Three intertwined bugs caused every Cost-tab row to display \$0
even after the scraper started writing real token data:
1. **Lookup key mismatch.** ``_cost_usd`` looked up bare ``model``
but ``_DEFAULT_PRICES`` was keyed by ``provider/model`` — every
priced model silently missed. Fixed by adding ``_price_key`` and
a fallback chain: ``provider/model`` → bare ``model`` → ``_unknown``.
2. **SQL grouped by model only.** Same modelID served by two providers
(e.g. ``claude-opus-4-6`` via Anthropic direct vs a local proxy) at
different rates was conflated into one row. Fixed: ``GROUP BY model,
provider`` in ``_api_cost`` + ``provider`` returned in each row.
3. **Math convention mismatch.** ``_cost_usd`` did ``(tokens_in -
cached) * in_rate`` assuming ``tokens_in`` was total input. But
the scraper records ``tokens_in`` as OpenCode's ``info.tokens.input``
(fresh, non-cached), so ``tokens_in - cached`` went negative
whenever cache reads exceeded fresh input — which is the common
case with Anthropic prompt caching. Fixed: no subtraction; the
three populations bill at their three rates.
Pricing seeded for the 8 models the scraper has actually observed
(``_DEFAULT_PRICES`` corrected from stale Opus-3 numbers + new entries
for the Haiku 4.5 / GPT-5 family / CleverThis HF endpoints):
| Provider | Model | in | out | cached_in |
|--------------|---------------------------|-------|-------|-----------|
| local-claude | claude-opus-4-6 | 5.00 | 25.00 | 0.50 |
| local-claude | claude-sonnet-4-6 | 3.00 | 15.00 | 0.30 |
| local-claude | claude-haiku-4-5 | 1.00 | 5.00 | 0.10 |
| openai | gpt-5 / gpt-5-codex | 1.25 | 10.00 | 0.125 |
| openai | gpt-5-mini | 0.25 | 2.00 | 0.025 |
| openai | gpt-5-nano | 0.05 | 0.40 | 0.005 |
| CleverThis-* | (HF endpoints, advisory) | 0.50 | 1.00 | — |
Operators can override without touching code via
``.opencode/telemetry/prices.json`` (added; same keying convention).
``_load_prices`` now skips ``_comment`` / ``_last_updated`` /
``_sources`` metadata keys so docs in the JSON don't pollute the table.
Smoke against current ``llm_activity`` (3743 turns, 450 archives):
total USD over the lifetime window is now \$118.06, with all 8 models
showing as priced.
Tests pin all three regressions: provider-qualified lookup, bare-model
fallback, no-subtraction math, GROUP BY (model, provider), and the
metadata-key filter in ``_load_prices``.
