https://mixtpatrik.github.io/killedbyai/ A digital cemetery for discontinued AI models, apps, startups, and hardware. en-us Wed, 10 Jun 2026 18:55:42 +0000 https://mixtpatrik.github.io/killedbyai/#openai-assistants-api-beta https://mixtpatrik.github.io/killedbyai/#openai-assistants-api-beta Wed, 26 Aug 2026 00:00:00 +0000 OpenAI's persistent 'assistants' framework that bundled model choice, instructions, file handling, and tool declarations into reusable API objects. Announced at DevDay 2023 alongside GPTs, it never left beta. Being sunset in favor of the newer Responses API, which moved prompt versioning into the dashboard. service https://mixtpatrik.github.io/killedbyai/#claude-sonnet-4-opus-4 https://mixtpatrik.github.io/killedbyai/#claude-sonnet-4-opus-4 Mon, 15 Jun 2026 00:00:00 +0000 Anthropic's flagship Claude 4 generation — Sonnet 4 and Opus 4 — retired less than a year after launch. API calls to claude-sonnet-4-0 and claude-opus-4-0 return errors after June 15, 2026. Replaced by the 4.5 and 4.7 series with dramatically improved coding and computer use capabilities. model https://mixtpatrik.github.io/killedbyai/#stainless-sdk-generator https://mixtpatrik.github.io/killedbyai/#stainless-sdk-generator Mon, 18 May 2026 00:00:00 +0000 The startup that auto-generated production-ready API SDKs in Python, TypeScript, Go, Java, and Kotlin. Used by OpenAI, Google, Cloudflare, Replicate, Runway, and Meta. Anthropic acquired it for $300M+ and immediately announced it would wind down all hosted products — a strategic kill to deny competitors access to critical infrastructure. startup https://mixtpatrik.github.io/killedbyai/#xai-grok-legacy-models https://mixtpatrik.github.io/killedbyai/#xai-grok-legacy-models Fri, 15 May 2026 00:00:00 +0000 Eight Grok models retired at once: grok-4-1-fast, grok-4-fast, grok-4-0709, grok-code-fast-1, grok-3, and grok-imagine-image-pro. xAI silently redirected all retired slugs to grok-4.3 — meaning developers' bills and output quality changed without code changes or warnings. A masterclass in how NOT to handle deprecation. model https://mixtpatrik.github.io/killedbyai/#dall-e-3-api-snapshots https://mixtpatrik.github.io/killedbyai/#dall-e-3-api-snapshots Tue, 12 May 2026 00:00:00 +0000 The specific dated snapshots of DALL·E 3 used via the Images API were scheduled for removal as OpenAI consolidated image generation under GPT-4o's native image capabilities. Another casualty of the 'everything in one model' consolidation trend. model https://mixtpatrik.github.io/killedbyai/#openai-realtime-api-beta https://mixtpatrik.github.io/killedbyai/#openai-realtime-api-beta Tue, 12 May 2026 00:00:00 +0000 OpenAI's WebSocket-based API for building real-time voice conversations, powering Advanced Voice Mode demos. The beta endpoint was deprecated as OpenAI shipped a GA (general availability) version with a different interface, forcing developers to rewrite their integrations. service https://mixtpatrik.github.io/killedbyai/#claude-3-7-sonnet https://mixtpatrik.github.io/killedbyai/#claude-3-7-sonnet Mon, 11 May 2026 00:00:00 +0000 Anthropic's first model with hybrid 'extended thinking' — it could reason step-by-step for up to 128K tokens before answering, scoring state-of-the-art on SWE-Bench coding benchmarks at launch. Deprecated just 15 months after release as the Claude 4 family made extended thinking standard across the entire lineup. model https://mixtpatrik.github.io/killedbyai/#gpt-5-2-gpt-5-3-api-snapshots https://mixtpatrik.github.io/killedbyai/#gpt-5-2-gpt-5-3-api-snapshots Fri, 08 May 2026 00:00:00 +0000 OpenAI deprecated the gpt-5.2-chat-latest and gpt-5.3-chat-latest snapshots less than 4 months after release. The pace of model churn has become so extreme that even 'latest' models are now deprecated quarterly, leaving developers in a permanent migration treadmill. model https://mixtpatrik.github.io/killedbyai/#google-project-mariner https://mixtpatrik.github.io/killedbyai/#google-project-mariner Mon, 04 May 2026 00:00:00 +0000 Google DeepMind's experimental AI browser agent that could navigate Chrome, fill out forms, book travel, and complete web tasks by taking screenshots and clicking for you. Quietly killed after 17 months when staff were reassigned. The tech was absorbed into Gemini Agent. Privacy concerns and high compute costs for visual processing made it unsustainable. service https://mixtpatrik.github.io/killedbyai/#google-doppl https://mixtpatrik.github.io/killedbyai/#google-doppl Thu, 30 Apr 2026 00:00:00 +0000 Google Labs' AI-powered virtual try-on app that let users see how clothes would look on their avatar.

The free OAuth tier was killed 48 hours after MiniMax made the same move, as Chinese AI labs pivot from 'free for growth' to subscription economics. Daily free requests slashed from 1,000 to 100. service https://mixtpatrik.github.io/killedbyai/#minimax-api-free-tier https://mixtpatrik.github.io/killedbyai/#minimax-api-free-tier Mon, 13 Apr 2026 00:00:00 +0000 Chinese AI lab MiniMax was one of the most generous in offering free API access to developers. Killed its free tier two days before Alibaba's Qwen did the same — signaling the end of the 'free forever' era of Chinese AI APIs as labs pivot from land-grab growth to sustainable economics. service https://mixtpatrik.github.io/killedbyai/#google-interview-warmup https://mixtpatrik.github.io/killedbyai/#google-interview-warmup Wed, 01 Apr 2026 00:00:00 +0000 Google's free AI-powered interview practice tool that helped millions of job seekers rehearse common interview questions with real-time transcription and ML-based analysis. Quietly killed in April 2026 with no announcement — visitors clicking 'Get Started' are silently redirected to a generic 'How to Prepare for an Interview' article. service https://mixtpatrik.github.io/killedbyai/#gpt-4o-api-2024-05-13-2024-08-06 https://mixtpatrik.github.io/killedbyai/#gpt-4o-api-2024-05-13-2024-08-06 Tue, 31 Mar 2026 00:00:00 +0000 The original GPT-4o API snapshots were auto-upgraded to GPT-5.1 when they retired. Developers who relied on specific model behavior, fine-tuning, or output consistency were forced into a blind migration with no rollback option. model https://mixtpatrik.github.io/killedbyai/#gpt-4o-realtime-preview https://mixtpatrik.github.io/killedbyai/#gpt-4o-realtime-preview Thu, 26 Mar 2026 00:00:00 +0000 OpenAI's low-latency speech-to-speech API that powered the viral 'Advanced Voice Mode' demos. The preview endpoint was sunset as OpenAI transitioned to newer realtime models, leaving apps that built voice experiences on top of it with a hard migration deadline. model https://mixtpatrik.github.io/killedbyai/#google-gemini-3-pro-preview https://mixtpatrik.github.io/killedbyai/#google-gemini-3-pro-preview Mon, 09 Mar 2026 00:00:00 +0000 Google's flagship Gemini 3 preview release. Lived just 111 days before being replaced by Gemini 3.1 Pro Preview — one of the shortest-lived frontier model releases, highlighting how 'preview' is now shorthand for 'expect to migrate in three months.' model https://mixtpatrik.github.io/killedbyai/#adobe-animate https://mixtpatrik.github.io/killedbyai/#adobe-animate Sun, 01 Mar 2026 00:00:00 +0000 Originally Macromedia Flash, then Adobe Flash Professional, then Adobe Animate. After 30 years, Adobe announced it would kill the app to refocus on AI tools. Intense backlash forced a reversal — Adobe put it on 'maintenance mode' instead, but no new features will be developed. app https://mixtpatrik.github.io/killedbyai/#google-assistant-on-mobile https://mixtpatrik.github.io/killedbyai/#google-assistant-on-mobile Sun, 01 Mar 2026 00:00:00 +0000 Google's final shutdown date for the classic Google Assistant on Android phones and tablets. After years of deprioritization, Gemini fully replaced it on mobile — ending a decade-long voice assistant that once powered hundreds of millions of devices across phones, speakers, and displays. app https://mixtpatrik.github.io/killedbyai/#cydoc https://mixtpatrik.github.io/killedbyai/#cydoc Sat, 21 Feb 2026 00:00:00 +0000 A bootstrapped health AI startup that operated for 7 years trying to build clinical AI tools.

Scans stopped January 15, 2026, and all monitoring data was wiped February 16. Google said user feedback showed the tool failed to provide useful follow-up steps after flagging breaches. service https://mixtpatrik.github.io/killedbyai/#gpt-4o-chatgpt https://mixtpatrik.github.io/killedbyai/#gpt-4o-chatgpt Fri, 13 Feb 2026 00:00:00 +0000 OpenAI's 'omni' multimodal model that processed text, audio, image, and video. Despite becoming the most-used AI model globally, it was retired from ChatGPT after GPT-5 captured nearly all usage. The retirement sparked emotional backlash from ~800K daily users who had formed attachments to the model's personality. model https://mixtpatrik.github.io/killedbyai/#gpt-4o-api-snapshots https://mixtpatrik.github.io/killedbyai/#gpt-4o-api-snapshots Fri, 13 Feb 2026 00:00:00 +0000 Alongside its ChatGPT retirement, the legacy GPT-4o API snapshots were sunset for developers. GPT-4.1, GPT-4.1 mini, and o4-mini were retired in the same wave. After powering billions of conversations, 4o became the most-mourned model in AI history with users petitioning for its return. model https://mixtpatrik.github.io/killedbyai/#kintsugi-ai https://mixtpatrik.github.io/killedbyai/#kintsugi-ai Wed, 11 Feb 2026 00:00:00 +0000 An AI startup that spent 7 years and $30M developing voice biomarker technology to detect depression and anxiety from how people speak. Shut down after nearly 4 years waiting for FDA De Novo clearance that never came.
