Claude Opus 4.7 Speed Test — First Look at Performance Data
Real-time performance data for Claude Opus 4.7. How fast is Anthropic's latest flagship compared to Opus 4.6, GPT-4o, and Gemini?
Anthropic just released Claude Opus 4.7 — the latest version of their most capable model. We added it to ModelStats immediately and started pinging it every 5 minutes.
Here's what we're seeing.
What's New
Claude Opus 4.7 is Anthropic's flagship model update. It's the successor to Opus 4.6, which remains available alongside the new version. Sonnet 4.6 and Haiku 4.5 are unchanged — this release is Opus-only.
What We're Measuring
Every 5 minutes, we send Opus 4.7 a streaming request and measure:
- TTFT (Time to First Token) — how long until the model starts responding
- Total Latency — full round-trip time
- Throughput (Tokens/s) — how fast it generates output
- ITL (Inter-Token Latency) — streaming smoothness
- Error Rate — reliability
Early Performance Data
Check the live dashboard for the most current data — these numbers are from the first hours of monitoring.
Opus 4.7 shows improvements over 4.6 in early testing. TTFT and throughput are both trending better, though the magnitude of improvement will become clearer as we collect more data over the coming days.
How It Compares
The Anthropic lineup now looks like:
| Model | Role | Status |
|-------|------|--------|
| Claude Opus 4.7 | Flagship, most capable | New |
| Claude Opus 4.6 | Previous flagship | Still available |
| Claude Sonnet 4.6 | Balanced performance | Unchanged |
| Claude Haiku 4.5 | Fastest, cheapest | Unchanged |
Opus 4.7 competes directly with GPT-4o and Gemini 2.5 Flash on speed, though it's positioned as the quality leader rather than the speed leader.

Should You Upgrade?
If you're on Opus 4.6, the upgrade is a simple model ID change (claude-opus-4-6 → claude-opus-4-7). Monitor the performance data on ModelStats for a few days to see if the improvement justifies switching your production workloads.
