## 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

## Replyless

Replyless takes a different angle from the usual "AI sidecar bolted onto Gmail." It is an AI-native email app in its own right, but it still sits on top of the mailbox you already use. Gmail, Outlook, and Zoho Mail accounts are connected and merged into one list, with actions syncing back to the provider so your mail is never locked in.

The core idea is forced clarity. Focus mode turns a single noisy inbox into two tabs: Primary for people and threads that need a reply, and Everything else for receipts, newsletters, and promotions. You can also create named views such as Clients, Newsletter, or Payments. Sorting corrects itself as you move things, and urgent emails are pushed to the top of each view. Pressing Command-K opens a command centre for jumping to a view, drafting a reply, or setting a reminder.

AI does the writing and the routine work. Replyless reads the entire thread before drafting an answer in your voice, learns from your edits, and keeps saved snippets ready in the compose toolbar. Beyond that, agents can run background jobs you describe in plain language - a morning digest of unread mail, calendar, and open loops, or pushing invoices to Slack or Notion. Replyless is available on web, macOS, iOS, and Android, keeps each account's data scoped to its own connection, and states that it is GDPR compliant. It is an independent product and is not endorsed by OpenAI, Anthropic, or Google.

**Pricing & Plans:** 7-day free trial of the full Basics plan, plus a free Cleaner tier. Basics is $15 per user/month (5,000 AI credits, unlimited connections and workflow runs) or $10.50/month billed yearly at 30% off. Pro is $30 per user/month for unlimited AI usage. A $299 one-time Lifetime plan and custom Enterprise pricing are also available.

- **Focus mode with two clear tabs:** Focus mode separates people and anything needing a reply into Primary, while receipts, updates, newsletters, and promotions wait in Everything else.
- **Drafts written from the whole thread:** Replyless reads the full conversation and writes a ready-to-send reply in your tone, which you can make warmer, shorter, or firmer with one tap.
- **Auto-labeling on arrival:** Every incoming email is read and labeled on arrival - leads, invoices, and support requests route themselves, and it remembers your corrections.
- **Named inbox categories:** Create custom tabs like Clients, Finance, or Payments with sender, domain, or subject-keyword rules, and urgent mail surfaces at the top.
- **Background agents and automations:** Describe a routine job in plain language - a morning brief, sending invoices to Slack - and an agent runs it in the background with your connected tools.

**Strengths:** Works on top of Gmail, Outlook, and Zoho Mail without moving your mail; Focus mode and custom views make triage fast; Draft replies are generated from the full thread and match your tone; Background agents automate recurring work

**Limitations:** Priced per user, which adds up quickly for larger teams; Basics tier caps AI usage at 5,000 credits per month; Email-centric workflow is a big change for people deeply attached to their native client; Zoho support exists but Gmail and Outlook have the richest feature coverage
