Software layers that wrap an AI model with tools, memory, prompts, and control loops so it can carry out multi-step tasks as an agent.
Earendil's Pi 1.0, an agent harness whose website once advertised "No MCP", now builds MCP into its core. The team ties the reversal to Codemode, a JavaScript interpreter beside the harness loop that lets the model batch MCP calls into one script.

MIT CSAIL's VISTA harness raised Claude Opus 5.0's ARC-AGI-3 action-efficiency score from 40.68 to 100 without retraining or replacing the model. The comparison holds the model fixed, so the lift comes from the interface built around it.

Cohere's North 2 agent platform lets administrators track token use down to each user and agent and cap spending across the whole company. Cohere is selling to whoever answers for agent cost and risk, and the launch report backs that with three customer accounts and no prices.

Jabali AI founder Vatsal Bhardwaj argues that the engineering around a model explains the 95% of enterprise AI pilots that MIT found showed no P&L impact. His five rebuilds in two years point to a standing budget, on evidence from one games company.

SpaceX says Grok 4.7 averages $4.69 per task on CursorBench 4.0, which was built by Cursor, one of its own acquisitions. The rivals it undercut were running quality-first configurations, and GPT-6 Astra beat it on chip design.
