Instrument Specifications (as of Jan 2026)

Key metrics that define the Instrument

Every Instrument is defined by a set of metrics. At a high level:

• Performance / Intelligence

  A score on an independent benchmark such as an Artificial Analysis Intelligence Index that reflects reasoning ability and accuracy.

• Time to First Token (TTFT)

  Maximum allowed time from request to first streamed token. This is critical for interactive UX.

• Throughput

  Minimum tokens per second while streaming. This drives both UX smoothness and batch job completion times.

• Context Window

  Minimum number of tokens the model can accept as input. This determines how much content you can pass in a single call.

• Output Length

  Minimum number of tokens the model can generate in a single response for that Instrument.

• Uptime and Error Rate

  Reliability requirements that suppliers must meet to stay eligible.
