🆕 v0.7.0 Changes

• Creative Open Source License — MIT-based with attribution + AI training permission
• SOP.md — Complete Standard Operating Procedures (install, setup, workflows, troubleshooting)
• NA-safe input validation — All functions handle NULL/NA gracefully
• Custom system_prompt preserved — Small-model optimization no longer overwrites user prompts
• Base packages removed from Imports — No more installation failures
• RStudio Viewer dashboard — raix_dashboard() opens inside RStudio
• White/navy hero image — Clean, minimalist

Previous Features (v0.5.x)

• 34 functions: Chat · Code Gen · Developer Agent · Compute Engine
• Small LLM auto-detection and optimization
• Auto-detect Ollama with model warmup
• Windows-safe TCP port checking
• Smart retry with timeout detection
• 13+ AI providers | 33 man pages | Full Shiny dashboard

v0.5.1 — Production Stable: Windows-Safe + Auto-Warmup

raix v0.5.1 — Production Stable

Critical Fixes

Windows-safe auto-detection — TCP port check (socketConnection) replaces curl for backend detection. No more segfaults on Windows when checking if Ollama is running.

Model pre-warming — On setup, raix sends a warmup request to load the model into RAM. Your first real call never times out.

Smart retry — Detects cold-start vs. connection failure. First call gets 180s timeout, subsequent calls 120s. Automatic retry if model is still loading.

Helpful error messages — Distinguishes between:

• Model loading into memory → suggests waiting and retrying
• Ollama not running → shows start command
• Model not found → shows pull command
• Connection refused → suggests switching provider

All Features (v0.5.x)

• 33 functions: Chat, Code Gen, Developer Agent, Compute Engine
• 13+ providers with custom endpoint support
• Small LLM optimization (auto-detects 7B-9B models)
• Modern Shiny GUI with chat bubbles and typing indicators
• Developer agent: solve, script, notebook, pipeline, compile, benchmark
• Cross-language: terminal, Python, C++/Rcpp, shell scripts

v0.5.0 — Developer Agent + Small LLM Optimized

raix v0.5.0 — R + AI + eXperiment

What's New

Developer Agent — raix now acts as an autonomous coding agent:

• raix_solve() — English problem → complete R solution with package selection, plan, and code
• raix_script() — Generate .R scripts from descriptions
• raix_notebook() — Generate .Rmd notebooks ready to knit
• raix_project() — Scan directories, read files, build full AI context
• raix_package() — Find the best R package for any task
• raix_read() — Read files with AI summarization
• raix_write() — Write AI-generated content directly to files

Small LLM Optimization — Auto-detects local models (7B-9B):

• Detects qwen2.5-coder, phi3.5, gemma2, llama3.2, and more
• Auto-switches to concise, directive prompts for reliable results
• raix_small_mode() toggle for manual control
• Higher temperature (0.3) and lower max_tokens (1024) for small models

Redesigned GUI — Modern chat interface:

• Chat bubbles with avatars, typing indicators
• Auto-connect on launch, quick-prompt pills
• Collapsible sidebar, dark/light design

One-Click Setup — raix_setup() auto-detects running Ollama, LM Studio, vLLM, or API keys from environment variables. Zero configuration needed.

Complete Rename — All air_* → raix_*. 25 functions total.
