## cubic

cubic targets the review bottleneck. Most AI coding assistants help you write code faster, which then piles more changes onto a review process that is already the slowest part of shipping. cubic reviews the pull request instead: every change is checked not just against the diff but against the rest of the codebase, so it can flag a change that breaks something in another file or another repository. It also learns from your team by turning senior engineers' past review comments into rules that then run automatically on every PR, and lets you write standards in plain English, for example requiring design tokens, forbidding raw environment variables in frontend code, or insisting that migrations use a specific lock timeout.

The workflow is built around keeping merge queues moving. cubic assigns each PR a merge confidence score from one to five, auto-approves genuinely low-risk changes like dependency bumps, documentation, or copy edits, and routes anything risky to a human. It works where developers already are: reviews appear in GitHub with two-way sync, and you can open the same PR in cubic by swapping github.com for cubic.dev in the URL. A desktop app for macOS, Windows, and Linux presents changes in reading order rather than alphabetically, groups related changes, shows a diagram of what changed, and lets you ask questions about the PR. The same review also runs in the terminal before you push, and comments can be picked up by coding agents such as Claude Code, Codex, and Cursor, which push fixes back.

For issues that never appear in a pull request, cubic runs thousands of background AI agents that scan the codebase on a schedule, triage findings, notify owners, and create tickets, with one-click fixes that resolve the ticket once merged. The product advertises top placement on independent code review benchmarks and is used by teams including n8n, Cal.com, Better Auth, and Browser Use. On privacy, cubic states that code is reviewed in real time and never stored or used to train AI, and it is SOC 2 compliant, which matters for teams that cannot send proprietary code to an arbitrary service.

**Pricing & Plans:** Starts free: the Starter tier includes 20 PR reviews per month. Paid per-developer plans are billed yearly with a discount, listed as Team Core at $30 per developer per month with 40,000 reviewed lines, Pro at $79 per developer per month with 80,000 reviewed lines and every feature, and Max at $160 per developer per month with 160,000 reviewed lines. Enterprise adds SSO/SAML, audit logs, and custom terms. cubic is free for open source teams, and extra lines can be purchased as flex capacity at $20 per 10,000 lines.

- **Codebase-aware PR review:** Every pull request is checked against your entire codebase and repo rules, so changes that break code elsewhere, even in another repository, get flagged.
- **Rules learned from your engineers:** Past review comments from senior engineers become automated rules, and you can also express standards in plain English for cubic to enforce on every PR.
- **Merge confidence and auto-approve:** Each PR gets a 1 to 5 safety score, low-risk changes are approved automatically, and risky ones are routed to a human reviewer.
- **Scheduled codebase scans:** Thousands of background agents scan for serious bugs and vulnerabilities on a schedule, triage findings, notify owners, and open tickets with one-click fixes.
- **Reviews in GitHub, terminal, and desktop:** Two-way GitHub sync, the same checks available from the CLI before you push, and a desktop app with reading-order diffs and PR Q&A.

**Strengths:** Reviews against the whole codebase rather than the diff alone; Published per-developer pricing with a free tier and open source support; Works inside GitHub, the terminal, and its own desktop app; Explicit privacy stance: code is not stored and not used for training

**Limitations:** Reviewed-line allowances are metered and reviews pause if you exceed them without flex capacity; Highest-value features such as codebase scans sit in the Pro tier and above; Value is greatest for teams with large, complex repositories on GitHub

## DeepSeek

DeepSeek (Hangzhou DeepSeek Artificial Intelligence Co., Ltd.) is a frontier AI research organization that disrupted the global LLM market by pairing open-weight transparency with breakthrough Mixture-of-Experts (MoE) and reinforcement-learning reasoning efficiency. Following the landmark releases of DeepSeek-V3 and the peer-reviewed DeepSeek-R1 reasoning model, DeepSeek introduced the DeepSeek-V4 generation in 2026—featuring a hybrid attention architecture and a native 1-million-token context window across DeepSeek-V4-Pro (1.6T total parameters, 49B active per token) and DeepSeek-V4.1-Flash (284B total parameters, 13B active per token).

Users can interact with DeepSeek in three ways: completely free through the consumer web portal (chat.deepseek.com) and mobile apps with one-click toggles for deep thinking and live web search; via DeepSeek's hosted, OpenAI-compatible developer API; or by self-hosting DeepSeek's open-weight checkpoints (including V3, R1, Prover-V2, and distilled Qwen/Llama variants) on private infrastructure. The models excel at competitive mathematics, algorithm design, repository-level software engineering, and structured data extraction, with automatic context caching on the API that slashes repeated prompt costs by over 95%.

In late 2026, DeepSeek remains the price-performance benchmark for developers and automation workflows. While the consumer chat interface remains free without a mandatory $20/month subscription tier, the developer API transitioned in late 2026 to two primary endpoints—`deepseek-flash` and `deepseek-v4-pro`—with time-of-day pricing. Off-peak API calls cost just $0.15 per million input tokens ($0.003 on cache hits) and $0.60 per million output tokens on Flash, and $0.66 input / $1.98 output on V4-Pro, making it a fraction of the cost of comparable Western frontier models.

**Pricing & Plans:** Free web and mobile chat app at chat.deepseek.com; pay-as-you-go OpenAI-compatible API with off-peak rates at $0.15/1M input ($0.003 cache hit) and $0.60/1M output for deepseek-flash (V4.1-Flash), and $0.66/1M input ($0.022 cache hit) and $1.98/1M output for deepseek-v4-pro (peak weekday UTC hours bill at 2x).

- **DeepSeek-V4 Hybrid Attention & 1M Context:** Leverages a sparse Mixture-of-Experts architecture (49B active parameters out of 1.6T on V4-Pro) to process up to 1 million tokens with minimal latency and memory overhead.
- **Transparent Chain-of-Thought Reasoning:** Pioneered by DeepSeek-R1 and integrated into V3.2 and V4 thinking modes, exposing step-by-step self-verification for complex math, logic, and code debugging.
- **Automatic Context Caching & Off-Peak API Pricing:** Drops input token costs to $0.003/1M on Flash and $0.022/1M on V4-Pro for cache hits, with 50% lower rates during off-peak UTC hours.
- **Free Consumer Web & Mobile Assistant:** Provides free access at chat.deepseek.com and on iOS/Android with document uploads, reasoning mode, and web search without paywalling core models.
- **Open-Weight Ecosystem & Self-Hosting Freedom:** Offers open weights for DeepSeek-V3, R1, Distill variants, and Prover models on Hugging Face and GitHub so enterprises can deploy within air-gapped environments.

**Strengths:** Completely free consumer web and mobile app with deep reasoning and web search included; Ultra-low API token rates ($0.15/$0.60 on Flash, $0.66/$1.98 on V4-Pro off-peak) with up to 98% savings on cached inputs; Drop-in OpenAI API compatibility makes switching or routing between models effortless; Strong open-weight lineage allows teams to self-host or fine-tune models without vendor lock-in

**Limitations:** Hosted API and web app store data on servers in China, prompting compliance restrictions for some Western enterprises and government agencies; Peak-hour API pricing (01:00–04:00 and 06:00–10:00 UTC on weekdays) doubles per-token costs compared to off-peak rates; Lacks native voice mode, video generation, and productivity suite integrations offered by ChatGPT and Google Gemini
