Pairwise charts
All providers (table view)
Models
One row per model in the competitive arena. Providers counts the providers serving the model as shown on this page — the published set the charts and provider table draw from — while Ctx served and Floor $/M are the values context fidelity and price ×floor normalize to (the largest context and cheapest blended price across all of the model's arena endpoints, before this page's provider filters). A bold below 100% under % of spec marks a model whose advertised context window no provider actually serves. Unlike the provider table, these rows are not clickable — the model and weights links are the only interactive elements, so a click never changes chart emphasis.
Reading & caveats
- Price (× floor)
- Blended price at an assumed 10:1 input:output mix, divided per model by the cheapest endpoint's blend. 1.0× = that provider is the floor. Log scale, clamped at 8×.
- Context fidelity
- Endpoint context ÷ the largest context any provider serves for that model. Low values are cut-down deployments (8K–262K of a 1M-context model). A capacity signal that complements the measured speed index. The denominator is the largest context any provider serves, not the model's advertised spec — see the for the models where those differ (— of — today).
- Reliability
- 1-day uptime per endpoint, clamped below at 80%. Medians in scatter panels; full endpoint spread in curves and ECDFs.
- Speed index
- Endpoint p50 throughput ÷ the fastest endpoint p50 for that model, so 100% = the fastest host of that model, comparable across models. OpenRouter-measured over a trailing 30-minute window sampled once daily at pull time — routed production traffic, not a clean-room benchmark. Raw tok/s and p90 latency appear in tooltips and the table. Provider medians are suppressed when fewer than 3 endpoints and under half the catalog carry throughput data; endpoints without throughput are omitted from speed panels only.
- Curves
- In endpoint-level panels each provider's endpoints are sorted by the x-metric and connected — a profile across their catalog, not a time series.
- First parties
- Google, Amazon Bedrock, Azure, Anthropic, Alibaba appear via their own or licensed models; their 1.0× price index reflects single-source pricing power, not cheapness.
