OpenAI has launched GPT-5.3 Instant, enhancing ChatGPT interactions, while Google introduces Gemini 3.1 Flash-Lite, focused on speed and cost efficiency.
OpenAI has introduced the GPT-5.3 Instant model within ChatGPT, significantly improving the quality of interactions by enhancing the tone, relevance, and fluidity of conversations. This update aims to make user interactions with the chatbot more natural and effective, according to the developers.
The previous GPT-5.2 Instant model was noted for its sometimes overly cautious responses to sensitive topics. The new version reduces moralizing preambles, resulting in a more straightforward communication style.
When retrieving information from the internet, GPT-5.3 Instant provides more coherent and structured answers, recognizing the nuances of user queries and aligning the responses with its knowledge base. It avoids unnecessary phrases and is less likely to generate inaccurate information, although OpenAI warns that some responses in certain languages may be too literal.
Currently, GPT-5.3 Instant is accessible to all ChatGPT users and developers via API, with support for the older GPT-5.2 Instant model continuing until June 3, 2026.
OpenAI's GitHub Alternative
In addition to the new model, reports indicate that OpenAI is working on a GitHub alternative, although the project remains in its early stages. This new service is expected to be subscription-based, but specific details have yet to be released.
The initiative may stem from frustrations with GitHub's frequent outages, which have affected OpenAI engineers. If successful, this platform would compete directly with Microsoft, the owner of GitHub, which is also a significant investor in OpenAI.
Earlier this year, OpenAI raised $110 billion in funding, achieving a valuation of $730 billion, marking one of the largest funding rounds in startup history.
Google's Gemini Update
Meanwhile, Google has unveiled a preview of its Gemini 3.1 Flash-Lite model, described as the fastest and most cost-effective in the Gemini 3 lineup. The pricing structure includes $0.25 per million input tokens and $1.50 per million output tokens.
This model is optimized for tasks such as creating AI agents, large data translations, content moderation, and user interface generation. Independent research indicates that Gemini 3.1 Flash-Lite processes information 2.5 times faster than its predecessor, Gemini Flash 2.5.
Developers can access the new model through the Gemini API and Google AI Studio, while businesses can utilize it via Vertex AI. This follows Google's earlier introduction of the Gemini 3.1 Pro model, which set new records in performance benchmarks.
