The router is continuously trained on real signals, including when users switch models, preference rates for responses, and measured correctness, improving over time. Once usage limits are reached, a mini version of each model handles remaining queries.\n  This system card focuses primarily on gpt-5-thinking and gpt-5-main, while evaluations for other models are available in the appendix. The GPT-5 system not only outperforms previous models on benchmarks and answers questions more quickly, but -- more importantly -- is more useful for real-world queries. We've made significant advances in reducing hallucinations, improving instruction following, and minimizing sycophancy, and have leveled up GPT-5's performance in three of ChatGPT's most common uses: writing, coding, and health. All of the GPT-5 models additionally feature safe-completions, our latest approach to safety training to prevent disallowed content.\n  Similarly to ChatGPT agent, we have decided to treat gpt-5-thinking as High capability in the Biological and Chemical domain under our Preparedness Framework, activating the associated safeguards. While we do not have definitive evidence that this model could meaningfully help a novice to create severe biological harm -- our defined threshold for High capability -- we have chosen to take a precautionary approach.","external_url":"https://arxiv.org/abs/2601.03267","cited_by_count":null,"metadata_source":"pith","metadata_fetched_at":"2026-06-29T10:23:17.988056+00:00","pith_arxiv_id":"2601.03267","created_at":"2026-05-09T04:30:10.963974+00:00","updated_at":"2026-06-29T10:23:17.988056+00:00","title_quality_ok":false,"display_title":"OpenAI GPT-5 System Card","render_title":"OpenAI GPT-5 System Card"},"hub":{"state":{"work_id":"ca87689a-0d29-4476-b504-b65dbbb08af4","tier":"super_hub","tier_reason":"100+ Pith inbound or 10,000+ external citations","pith_inbound_count":330,"external_cited_by_count":null,"distinct_field_count":21,"first_pith_cited_at":"2025-11-12T03:48:05+00:00","last_pith_cited_at":"2026-06-16T03:35:17+00:00","author_build_status":"needed","summary_status":"needed","contexts_status":"needed","graph_status":"needed","ask_index_status":"needed","reader_status":"not_needed","recognition_status":"not_needed","updated_at":"2026-06-29T10:18:34.783380+00:00","tier_text":"super_hub"},"tier":"super_hub","role_counts":[{"context_role":"background","n":43},{"context_role":"baseline","n":23},{"context_role":"method","n":7},{"context_role":"dataset","n":3},{"context_role":"other","n":3}],"polarity_counts":[{"context_polarity":"background","n":40},{"context_polarity":"baseline","n":23},{"context_polarity":"use_method","n":7},{"context_polarity":"unclear","n":5},{"context_polarity":"use_dataset","n":3},{"context_polarity":"support","n":1}],"runs":{"ask_index":{"job_type":"ask_index","status":"succeeded","result":{"title":"OpenAI GPT-5 System Card","claims":[{"claim_text":"This is the system card published alongside the OpenAI GPT-5 launch, August 2025.\n  GPT-5 is a unified system with a smart and fast model that answers most questions, a deeper reasoning model for harder problems, and a real-time router that quickly decides which model to use based on conversation type, complexity, tool needs, and explicit intent (for example, if you say 'think hard about this' in the prompt).
