PrimeIntellect
Decentralized AI lab — Prime Agent, the self-improving RLM agent.
PrimeIntellect, the lab known for decentralized training and the INTELLECT model series, open-sourced Prime Agent: a recursive-language-model agent for coding and long-running autonomous tasks whose harness famously took Opus 5 from ~30% to 95.5% on ARC-AGI-3 — evidence that the harness can matter more than the model.

PrimeIntellect's Prime Agent: a self-improving RLM agent
PrimeIntellect open-sources Prime Agent, a recursive-language-model agent whose harness runs sub-agents as function calls inside a persistent IPython REPL. The launch post reports its harness taking Opus 5 from ~30% to 95.5% on ARC-AGI-3 — the sharpest evidence yet that harness engineering can beat model selection.
EverMind open-sources Raven — 'the harness of harnesses'
EverMind AI releases Raven, a trusted, persistent, self-evolving multi-agent ecosystem built for recursive self-improvement — agents that modify their own harness under governance. The Show HN thread became a running debate on how much autonomy a harness should hand an agent over itself.

Devin, the AI software engineer, and the Windsurf IDE.
Cognition builds Devin, an autonomous AI software engineer that plans and executes engineering tasks end-to-end, and acquired the Windsurf agentic IDE in 2025. One of the defining startups of the coding-agent wave.
Modal
Serverless cloud built for AI and agentic compute.
Modal lets teams run inference, fine-tuning and arbitrary agent workloads as serverless Python without managing infrastructure — a common substrate for harness backends at scale.
Temporal
Durable execution for long-running agent workflows.
Temporal's durable execution engine is widely adopted to make agent pipelines reliable: state survives crashes, retries are automatic, and workflows run for minutes or months. A key piece of serious harness infrastructure.
