Kimi
// Description
// Use Cases
- Free AI chat
- Frontier-level coding
- Long documents (1M context)
- Parallel agent research (Agent Swarm)
Kimi is the insider tip among Chinese models for coding: K2.6 plays in the frontier league on programming tasks, yet is open and free in chat. Same house rule as DeepSeek and Qwen: no client data in the cloud chat; for GDPR scenarios self-host the open weights.
// Deep Dive
What is Kimi?
Kimi is the AI assistant by Moonshot AI, one of Beijing's leading AI labs. It broke through internationally in late 2025 when the K2 models suddenly matched the most expensive US models on coding benchmarks, as open weights. As of August 2026 the lineup has three tiers: the K3 flagship (July 2026, 1 million token context), K2.7 Code for programming and the K2.6 workhorse with 256K context.
Using it for free
Chat on kimi.com and the mobile app are free with K2.6. The Moderato plan at $19/month unlocks Deep Research, Kimi Code, Slides and Website tools. The API has no permanent free tier; a $1 top-up activates access.
API pricing and open weights
K2.5 costs $0.60 input and $3 output per million tokens, K2.6 sits at $0.95/$4, the K3 flagship at $3/$15. K2.6 ships open under a modified MIT license, so it can be self-hosted, the usual route when data must not go to China.
What sets it apart: coding and Agent Swarm
Two things distinguish Kimi. First, coding strength: the K2 series reaches frontier level on programming benchmarks at a fraction of the cost. Second, Agent Swarm mode (since K2.5): Kimi coordinates up to 100 parallel sub-agents for research and analysis tasks instead of working sequentially. K2.5 also added native vision via the MoonViT-3D encoder.
How it compares
Within the Chinese trio the split is clear: DeepSeek has the most radical free offering, Qwen the broadest model palette, Kimi the strongest coding reputation. Against ChatGPT and Claude, Kimi competes on price-performance and openness. Agent fundamentals: AI agent.
