## ChatGPT

ChatGPT has evolved from a single conversational chatbot into OpenAI's comprehensive AI workspace for consumers, software engineers, and enterprises. While legacy directory listings still reference the 2023 'ChatGPT-4' era, the platform in late 2026 runs on OpenAI's tiered reasoning architecture: Free and Go accounts default to GPT-5.6 Luna, Plus subscribers gain GPT-5.6 Sol with configurable Instant, Medium, and High thinking levels, and Pro and Business Premium subscribers unlock GPT-6 Pro, GPT-6 Astra, and GPT-5.6 Sol Pro with context windows reaching up to 400K tokens in reasoning mode.

Beyond text generation, ChatGPT integrates dedicated agentic and multimodal workflows directly into the interface. Users can launch Deep Research to synthesize multi-step cited reports across the live web, collaborate inside Canvas for side-by-side document and code editing, and run autonomous software engineering tasks through ChatGPT Work and Codex—which execute, test, and refactor code across full repositories. Real-time Advanced Voice Mode with live camera and screen sharing, native image generation, and direct connectors for Google Drive, GitHub, SharePoint, and Notion allow teams to query internal knowledge bases without manual file uploads.

In 2026, OpenAI restructured ChatGPT's pricing ladder to span casual users to heavy agentic builders. The $8/month Go tier bridges the gap between Free and the standard $20/month Plus plan, while the expanded Pro lineup ($100, $200, and $500/month) removes the five-hour rolling usage cap in Work and Codex, unlocks Astra Ultrafast on Pro 500, and rebates 100% of the monthly subscription fee in OpenAI API credits. Organizations can deploy ChatGPT Business (formerly Team) starting at $20/seat/month billed annually with SSO, admin governance, and contractual guarantees that company data is never used for model training.

**Pricing & Plans:** Free tier ($0) on GPT-5.6 Luna; ChatGPT Go at $8/mo; ChatGPT Plus at $20/mo; ChatGPT Pro tiers at $100/mo, $200/mo, and $500/mo (with matching monthly API credits); Business Standard at $20/user/mo billed annually ($25/mo monthly) and Business Premium at $100-$125/user/mo.

- **GPT-6 Astra & GPT-5.6 Adaptive Reasoning:** Automatically routes prompts or lets users select between Instant responses and Medium, High, or Extra High thinking depth across GPT-5.6 Luna, GPT-5.6 Sol, and flagship GPT-6 Pro/Astra models.
- **ChatGPT Work & Cloud Codex Agents:** Asynchronous software engineering and task agents that clone repositories, run terminal tests in sandboxed environments, resolve complex bugs, and submit pull requests.
- **Autonomous Deep Research:** Browses dozens of primary web sources, academic papers, and connected workspace documents over several minutes to compile structured, citation-backed analytical reports.
- **Interactive Canvas & Multimodal Voice:** Provides a split-screen editor for inline prose and code revisions alongside low-latency voice conversations with live screen and camera grounding.
- **Pro API Credit Rebate & Workspace Connectors:** Every Pro tier ($100, $200, $500/mo) includes its full subscription value in monthly OpenAI API credits, plus native integrations with GitHub, Google Drive, and Microsoft 365.

**Strengths:** Full monthly fee rebated as usable OpenAI API credits across all three Pro tiers ($100, $200, and $500/mo); Removes the 5-hour rolling usage cap in ChatGPT Work and Codex on Pro plans for uninterrupted agentic coding; Budget-friendly $8/mo ChatGPT Go plan makes expanded memory and higher daily message caps accessible below Plus; Industry-leading multimodal ecosystem combining Deep Research, Canvas, Advanced Voice, and native image generation

**Limitations:** Plus ($20/mo) enforces 5-hour rolling message caps in Work and Codex and excludes GPT-6 Pro in standard chat; A five-tier consumer pricing ladder (Free, Go, Plus, and three separate Pro tiers) makes choosing the right allowance confusing; Instant context window on lower tiers (54K on Plus vs 128K on Pro) is smaller than Google Gemini's 1M-token standard window

## OpenSilver

OpenSilver rebuilds the Microsoft Silverlight and WPF programming model on top of .NET and WebAssembly, so a codebase written in C#, VB or F# with XAML keeps working in Chrome, Firefox, Safari, Windows, macOS and Android. Teams that own a legacy Silverlight line-of-business application — or a Windows-only WPF desktop app — can move it to the browser while reusing over 95% of the original source, keeping screens visually identical so no user retraining or documentation rewrite is needed.

The framework ships with enterprise-oriented controls and library compatibility, including RIA Services and LightSwitch support, and the 3.3 release introduced an AI-enhanced drag-and-drop UI designer, the ability to host Blazor components directly inside XAML applications, and MAUI Hybrid integration. It also interoperates with Blazor, React and Angular when a team wants to mix stacks rather than migrate everything at once.

The core technology stack is free under the MIT license and can be downloaded as an SDK or tried instantly in the zero-setup XAML.io online IDE. For organizations that prefer not to run the migration themselves, Userware offers a commercial end-to-end migration service, support plans and pro services — which is where the paid side of the offering sits.

**Pricing & Plans:** The OpenSilver framework itself is free and open source under the MIT license, including the SDK and the online XAML.io IDE. Paid options come through Userware: commercial support plan subscriptions, pro services, and end-to-end WPF/Silverlight migration engagements quoted per project.

- **95%+ code reuse for legacy apps:** Recompile existing Silverlight or WPF C#, VB and F# code into a WebAssembly app that runs in any modern browser, avoiding a costly rewrite.
- **AI-enhanced visual designer:** OpenSilver 3.3 adds an AI-assisted drag-and-drop UI designer for building and editing XAML screens faster.
- **Blazor and MAUI interop:** Host Blazor components directly inside XAML applications and integrate with MAUI Hybrid, plus mix in React or Angular where useful.
- **Enterprise library compatibility:** Keeps support for RIA Services, LightSwitch and common third-party controls so established business apps keep working.
- **Zero-setup online IDE:** Try the framework immediately in the browser at XAML.io with no install and no signup, or download the SDK locally.

**Strengths:** Reuses the large majority of existing Silverlight/WPF code and preserves the pixel-level UI; Open-source MIT core with an installable SDK and a free in-browser IDE; Professional migration services and support plans available when you need them; Broad target coverage: all major browsers plus Windows, macOS and Android

**Limitations:** Targeted at teams with legacy .NET code rather than greenfield developers; Enterprise-grade migration and support are commercial and quoted per project; WebAssembly output can still be heavier than a hand-written modern front-end
