Deprecated Models

This page contains information about models that have been deprecated by their respective providers and are no longer available through AvalAI.

Important: GPT-5 Chat Tags Are No Longer Available

The following GPT-5 -chat model tags are now deprecated and no longer available through AvalAI. They are not overridden or automatically routed to base models. Requests using these IDs will fail, so you must update your integration to use the corresponding model name without -chat:

Deprecated modelUse instead
gpt-5-chatgpt-5
gpt-5-chat-latestgpt-5
gpt-5.1-chatgpt-5.1
gpt-5.2-chatgpt-5.2
gpt-5.3-chatgpt-5.3

Action required: Replace these deprecated IDs now. Use gpt-5, gpt-5.1, gpt-5.2, or gpt-5.3 directly, without the -chat suffix.

The latest GPT model family now consists of gpt-5.6-sol, gpt-5.6-terra, and gpt-5.6-luna. Among these, gpt-5.6-luna has the lowest pricing and offers high cost-value return.

Overview

When AI model providers deprecate models, they are no longer available for new requests. This page serves as a comprehensive reference for deprecated models and provides guidance on migration to supported alternatives.

Deprecation Lifecycle

OpenAI's official deprecation guidance distinguishes between legacy, deprecated, and shut down models or endpoints:

  • Legacy means the model or endpoint no longer receives active updates and should be treated as a migration candidate.
  • Deprecated means the provider has announced retirement and published a shutdown or sunset date.
  • Shut down means requests will no longer be served after the listed date.

OpenAI generally gives at least 6 months of notice for generally available models, at least 3 months for specialized GA variants such as chat, Codex, or deep-research snapshots, and much shorter notice for preview models. Other AvalAI providers may use different notice windows, so always treat provider announcements, this page, and the live /v1/models catalog as the source of truth.

Warning

If OpenAI recommends a replacement that is not yet enabled in AvalAI, choose the nearest supported equivalent from Model Selection, the provider page, or /v1/models instead of hard-coding an unavailable model ID.

Migration Playbook

Use this checklist before a shutdown date:

  1. Inventory usage: search code, prompts, config, queues, eval fixtures, and saved presets for deprecated IDs and aliases.
  2. Select supported replacements: prefer stable, non-preview model IDs in AvalAI; avoid -latest aliases for regulated or regression-sensitive workloads.
  3. Run side-by-side evals: compare quality, latency, cost, context-window usage, tool behavior, structured-output validity, and safety behavior.
  4. Ship behind controls: roll out through feature flags or per-customer configuration so you can revert quickly.
  5. Monitor the cutover: alert on 404, model_not_found, provider-routing errors, cost changes, and unexpected usage deltas.

Important Note on Model Naming

Best Practice: Always use stable model namespaces when they become available. When a preview model is first introduced (e.g., gemini-2.5-flash-image-preview), it may later be released as a stable version (e.g., gemini-2.5-flash-image). In such cases, it is strongly advised to migrate to the non-preview, stable version as soon as possible to ensure continued support and optimal performance.
