[AINews] MiniMax 2.7: GLM-5 at 1/3 cost SOTA Open Model

By Unknown

80 score

AI Analysis

As first reported on Reddit yesterday, MiniMax releases MiniMax 2.7, matching Z.ai's GLM-5 SOTA open model performance at roughly 1/3 the cost, with early 'self-evolution' capabilities where the model participates in its own training workflow. The release also includes multi-agent collaboration and finance applications.

Not 2 months after their IPO and first public quarter, MiniMax is back in the news with MiniMax 2.7, a nice bright spot in Chinese Open Models after the changeover in Qwen. They match Z.ai’s GLM-5 SOTA open model from last month, but the story is efficiency here (see green quadrant in Artificial Analysis’ chart):The team calls out “Early Echoes of Self-Evolution”, calling it “our first model deeply participating in its own evolution.”, recalling Karpathy’

Meet Mamba-3: A New State Space Model Frontier with 2x Smaller States and Enhanced MIMO Decoding Hardware Efficiency

By Asif Razzaq

74 score

AI Analysis

As first reported in Social on March 18th, Researchers from CMU, Princeton, Together AI, and Cartesia AI introduced Mamba-3, a state space model with 2x smaller states and enhanced hardware efficiency through exponential-trapezoidal discretization, complex-valued states, and MIMO decoding. The model takes an 'inference-first' design approach to address Transformer scaling bottlenecks.

The scaling of inference-time compute has become a primary driver for Large Language Model (LLM) performance, shifting architectural focus toward inference efficiency alongside model quality. While Transformer-based architectures remain the standard, their quadratic computational complexity and linear memory requirements create significant deployment bottlenecks. A team of researchers from Carnegie Mellon University (CMU), Princeton University, Together AI, and Cartesia AI have introduced Mamba-

AI Analysis

Continuing our coverage from yesterday, NVIDIA announced the Agent Toolkit at GTC 2026, an open-source stack featuring OpenShell for policy-based security guardrails for autonomous AI agents in enterprise environments. The toolkit aims to standardize trust and safety for agents operating inside enterprise systems.

The NVIDIA Agent Toolkit is Jensen Huang’s answer to the question enterprises keep asking: how do we put AI agents to work without losing control of our data and our liability? Announced at GTC 2026 in San Jose on March 16, the NVIDIA Agent Toolkit is an open-source software stack designed to help enterprises and developers build autonomous AI agents. What’s stalling broader deployment is trust. Agents that can take action inside enterprise systems need guardrails, and until now, tho

AI Analysis

Google released an open-source MCP server for Colab, enabling AI agents (Claude Code, Gemini CLI, etc.) to programmatically create, modify, and execute code in cloud-hosted Jupyter notebooks with GPU access. This bridges AI agents to real compute environments using the MCP standard.

Google has officially released the Colab MCP Server, an implementation of the Model Context Protocol (MCP) that enables AI agents to interact directly with the Google Colab environment. This integration moves beyond simple code generation by providing agents with programmatic access to create, modify, and execute Python code within cloud-hosted Jupyter notebooks. This represents a shift from manual code execution to ‘agentic’ orchestration. By adopting the MCP standard, Google all

Visa prepares payment systems for AI agent-initiated transactions

By Muhammad Zulhusni

65 score

AI Analysis

Visa launches its 'Agentic Ready' programme in Europe, testing AI agent-initiated payment transactions with banks including Commerzbank and DZ Bank. The initiative prepares payment infrastructure for a future where software agents make purchases on behalf of users.

Payments rely on a simple model: a person decides to buy something, and a bank or card network processes the transaction. That model is starting to change as Visa tests how AI agents can initiate payments. New work in the banking sector suggests that, in some cases, software agents may soon take on that role. A recent example comes from Visa, which is rolling out its “Agentic Ready” programme in Europe to test how financial systems handle AI-initiated transactions. The effort involve
