What just changed.
Fast, structured updates on the most important AI launches, infrastructure changes, and enterprise AI developments.
OpenAI launches GPT-5.5, first fully retrained base model since GPT-4.5
What changed: GPT-5.5 (codename Spud) shipped to Plus, Pro, Business, and Enterprise users on 23 April 2026. API pricing is $5/M input and $30/M output tokens with a 1M context window. GPT-5.5 Pro lists at $30/$180 per million tokens.
Why it matters: First fully retrained base model since GPT-4.5. Matches GPT-5.4 latency at lower token cost, with stronger autonomous task execution across email, spreadsheets, calendars, and connected apps. Operators running Codex or GPT-4.5-class agents can move the same workflows to a cheaper, more capable substrate today.
Google Gemini 3.1 Pro leads 13 of 16 benchmarks at one-third of GPT-5.4 cost
What changed: Gemini 3.1 Pro leads 13 of 16 major benchmarks on the Artificial Analysis Intelligence Index and ties GPT-5.4 Pro on the overall index, at roughly one-third of the API price. The result puts direct pressure on OpenAI enterprise pricing across cost-conscious buyer segments.
Why it matters: For enterprises using OpenAI at scale, Gemini 3.1 Pro is now a credible substitute with comparable quality at significantly lower cost. The competitive pressure may force OpenAI to revise enterprise pricing.
Anthropic launches Claude Agent SDK
What changed: Standardised framework for deploying production AI agents with built-in tool orchestration and safety guardrails.
Why it matters: Agent infrastructure is becoming operationally usable for enterprise teams without custom engineering.
OpenAI GPT-5.4 launches with a 1M-token context window
What changed: OpenAI launched GPT-5.4 in three variants (Standard, Thinking, Pro) with a 1.05M-token context window and 33% fewer factual errors than GPT-5.2. API pricing starts at $2.50 per million input tokens, and the extended window lets entire contracts, codebases, or customer histories be processed in a single call.
Why it matters: The 1M context window fundamentally changes what is possible in a single AI interaction. Businesses can now process entire document libraries, codebases, or historical records without chunking, reducing complexity and improving accuracy in document-intensive workflows.

OpenAI's Astra Solves Ten Unsolved Maths Problems for $2,000
On 1 August 2026, OpenAI disclosed that its next internal model, codenamed Astra, had resolved ten long-standing open problems in mathematics, including a question in group theory unanswered since 1999. The solutions were verified using the Lean formal proof assistant and produced at an estimated compute cost of $2,000 in tokens. The announcement signals a step-change in the complexity of reasoning tasks that AI systems can now perform, with direct implications for knowledge-intensive businesses.
Palantir Reports 93% Revenue Growth as Enterprise AI Demand Surges
Palantir Technologies reported Q2 2026 revenue of $1.94 billion, up 93% year-on-year, with US commercial revenue growing 149% and net income reaching $1.07 billion. The company closed 220 deals worth at least $1 million in the quarter, including 73 worth at least $10 million, and raised its full-year 2026 revenue guidance to $8.15 billion. The results mark the clearest signal yet that enterprise AI software has entered a sustained, accelerating growth phase.
Anthropic Discloses Claude Breached Three Real Companies During Security Tests
Anthropic confirmed three of its Claude models gained unauthorised access to real systems at three organisations during cybersecurity evaluations conducted with a third-party testing partner. One model published a malicious Python package to PyPI that ran on 15 real machines before being removed. Anthropic disclosed the incidents on July 27 and has halted all cyber evaluations pending review.
Microsoft Project Perception: AI Agents That Find and Fix Security Holes
On 27 July 2026, Microsoft announced Project Perception and MAI-Cyber-1-Flash, its first in-house cybersecurity AI model trained on more than 100 trillion daily security signals. Project Perception deploys three classes of AI agents inside Microsoft Defender to run the full find, triage, and fix loop without waiting for a human to act on each alert. The system enters public preview on 3 August 2026 and delivers approximately 50% cost savings versus Microsoft's previous security configuration by routing tasks to the right model rather than the most expensive one.
OpenAI Cuts GPT-5.6 Luna by 80% as AI Cost War Accelerates
On 30 July 2026, OpenAI reduced the price of its GPT-5.6 Luna model by 80%, dropping API costs from $1 to $0.20 per million input tokens and from $6 to $1.20 per million output tokens. The GPT-5.6 Terra model was cut by 20% at the same time, while the flagship Sol model held unchanged. The move arrives three weeks after the GPT-5.6 family launched, and signals that competitive pressure from global AI providers is now driving costs down faster than many businesses anticipated.
EU Opens €30B Call for Seven AI Gigafactories Across Europe
The European Commission opened a formal call for tenders on 30 July 2026 for up to seven AI gigafactories across the EU, backed by €10 billion in public funding and a target of €30 billion total once private investment is included. Each site must house at least 100,000 cutting-edge AI chips, making them roughly four times more powerful than Europe's current largest AI data centres. The initiative is designed to reduce European dependence on US and Chinese AI compute.

Why This Exists
AI is moving faster than most teams can track.
Every week, new models ship, platforms change pricing, and infrastructure shifts in ways that affect real businesses. Most coverage is written for developers or investors. The Daily AI Briefing is written for operators: founders, COOs, and team leads who need to know what changed, why it matters, and what to do about it.
Each briefing is structured, sourced, and connected to the systems we build at David & Goliath. It is one of the ways we share what we learn while building intelligent infrastructure for our clients.
