Subscription plans stop inventing dollar amounts — GLM Coding Plan, MiniMax, Kimi and Qwen now read "included in plan". Adds Grok 4.6, Gemini 3.7 Flash and GLM-5.3, and halves a Gemini rate stored at double.

Added

  • Grok 4.6 (grok-4.6) — xAI's flagship reasoning model, 500K context,
    recommended for code. The xAI default deliberately stays on
    grok-build-0.1: 4.6 bills 2× input and 3× output, so it is opt-in via
    /model rather than a silent upgrade for everyone.
  • Gemini 3.7 Flash (gemini-3.7-flash) — 1M context, Google's current
    workhorse for coding and agents.
  • GLM-5.3 (glm-5.3) — 1M context, on the GLM Coding Plan. Z.AI publishes
    no per-token rate and its standalone API is still "coming soon", so the model
    carries no price at all rather than borrowing GLM-5.2's.
  • Gemini gains its medium thinking tier. /thinking now offers
    low · medium · high on Gemini instead of collapsing medium into high. Medium
    is Gemini 3.7 Flash's own default and the level Google recommends for agentic
    coding; it used to be dropped because Gemini 3 Preview rejected it, which
    has since been fixed.

Changed

  • Subscription providers no longer quote a price. Z.AI's GLM Coding Plan,
    MiniMax, Kimi's Coding Plan, Qwen's plans and the free ModelScope tier bill a
    flat fee or nothing, yet their tokens were priced at pay-per-use rates.
    /cost, /stats and the status bar now read "included in plan"; a session
    mixing both shows the metered figure plus a note. Token counts, context and
    the energy/water estimates are unchanged — those are measured.

Fixed

  • Gemini estimates were double. gemini-3.6-flash was stored at the
    post-promotional 1.50/7.50 rather than the 0.75/3.75 actually charged through
    2026-12-31, so every Gemini cost read 2× high. Both tiers step back up on
    2027-01-01; the table names the date.
  • Gemini 3.7 Flash was sent temperature. That generation removed the
    sampling parameters, and the rule that omits them was only consulted on the
    Anthropic request path — Google is served over the OpenAI-compatible one, so
    the guard never ran. The same fix closes a related gap where namespaced
    OpenRouter ids (google/gemini-3.7-flash, anthropic/claude-opus-4.8)
    slipped past it entirely.
