TypeSafe AI released Jev, a new model class designed for automation that outputs type-safe structured decisions instead of text, running 40-200x faster and cheaper than existing LLMs on decision-making tasks. Unlike traditional language models, Jev can't hallucinate, always provides confidence scores, and costs nothing for output tokens.

• Jev achieves comparable intelligence to frontier LLMs on decision tasks while being 40-200x faster (70-500ms vs 3-329 seconds) and drastically cheaper ($0.042 per billion input tokens, free output tokens vs $0.20-$10 per million input tokens for LLMs).
• The model uses a new training method called Reinforcement Learning for Calibrated Decisions (RLCD) that optimizes for accurate probability estimates rather than human preference, and generates all outputs in parallel instead of sequentially, eliminating hallucinations and type errors.
• Jev trades away general text generation to specialize in structured outputs that slot directly into software workflows as fuzzy decision rules—classifying, routing, scoring, and branching without requiring human validation or parsing.

TypeSafe AI released Jev, a new type of AI model designed for automation and structured decision-making rather than text generation. It's 40-200x faster and 444x cheaper than existing large language models for specific tasks, with guaranteed type-safety and calibrated confidence scores instead of hallucinations.

• Jev generates all outputs in parallel rather than token-by-token, achieving 70-500ms response times versus 3-329 seconds for frontier models, while outputting structured data instead of strings
• The model uses a new training method called Reinforcement Learning for Calibrated Decisions (RLCD) that optimizes for epistemically honest probability estimates rather than human preference, making it reliable enough to embed in production software workflows
• Pricing is $0.042 per billion input tokens with free output tokens, versus $0.20-$10 per billion for existing models, with claims backed by publicly available workflow evaluations showing performance across complex automation tasks

Cline, a VS Code extension used by 11 million developers, now has a standalone desktop app that lets you run multiple AI agents in parallel, choose from 300+ models, and automate recurring tasks. You can also import conversations from Claude Code or other agents and continue them with cheaper open-weight models.

• Run parallel agents simultaneously with scheduled cron job automations for recurring work like nightly repo checks or weekly documentation updates.
• Switch between 300+ models across 50+ providers, or use local models—you can even mix different models for planning versus execution.
• Import tasks and conversations from Claude Code, Codex, or other agents to continue work without starting over, useful when hitting subscription limits.
• The app extends beyond coding to research, document review, reporting, and other non-code work through plugins, MCP servers, and skills.
