Anthropic released Claude Opus 4.8 with unchanged pricing, new inference‑strength controls, Dynamic Workflows for massive tasks, a fast mode 2.5× quicker and three‑times cheaper, and benchmark results showing its agent capabilities surpass GPT‑5.5 while improving honesty and alignment.
The DeepSeek‑V4 preview details two model variants—Pro and Flash—with trillion‑scale parameters, outlines benchmark scores that surpass or match leading overseas models across code generation, real‑world fixes, engineering tasks, and world knowledge, and explains core innovations, pricing, API endpoints, and open‑source licensing.
Google’s Gemini 3.1 Pro, the latest upgrade to the Gemini 3 series, achieves a verified 77.1 % score on the ARC‑AGI‑2 reasoning benchmark—more than double the performance of Gemini 3 Pro—while leading in GPQA, LiveCodeBench Pro, SWE‑Bench Verified, and MMMLU tests, and is now being rolled out to developers, enterprises and consumers with detailed pricing and integration options.
Google's Gemini 3.1 Pro preview raises reasoning benchmark scores dramatically, offers new pricing tiers, and is already integrated into Gemini API, CLI, Vertex AI, and consumer apps, while community demos showcase SVG animation, real‑time dashboards, 3D simulations, and heat‑transfer analysis.
OpenAI’s GPT‑5.2 launch introduces three specialized modes, achieves a record 55.6% score on SWE‑Bench Pro, demonstrates strong front‑end generation, adds a /compact API for long‑context efficiency, offers tiered pricing with cache discounts, and improves safety for younger users.
OpenAI introduced the O3‑Pro multimodal deep‑reasoning model with an 80% price cut for O3, detailed its training via large‑scale reinforcement learning, compared its capabilities and costs against GPT‑4o, GPT‑4.1 and O3‑Pro, listed its core specs, limitations, access methods, and presented benchmark tests that highlight both strengths and weaknesses.
