Title: Unveiling GPT 4.5: Stealth Release and Performance Upgrade Explained

GPT 4.5 likely stealth released:

• Speculation about GPT 4.5 release
• Evidence from leaked screenshot and discussions on Twitter

GPT-4 showing improved performance after being unreliable for weeks:

• The user noticed significant improvement in GPT-4's performance and speed, indicating it was more capable.
• There were rumors about the release of GPT-4.5, but Sam Altman denied its legitimacy.

OpenAI may have released GPT 4.5 in September:

• Evidence includes a tweet asking about GPT version and a chat response mentioning GPT 4.5 Turbo
• OpenAI may be stealthily split testing the new version with a portion of users

OpenAI released GPT 4.5:

• Users are getting GPT 4.5 'turbo' instead of GPT 4 due to model behavior changes.
• OpenAI may not have enough compute to serve all user demands, leading to limitations on usage.

GPT 4.5 release limitations and behavior changes:

• Limitations of GPT 4.5 due to high computing demands and cost
• Behavior changes in GPT 3.5 and GPT 4 over time, impacting performance

OpenAI likely stealth updated GPT 4 and GPT 3.5 without official announcements.:

• Evidence from March 2023 to June 2023 shows significant changes in GPT 4's abilities.
• Research paper confirms drastic drop in GPT 4's accuracy, indicating a major downgrade in its services.

GPT 4.5 release status is uncertain.:

• Futurist Flower suggests GPT 4 Turbo runs at low temperature, explaining mass hallucination.
• OpenAI may have conducted secret pre-release A/B testing similar to GPT 4 Turbo.

OpenAI has potentially released GPT 4.5 with subtle updates and split testing.:

• Users can test by asking GPT a question and observing the response for possible insights into the new system/API being used.
• Access to GPT 4.5 is a stealth release, with no setting to activate it, so users have to wait and hope to be part of the stealth update.
