Hey Devs! During this week, several important AI announcements were made that directly affect developers. Let’s jump into it. ;)

<h3>GPT-5.5 released to ChatGPT and Codex</h3>
OpenAI released GPT-5.5 to ChatGPT Pro and Codex users on 23 April 2026. The GPT-5.5 keeps the 1 M-token context window of GPT-5.4 but is priced at $5 per 1 M input tokens and $30 per 1 M output tokens, roughly double the price of GPT-5.4. Despite the price, GPT-5.5 improves performance on 9 of 10 benchmarks (e.g., ARC-AGI-2, MCP Atlas, Terminal-Bench 2.0) and completes the same Codex tasks with fewer tokens and similar per-token latency.

<h3>ChatGPT Images 2.0</h3>
OpenAI released ChatGPT Images 2.0, describing it as a complete rethink of its image‑generation model. The new model expands the product from a fun, creative tool into a visual workflow platform. PetaPixel notes that OpenAI designed Images 2.0 to be available across ChatGPT, Codex, and the API so that developers can incorporate it into code‑generation and research workflows

<h3>Google AI Agent Clinic lessons</h3>
Google’s AI Agent Clinic series published a post on 21 April 2026 that shares lessons from refactoring a monolithic sales‑research agent. The article is written for developers building complex agents and recommends:
<ul>
<li>Break up monolithic agents</li>
<li>Force structured outputs</li>
<li>Use dynamic Retrieval‑Augmented Generation (RAG)</li>
<li>Add observability and cost control</li>
</ul>
These lessons help developers design more maintainable and cost‑efficient AI agents that can survive in production.
