GPT-6 Astra
OpenAI · Proprietary · rank 2 · bench-align-v5
Canonical idgpt-6-astra
Access typeProprietary
Blended $/1M$20.0075% input / 25% output
Capability shape
Seven axes from the ranking source. A missing axis is drawn as a gap.
Runtime service evidence
Measured values with the date they were observed. Nothing is inferred from a sibling model or a provider claim.
Time to first token: latency to the first answer chunk (Artificial Analysis, via BenchLM). Reasoning models include thinking time, so values can run to tens or hundreds of seconds.
Evidence key: Observed
| Measurement | Value | Observed | Last good | Evidence |
|---|---|---|---|---|
| Time to first token | 334.04 s | 2026-09-17 | 2026-09-17 | |
| Throughput | 60 tok/s | 2026-09-17 | 2026-09-17 |
Regional or per-endpoint measurements appear only when the API supplies them; none are modelled here.
Endpoint and price matrix
Every published price component, including cache reads and writes.
| Component | USD | Evidence |
|---|---|---|
| Input / 1M tokens | $10.00 | |
| Output / 1M tokens | $50.00 | |
| Cache read / 1M tokens | $1.00 | |
| Cache write / 1M tokens | $12.50 | |
| Blended / 1M (75% input / 25% output) | $20.00 |
Self-hosted listingOpenAI's GPT-6 Astra model page lists $10.00 input / $1.00 cached input / $12.50 cache writes / $50.00 output per million tokens, a 1,050,000-token context window, 922,000 maximum input tokens, and 128,000 maximum output tokens. Prompts above 272K input tokens are charged at 2x input and cache rates and 1.5x output for the full request; Batch and Flex are 50% of Standard and Fast mode is 2x. The September 3, 2026 price sheet lists Astra at 2.5x GPT-5.6 Sol's current $4.00 / $20.00 rates.The rates above are a hosted price matched from another provider, not a first-party list price.
Workload-aware monthly cost example
10 conversations per day × 8 messages × 22 active days, 1200 input and 400 output tokens per message, no cache. This uses the same calculator as the cost simulator, so an unavailable applicable rate makes the example unavailable too.
Benchmark record
58 matched benchmark rows with their published value, unit, and provenance.

Lifecycle and limitations log
Lifecycle events the source associates with this model, plus what this profile does not claim.
What this profile does not claimValues are reproduced exactly as their sources published them, in the units those sources declared; none are converted, interpolated, or averaged across providers. Any field marked unavailable was attempted and not returned — the attempt timestamp is in each badge. Last attempted fetch for this model’s score: 2026-09-17 17:17 UTC.
