ZenMux Builder’s served-model list has grown well past the stored snapshot: the live supported-models dialog counts 155 text models on Starter and 171 on Max and Ultra (196 and 218 in the full list once image and video rows are included), where the stored roster named 16 of 140. Every one of those 16 is still served — nothing was dropped — and the roster now names eight more: the three flagships promoted to the chips (Claude Opus 5.5, GPT-6.1 Sol, Gemini 4 Argon) plus Kimi K3.1 Pro, MiniMax M3.1 Flash, Grok 4.7, Step 5 Preview and Claude Haiku 5.5. modelsMore is re-derived against those live text counts, so it moves from “+124 more” on every tier to “+131 more” on Starter and “+147 more” on Max and Ultra. Plan fees ($20 / $100 / $200), the Flow allowances (50 / 300 / 800 per 5-hour window), the bonus window resets and the 1 Flow ≈ $0.03283 anchor are all unchanged, and the MiniMax H3 rows the dialog also lists stay out — they emit video, not text.

The ZenMux public model catalogue published anthropic/claude-sonnet-5.5 on 2026-09-28 with $2 input / $10 output / $0.20 cached read, a $2.50 5-minute cache write and $4.00 for 1 hour, so the model joins the shared Builder model list that all three tracked subscription tiers render. ZenMux publishes no cache discount of its own; the row stores the catalogue figures.

- Price24 Sept 2026
Cache-provenance re-verify of the ZenMux Builder Plan’s per-model rows against the provider’s own model API: every cached read on the rule now traces to a cache-read figure ZenMux prints, and four rows were priced below it. ZenMux has no cache-discount structure — its cache reads are the vendor list rates — so the stored 0.9x (Kimi K3, MiniMax M3) and 0.7x (Qwen3.8-Max) rows were not a ZenMux discount and were corrected, input and output with them; GPT-5.6 Sol was storing its 272K-token tier instead of the base tier. Every other row matches the page exactly.

- Launch12 Sept 2026
ZenMux added to the catalogue: a Singapore-operated AI gateway whose Builder Plan sells a fixed monthly fee for a Flow quota (a currency-like usage unit accounting for tokens plus call overhead) on any OpenAI/Anthropic-compatible agent; premium model coverage rotates on the lower tiers.
