Changelog

2026-09-30 — Agent sessions, receipts and long-context prices

  • Rebuilt Agent sessions around tasks, models and individual request receipts (#322).
  • Added session activity views and subagent lanes (#327). These show gateway activity; local tools are outside the observation boundary.
  • Connected long-context pricing to cost calculation, request receipts and public model pages (#333). The actual tier depends on the configured model and lane.
  • Corrected sitemap modification dates to reflect actual content changes (#337).

These dates refer to changes merged into the source repository. A self-hosted installation's availability depends on its deployed version. Reconcile a session's costs using the exported details.

2026-05-28 — Usage metadata and cache fields

  • Added normalized cache usage fields for OpenAI-compatible responses: cached_tokens, cache_write_tokens, cache_write_5m_tokens, cache_write_1h_tokens, and cache_miss_tokens.
  • Added usage_capabilities to the model catalog so clients can discover reported and billable dimensions before sending a request.
  • Added GET /api/usage/requests/{request_id} for request-level usage, billing line items, provider raw cache fields, and routing metadata.
  • Documented Qwen/DashScope, DeepSeek, Anthropic, Gemini, OpenAI, and OpenRouter cache reporting differences.

2026-05-12 — Static docs return to the VPS

  • Restore Vocs as the active documentation app for docs.lazu.ai.
  • Serve docs as a standalone static nginx container.

2026-05-09 — OpenAPI reference cleanup

  • Keep packages/contracts/openapi/lazu-api-reference.v1.yaml as the source of truth.
  • Sync OpenAPI JSON/YAML into the docs public assets during build.
  • Keep the interactive reference available for request and response field checks.
