How Many Spoons Does Your AI Coding Tool Cost?

AI coding agents can reduce developer effort, but vendor lock-in creates a hidden energy tax: teams get stuck on one vendor's model, can't benefit from faster-moving open-weight alternatives, and lose time debugging opaque failures. The open-weight model market is accelerating rapidly — Kimi K3 (2.8T parameters), DeepSeek V4 (MIT license), and Qwen 3.8-Max all shipped within days of each other, with open-weight models now 4–7 months behind closed frontier labs (down from 6–10 months) and accounting for ~45% of tokens on major routing platforms. Open-source agents that support bring-your-own-API-keys and multi-model routing let teams adopt new models without rebuilding workflows. Kilo Code is presented as an example: Apache-2.0/MIT licensed, supporting 500+ models with zero inference markup, available in VS Code, JetBrains, CLI, and cloud, with 3M+ developers and 40 trillion tokens processed.

How far behind are open-weight AI models compared to closed frontier models now?
The UK's AI Safety Institute measures the best open-weight models at four to seven months behind closed frontier labs on hard benchmarks, an improvement from six to ten months behind for most of the prior year, while running at a fraction of the cost of closed models. Anyone weighing open versus closed models for coding work can track these shifts on daily.dev.
What license does Kilo Code use and how many models does it support?
Kilo Code is open source under Apache-2.0 for its extension and MIT for its CLI, and it connects to more than 500 models with zero markup on inference. It runs in VS Code, JetBrains, the CLI, and the cloud, and has surpassed 3 million developers and 40 trillion tokens processed. Developers comparing AI coding agents can follow tool details like this on daily.dev.
What share of AI model tokens now come from Chinese open-weight providers?
Chinese open-weight providers account for roughly 45% of tokens flowing through major routing platforms, up from under 2% a year earlier. This shift followed releases such as Moonshot AI's Kimi K3 (2.8 trillion parameters, open-sourced in late July), DeepSeek V4 under an MIT license, and Qwen's 3.8-Max. Teams tracking the open-weight model race can keep tabs on trends like this via daily.dev.
