AI Development Tools launch history

GPT-5.3 Codex is now available in Cursor! It's noticeably faster than 5.2 and is now the preferred model for many of our engineers.

Composer 1.5 is now available. We’ve found it to strike a strong balance between intelligence and speed. https://t.co/jK92KCL5ku

Opus 4.6 is now available in Cursor! It's highly effective at long-running tasks and reviewing code.

📣 @OpenAIDevs GPT-5.3-Codex is now generally available and rolling out in GitHub Copilot. Early testing shows ➡️ It reaches new high scores on benchmarks we use to evaluate coding, agentic, and real-world capabilities ➡️ 25% faster performance than GPT-5.2-Codex on agentic

Claude Sonnet 4.6 is now available to all Perplexity Pro and Max subscribers. https://t.co/fCq5w8gbho

Opus 4.6 (fast mode) is now available in Cursor! It's 2.5x as fast in research preview.

A few small updates today - we've added Moodboards and Personalization to Niji V7. We've released a much better web interface for Personalization. And we are sunsetting web rooms as we work on next-gen collab tools (which should make the whole site feel noticeably faster). Enjoy!

Gemini 3.1 Pro is now available to all Perplexity Pro and Max subscribers. https://t.co/Nk0N0FXWgM

New voice mode upgrades are rolling out today across Perplexity and Comet for all users. https://t.co/uY8R1yUo9P

Following the open-source release of Qwen3-Coder-Next, its API is now available on Alibaba Cloud Model Studio and has also been integrated into the Coding Plan. For teams and developers who prefer scalable or cost-effective endpoints, you can now access Qwen3-Coder-Next via API.

Voxtral Realtime is built for voice agents and live applications. Its natively streaming architecture delivers latency configurable to sub-200ms. And at 480ms, it stays within 1-2% WER of our offline model. We release the model as open weights under Apache 2.0. https://t.co/sZwzCDd4tu

Opus 4.6 is now available on Perplexity for Max subscribers. Try it in Model Council to compare it with other frontier models. https://t.co/SAyuUgqnzy

Perplexity APIs are now in hundreds of millions of Samsung devices and 6 of the Mag 7. And we just released an API for search embeddings that outperforms Google. Join us in San Francisco to see what’s next, hear from Perplexity founders, and connect with top devs.

This week we launched Perplexity Computer, the most powerful AI product yet. We are just warming up. Join us March 11 to see what’s next.
