官方要点
- This update focuses on the parts of the ChatGPT experience people feel every day: tone, relevance, and conversational flow. These are nuanced problems that don’t always show up in benchmarks, but shape whether ChatGPT feels helpful or frustrating. GPT‑5.3 Instant directly reflects user feedback in these areas. [...] We’re rolling out a new speech-to-text model for dictation in ChatGPT across all plans. This is a behind-the-scenes update, so there are no changes to how you use dictation. The update improves transcription accuracy across languages and accents, including when multilingual speakers mix or switch between languages. Evaluations showed gains in Japanese, Korean, Chinese, Urdu, Vietnamese, accented English, and long-form Spanish, French, Italian, and Portuguese. [...] We’re making an update to ChatGPT Voice that improves its ability to follow user instructions, and usage of tools like web search to provide better responses. This update applies to the version of Voice primarily used by those on the free ChatGPT plan, and by Plus users when limits are reached for the main model. # February 10, 2026 ## Updates to deep research
