Free open-source, config-driven LLM fine-tuning framework covering full and parameter-efficient fine-tuning (LoRA, QLoRA), preference tuning (DPO, KTO, ORPO), and reinforcement learning across many model families through declarative YAML configs.

Lightweight open-source serving framework for building custom AI model inference APIs by defining a LitAPI with setup and predict methods, with batching, streaming, multi-GPU autoscaling, OpenAI-compatible endpoints, and support for compound, multimodal, RAG, and agent pipelines.

Open-source status companion for Claude Code and Codex with live local session state, your-turn alerts, usage views, and native macOS and Windows applications.

Source-backed rules for reviewing AI-generated endpoints and data-access code before merge for insecure direct object reference risk, covering per-request object-level authorization checks, scoped database lookups, identifier exposure, and consistent enforcement across read, write, and admin operations.

Source-backed rules for reviewing AI-generated code that deserializes data before merge for insecure deserialization risk, covering native serialization formats (pickle, PyYAML, Java Serializable) that can execute arbitrary code on untrusted input, safe data-interchange alternatives, and class allowlisting/integrity checks when native formats can't be avoided.

Source-backed rules for reviewing AI-generated code that binds request parameters to model/entity objects before merge for mass assignment risk, covering allowlist field binding, DTOs that exclude sensitive fields, and the framework-specific autobinding features that make this easy to introduce by default.

Source-backed rules for reviewing AI-generated redirect and forward logic before merge for open redirect risk, covering allowlist-based destination validation, relative-path/indexed-mapping alternatives to raw URLs, and the privilege-escalation and phishing impact of an unvalidated redirect target.

Source-backed rules for reviewing AI-generated code that builds or runs operating-system commands, shell invocations, or subprocesses before merge for command injection and argument injection risk, covering library alternatives to shelling out, array-form process APIs, allowlist input validation, and least-privilege execution.

Source-backed rules for reviewing AI-generated JavaScript/TypeScript code before merge for prototype pollution risk, covering unsafe recursive merge/clone/assign helpers on untrusted input, proto and constructor-prototype key handling, and safer alternatives like Map, Set, and Object.create(null).

Source-backed rules for reviewing AI-generated code that renders untrusted data into HTML, JavaScript, URLs, or CSS before merge for cross-site scripting risk, covering context-correct output encoding, dangerous DOM sinks, HTML sanitization, and Content-Security-Policy as defense in depth.
