What is GPT‑5.3‑Codex‑Spark?

GPT-5.3-Codex-Spark is a specialized, ultra-fast coding model designed to enable real-time collaboration within the Codex platform. As a streamlined variant of GPT-5.3-Codex, it prioritizes latency-sensitive workflows where immediate responsiveness is critical. When deployed on Cerebras’ Wafer Scale Engine 3 hardware, Codex-Spark delivers more than 1000 tokens per second, dramatically accelerating interactive development sessions. The model supports a 128k context window, allowing developers to maintain broad project awareness while iterating quickly. It is optimized for making minimal, precise edits and refining logic or interfaces without automatically executing additional steps unless instructed. OpenAI implemented extensive infrastructure upgrades—including persistent WebSocket connections and inference stack rewrites—to reduce time-to-first-token by 50% and cut client-server overhead by up to 80%. On software engineering benchmarks such as SWE-Bench Pro and Terminal-Bench 2.0, Codex-Spark demonstrates strong capability while completing tasks in a fraction of the time required by larger models. During the research preview, usage is governed by separate rate limits and may be queued during peak demand. Codex-Spark is available to ChatGPT Pro users through the Codex app, CLI, and VS Code extension, with API access for select design partners. The model incorporates the same safety and preparedness evaluations as OpenAI’s mainline systems. This release signals a shift toward dual-mode coding systems that combine rapid interactive loops with delegated long-running tasks. By tightening the iteration cycle between idea and execution, GPT-5.3-Codex-Spark expands what developers can build in real time.

What is Claude Opus 4.5?

Claude Opus 4.5 represents a major leap in Anthropic’s model development, delivering breakthrough performance across coding, research, mathematics, reasoning, and agentic tasks. The model consistently surpasses competitors on SWE-bench Verified, SWE-bench Multilingual, Aider Polyglot, BrowseComp-Plus, and other cutting-edge evaluations, demonstrating mastery across multiple programming languages and multi-turn, real-world workflows. Early users were struck by its ability to handle subtle trade-offs, interpret ambiguous instructions, and produce creative solutions—such as navigating airline booking rules by reasoning through policy loopholes. Alongside capability gains, Opus 4.5 is Anthropic’s safest and most robustly aligned model, showing industry-leading resistance to strong prompt-injection attacks and lower rates of concerning behavior. Developers benefit from major upgrades to the Claude API, including effort controls that balance speed versus capability, improved context efficiency, and longer-running agentic processes with richer memory. The platform also strengthens multi-agent coordination, enabling Opus 4.5 to manage subagents for complex, multi-step research and engineering tasks. Claude Code receives new enhancements like Plan Mode improvements, parallel local and remote sessions, and better GitHub research automation. Consumer apps gain better context handling, expanded Chrome integration, and broader access to Claude for Excel. Enterprise and premium users see increased usage limits and more flexible access to Opus-level performance. Altogether, Claude Opus 4.5 showcases what the next generation of AI can accomplish—faster work, deeper reasoning, safer operation, and richer support for modern development and productivity workflows.
