## 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

## StreamDocs.ai (PDF.co)

StreamDocs.ai no longer operates as a standalone brand: the domain now forwards visitors to PDF.co, the PDF automation platform built by Artifex Software Inc., the company behind the PyMuPDF library. If you arrive at streamdocs.ai you land directly on PDF.co's marketing site, and the same product, credits and pricing apply.

PDF.co is a REST-based web API for document processing. Through a single API key you can extract structured data from PDFs and scans, convert PDFs to Excel, CSV, XML, JSON, HTML or images, merge and split files, fill forms, add watermarks and barcodes, and apply OCR to scanned pages. Because it is low-code, the same endpoints are exposed as no-code connectors for Zapier, Make and thousands of other apps, so business teams can automate document workflows without writing server code.

A notable recent addition is AI-powered invoice parsing: even without templates, the API turns PDF invoices into clean, standardised JSON. PDF.co also offers document classification and archive-ready PDF/A output. The service is trusted by 50,000+ users, is SOC 2 compliant, and is positioned for developers, finance teams and operations staff who need reliable, scriptable document automation.

**Pricing & Plans:** Freemium with a free trial (3,000 credits for one month, no credit card required), then monthly plans: Basic $8.99/mo (16,500 credits), Personal $22.49/mo (37,000 credits), Business 1 $44.99/mo (80,500 credits), Business 2 $89.99/mo (159,850 credits), Business 3 $270/mo (483,000 credits), and custom Enterprise pricing above 500,000 credits. Annual billing saves about 10%.

- **PDF extraction and parsing:** Pull structured data out of PDFs, scans and invoices via REST endpoints, or let AI invoice parsing return standardised JSON without any template.
- **Conversion and OCR:** Convert PDFs to Excel, CSV, XML, JSON, HTML and images, and run OCR on scanned documents to make them searchable and machine-readable.
- **Editing and management:** Merge, split, fill forms, add watermarks, barcodes and stamps, and generate new PDFs programmatically from HTML or templates.
- **3,000+ low-code integrations:** Official connectors for Zapier and Make expose the same API to no-code users, so document workflows can be automated without server-side code.
- **AI document classifier:** Automatically sort and organise incoming PDFs with custom classification rules, streamlining document management at scale.

**Strengths:** Mature, widely used API backed by Artifex and the PyMuPDF team; Broad endpoint coverage, from conversion and OCR to AI invoice parsing; Official no-code connectors for Zapier and Make; Generous free trial with 3,000 credits and no credit card

**Limitations:** Credits are consumed per page or call, so heavy volumes need larger plans; The streamdocs.ai brand is gone, so older bookmarks redirect unexpectedly; Toolkit is broad but each task still needs API plumbing or a no-code recipe
