Pricing
PaidClaude Code is included in every paid Claude plan rather than sold separately. Pro is $17/month billed annually ($200 upfront) or $20/month billed monthly. Max starts at $100/month for 5x the usage of Pro, or $200/month for 20x the usage. Team offers Standard seats at $20/seat/month billed annually ($25/month billed monthly) and Premium seats (5x more usage) at $100/seat/month billed annually ($125/month billed monthly), with the ability to mix and match seat types. Enterprise is $20/seat/month plus usage billed at standard API rates, billed annually, and adds SCIM, audit logs, role-based access, custom data retention, and a HIPAA-ready offering. All plans share a single usage pool between Claude Code and Claude.ai chat activity, resetting on a rolling five-hour session window with weekly caps on paid plans; usage credits can be enabled on paid plans to continue working at standard API rates after hitting a limit. Claude Code is not available on the Free plan, but can also be accessed pay-as-you-go through a Claude Console (API) account.
PaidThe OpenAI API uses pay-as-you-go, per-token pricing that varies by model. GPT-5.6 Sol, built for complex reasoning and coding, costs $5.00 per 1M input tokens and $30.00 per 1M output tokens with a 1.05M context length. GPT-5.6 Terra, balancing intelligence and cost, costs $2.00 per 1M input tokens and $12.00 per 1M output tokens. GPT-5.6 Luna, designed for cost-sensitive, high-volume workloads, costs $0.20 per 1M input tokens and $1.20 per 1M output tokens. All three share a 1.05M context length and 128K max output tokens. Additional costs apply for fine-tuning, evals, and specialized tools like web search or file search depending on usage. New accounts must add billing details before making live API calls, and there is no free-tier token quota; enterprise organizations can contact sales for custom pricing, dedicated support, and advanced data residency and retention controls.

Summary
Anthropic's agentic coding tool that lives in your terminal
Developer platform for GPT models, AI agents, and real-time voice
Claude Code Pros & Cons
Pros
- Deep codebase awareness that spans the full project rather than just the open file
- Fully scriptable and composable, fitting naturally into CI pipelines and existing terminal workflows
- MCP support connects it to external tools like Google Drive, Figma, Slack, and Jira
- Included in every paid Claude plan rather than requiring a separate subscription
- Available across terminal, IDE, desktop app, and browser for flexible workflows
Cons
- Not included in the Free plan; requires a paid Pro, Max, Team, or Enterprise subscription, or a pay-as-you-go API account
- Usage is pooled with regular Claude chat activity on subscription plans, so heavy terminal sessions can eat into the same limits used for everyday chatting
- Terminal-first design means it lacks the point-and-click familiarity of a full GUI IDE for developers who prefer that workflow
- Heavy agentic or automated workloads can run up token costs quickly if not managed with context management commands
- Enterprise-grade controls like SSO, SCIM, and audit logs require Team or Enterprise plans rather than being available on Pro
OpenAI API Pros & Cons
Pros
- Access to frontier GPT-5.6 models spanning a full range of intelligence and cost tiers
- Comprehensive platform covering text, agents, voice, and multimodal use cases in one place
- Agents SDK and built-in tools simplify building production-grade autonomous agents
- Strong enterprise security posture, including SOC 2 Type 2 and HIPAA BAAs
- No training on API business data by default, with zero data retention available by request
- Extensive documentation, cookbook examples, and an active developer community
Cons
- Pay-as-you-go token costs can scale quickly for high-volume or long-context applications
- New accounts must add billing details before making API calls, with no ongoing free-tier quota
- Frontier reasoning models like GPT-5.6 Sol carry premium per-token pricing versus smaller models
- Enterprise features like dedicated support and advanced data residency require contacting sales
- Rate limits and model access can vary by usage tier, requiring spend history to unlock higher limits
