On Monday, OpenAI released a new foundation model called GPT-5.5 Instant, which will replace GPT-5.3 Instant as the default ChatGPT model. The company said the model reduces hallucination in sensitive areas such as law, medicine, and finance, while maintaining the low latency of its predecessor.

OpenAI released the latest GPT-5.5 model last month with the company claiming improvements in areas like coding and knowledge work.

The new model also achieved a score of 81.2 in the AIME 2025 math test, compared to 65.4 for the older model. It also outperformed its predecessor on the MMMU-Pro multimodal reasoning benchmark, with a score of 76.0 vs 69.2.

The release placed a particular emphasis on context management. GPT-5.5 Instant can use its search tool to refer back to past conversations, files, and Gmail to give you more personalized answers. This feature will be available to Plus and Pro users on the web, with plans to roll it out to mobile soon. OpenAI said that it plans to extend access to this feature to Free, Go Business, and enterprise users in the coming weeks.

With this update, ChatGPT will salso how memory sources across all models to help you understand where it generated the answers from. Users can delete outdated sources or correct them if the answer was wrong. Crucially, the company said that if you share a chat with someone, they won’t be able to see the memory sources.

For developers, the GPT-5.5 model will be available through API as ‘chat-latest,’ with 5.3 available as an option for paid users for only three months.

The company has faced rebuttal from previous model withdrawal moves. When OpenAI withdrew its GPT-4o model, there was significant backlash from users who related to the model’s “personality.” GPT-4o affirmed users’ choices frequently and that made them feel a connection to that particular model. Users who signed petitions to stop OpenAI from retiring it described the model as their “best friend” or “a mirror.” Despite the outcry, GPT-4o was deprecated in February 2026.

Nigerian attacker John Lawani has wasted no time making his mark in East Timor, enjoying an impressive start to life with Emmanuel FC following his move from Sri Lankan side ST Mary’s.

Sports247 reports that the promising forward has quickly announced himself in the Liga Futebol Amadora Primeira Divisão, scoring two goals in his opening two appearances for Emmanuel FC.

His early displays have showcased his attacking instincts, composure in front of goal, and ability to adapt seamlessly to a new environment.

Lawani’s bright start is a continuation of the fine form he displayed during his spell in Sri Lanka. Representing ST Mary’s in the Championship Division II, the Nigerian emerged as one of the team’s standout performers, scoring nine goals in just 12 appearances.

His contributions proved instrumental in ST Mary’s successful promotion campaign, helping the club secure a place in the Sri Lanka Super League, the nation’s top-flight competition.

The impressive goal return also underlined his reputation as a reliable finisher capable of delivering in crucial moments.

Seeking a fresh challenge, Lawani opted for a move to Emmanuel FC, where he has already begun to repay the club’s faith with goals and energetic performances.

His seamless transition to football in East Timor has provided encouragement for both the coaching staff and supporters, who will be hoping his scoring touch continues throughout the campaign.

At just the beginning of his journey with Emmanuel FC, the Nigerian forward appears well positioned to become a key figure in the club’s attacking setup.

His pace, movement, and eye for goal have already made him a difficult opponent for defenders, while his confidence in front of goal has been evident in his opening matches.

For Nigerian football fans, Lawani’s early success abroad is another example of homegrown talent making an impact on the international stage.

His performances in both Sri Lanka and now East Timor reflect a player steadily building a reputation for consistency and productivity in front of goal.

If his current form is any indication, Emmanuel FC could have secured one of the league’s most exciting attacking talents, with John Lawani poised to play a significant role in the club’s ambitions for the remainder of the season.
