No usage/cost shown for DeepInfra provider (openai-compatible)

Description

When using DeepInfra (https://deepinfra.com/) as a provider, opencode shows no token usage and no cost in the TUI / stats / session sidebar. The same setup works correctly with Anthropic (Claude), DeepSeek and OpenRouter — usage and cost display fine there. DeepInfra is the only one that shows nothing.

Setup

DeepInfra is configured as an OpenAI-compatible provider (@ai-sdk/openai-compatible), baseURL https://api.deepinfra.com/v1, e.g.:

"provider": {
  "deepinfra": {
    "npm": "@ai-sdk/openai-compatible",
    "options": { "baseURL": "https://api.deepinfra.com/v1" },
    "models": { "deepseek-ai/DeepSeek-V4-Flash-0731": { "name": "DS Flash DI", "tool_call": true, "reasoning": true } }
  }
}

Expected

Usage (prompt/completion tokens, cached tokens) and cost are reported for the DeepInfra provider, like they are for OpenRouter/DeepSeek.

Actual

No usage / cost is shown for DeepInfra at all.

Environment

• opencode (OpenChamber UI)
• macOS
• Provider: DeepInfra via OpenAI-compatible adapter
