Source: Epoch AI — “AI Benchmarking Hub” (epoch.ai), CC-BY (Epoch AI). Some rows carry an upstream leaderboard (shown per row); Aider & Terminal-Bench are additionally Apache-2.0. Each benchmark measures a different thing on a different scale — rows are not comparable across domains, and a score is not a guarantee of quality on your task.
Capabilities Index
Epoch AI's cross-model capability re-fit · one comparable axis · not our measurementThe dot is Claude Fable 5; the whisker is its 95% CI; the firm tick is the peer median; faint ticks are every other scored model. Unlike a raw benchmark, the ECI axis is comparable across models — but it's a relative re-fit scale, so a model's exact position can shift when Epoch recomputes it.

Human preference (LMArena)

This is human preference — which answer people pick in a blind A/B — not a correctness or capability score, and adjacent ranks routinely overlap within their intervals.

| Gemini 3.1 Pro Preview | 76%-3 | $0.008 | −77% |
Deduped to one entry per model (cheapest offering), priced at the reference 1K-in / 500-out request. Filtered only on the benchmark score — a model with an unknown capability is never silently excluded. A lower price is only cheaper if quality holds on your task — that's what routing proves.
Pricing
| Input · fresh prompt tokens | $10.00 / M |
|---|---|
| Output · generated tokens | $50.00 / M |
| Cache read · cached-input hit | $1.00 / M |
| Cache write · 5-minute TTL | $12.50 / M |
| Cache write · 1-hour TTL | $20.00 / M |
| Reasoning · thinking tokens | unknown |
Reasoning tokens: no separate rate is published. Providers typically bill thinking tokens at the output rate ($50.00 / M) — which is what the estimator assumes, so an extended-thinking workload isn't silently undercounted.

Pricing from TokenTriage's resolved price artifact (TokenTriage resolved price artifact (internal/pricing/data/prices.json)); capability + model metadata is third-party (LiteLLM model_prices_and_context_window.json, models.dev). Unknown means unstated, not absent.
Prompt-cache break-even
reuse the same prefix ≥ 2 times and caching winsWriting a prefix to cache costs a premium, but each subsequent hit reads at $1.00/M instead of $10.00/M. For this model the crossover is 2 reuses — past that, the same prompt keeps getting cheaper. TokenTriage's semantic cache is built to cross that line for you.

Estimate a request
disjoint token buckets · input = fresh (uncached) tokensHow output length drives the bill

Point your existing OpenAI client at your TokenTriage host and pass the catalog key as the model. TokenTriage attributes the real cost per request and can route to a cheaper model once it's proven just as good on your traffic.
