gpt-5.6-lunaClaude Sonnet 5 is the next generation of Anthropic's Sonnet model family. It is a drop-in upgrade for Claude Sonnet 4.6 with three behavior changes: adaptive thinking is on by default, manual extended thinking now returns a 400 error (it was deprecated on Claude Sonnet 4.6), and setting sampling parameters (temperature, top_p, top_k) to non-default values returns a 400 error
GPT-5.6 Luna is designed for cost-sensitive, high-volume workloads. It roughly corresponds to the nano model tier used in earlier GPT-5 families.
Prices are per million tokens. Latency and throughput are rolling averages measured on AIHubMix.
Promotional prices show the discounted rate; see each model page for promotion windows.
Daily traffic served through AIHubMix — how demand for each model is trending.
Measured on real AIHubMix traffic, hourly buckets. Gaps mean no traffic in that hour.
Estimate your monthly bill for the same workload on each model.
Monthly = daily × 30. Discounted rates applied where a promotion is active.
gpt-5.6-luna: $1.20/M output tokens; claude-sonnet-5: $10.00/M. Use the cost calculator above to estimate your own workload.
gpt-5.6-luna: 3.1s first-token latency measured on AIHubMix; see the live performance charts above for how each model behaves across the day.
claude-sonnet-5 accepts 1,000,000 and gpt-5.6-luna accepts 1,050,000 input tokens. Maximum output per request is 128,000 tokens on claude-sonnet-5 and 128,000 tokens on gpt-5.6-luna.
gpt-5.6-luna at 93.6 tokens/s and claude-sonnet-5 at 91.0 tokens/s, measured as output throughput on AIHubMix — a separate metric from first-token latency.
claude-sonnet-5 accepts text and image input and supports thinking, tool calling, function calling and structured outputs; gpt-5.6-luna accepts text and image input and supports tool calling, thinking and structured outputs.
Yes. AIHubMix serves every model on this page behind one OpenAI-compatible endpoint, so switching between them is a one-line change to the model field — no second account, key or SDK.
