Providers

Same model, different providers. Automatic routing spreads requests across healthy providers by default, or ranks them by price, latency and more.

Availability

24 hours · 10/21–10/22

Success rate of requests sent by the Amux AI gateway to each provider. Client errors are excluded.

Tok/s

24 hours · 10/21–10/22

Average output speed of streaming requests, in tokens per second (TPS).

TTFT

24 hours · 10/21–10/22

Average time to first token (TTFT) of streaming requests, measured from request dispatch to the first token received.

Activity

24 hours · 10/21–10/22

Relative request activity over time, broken down by serving provider. Indexed to the peak within the selected range (= 100); reflects trends and provider share, not absolute volume.

OpenAI: GPT-6.1 Sol1.05M contextfrom $0.1 / M tokens2 providersGPT-6.1 Sol is an upgrade to GPT-6 Sol from OpenAI, positioned below the flagship GPT-6 Astra in the GPT-6 series. It is suited for agentic coding, computer use, document-heavy professional work, and multi-step business workflow automation, and approaches Astra-level results on these tasks at a much lower cost. Compared with GPT-6 Sol, it makes fewer factual errors and is more reliable at respecting explicit restrictions and user intent during agentic tasks.
OpenAI: GPT-6 Luna1.05M contextfrom $0.01 / M tokens2 providersOpenAI: GPT-6 Luna is a fast and cost-effective model in the OpenAI GPT-6 series, positioned lower than GPT-6 Sol. It is suitable for high-concurrency and latency-sensitive workloads such as chat, classification, and lightweight agent tasks; at higher inference workloads, it can take on complex software engineering and computer usage tasks that previously required Sol-level models. It shares the improvements in factual reliability of the GPT-6 family, as well as a clearer, more concise communication style.
OpenAI: GPT-6 Sol1.05M contextfrom $0.1 / M tokens2 providersOpenAI: GPT-6 Sol is a cost-effective high-end model in the OpenAI GPT-6 series, positioned below the flagship GPT-6 Astra and above the fast GPT-6 Luna. It is suitable for demanding professional work, agency coding, business workflow automation and computer use, and is particularly good at long-span software engineering tasks in real code bases. It delivers near Astra-level reliability at a fraction of the cost and continues Astra’s clear, concise communication style in technical and programming conversations.
