🤖GPT-5.5 Goes Live as AI Labs Enter a Weekly Launch Cycle
The Rundown: OpenAI launched GPT-5.5 with advanced agentic capabilities just one week after Anthropic's Opus 4.7, while Anthropic quietly crossed a $1 trillion valuation — surpassing OpenAI itself.
The details:
- ●GPT-5.5 scores 82.7% on Terminal-Bench 2.0, is priced at $5/M input tokens, features a 1M token context window, and is live in ChatGPT and Codex now.
- ●OpenAI Workspace Agents automate Slack and team workflows for free until May 6, 2026 on Business, Enterprise, Edu, and Teachers plans.
- ●Anthropic surpassed OpenAI with a $1 trillion valuation on Forge Global, driven by Claude Code adoption and scarce available shares.
- ●DeepSeek V4-Pro launched with 1.6 trillion parameters and a 1M token context window, while DeepSeek is in talks to raise at a $20B valuation backed by Tencent and Alibaba. Qwen3.6-27B also beat Alibaba's own 397B model on SWE-bench (77.2 vs 76.2) while running on just 18GB VRAM.
Why it matters: The weekly launch cadence between OpenAI and Anthropic is compressing the evaluation cycle for founders and buyers dramatically — yesterday's benchmark leader is obsolete by next Thursday. For SaaS builders, the bigger signal is Anthropic's $1T valuation without being publicly traded: Claude Code is generating enterprise revenue fast enough to justify it. If you're building on top of these models, the switching cost question just became your most important product decision.
