📝 Walkthrough

Walkthrough

This PR upgrades the Kimi model version from K2.5 to K2.6 across documentation, component labels, pricing configurations, and model aliasing throughout the frontend. The K2.5 entry is removed from MODEL_CONFIG, and all aliases are updated to point to K2.6.

Changes

Cohort / File(s)	Summary
Documentation docs/support-faq.md, frontend/public/llms-full.txt, frontend/public/llms.txt	Updated model references from Kimi K2.5 to K2.6 in feature lists, model descriptions, and model availability documentation; also updated pricing table identifier from kimi-k2-5 to kimi-k2-6.
Component UI Updates frontend/src/components/Marketing.tsx, frontend/src/components/PromoDialog.tsx, frontend/src/components/UpgradePromptDialog.tsx, frontend/src/routes/teams.tsx	Updated user-facing display text and benefit descriptions to reference Kimi K2.6 instead of K2.5 across promo dialogs, upgrade prompts, and model badge listings.
Model Configuration frontend/src/components/ModelSelector.tsx	Removed the hardcoded Kimi K2.5 entry from MODEL_CONFIG, eliminating support for K2.5 model name resolution, vision capability checks, and token limit lookups.
Pricing Configuration frontend/src/config/pricingConfig.tsx	Updated pricing plan feature descriptions across Free, Starter, Pro, Max, and Team plans to reference Kimi K2.6 instead of K2.5.
Model Aliasing frontend/src/utils/utils.ts	Updated MODEL_NAME_ALIASES to normalize legacy aliases ("kimi-k2", "kimi-k2-thinking", "deepseek-r1-0528", and "kimi-k2-5") to resolve to "kimi-k2-6".

In `@frontend/src/utils/utils.ts`:
- Around line 82-85: The change in MODEL_NAME_ALIASES currently rewrites four
legacy aliases ("deepseek-r1-0528", "kimi-k2", "kimi-k2-thinking", and
"kimi-k2-5") to "kimi-k2-6"; decide and implement one of two fixes: either add a
clear migration note/comment (and a short changelog entry) next to
MODEL_NAME_ALIASES explaining the intentional retirement and
backward-compatibility implications and reference PAID_DEFAULT_MODEL_ID and
PRIMARY_MODELS.powerful as the only default controls, or restrict the alias
mapping so only "kimi-k2-5" -> "kimi-k2-6" is redirected while leaving
"deepseek-r1-0528", "kimi-k2", and "kimi-k2-thinking" untouched; update comments
to indicate why the chosen approach preserves MODEL_NAME_ALIASES stability.
