  1. Model

    ElevenLabs v3 — emotional TTS, plus a dedicated compat endpoint

    POST /v1/audio/speech and the new POST /v1/el/tts now accept model: "eleven_v3" for ElevenLabs’ newest model — inline audio tags like [excited] or [whispers] shape delivery (5,000-char limit per request, vs 10,000 for the default eleven_multilingual_v2). Unrecognized model values now return a clear 400 instead of silently generating with the wrong model. Also fixed: POST /v1/tts/generate (the slug-based legacy path, e.g. slug: "luc4") had been pointing at a retired backend and always failing — it now runs on the same ElevenLabs gateway as everything else. Verified against production with real audio for both models.

  2. Pricing

    Gemini pricing update

    The default gemini-flash now maps to Gemini 2.5 Flash-Lite at 3 / 12 AP per 1K tokens (input / output) — lighter and cheaper for high-volume work. A new gemini-3.6-flash is added at 45 / 225 AP for top-quality reasoning. All rates follow our cost×3 policy.

  3. Model

    Kimi-K2.7-Code (Powered by Sakura AI Engine)

    A coding-specialized model — kimi-k2.7-code. OpenAI-compatible and verified working in OpenCode (v1.18.9) through api.aicu.ai. Also works from Cline and Continue. Free during public preview; domestic inference, no training on your data.

  4. Platform

    API keys required · reasoning models improved

    All /v1 endpoints now require a Bearer API key (issue one in the dashboard; public listing endpoints stay open). Reasoning models (gpt-5*) now honor reasoning_effort (minimal/low/medium/high) and default to minimal when unset, so short prompts return content instead of spending the budget on reasoning tokens.
