traffic between models to compare output quality
• Real-time cost dashboard with per-workflow breakdown
• Fallback chains: define ordered fallback if preferred model is unavailable

Privacy Shield is now enabled by default on all Scale tier accounts. Your data is processed in isolated sandboxes and never used to train shared models.

Architecture changes

• End-to-end encryption for all context data
• Isolated inference environments per tenant
• Data residency controls: choose EU, US, or APAC
• SOC 2 Type II certification completed
• BAA available for healthcare customers

KAIRO 2.0 is a ground-up rewrite of the platform. API v1 is deprecated and will be sunset on March 1, 2026.

Breaking changes

• /v1/ endpoints deprecated — migrate to /v2/ by March 1, 2026
• Authentication now uses API keys instead of OAuth tokens
• Webhook payload format updated — see migration guide
• SDK minimum version requirements updated

New in 2.0

• 10× faster Context Engine with multi-document support
• Unified API surface across all product areas
• Real-time streaming for all inference calls
• New TypeScript, Python, and Go SDKs
