Frequently Asked Questions about KAT-Coder-Pro V2.5
How much does the KAT-Coder-Pro V2.5 API cost per 1M tokens?+
KAT-Coder-Pro V2.5 by Kwaipilot is priced at $0.5 per 1M input tokens and $2 per 1M output tokens. With prompt caching enabled, cached input tokens cost $0.05 per 1M tokens, and asynchronous Batch API requests receive a 50% discount.
Should I use a $20/month subscription or the KAT-Coder-Pro V2.5 pay-as-you-go API?+
A flat $20/month consumer subscription is predictable for daily interactive chat and manual coding. However, if you are building software, running automated workflows, or sending low-to-moderate volume with prompt caching enabled, the pay-as-you-go API is typically far more cost-effective and offers higher rate limits without manual UI caps.
How many words and pages fit in KAT-Coder-Pro V2.5's context window?+
KAT-Coder-Pro V2.5 features a 256K tokens context window, which equals approximately 192,000 English words or ~512 standard single-spaced pages in a single prompt. Its maximum output generation per turn is 16,384 tokens.
Can I run KAT-Coder-Pro V2.5 locally on my own GPU (Open Weights)?+
No, KAT-Coder-Pro V2.5 is a proprietary closed-weights model hosted by Kwaipilot. It cannot be downloaded for local GPU execution and must be accessed via Kwaipilot's official API or cloud platform.
Does Kwaipilot train on data sent to the KAT-Coder-Pro V2.5 API, and is commercial use allowed?+
API payloads are excluded from model training by default. License tier: Proprietary Commercial API (Kwaipilot Terms). Full commercial ownership of generated outputs. Supported deployment channels include: Kwaipilot Cloud API & Enterprise Endpoints.
How does KAT-Coder-Pro V2.5 perform on coding and reasoning benchmarks?+
KAT-Coder-Pro V2.5 achieves a composite Intelligence Index of 85/100, scoring 58% on SWE-bench Verified, 67% on GPQA Diamond, 81% on MMLU-Pro, and 1360 pts on Chatbot Arena Elo.
What is KAT-Coder-Pro V2.5 best used for?+
KAT-Coder-Pro V2.5 is best suited for: Autonomous coding agents, CI/CD automated repair, and large-scale code modernization. Assessment: A formidable specialized coding engine offering top-tier software engineering proficiency.

AI Glossary & Architecture Concepts
View full glossary →Key machine learning concepts and benchmarks relevant to KAT-Coder-Pro V2.5:
The basic unit of text that a language model processes, typically representing about 3 to 4 English characters or roughly 0.75 words. For example, the sentence "Artificial intelligence is fast" breaks down into about 5 tokens.
A standardized evaluation suite used to objectively measure and rank an AI model's capabilities across specific tasks — such as SWE-bench Verified for software engineering, AIME for competitive math, or MMLU for general knowledge.
The maximum number of tokens a model can consider at once — both the input it reads and the output it writes. A 1,000,000-token context window can hold roughly 750,000 English words in a single request.
An AI model trained via reinforcement learning to spend dynamic compute thinking through complex logic, math, and architectural problems before outputting a solution. Examples include OpenAI o1, o3, and DeepSeek R1.
A step-by-step reasoning technique where an AI model generates intermediate problem-solving thoughts before arriving at a final answer. Native reasoning models like OpenAI o3 and DeepSeek R1 use CoT to solve complex math and coding challenges.
The ability of a language model to recognize when an external capability is needed and output structured JSON arguments to invoke external APIs, databases, or terminal commands. The runtime executes the tool and passes results back to the model.
Benchmark scores, token prices, and rate limits evolve rapidly as AI labs release model updates. Always verify current specifications and pricing on the official provider documentation.
