announce-cost

# Announce BlockRun cost before charging The BlockRun media tools spend real USDC per call. The client's confirmation dialog does not reliably show the cost, so **you must surface it yourself**. **Before every paid `blockrun_*` call**, write one short line in your reply stating the model and the estimated cost, then make the call. Example: > Generating with **cogview-4** — estimated **~$0.015**. (Approve the prompt to proceed.) Do this for `blockrun_image`, `blockrun_video`, `blockrun_music`, `blockrun_speech` (speak / sound_effect), and `blockrun_realface` (enroll / portrait). Free actions need no announcement: `blockrun_wallet`, `blockrun_models`, `blockrun_speech` action `voices`, `blockrun_realface` actions `list` / `init` / `status`, and crypto/fx/commodity `blockrun_price`. If the user asked for several images/clips at once, announce the **total** (per-item cost × count) before starting. ## Estimated pricing (USD) **Image** (`blockrun_image`, 1024² base; `hd`/larger sizes cost more): | Model | ~Cost | |-------|-------| | `zai/cogview-4` | $0.015 | | `xai/grok-imagine-image` | $0.02 | | `openai/gpt-image-1` | $0.02–0.04 | | `google/nano-banana` | $0.05 | | `xai/grok-imagine-image-pro` | $0.07 | | `openai/gpt-image-2` (default) | $0.06–0.12 | | `google/nano-banana-pro` | $0.10–0.15 | **Video** (`blockrun_video`, per second × duration): | Model | ~Cost/sec | |-------|-----------| | `bytedance/seedance-2.0-fast` | $0.05 | | `bytedance/seedance-1.5-pro` | $0.09 | | `bytedance/seedance-2.0` | $0.12 | | `xai/grok-imagine-video` (default) | $0.10 | | `azure/sora-2` | $0.10 | e.g. `grok-imagine-video` 8s ≈ $0.80; `seedance-2.0-fast` 5s ≈ $0.25. **Other:** `blockrun_music` ≈ $0.02/track · `blockrun_speech` TTS ≈ $0.07/1k chars, sound effect ≈ $0.0525 · `blockrun_realface` enroll/portrait ≈ $0.01 · paid stock `blockrun_price` ≈ $0.001. These are estimates to inform the user; the gateway settles the exact amount.
