Quality
Known Good Index and the capability indices, side by side
Each index is min-max normalised across tracked models and scaled 0–100 from published evaluations. We do not run these evaluations.

Quality Breakdown
Every evaluation both models report a published score for
Bar = OpenAI: GPT-5 Mini · marker = OpenAI: o1 · scores ingested from Epoch AI (CC-BY 4.0)
Right-hand figures read OpenAI: GPT-5 Mini / OpenAI: o1. OpenAI: GPT-5 Mini leads on 3 of 4, OpenAI: o1 on 1.
Arena Elo
Human preference rating from blind pairwise votes
Elo from blind pairwise votes, ingested from Arena. Higher is better.
Neither model currently appears in an arena we ingest.
Price & Cost
Published API pricing by token type
USD per 1M tokens. Blended is a 3:1 input:output mix. Live from OpenRouter, cross-checked against models.dev. Lower is better.
| Metric | OpenAI: GPT-5 Mini | OpenAI: o1 |
|---|---|---|
| Input $/1M | $0.25 | $15.00 |
| Output $/1M | $2.00 | $60.00 |
| Blended $/1M | $0.69 | $26.25 |
| Cache read $/1M | $0.025 | $7.500 |
Context Window
Maximum input accepted and maximum output emitted
Provider-declared limits, from metadata via models.dev and OpenRouter. Higher is better.
| Metric | OpenAI: GPT-5 Mini | OpenAI: o1 |
|---|---|---|
| Context window | 400k | 200k |
| Max output tokens | 128k | 100k |
Speed & Latency
Median throughput and time to first token across hosting providers
Medians across all tracked providers, derived from OpenRouter endpoint telemetry.
| Metric | OpenAI: GPT-5 Mini | OpenAI: o1 |
|---|---|---|
| Output tokens/s | 100 | 24 |
| Time to first token | 3.3s | 1.4s |
Providers
Which hosts serve each model, and at what price and speed
| Provider | OpenAI: GPT-5 Mini blended | OpenAI: GPT-5 Mini tok/s | OpenAI: o1 blended | OpenAI: o1 tok/s |
|---|---|---|---|---|
| OpenAI · first party | $0.34 | 142 | $26.25 | 13 |
| Azure · first party | $0.69 | 78 | — | — |
Per-host pricing and telemetry from OpenRouter. A dash means that host does not serve that model.
