GLM-4.1V
GLM-4.1V
GLM-4.1V is a vision-language model, providing a powerful, compact multimodal model designed for reasoning and perception across images, text, and documents. The 9-billion-parameter variant (GLM-4.1V-9B-Thinking) is built on the GLM-4-9B foundation and enhanced through a specialized training paradigm using Reinforcement Learning with Curriculum Sampling (RLCS). It supports a 64k-token context window and accepts high-resolution inputs (up to 4K images, any aspect ratio), enabling it to handle complex tasks such as optical character recognition, image captioning, chart and document parsing, video and scene understanding, GUI-agent workflows (e.g., interpreting screenshots, recognizing UI elements), and general vision-language reasoning. In benchmark evaluations at the 10 B-parameter scale, GLM-4.1V-9B-Thinking achieved top performance on 23 of 28 tasks.

GLM-4.5
GLM-4.5
GLM‑4.5 is Z.ai’s latest flagship model in the GLM family, engineered with 355 billion total parameters (32 billion active) and a companion GLM‑4.5‑Air variant (106 billion total, 12 billion active) to unify advanced reasoning, coding, and agentic capabilities in one architecture. It operates in a “thinking” mode for complex, multi‑step reasoning and tool use, and a “non‑thinking” mode for instant responses, supporting up to 128 K token context length and native function calling. Available via the Z.ai chat platform and API, with open weights on HuggingFace and ModelScope, GLM‑4.5 ingests diverse inputs to solve general problem‑solving, common‑sense reasoning, coding from scratch or within existing projects, and end‑to‑end agent workflows such as web browsing and slide generation. Built on a Mixture‑of‑Experts design with loss‑free balance routing, grouped‑query attention, and an MTP layer for speculative decoding, it delivers enterprise‑grade performance.

    "HUGE upgrade"

    Posted 2025-05-22

    Pros: I just started using Claude Sonnet 4 today, and it's already exceeded my expectations. The improvements over Sonnet 3.7 are noticeable, especially in how it handles complex instructions. It’s far better at reasoning and understanding context, delivering answers with precision. The new memory capabilities, like extracting and storing key facts, make the interactions feel more continuous and intelligent. Plus, its ability to use tools in parallel during extended thinking adds another layer of depth, making it ideal for more intricate tasks.

    Cons: While the overall performance is impressive, there are minor areas that could still use refinement. Occasionally, the responses take a bit longer when working on more advanced queries.

    Overall: In general, Claude Sonnet 4 is a remarkable upgrade. The model brings powerful performance and improved steerability, making it an excellent choice for those seeking both capability and practicality. I’m looking forward to using it more, as it’s clear that it will only get better with more interaction. Whether you’re coding, problem-solving, or simply looking for a reliable AI assistant, Claude Sonnet 4 is definitely worth trying.
