🚀 ChatLima v0.41.0 - Marketing Site, Image Generation & Chat Refactor

🎯 What's New

  • Marketing homepage — new public landing experience with ChatLima moved to /chat for a clearer product/marketing split.
  • Image generation — generate images in chat with model selection, cost visibility, download support, and credit-based billing integration.
  • MarketingShell layout — consistent marketing layout and accessibility improvements across homepage, pricing, and related pages.
  • OpenRouter Fusion support — Fusion and meta-router models work in chat with dedicated 50-credit-per-message billing.
  • MiniMax M3 presets — preset manager support for MiniMax M3 with updated max-token handling.
  • Smarter sign-in redirects — Google OAuth sign-in returns users to their intended page after authentication.
  • Cyberpunk theme fixes — code blocks and tables are readable again in the cyberpunk theme.
  • Clearer pricing copy — credit-based plan usage messaging is easier to understand on marketing and billing surfaces.

🔧 Technical Implementation

  • Decomposed POST /api/chat into modular lib/chat/* services for stream setup, finalization, and route orchestration.
  • Added client-side message persistence and improved chat stream finalization with createdAt on AI/chat UI messages.
  • Introduced image generation tool handling, model validation, cost integration, and UI components (image-modal, textarea cost visibility).
  • Added marketing routes and MarketingShell component; integrated across multiple pages for shared layout/SEO structure.
  • Extended chat routing for OpenRouter Fusion/meta-router model IDs and billing pre-checks.
  • Updated docs/architecture/flows.json, flow explorer, SPEC.md, and README for subscription tiers, credit pricing, and the chat refactor.
  • CI: Neon PR branch schema push is now non-interactive.
  • Dev: added docs:flows script and Codex worktree setup helpers.

🛡️ Security & Privacy

  • No new required environment variables for production.
  • No database migrations required.
  • Image generation and Fusion model usage remain credit-gated with pre-check validation.
  • Auth redirect support preserves intended destination without exposing sensitive state.

📈 Benefits

For Users

  • A polished marketing site explains ChatLima before sign-in; chat lives at a dedicated /chat URL.
  • Generate images directly in conversation with transparent cost handling.
  • Fusion/meta-router models are usable without routing errors.
  • Cyberpunk theme users get readable markdown tables and code blocks.
  • Sign-in no longer drops users on a generic page after OAuth.

For Platform Operators

  • Modular chat pipeline is easier to maintain and extend.
  • Fusion billing is explicit (50 credits/message) rather than ambiguous token-based estimates.
  • Marketing and product surfaces are separated for better SEO and onboarding.

For Developers

  • lib/chat/* modules clarify responsibilities previously buried in the monolithic chat route.
  • Architecture flow docs and SPEC updates reflect the refactored chat pipeline.
  • Expanded type safety for image generation models and API key provider checks.

🔄 Migration Notes

URL Change

  • The main chat UI is now at /chat. Bookmarks or integrations pointing at / for chat should be updated.

No Breaking API Changes

Existing chats, accounts, billing, and provider integrations continue to work.

For Developers

  • Run pnpm install after pulling.
  • No new required environment variables.
  • No database migrations.
  • Review SPEC.md and docs/architecture/flows.json for updated chat architecture.
