Add a single cache_control field to your request body and the system automatically caches the last cacheable block, moving the cache point forward as conversations grow. No manual breakpoint management required. Works alongside existing block-level cache control for fine-grained optimization. Available on the Claude API and Microsoft Foundry (preview). Learn more in Prompt caching. We've retired the Claude Sonnet 3.7 model (claude-3-7-sonnet-20250219) and the Claude Haiku 3.5 model (claude-3-5-haiku-20241022). We announced the deprecation of the Claude Haiku 3 model (claude-3-haiku-20240307), with retirement scheduled for April 20, 2026.

Released Gemini 3.1 Pro Preview, our latest iteration in the new Gemini 3 series family. Launched a separate endpoint gemini-3.1-pro-preview-customtools, which is better at prioritizing custom tools, for users building with a mix of bash and tools.
Google · Gemini app·Feb 19, 2026
What: Building on the Gemini 3 series, we’re releasing 3.1 Pro, a smarter and more capable model for complex problem-solving. 3.1 Pro is designed for tasks where a simple answer isn’t enough, taking advanced reasoning and making it useful for your hardest challenges. This improved intelligence can help in practical applications — whether you’re looking for a clear, visual explanation of a complex topic, a way to synthesize data into a single view, or a step-by-step plan bringing an ambitious creative project to life. 3.1 Pro is rolling out globally to the Gemini app, with higher limits for users with Google AI Pro and Ultra plans. To access, select “Pro” in the model drop down. Why: We want to make Gemini the most helpful AI assistant for everyone. With the advanced reasoning of Gemini 3.1 Pro, you can now tackle your most complex projects with greater confidence.

Support for GPT-5.3-Codex-Spark. Added floating pop-out window to take a conversation with you. Improved performance and bug fixes. Alpha testing for the Codex app on Windows is also starting. Sign up here to be a potential alpha tester.
OpenAI · New model·Feb 12, 2026Announcement
Today, we're releasing a research preview of GPT-5.3-Codex-Spark, a smaller version of GPT-5.3-Codex and our first model designed for real-time coding. Codex-Spark is optimized to feel near-instant, delivering more than 1000 tokens per second while remaining highly capable for real-world coding tasks. Codex-Spark is available in research preview for ChatGPT Pro users in the latest Codex app, CLI, and IDE extension. This release also marks the first milestone in our partnership with Cerebras. At launch, Codex-Spark is text-only with a 128k context window. During the research preview, usage has separate model-specific limits and doesn't count against standard Codex limits. During high demand, access may slow down or queue while we balance reliability across users. To switch to GPT-5.3-Codex-Spark: In the CLI, start a new thread with: bash codex --model gpt-5.3-codex-spark Or use /model during a session. In the IDE extension, choose GPT-5.3-Codex-Spark from the model selector in the composer. In the Codex app, choose GPT-5.3-Codex-Spark from the model selector in the composer. If you don't see GPT-5.3-Codex-Spark yet, update the CLI, IDE extension, or Codex app to the latest version. GPT-5.3-Codex-Spark isn't available in the API at launch. For API-key workflows, continue using gpt-5.2-codex.
