Anthropic Launches Claude 4.5 Sonnet and New AI Research Agent
Anthropic unveiled Claude 4.5 Sonnet, a significant upgrade to its mid-tier reasoning model with a 1M-token context window and multi-shot reasoning mode. Alongside the model, Anthropic launched a dedicated AI Research Agent product capable of autonomous web browsing, PDF ingestion, and structured report generation. The product integrates with Notion, Google Drive, and MCP servers for extensible knowledge retrieval.

DeepSeek R1 Surpasses GPT-4o on Frontier Benchmarks
DeepSeek's R1 model — a 671B MoE architecture with open weights — achieves parity with GPT-4o on coding and math benchmarks while costing 99% less. The model's 1M-token context and native tool-use support have made it the new default backbone for open-source agent frameworks. DeepSeek also launched a free API tier offering 1M tokens/month.
Key highlights:

Key highlights:
- 5,000+ servers, 40% MoM growth
- 20+ AI platforms with native MCP support
- 150+ enterprises publishing servers
- Dynamic negotiation and state sync in 2.0
