Follow the consequence of a change through to the advice you use. Each entry keeps vendor announcements, source reviews and actual workflow tests distinct.
This pilot covers 10 advice pages and five named workflows. A test result applies to its stated recipe.
Verified-advice pageview measurement starts 2026-10-20. Source-reviewed reach and workflow-tested reach are measured separately. Inspect pilot evidence.

These are observed provider recommendations. A held replacement does not invalidate a documented retirement date. Dates retain their earliest-possible or tentative qualification; a passed date does not establish a runtime shutdown.

Reviewed OpenAI, Claude and Gemini model prices are checked automatically. Claude rates require agreeing pricing/cache tables. Gemini observations cover paid Standard uncached text only; cached and token-hour storage estimates are excluded. The shared calculator retains its separately reviewed catalog; current admitted presets appear in the integration status.

Anthropic confirms that claude-opus-4-1-20250805 retired on August 5, 2026 and Claude API requests return an error. Its retirement release note recommends Claude Opus 5, while its current deprecation table recommends claude-opus-4-8; the recommended replacement is inconsistent across official sources.
Anthropic released Python SDK v1 on August 20 with Python 3.10+, httpx2, removed legacy APIs and sampling parameters, async raw-response parsing changes, and stricter AnthropicBedrock region handling.
Starting with the April 16, 2026 launch of Claude Opus 4.7, non-default temperature, top_p, and top_k values return HTTP 400; Anthropic recommends omitting them and using prompting.
In Python 1.2.0, TypeScript 0.122.0, Go 1.68.0, Java 2.59.0, Ruby 1.67.0 and C# 12.44.0, beta Files/Skills clients stop sending legacy beta headers and return stable shapes. The change also makes client.beta.skills.delete() delete the Skill and all versions, and renames BetaSkill to BetaContainerSkill. Explicit requests retaining the beta headers keep beta shapes.
Google currently lists no shutdown date or recommended replacement for the stable gemini-2.5-pro model. Kingy has withdrawn its earlier October 16 retirement claim.
Google’s current deprecation table lists October 22, 2026 as the earliest possible shutdown date for gemini-omni-flash-preview, with gemini-omni-1.1-flash as replacement. The August 27 release note describes September 30 as deprecation. The historical September 30 shutdown observation is retained; current runtime availability remains untested.
Google's Gemini Robotics ER 1.6 shutdown date passed August 31; current service state unconfirmed.
Google’s July 21 announcement deprecated sampling parameters for the new models released then. The moving latest-model guide now covers Gemini 3.8 Flash and its migration checklist; it cannot independently re-verify historical Gemini 3.7-specific behavior.
Google’s current lifecycle table retains August 17, 2026 as the shutdown date for three Imagen 4 API model IDs and now recommends gemini-nano-banana-2.1. Preserve the earlier gemini-3.1-flash-image recommendation as dated history; account/runtime and migration results remain untested.
OpenAI has scheduled Agent Builder to shut down on November 30, 2026. Export and test a migration to the Agents SDK or a suitable Workspace Agent; ChatKit remains available.
OpenAI says the Assistants API was officially sunset on August 26, 2026 and is no longer available. Remaining integrations must move to the Responses API; Conversations provide durable state where needed.
OpenAI lists gpt-5.2-chat-latest and gpt-5.3-chat-latest under past deprecations after their August 10, 2026 removal date and recommends gpt-5.6-sol.
OpenAI lowered GPT-5.6 Sol Standard pricing on August 21, 2026. For prompts up to 272K input tokens, the uncached input/output rates are $4/$20 per million tokens; longer prompts cost $8/$30 for the full request. The promotional guarantee extends at least through November 21.
OpenAI schedules gpt-image-1-mini, gpt-image-1.5 and chatgpt-image-latest for API removal on December 1, 2026. Its current deprecation table recommends gpt-image-2.5-sunburst or gpt-image-2.5-flare.
OpenAI will remove whisper-1, gpt-4o-transcribe, gpt-4o-mini-transcribe and gpt-4o-transcribe-diarize from the API on February 26, 2027.
OpenAI lists September 24, 2026 as the shutdown date for the Videos API and the five named Sora IDs. That date has passed; current service availability remains unconfirmed, and no replacement is named.
OpenAI lists September 28, 2026 for removal of gpt-3.5-turbo-instruct, babbage-002, davinci-002 and gpt-3.5-turbo-1106, with gpt-5.6-terra as the replacement. The date has passed; current service availability has not been tested.
OpenAI lists October 1, 2026 for gpt-5.4-cyber API removal and now recommends the most capable cyber model available to the customer. GPT-5.6 Cyber independently requires separate approval and provisioning; it is no longer specifically named by this deprecation table.
Google’s current deprecation table lists March 15, 2027 as the earliest possible shutdown date for gemini-2.5-flash-image and recommends gemini-3.1-flash-lite-image. The previously displayed October 2 date and replacement-conflict description are historical.
Google schedules the May Antigravity preview for October 5 retirement and names antigravity-preview-09-2026 as successor. Remote output-only clients need an ID change; local tools and parsed function_call steps also change.
OpenAI lists October 5, 2026 as the billing start for gpt-rosalind-research. Standard rates are $5 input, $0.50 cached input and $25 output per million tokens in USD. Access remains limited to approved internal life-sciences research.
OpenAI schedules existing evals to become read-only on October 31, 2026, followed by shutdown of the Evals dashboard and API on November 30. Graders documented for eval workflows are part of the transition; fine-tuning follows a separate timeline.
OpenAI schedules API removal of gpt-5.3-codex, gpt-5.1 and gpt-5.4-nano for April 1, 2027. Its table recommends GPT-6 Sol for Codex and GPT-5.1, and GPT-6 Luna for Nano.
OpenAI schedules four exact text-to-speech model IDs for API removal on January 6, 2027 and recommends gpt-realtime-2.1-mini. The replacement model card lists Realtime support, so an existing speech-generation client needs an interface review.
Anthropic’s Sonnet 5.5 migration guidance changes thinking configuration, rejects forced tool choice and applies model, prefix and account conditions to thinking history. Legacy computer-tool and advisor restrictions have their own scopes; inter-tool text also changes response shape.
Anthropic’s September 30 notice schedules Claude API retirement of claude-sonnet-4-5-20250929 for November 30, 2026 and recommends claude-sonnet-5-5. Its status table labels the date tentative. Partner-operated platforms set separate schedules.
Fable 5.1 and Mythos 5.1 reject forced tool choice. Thinking replay depends on the target model. Fable’s prefix-history check also depends on account age, request settings and API surface; Mythos does not run that check.
Adopting gpt-6-astra requires a supported reasoning effort and removal of unsupported sampling/log-probability options. Chat Completions can serve requests without tools; Astra tool integrations must use Responses and its input/output Item shapes.
Rapid traffic growth uses 429/slow_down; model overload uses 503/server_is_overloaded. Clients must inspect both status and code.
OpenAI documents configurable project-key expiration and maximum lifetimes on September 10, and new-key creation restrictions on September 15. Organization restrictions bound project settings. Existing keys are unaffected by creation controls; this is no guarantee against expiration or revocation.
OpenAI announced reusable-prompt deprecation on June 3, 2026. The documented November 30 shutdown covers reusable prompt objects and v1/prompts. Move managed prompt content into application-owned code before that date.
Messages API code moving from Haiku 4.5 to Haiku 5.5 needs request and response-handling changes. Manual thinking budgets and assistant prefill fail, adaptive thinking is the default, and token counts and conversation-history rules change.
Managed Agents cloud environments using limited networking now apply allowed_hosts to server-side web_search and web_fetch. A mismatched enabled-tool allowed_domains entry can also make session creation or an update fail with HTTP 400.
