About this API

GPT-3.5 Turbo is OpenAI's fastest model. It can understand and generate natural language or code, and is optimized for chat and traditional completion tasks. Training data up to Sep 2021.

Provider-supplied description, not an independently validated performance claim.

Input / 1 million tokens$0.25Published prompt tariff

Output / 1 million tokens$0.75Published completion tariff

Context window16,385Published token capacity

These are the catalogue’s token tariffs. Image, audio, video, search and other charges may use different billing units. Zero token rates alone do not mean those services are free. See the complete pricing fields below and the source model page.

Pros and useful characteristics

Published input token pricing is at or below the median of catalogue entries with the same output modalities and known tariffs.
Published output token pricing is at or below the same-modality catalogue median.
No separate per-request fee is listed in this catalogue observation. Other modality charges may apply.
The upstream catalogue advertises tool-call parameters. This gateway does not expose them yet.

Cons and practical limits

The published context window is 16,385 tokens; larger documents may need splitting.
Trident Protocol currently limits requests to text content, 24 KB of conversation and at most 4,096 output tokens. Free variants remain subject to upstream rate limits and availability.
No independent latency, uptime, reasoning-quality or coding benchmark has been measured by this application.

Assessment uses published fields and unweighted price medians across 426 entries with the same output modalities and known tariffs. It is a cost-and-capability comparison, not a quality ranking or recommendation.

Observed price history

No observations yet. The chart starts with the first recorded data point.

One catalogue observation per hour. History begins when this deployment first observes the model. No backfilled or interpolated prices.

Complete published pricing

Source fields are retained exactly, including extra charges and tier overrides. Negative values indicate variable pricing, not rebates. An absent field is not evidence that a service is free.
