12 alternatives to Overmind
Inferock routes LLM calls through a measurement layer that records quality, latency, cost and failed calls, and offers serverless and dedicated inference with service credits for eligible failures.
Jev by TypeSafe AI is a model API that takes state plus typed questions and returns Choice, Score and true/false answers with calibrated probabilities instead of generated text.
Mercury is Inception's family of diffusion large language models, served through an OpenAI-compatible API. Mercury 3, launched in October 2026, is the company's flagship reasoning model with a 1M-token context.
Harness² is an Apache-2.0 research framework from Google Cloud AI Research that automatically refines an LLM agent's harness (prompts, tools, memory, skills and more) for each task and carries lessons forward to future tasks, without changing model weights.
shim-cli is a free, Apache-2.0 command-line tool that hooks into Claude Code, Codex, Copilot CLI and VS Code to find secrets and personal data in what an agent sends, mask it where the client allows, and report session tokens and cost.
CosVoice gives your AI Chief of Staff a real US phone number and email. It calls, answers, and sends written summaries.
NitroStack is a platform for building, testing and hosting Model Context Protocol (MCP) servers. It combines an open-source TypeScript SDK, a desktop IDE called NitroStudio and a serverless host called NitroCloud.
fal is a generative media platform for developers: one API to 1,500+ image, video, audio and 3D models, plus serverless GPU deployment for custom models and dedicated GPU clusters for training.
