## 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

## StackAI

. What StackAI is

StackAI is an enterprise AI agent platform aimed at IT and enterprise architecture teams. It provides the building blocks to turn a manual, time-consuming process into a working agent in minutes: a visual canvas for composing agents and multi-step flows, modules for storage, vision, text-to-speech and speech-to-text, and code steps in Python or JavaScript when you need custom logic.

Agents are only as useful as the systems they can touch, so the platform ships with 500+ enterprise integrations that let an agent read, write and execute tasks inside your existing CRM, ticketing, document and collaboration tools. Knowledge bases can be grounded in your own material through document upload, web scraping, Google Drive and Notion connectors, with readers for PDF, Word and PowerPoint. Because it is model-agnostic, each step can route to whichever LLM performs best for that job.

Governance is the differentiator. StackAI is certified to SOC 2 Type II, HIPAA, GDPR and ISO 27001, offers SSO, access control and audit logs, and supports human review at critical decision points. It can run multi-tenant, in your VPC or fully on-premise. The company announced that it has been acquired by Asana, adding human-agent workflow management to the picture. Pricing is a $0 Free plan with 500 runs per month, 2 projects and 1 seat, and a custom Enterprise tier for teams that need unlimited scale, dedicated engineers and regulated deployment options.

**Pricing & Plans:** StackAI has a $0 Free plan that includes 500 runs per month, 2 projects and 1 seat with community support. The Enterprise tier is custom-priced and includes a custom number of runs and seats, unlimited projects, all features and data loaders, dedicated infrastructure and solution engineers, on-premise and VPC deployment, access control, SSO, and SOC 2 / HIPAA / GDPR compliance.

- **No-Code Agentic Workflows:** Assemble agents and multi-step flows on a visual canvas with modules for agents, storage, vision, text-to-speech and speech-to-text, then add Python or JavaScript logic when you need it.
- **500+ Enterprise Integrations:** Connect agents to 500+ enterprise systems so they can read, write and execute tasks inside your CRM, helpdesk, document stores and collaboration tools.
- **Knowledge Bases and Data Loaders:** Ground agents in your own material with document upload, web scraping, Google Drive and Notion connectors, and document readers for PDF, Word and PowerPoint.
- **Security, Governance and Deployment Choice:** Deploy in multi-tenant cloud, your own VPC or on-premise, with SSO, role-based access control, audit logs and human review at critical decision points.
- **Model-Agnostic LLM Routing:** Choose the best-performing model for each step of a workflow instead of standardising on a single provider.
- **Ready-Made Agent Templates:** Pre-built agents for SOW intake, service desk replies, anti-money-laundering screening, call compliance extraction and internal L&D Q&A.

**Strengths:** Visual no-code builder gets agents from process to production quickly; 500+ enterprise integrations let agents act inside existing systems; Model-agnostic routing across leading LLMs; SOC 2 Type II, HIPAA, GDPR and ISO 27001 certifications

**Limitations:** Advanced capabilities such as on-prem, VPC deployment and SSO are Enterprise-only; The free plan is tight at 500 runs per month, 2 projects and a single seat; No public self-serve mid-tier pricing between Free and Enterprise; Enterprise focus means more setup and governance overhead than a lightweight automation tool
