• P tags rows whose rates rise with request size (↑272k); Enter opens a model
  card: list and tier rates, your share billed at long-context rates, model facts,
  and a cheaper route for open-weight models.
• Reasoning tokens bill at the published reasoning rate, not output (34 models).
• w offers chat models only; models list/MCP gain tier and card fields.
• Holding j/k stops on release (100 queued keys: 10.2 s overrun → 0.04 s).

Refreshes the bundled models.dev snapshot, so some estimates shift.

Summary by CodeRabbit

• New Features
  • Pricing views now show model cards with base and context-tier rates, reasoning rates, model details, usage estimates, and qualifying lower-cost alternatives.
  • Model catalog entries include reasoning prices and available context, release, knowledge-cutoff, output-limit, and model-type details.
• Improvements
  • Cost estimates now use published reasoning-token rates when available, falling back to output rates otherwise.
  • Repeated key presses are handled more smoothly in the terminal interface.
• Documentation
  • Updated pricing, catalog, and terminal-interface guides to reflect these changes.

Walkthrough

Pricing now retains model-card facts, tier rates, and reasoning rates, and exposes them through API, web, and TUI pricing views. Price cards show tier and usage information. The TUI also processes queued repeats of a held key before repainting.

Changes: Model pricing cards

Layer / File(s)	Summary
Catalog metadata and pricing calculations src/opentab/accounting/pricing.py, src/opentab/accounting/tiers.py, src/opentab/__init__.py, tests/_support.py, tests/test_pricing.py, docs/backends.md	Pricing catalog parsing validates and caches model-card facts and tier rates. New helpers expose card details and resolve reasoning rates. Cost calculations use the applicable reasoning rate.
API and web pricing data src/opentab/api/service.py, src/opentab/web/report.py, src/opentab/web/page.py, tests/test_service.py, tests/test_web.py, docs/programmatic.md	Model listings and price payloads include reasoning rates and available card fields. What-if and token-economics calculations use the dedicated reasoning rate when present, with output-rate fallback.
TUI and browser model cards src/opentab/tui/app.py, src/opentab/tui/renderer.py, src/opentab/tui/views/prices.py, src/opentab/web/page.py, tests/test_tui_prices.py, tests/test_tui_views_prices.py, docs/pricing.md	Price rows include card metadata and tier indicators. The TUI and browser display rate cards, usage exposure, model facts, and qualifying cheaper routes.

TUI repeat-key handling

Layer / File(s)	Summary
Drain repeated keys before repaint src/opentab/tui/app.py, tests/test_tui_bindings.py, docs/tui.md	The input loop processes queued copies of the current key before repainting, for up to 0.1 seconds. It saves a different key for the next paint; mouse and resize events bypass draining.

The remaining issues are a misleading model-card context value and outdated pricing guidance. They are bounded and do not prevent merging, but should be corrected.

Update the stale reasoning-rate statement.

Lines 71-72 say Gemini and Antigravity thinking tokens "are priced at the output rate". This PR changes that rule. reasoning_price() now uses the card's published reasoning rate and falls back to the output rate only when the card has none. The new text at lines 632-638 states the new rule, so the two sections now disagree.

📝 Proposed doc fix

Update the reasoning-token pricing statement in the section describing Gemini

rate, falling back to the output rate only when no reasoning rate is published.

- Line 5680: Update the card’s context_window value in the renderer to use only
the published catalog limit, rather than model_context_window(entry.bare), which
can return an estimate or default; if a fallback must be shown, label it as an
estimate.
