Introducing SWE-1: Powering 99% Faster Software Development

Windsurf proudly unveils SWE-1, our first family of frontier models tailored for the entire software engineering lifecycle, not just coding. With three distinct models—SWE-1, SWE-1-lite, and SWE-1-mini—these releases redefine AI-driven development, offering powerful, cost-effective tools for teams worldwide.

The Details:

• SWE-1: Matches Claude 3.5 Sonnet-level reasoning at lower costs. Free for paid users (0 credits per prompt) during a promotional period.

• SWE-1-lite: Replaces Cascade Base with superior quality, available for unlimited use to all users, free or paid.

• SWE-1-mini: A fast, lightweight model powering the Windsurf Tab passive experience for all users.

• Purpose: Designed to accelerate software engineering by 99%, addressing coding, terminal tasks, user feedback, and long-term project evolution.

Developer Impact:
SWE-1 rivals leading AI models, delivering free and premium options for seamless team collaboration. Built on flow-aware systems, these models excel in human-in-the-loop workflows, handling incomplete states and complex tasks. While some Windsurf Editor betas face delays for UX polish, SWE-1’s benchmarks show near-frontier performance. Test thoroughly, as credit costs may apply for feedback. SWE-1 empowers innovative teams to build smarter, faster, and bigger.

OpenAI’s Codex: Supercharging Software Engineering

OpenAI introduces Codex, a cloud-based software engineering agent powered by codex-1, designed to handle multiple coding tasks in parallel. Available now for ChatGPT Pro, Team, and Enterprise users, with Plus and Edu access coming soon, Codex transforms development by automating features, bug fixes, and pull requests.

The Details:

• Codex Functionality: Performs tasks like writing features, answering codebase questions, fixing bugs, and proposing pull requests in isolated cloud sandboxes preloaded with your repository.

• Codex-1 Model: A specialized version of OpenAI’s o3, trained with reinforcement learning to mirror human coding styles and adhere to instructions, with strong performance on SWE-Bench and internal benchmarks.

• Access: Available via ChatGPT sidebar for Pro, Team, and Enterprise users; Plus and Edu support forthcoming. Codex CLI now includes codex-mini-latest for low-latency workflows.

• Safety & Transparency: Operates in secure, internet-free containers with verifiable outputs via terminal logs and test citations.

Developer Impact:
Codex rivals dedicated engineering tools, offering free access for eligible ChatGPT users during the initial rollout. Its flow-aware, multi-tasking capabilities enhance team productivity by offloading repetitive tasks like refactoring and testing.

While some features, like image inputs, are still in development, Codex’s asynchronous workflow and AGENTS.md guidance make it a versatile tool for modern codebases. Test thoroughly, as task completion times vary (1-30 minutes). Codex empowers innovative teams to ship faster and focus on high-impact work.

Report: Spring 2025 AI Model Usage Trends

Poe’s 2025 AI usage report unveils seismic shifts in how users harness frontier models, from reasoning powerhouses to cutting-edge multimedia tools. As the go-to platform for exploring over 100 AI models in one interface, Poe offers a front-row seat to the trends reshaping development and creativity.

The Details:

• Reasoning Models Surge: Usage of reasoning models grew from 2% to 10% of text messages, driven by DeepSeek’s viral moment and models like Gemini 2.5 Pro (~30% reasoning share) and OpenAI’s o3/o4 series.

• Text Model Shifts: OpenAI’s GPT-4.1 and Google’s Gemini 2.5 Pro gained ~10% and ~5% message shares, while Anthropic’s Claude family dropped ~10%. New models often cannibalize older ones.

• Image Generation Rivalries: Black Forest Labs’ FLUX (~35%) and Google’s Imagen3 (~30%) lead, but OpenAI’s GPT-Image-1 hit 17% in two weeks.

• Video Generation Dynamics: Kuaishou’s Kling family (~30%, led by Kling-2.0-Master at 21%) outpaces Runway (~20%) and Google’s Veo 2 (~20%).

• Audio Dominance: ElevenLabs holds ~80% of text-to-speech requests, though competitors like Cartesia and PlayAI are emerging.

Developer Impact:
Poe’s data reveals a dynamic AI landscape where developers leverage reasoning models for complex coding tasks and multimedia models for innovative interfaces. With access to over 100 models in one platform, devs can experiment with cutting-edge tools like Gemini 2.5 Pro and Kling 2.0, but rapid model shifts require staying agile. Test emerging models to optimize workflows, as usage trends favor the latest releases. Poe empowers developers to drive innovation in an evolving AI ecosystem.

📚 CURATED LEARNING RESOURCES

The Abundance Mindset: Learning to Thrive in the AI Coding Revolution

This ChatGPT Codex podcast featuring Josh Ma and Alexander Embiricos from the OpenAI team offers remarkably concrete insights about the vital importance of learning in the AI-assisted development era. Unlike abstract discussions about education, the conversation reveals specific technical advantages for those who continuously adapt, including how "you can run up to 60 concurrent Codex instances per hour" with an "abundance mindset" rather than crafting perfect prompts. The team shares practical learning approaches, emphasizing typed languages over untyped ones: "Python > Ruby, TS > JS."

Particularly valuable are the candid discussions about workflow transformation, with Alexander stating developers should "make your code modular" and use tools to "ask it what it should do" rather than feeling obligated to direct every aspect. The article even reveals how they're seeing productivity shifts toward high-value work: "we do the work that's like ambiguous or creative or hard to automate... and otherwise we just have agents that we're delegating most of the work to." These specific, quantifiable examples make clear that learning to effectively partner with AI isn't just beneficial—it's essential for staying relevant in a landscape where technological competence determines whether you thrive or fall behind.

The AI Ascent: Why Learning Is Non-Negotiable in the Agent Economy

The Sequoia AI event featuring Pat, Sonia, and Constantine delivers powerful insights about continuous learning's critical role in our AI-transformed future. They paint a striking picture of market acceleration—cost per token has plummeted 99% in under two years while technology adoption overwhelms market volatility. This isn't just another tech wave; it's fundamentally different in scale and speed.

The speakers articulate a clear framework for navigating this transition. Value concentrates at the application layer where businesses evolve from selling tools to delivering outcomes. We're witnessing the emergence of what Constantine describes as an agent economy—systems that transfer resources, execute transactions, and maintain trust relationships independent of constant human oversight.

Most compelling is their analysis of the necessary mindset evolution. We must shift from deterministic to stochastic thinking, embracing greater leverage alongside increased uncertainty. The rules of success are changing: companies now scale faster with fewer people, and management skills become paramount as we learn to guide AI systems rather than perform individual contributor roles.

For anyone looking to remain relevant, the message is unambiguous—adaptation isn't optional. Those who fail to develop new skills, embrace uncertainty, and learn to collaborate with intelligent systems risk being left behind in an economy being fundamentally rewired by AI. The future belongs to those who can harness this unprecedented leverage while developing the judgment to navigate its inherent unpredictability.
