After the U.S. Commerce Department forced Anthropic to shut down Fable 5 and Mythos 5, Zhipu released GLM 5.2 as an open‑source coding model; the author evaluates its coding and agent capabilities, compares it with Claude and Opus, and highlights its strengths, limitations, and real‑world task performance.
The newly released Kimi K2.7 Code, a 1‑trillion‑parameter mixture‑of‑experts model that activates only 32 B parameters per inference, offers a 256 K context window, supports multimodal input, improves benchmark scores by up to 31.5 % over K2.6, reduces inference token usage by about 30 %, and achieves an 81.1 MCP tool‑call score surpassing Claude Opus 4.8, while providing a CLI installation command and usage guidelines.
Anthropic’s Claude Sonnet 4.5, promoted as the world’s best coding model, achieves top scores on SWE‑bench Verified, runs continuously for over 30 hours, outperforms competitors on OSWorld and multiple agentic tests, adds extensive safety features, and introduces a revamped Claude Code suite with VS Code, terminal, and Agent SDK enhancements.
