# Oh My Pi v17.3.0: breaking config changes, new OpenAI models, per-agent advisors, Nix support

> Breaking: the global `advisor.subagents` setting is removed (per-agent advisor config replaces it), `withGeminiThinkingLoopGuard` is renamed to `withThinkingLoopGuard`, and `OpenAICompat.enableGeminiThinkingLoopGuard` is removed. New: first-party OpenAI Daybreak Blue, Daybreak Red, and GPT-5.6 Cyber models; per-agent advisors via frontmatter or settings; redesigned /agents fullscreen hub; Nix support with reproducible builds, NixOS/Home Manager modules; Astral `ty` as a Python LSP fallback. Multiple fixes across Anthropic cache pricing, Ollama chat adapter, xAI usage reporting, and Grok thinking-loop guard. Legacy cost-estimation machinery for OpenCode Go is removed.

## What changed


**Breaking changes**
- Removed global `advisor.subagents` setting; subagent advisors are now per-agent via frontmatter or `task.agentAdvisor` (auto-migration from `advisor.subagents: true`)
- Renamed `withGeminiThinkingLoopGuard` to `withThinkingLoopGuard` (guards Gemini, DeepSeek, and Grok model-id families)
- Removed `OpenAICompat.enableGeminiThinkingLoopGuard`; thinking-loop eligibility is derived solely from model ID family

**Added**
- First-party OpenAI Daybreak Blue, Daybreak Red, and GPT-5.6 Cyber models with full API pricing (including long-context rates above 272K input), token limits, tools, and reasoning effort controls (off/low/medium/high/xhigh/max)
- Per-agent advisors configured via frontmatter `advisor` field or `task.agentAdvisor` setting
- Redesigned /agents fullscreen hub with scope sidebar, type-to-filter search, pinned detail pane, mouse support, and interactive property chips
- Nix support: reproducible source builds for Linux and macOS, pinned development shell, NixOS and Home Manager modules, offline Bun dependency support
- Astral `ty` as a built-in fallback Python LSP server (ordered behind pyright, basedpyright, pylsp)
- `calculateUncachedInputCost()` for prompt pricing against active context-length tiers

**Fixes**
- Anthropic cache-write pricing correctly handles mixed 5-minute and 1-hour TTL usage
- Ollama chat adapter forwards sampling parameters (temperature, topP) to the provider
- OpenAI agent turns no longer end prematurely after a web search with no visible answer
- Completed model streams release provider concurrency permits promptly
- xAI usage reporting no longer falls back to stale cache at weekly cycle boundaries
- Together AI login validates via authenticated models list instead of hardcoded model
- Grok runaway thinking streams caught by the thinking-loop guard
- DeepSeek V4 Flash and V4 Pro apply correct effort contracts (low/high/max) across all transports
- Image input support for qwen3.8-max and newer models in DashScope compatible-mode
- Perplexity email-OTP login preserves session cookies
- Various credential-health, login, and config resolution fixes

**Removed**
- Legacy local request-cost estimation machinery and database schemas for OpenCode Go
