Kilo Code adds Sonnet 4.6 support

This is a solid product update, not a flashy launch, but it hits where AI coding tools actually compete: model freshness, provider flexibility, and workflow coverage. Kilo is leaning hard into the “open-source coding agent with broad model choice” position rather than tying users to one closed stack.

• –Multi-provider Sonnet 4.6 support matters because teams can route the same model through Anthropic directly, Bedrock, or Vertex depending on procurement, compliance, and latency needs
• –Kilo’s homepage pitch around 500+ models, BYOK, and standard IDE support makes this update feel consistent with the product’s broader anti-lock-in strategy
• –Shipping Sonnet 4.6 quickly helps Kilo stay credible against faster-moving AI coding rivals that compete on who exposes new frontier models first
• –The roundup also bundles review suggestions, new providers, and reliability fixes, which signals Kilo is improving the day-to-day agent workflow rather than just chasing benchmark headlines
