Thinking Machines Lab has launched the Tinker API with OpenAI API compatibility, challenging vendor lock-in. Developers can now integrate Tinker models, including the trillion-parameter Kimi K2 Thinking model, into OpenAI infrastructure. This move lowers switching costs for developers seeking alternatives. Tinker also introduces multimodal capabilities with Qwen3-VL, outperforming traditional models in low-data tasks. Tinker emerges as a full-stack competitor, offering massive reasoning models and integration freedom.
