1 Million Tokens: Breakthrough or Marketing Stunt? The GPT-5.4 Technical Deep Dive

In this episode of Neural Intel, we go beyond the hype of OpenAI’s March 5, 2026, release of GPT-5.4. While the 1,050,000 context window sounds like a game-changer, early user reports and needle-in-the-haystack evals suggest a significant accuracy drop-off after 256k tokens.In this deep dive, we discuss:The 1M Context Paradox: Why users are seeing "exponential" hallucination rates despite the massive window.Native Computer Use: How the new agents interact with OS environments and websites via visual input.Pro vs. Plus: The tiered rollout of GPT-5.4 Thinking and GPT-5.4 Pro.The Cost of Reasoning: Analyzing the new $2.50/M input token pricing and the efficiency of the unified Codex line.Join the conversation: 🌐 Website: neuralintel.org 🐦 X/Twitter: @neuralintelorg
