Deprecated is not discontinued

OpenAI's October 1 and October 14 notices distinguish deprecated from discontinued. The specified snapshots below remain callable until shutdown; use evaluated replacements for new integrations. Lifecycle checked October 15, 2026.

Fine-tuned derivatives of the five October 14 snapshots follow their base model's January 14 shutdown. This is not a retirement of every GPT-4 endpoint. Replacement recommendations require quality, request-contract and billing validation, not only a name swap. See OpenAI's deprecations and our lifecycle tracker. Existing catalogue prices are retained as historical references.

● Oct 23 / Dec 11 identifies separate scheduled sunset dates. GPT-4o and GPT-4o mini have specified still-callable snapshots ending January 14, 2027, as listed above; absence from this catalogue is not proof of an already-failed endpoint.

Current API billing scope

GPT-6.1 Sol cache reads are $0.10/M; the earlier GPT-6 Sol is $0.20/M. Above 272K input, rates for the full request double for input/cache and rise 1.5x for output. Batch/Flex are half Standard; Fast is 2x. GPT-6.1 Sol Ultrafast is now available as service_tier: "ultrafast", not a separate model. Its short-context input/cache-read/cache-write/output rates are $12/$0.60/$15/$60; long-context rates are $24/$1.20/$30/$90. Sol Ultrafast supports US and EU residency; Astra Ultrafast remains US/global only at $60/$6/$75/$300 short-context. Tier limits are separate.

GPT-5.6 Sol $4/$0.40/$20 is temporary promotional pricing available at least through November 21, 2026. List rates are $5/$0.50/$30; qualifying usage and legacy credits can differ. GPT-oss rows are older unverified third-party reference prices, not direct OpenAI quotes. Verify a named host before buying.

Which OpenAI Model Should You Use?

Match your use case to the right model and tier.

Chatbots & Customer Support

GPT-6 Luna for new integrations

OpenAI's migration target for deprecated GPT-5.4 nano is GPT-6 Luna. Nano remains callable until April 1, 2027; its $0.20/$1.25 rates are retained for existing-workload estimates, not a new-integration recommendation.

Content Generation & Marketing

GPT-5.4

Excellent balance of quality and cost at $2.50/$15.00. Produces high-quality long-form content, blog posts, and marketing copy with strong reasoning. 1.05M context; long-context rates may apply.

Data Analysis & Summarization

GPT-5.6 Luna

Modern 1.05M context at $0.20/$1.20. Ideal for analyzing large documents, summarizing reports, and processing structured data that doesn'''t fit in smaller windows.

Code Generation & Debugging

GPT-6 Sol migration target

GPT-5.3 Codex is deprecated but callable until April 1, 2027. OpenAI names GPT-6 Sol as its replacement; validate coding workflows before migration. The Codex $1.75/$14.00 rates remain in the catalogue for existing usage.

Complex Reasoning & Research

GPT-5.5

An older general model at $5.00/$30.00. Best for multi-step reasoning, complex analysis, and tasks requiring the highest accuracy. 1.05M context.

Bulk Processing & ETL

GPT-oss 20B

Open-weight model, not available through the direct OpenAI API. The displayed hosting rate is an older unverified reference, not a current vendor quote.
