Kinetic-4B wins on tool calling. On a 300-sample Composio evaluation, the 4-billion-parameter model from Bengaluru lab Conscious Engines scored 82.33% accuracy at 1.61s p95 latency, against 80.0% and 4.02s for Anthropic's Claude Haiku 4.5, and 76.33% at 7.99s for OpenAI's GPT-OSS-120B ( Conscious Engines, 1 April 2026 ). That is 2.5x lower tail latency at slightly higher accuracy. Haiku remains the better buy if you need one model to also write, summarise, reason and code; Kinetic-4B wins only t...
