v3.14.4 — expose all 8 z.ai GLM models z.ai serves 8 GLM models; aigate was only exposing 3. This release adds the missing 5 routes so the full z.ai catalog is reachable via pibox-zai aliases. No removals, no breaking changes. ADDED: - pibox-zai-glm-5.2 (newest flagship, released 2026-06-17) - pibox-zai-glm-5-turbo (fast tier) - pibox-zai-glm-5 (earlier 5-series) - pibox-zai-glm-4.6 - pibox-zai-glm-4.5 PIBOX_AVAILABLE_MODELS default expanded to all 8. QUOTA NOTE: z.ai bills the 5-series at 3x during Beijing peak (14:00-18:00) and 2x off-peak (1x under the current promo through end of September 2026). The 4-series bills at the flat 1x rate. Defaulting to glm-5.2 burns subscription quota ~3x faster than glm-4.7 during peak hours. docs/providers.md has the breakdown. Patch bump — additive provider audit. Smoke clean for all 5 new routes via litellm → pibox → z.ai.
