Price receipt
Historical price.This model is retired — withdrawn on — so the provider no longer sells it and its page can no longer confirm this number: a price for a model no longer on sale is unconfirmable by definition, not missing. The figures above are the last prices we recorded for this model, kept as a historical record rather than a live quote.
Overview
Retired from the OpenAI API on 2026-08-10; requests to it there now fail. Chat-tuned GPT-5.3 (the GPT-5.3 Instant snapshot used in ChatGPT) with a 128K context, last listed at $1.75/$14 per 1M tokens. Use GPT-5.6 Sol instead.
Capabilities
struck through = not supportedBenchmark performance
accuracy % · higher is betterWe hold no per-benchmark accuracy scores for this model yet, so it has no accuracy average. That is a gap in our coverage, not a sign the model is untested — independent evaluators often publish a composite index for a new model long before releasing its per-benchmark numbers. The percentile above is its standing across the independent composites below.
