Summary
Kimi Code provides two models, Kimi K3 and Kimi K2.7, accessible via four model IDs in various clients. The recommended model, k3-256k, offers equivalent results within a 256k context while consuming approximately half the quota compared to k3 (1M).
Key Takeaways

- The Kimi K3 model has a context window of up to 1M, while the Kimi K3-256k model is limited to a 256k context window and reduces consumption.
- Switching from K3 (1M) to K3-256k requires manually compacting the context if it exceeds 256k to preserve key points and maintain session integrity.
- Different membership plans provide access to various models, context windows, and speeds, with higher tiers unlocking more capabilities.
