GPT-5's big new feature: less lying?

What It Covers

OpenAI announces GPT-5 with reduced hallucination rates and unified model interface, releases first open-weight model GPT-OSS in six years, while UK implements broad age verification requirements affecting Reddit, BlueSky, and major social platforms.

Key Questions Answered

• •GPT-5 Model Improvements: OpenAI eliminates the confusing model picker interface, routing requests automatically between reasoning and standard models. Users can now prompt "think harder" to access deeper reasoning capabilities, with hallucination rates dropping to 50% on deception benchmarks, though presentation charts contained misleading visualizations.
• •Open-Weight Model Strategy: GPT-OSS represents OpenAI's first open-weight release in six years under Apache 2.0 license, allowing local device deployment and custom training. This shift follows DeepSeek's competitive pressure and Chinese dominance in open-source AI leaderboards, enabling companies to run models behind firewalls without sending data to OpenAI servers.
• •UK Age Verification Rollout: UK's Online Safety Act now requires age verification for harmful content, blocking access to subreddits like r/periods and r/stopsmoking for unverified users. Implementation uses third-party services requiring government ID uploads, facial recognition scans, or credit card verification, creating unprecedented privacy concerns and blocking small websites unable to comply.
• •Apple AI Acquisition Pressure: Tim Cook publicly signals openness to major AI acquisitions for the first time in Apple history, responding to investor pressure about Safari search threats and talent losses to OpenAI and Meta. Apple faces potential disruption as voice-based OS interfaces could reduce iPhones to "dumb panes of glass" without competitive AI capabilities.
• •Tariff Impact on Tech Pricing: Nintendo raises Switch hardware prices by $30, Fujifilm increases camera prices by $800, and Apple reports $1 billion quarterly tariff costs. Trump announces 100% semiconductor tariffs with exemptions for US manufacturing commitments, creating selective enforcement based on company relationships and manufacturing pledges rather than consistent policy.
