{"collection":{"slug":"frontier-ai-labs","name":"Frontier AI Labs"},"digest":{"id":"cwd_8GcAIRarD9LU0pay2SNSC","weekStart":"2026-07-27","title":"Price cuts, Fast mode, and the end of GPT-5.4 in Codex","intro":"OpenAI slashed GPT-5.6 Luna pricing by 80%, added Fast mode to the Sol API, and set an August 31 retirement date for GPT-5.4 models in Codex, while the SDKs gained new fast tier and content provenance support.","body":"### Dramatic pricing shifts and a faster Sol\n\nThe week's biggest story came from [OpenAI's price cuts and Fast mode launch](/release/rel_NwmNscM1zn2am4nyV9d08-openai-cuts-gpt-5-6-luna-price-by-80-adds-fast-mode-to-sol-api): GPT-5.6 Luna dropped 80% in price and GPT-5.6 Terra fell 20%, reflecting efficiency improvements the company previewed earlier. At the same time, the GPT-5.6 Sol API gained Fast mode, delivering up to 2.5× faster speeds at twice the price, replacing the Priority Processing system with backward compatibility. The SDKs followed quickly — [Python SDK v2.51.0](/release/rel_DItcLN24Awuph3oT-Am3e-openai-python-sdk-v2-51-0-adds-fast-tier-to-api), [Node SDK v7.2.0](/release/rel_w_pBXuzI6bgxj4gaWvk9o-openai-node-sdk-v7-2-0-introduces-fast-tier), and [Go SDK v3.48.0](/release/rel_v-XnL9hlVvqDgKskITq0T-openai-go-sdk-v3-48-0-adds-fast-tier-to-api) all added support for the fast tier.\n\n### Codex model retirements and the sign-in bet\n\n[Codex is retiring GPT-5.4 and GPT-5.4 mini](/release/rel_WAVmxmc3t1fon0We5hn4u-codex-retires-gpt-5-4-and-gpt-5-4-mini-for-chatgpt-signed-in-users-on-august-31) for ChatGPT-signed-in users on August 31, with recommended replacements of GPT-5.6 Terra and GPT-5.6 Luna. The models remain available via the API and API-key-authenticated Codex sessions, but users need to update workspace defaults before the cutoff. Meanwhile, [Sign in with ChatGPT](/release/rel_n9JKBzl9q1gky3W5dOvJk-chatgpt-rolls-out-sign-in-with-chatgpt-beta-for-partner-plugins) launched in beta across select plugins and partner sites including Airtable, GitLab, HubSpot, Notion, Supabase, and Vercel — sharing only name, email, and profile picture. The [Codex team rolled out the same feature](/release/rel_lIkYzc8KY0sPZmGL1pbY1-codex-launches-sign-in-with-chatgpt-beta) for plugin connections, paired with a substantial [Codex update adding multi-repository review, image editing, and browser history search](/release/rel_JIFMhAYlYKkXiCTpJhdeP-codex-adds-multi-repository-review-image-editing-and-browser-history-search). The [Codex CLI 0.146.0](/release/rel_WmmYoKpgoStPupEYpmqeH-codex-cli-0-146-0-adds-session-naming-thread-forking-and-plugin-marketplace) also shipped session naming, thread forking, and Agent Plugins marketplace support for Amazon Bedrock and Claude Code.\n\n### SDK maintenance: version bumps and provenance\n\nThe SDK teams pushed two major version floor updates. [Python SDK v2.49.0](/release/rel_oYdnmwwXgIAJsYJgt7Nn6-openai-python-sdk-v2-49-0-requires-python-3-10) now requires Python 3.10 (up from 3.8), and [Node SDK v7.0.0](/release/rel_h8uCPF525Myk98P5i4jGl-openai-node-sdk-v7-0-0-requires-node-js-22) requires Node.js 22 with a codified version support policy. Later in the week, [Python SDK v2.52.0](/release/rel_bkLfKdAIBRXuj-G4jXqUo-openai-python-sdk-v2-52-0-adds-content-provenance-checks-and-honors-retry-after), [Node SDK v7.3.0](/release/rel_wBIjNV3tDfzeg8Xgzbmu8-openai-node-sdk-v7-3-0-adds-content-provenance-checks), and [Go SDK v3.49.0](/release/rel__ymtGH0EyJ3YwxpK9sfL5-openai-go-sdk-v3-49-0-adds-content-provenance-checks) all added content provenance checks — a new API feature for verifying the authenticity and origin of AI-generated content. The Python update also improved Retry-After handling up to two minutes.\n\n### Enterprise controls and academic workspaces\n\n[ChatGPT Enterprise & Edu](/release/rel_S0dgFgDQsEcGm2kMubW12-chatgpt-enterprise-edu-adds-per-environment-work-local-cloud-controls-and) gained per-environment Work Local/Cloud controls, Fast Mode defaults with custom-role overrides, and a redesigned Roles and Permissions page. Separately, [ChatGPT launched dedicated workspaces for academic researchers](/release/rel_kCa-ZTeLY6pVUsxF5Fwov-chatgpt-launches-dedicated-workspaces-for-academic-researchers-with-12-month) — faculty and postdoctoral researchers can apply for 12 months of free access for up to five verified team members, with business data protections and Pro-level usage limits.","releaseIds":["rel_NwmNscM1zn2am4nyV9d08","rel_DItcLN24Awuph3oT-Am3e","rel_w_pBXuzI6bgxj4gaWvk9o","rel_v-XnL9hlVvqDgKskITq0T","rel_WAVmxmc3t1fon0We5hn4u","rel_n9JKBzl9q1gky3W5dOvJk","rel_lIkYzc8KY0sPZmGL1pbY1","rel_JIFMhAYlYKkXiCTpJhdeP","rel_WmmYoKpgoStPupEYpmqeH","rel_oYdnmwwXgIAJsYJgt7Nn6","rel_h8uCPF525Myk98P5i4jGl","rel_bkLfKdAIBRXuj-G4jXqUo","rel_wBIjNV3tDfzeg8Xgzbmu8","rel__ymtGH0EyJ3YwxpK9sfL5","rel_S0dgFgDQsEcGm2kMubW12","rel_kCa-ZTeLY6pVUsxF5Fwov"],"releaseCount":20,"generatedAt":"2026-08-03T06:15:56.524Z","releases":[{"id":"rel_NwmNscM1zn2am4nyV9d08","title":"OpenAI cuts GPT-5.6 Luna price by 80%, adds Fast mode to Sol API","path":"/release/rel_NwmNscM1zn2am4nyV9d08-gpt-5-6-luna-80-cheaper-sol-api-gets-fast-mode","org":{"slug":"openai","name":"OpenAI"},"importance":5},{"id":"rel_DItcLN24Awuph3oT-Am3e","title":"OpenAI Python SDK v2.51.0 adds fast tier to API","path":"/release/rel_DItcLN24Awuph3oT-Am3e-fast-tier-added-to-api","org":{"slug":"openai","name":"OpenAI"},"importance":3},{"id":"rel_w_pBXuzI6bgxj4gaWvk9o","title":"OpenAI Node SDK v7.2.0 introduces fast tier","path":"/release/rel_w_pBXuzI6bgxj4gaWvk9o-fast-tier-added-to-api","org":{"slug":"openai","name":"OpenAI"},"importance":3},{"id":"rel_v-XnL9hlVvqDgKskITq0T","title":"OpenAI Go SDK v3.48.0 adds fast tier to API","path":"/release/rel_v-XnL9hlVvqDgKskITq0T-api-fast-tier-launched","org":{"slug":"openai","name":"OpenAI"},"importance":3},{"id":"rel_WAVmxmc3t1fon0We5hn4u","title":"Codex retires GPT-5.4 and GPT-5.4 mini for ChatGPT-signed-in users on August 31","path":"/release/rel_WAVmxmc3t1fon0We5hn4u-gpt-5-4-and-gpt-5-4-mini-retire-august-31","org":{"slug":"openai","name":"OpenAI"},"importance":4},{"id":"rel_n9JKBzl9q1gky3W5dOvJk","title":"ChatGPT rolls out Sign in with ChatGPT beta for partner plugins","path":"/release/rel_n9JKBzl9q1gky3W5dOvJk-sign-in-with-chatgpt-beta-lands-on-airtable-notion-vercel-and-more","org":{"slug":"openai","name":"OpenAI"},"importance":4},{"id":"rel_lIkYzc8KY0sPZmGL1pbY1","title":"Codex launches Sign in with ChatGPT beta","path":"/release/rel_lIkYzc8KY0sPZmGL1pbY1-sign-in-with-chatgpt-beta-rolls-out-across-plugins-and-partner-sites","org":{"slug":"openai","name":"OpenAI"},"importance":4},{"id":"rel_JIFMhAYlYKkXiCTpJhdeP","title":"Codex adds multi-repository review, image editing, and browser history search","path":"/release/rel_JIFMhAYlYKkXiCTpJhdeP-multi-repository-review-image-editing-browser-history-search","org":{"slug":"openai","name":"OpenAI"},"importance":3},{"id":"rel_WmmYoKpgoStPupEYpmqeH","title":"Codex CLI 0.146.0 adds session naming, thread forking, and plugin marketplace support","path":"/release/rel_WmmYoKpgoStPupEYpmqeH-sessions-named-and-pinned-threads-forked-plugin-support-expanded","org":{"slug":"openai","name":"OpenAI"},"importance":3},{"id":"rel_oYdnmwwXgIAJsYJgt7Nn6","title":"OpenAI Python SDK v2.49.0 requires Python 3.10","path":"/release/rel_oYdnmwwXgIAJsYJgt7Nn6-python-3-10-minimum-required","org":{"slug":"openai","name":"OpenAI"},"importance":3},{"id":"rel_h8uCPF525Myk98P5i4jGl","title":"OpenAI Node SDK v7.0.0 requires Node.js 22","path":"/release/rel_h8uCPF525Myk98P5i4jGl-node-js-22-required-version-support-codified","org":{"slug":"openai","name":"OpenAI"},"importance":4},{"id":"rel_bkLfKdAIBRXuj-G4jXqUo","title":"OpenAI Python SDK v2.52.0 adds content provenance checks and honors Retry-After up to 2 minutes","path":"/release/rel_bkLfKdAIBRXuj-G4jXqUo-content-provenance-checks-retry-after-delays-honored-up-to-2-minutes","org":{"slug":"openai","name":"OpenAI"},"importance":3},{"id":"rel_wBIjNV3tDfzeg8Xgzbmu8","title":"OpenAI Node SDK v7.3.0 adds content provenance checks","path":"/release/rel_wBIjNV3tDfzeg8Xgzbmu8-content-provenance-checks-land-in-the-api","org":{"slug":"openai","name":"OpenAI"},"importance":3},{"id":"rel__ymtGH0EyJ3YwxpK9sfL5","title":"OpenAI Go SDK v3.49.0 adds content provenance checks","path":"/release/rel__ymtGH0EyJ3YwxpK9sfL5-content-provenance-checks-added-to-api","org":{"slug":"openai","name":"OpenAI"},"importance":2},{"id":"rel_S0dgFgDQsEcGm2kMubW12","title":"ChatGPT Enterprise & Edu adds per-environment Work Local/Cloud controls and redesigned RBAC","path":"/release/rel_S0dgFgDQsEcGm2kMubW12-work-local-and-cloud-has-independent-admin-controls","org":{"slug":"openai","name":"OpenAI"},"importance":3},{"id":"rel_kCa-ZTeLY6pVUsxF5Fwov","title":"ChatGPT launches dedicated workspaces for academic researchers with 12-month free access","path":"/release/rel_kCa-ZTeLY6pVUsxF5Fwov-academic-researchers-get-12-month-free-chatgpt-workspace","org":{"slug":"openai","name":"OpenAI"},"importance":3}]}}
