About Kimi API
What is Kimi API?
Kimi API provides access to Moonshot AI's large language models, including the flagship Kimi K2.5 - a native multimodal model with vision, thinking modes, and agentic capabilities. Built on the 1 trillion parameter Mixture-of-Experts architecture, K2.5 achieves open-source SOTA performance while maintaining competitive pricing. The API is fully compatible with OpenAI's SDK.
- Native Multimodal Quality: Kimi K2.5 supports both visual and text input natively, with thinking and non-thinking modes. Excels at agent tasks, coding, and visual understanding.
- OpenAI-Compatible API: Drop-in replacement for OpenAI API. Use existing SDKs and tools with api.moonshot.ai/v1 endpoint. Supports tool calls, JSON mode, and streaming.
- Automatic Context Caching: Built-in caching reduces input costs by 75%. No configuration needed - the system automatically caches repeated context for cost optimization.
When to Use Kimi API
Choose Kimi K2 for coding and agentic tasks where you need strong performance at budget-friendly prices. Use K2 Turbo for latency-sensitive applications, and K2 Thinking for complex multi-step reasoning.
Ideal for
- AI coding assistants and code generation
- Autonomous AI agents with tool use
- Complex reasoning and analysis tasks
- Cost-effective alternative to premium models
- Applications requiring web search integration
Not ideal for
- Applications requiring <100ms latency
- Use cases needing very long context (>256K tokens)
- Tasks requiring guaranteed deterministic outputs

Cost Optimization Features
Automatic Context Caching (75% Savings)
Cached tokens cost only $0.15/M vs $0.60/M for K2 models. Caching is automatic with no configuration needed. View 'context caching' costs in your console.
Web Search Integration ($0.005/call)
Enable $web_search tool for real-time information. Only charged when search is triggered. Search results count toward token usage in subsequent calls.
K2 Turbo High-Speed Mode
60+ tokens/second output (max 100 tok/s) for latency-sensitive applications. Higher per-token cost but faster completion reduces wait time.
Tiered Rate Limits
Rate limits scale with cumulative recharge: Tier 1 ($10) gets 50 concurrent requests and 200 RPM. Tier 5 ($3000) gets 1000 concurrent and 10,000 RPM.

6 Kimi API Cost Optimization Tips
Leverage Automatic Caching
Kimi's automatic context caching reduces input costs by 75% ($0.15/M vs $0.60/M for K2). Design prompts with consistent system messages and context to maximize cache hits.
Choose the Right K2 Variant
Use K2 0905 ($0.60/$2.50/M) for most tasks. Switch to K2 Turbo ($1.15/$8.00/M) only when speed matters. Use K2 Thinking for complex reasoning that justifies the output cost.
Use Context Length Wisely
kimi-latest auto-selects pricing tier by context: 8K ($0.20/$2.00), 32K ($1.00/$3.00), or 128K ($2.00/$5.00). Keep requests under 8K tokens when possible for lowest cost.
Optimize Web Search Usage
Web search costs $0.005 per call plus token costs for search results. Only enable $web_search when real-time information is needed. Search results add to input tokens in subsequent calls.
Scale Your Rate Limits
Recharge strategically to unlock higher tiers: $10 gets 50 concurrent/200 RPM, $100 gets 200 concurrent/5K RPM. Match your tier to actual throughput needs.
Monitor with CostGoat
Track Kimi API spending per model with CostGoat. Get alerts when cache hit rates drop, when K2 Turbo usage spikes, or when web search costs exceed thresholds.
