Kwaipilot's mid-tier model. Context window: 256K tokens.
Scores by test
Methodology →What you need to know
KAT-Coder-Air V2.5 is optimized for agentic workflows and large-scale data processing, distinguished by perfect scores in tool calling, agentic planning, and faithfulness. With a 256K context window and a 5/5 rating for long context handling, it is designed for tasks requiring high retrieval accuracy across massive datasets without losing coherence or hallucinating.
The model is priced aggressively for its capability set, with a blended cost of $0.487/MTok. This makes it a high-value option for developers who need advanced agentic capabilities and multilingual support without the premium pricing typically associated with top-tier proprietary models.
Performance degrades significantly when the model is required to follow strict formatting constraints. A 2/5 in constrained rewriting and a 3/5 in structured output indicate that it struggles with rigid syntax requirements or precise text manipulation. Developers should expect inconsistencies when requesting specific JSON schemas or strict character-limited outputs.
Use this model for autonomous agents, complex tool-use pipelines, and analyzing large documents. Skip this model if your primary requirement is strict structured data generation or precise, constrained text rewriting.
