    • OpenAI Deprecations page, entry "2026-10-01: GPT-5.3-Codex, GPT-5.1, GPT-5.4-Nano": "The following models are deprecated and will be removed from the API on April 1, 2027, with six months’ notice. Migrate to the recommended replacements before the shutdown date." Table row (Shutdown date | Model / system | Recommended replacement): "Apr 1, 2027 | gpt-5.4-nano | gpt-6-luna", so the recommended replacement is gpt-6-luna.

    • Availability stays available: the model is still listed on the OpenAI pricing page and stays in the API until the announced shutdown, so no retirement is recorded before April 1, 2027.

    About capability scores (Epoch AI)

    Capability scores: Epoch AI, 'Capabilities & benchmarking'. Published online at epoch.ai. Retrieved from 'https://epoch.ai/benchmarks' [online resource], epoch.ai/benchmarks. Accessed 2026-10-31. Licensed CC BY 4.0; values here are rounded to one decimal place and grouped into bands.

    The Epoch Capabilities Index (ECI) combines many benchmarks on a scale where Claude 3.5 Sonnet is 130 and GPT-5 is 150. Bands, on the displayed one-decimal score: Frontier 160+, Strong 150–159.9, Capable 140–149.9, Entry below 140. Each score has a 90% range; a range that crosses a band boundary is flagged. Models are not ranked: neighbouring scores often overlap.

    A benchmark is not your workload. Epoch's scores mostly reflect runs at the highest reasoning effort, which use more output tokens than default settings. Scores are dated and can shift between Epoch releases. A score belongs to the developer's model; a host listing shows the same model's score, but hosts may serve different versions or quantizations.

    How headline rates are chosen

    Headline rates use the directory's shared rule: the rate a buyer meets by default, chosen by billing, tier and context dimensions and never by price. Context caps, the bracket starting at zero and short-context variants are labeled; unverified availability is flagged and is not a service guarantee. Batch, off-peak and other variants remain in the details; ambiguous headlines stay unknown.

    No currency conversion is performed. Missing cache prices are unknown, not zero. Equal units do not establish equivalent models or service conditions. See the methodology and source register.
