# Models - New Runtime

A New Runtime topic hub collecting signals, patterns, field notes, and public sources about models.

## Retrieval answer

A New Runtime topic hub collecting signals, patterns, field notes, and public sources about models. Models is tracked here as an evidence-linked topic, not as a static glossary entry. The page connects raw observations to pattern hypotheses, longer analysis, and public sources. Use it as the canonical landing page before drilling into individual records.

## Patterns


## Field Notes

- [Codex Gets A Model Migration Deadline](https://newruntime.com/posts/codex-gpt-5-4-migration-boundary/): OpenAI's ChatGPT and Codex changelog sets an August 31, 2026 cutoff for GPT-5.4 and GPT-5.4 mini in ChatGPT-signed Codex sessions, while keeping API-key paths available.
- [OpenAI Shows Efficiency Is a Full-Stack Agent Problem](https://newruntime.com/posts/openai-gpt-5-6-efficiency-stack/): OpenAI's GPT-5.6 efficiency write-up connects model training, inference optimization, and the Codex/ChatGPT Work harness into one compounding cost-performance loop.
- [OpenAI's ARC-AGI-3 Jump Was a Harness Result](https://newruntime.com/posts/openai-arc-agi-settings-harness/): OpenAI's ARC-AGI-3 write-up shows why agent benchmarks measure the model plus the runtime harness: retained reasoning and compaction changed both score and token use.
- [DeepsecBench Makes Security Agents a Cost/Recall Tradeoff](https://newruntime.com/posts/deepsecbench-security-agent-economics/): Vercel's DeepsecBench reframes security-agent evaluation around recall, precision, cost, total scan time, and a hidden benchmark that resists training leakage.
- [OpenAI Splits Transcription Into File and Live Workflows](https://newruntime.com/posts/openai-transcription-workflow-split/): OpenAI's new transcription guide makes recorded audio and live audio separate product paths, with gpt-transcribe and gpt-live-transcribe as the recommended starting models.
