## 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

## TestFit

TestFit is a real estate feasibility platform built for the earliest stage of a development deal — the point where you need to know quickly whether a site is worth pursuing. Instead of waiting weeks for a preconstruction team to produce a first draft, you map a parcel or draw a boundary, choose a typology, and let the software generate a complete, editable site plan with buildings, roads, turning radii, parking and topography. TestFit's own customers describe cutting initial site sizing from three to four weeks down to about ten minutes, and the platform reports usage across 6,200+ users.

The product is organised around three solvers. Site Solver handles automated feasibility and deal evaluation using generative design and detailed building presets. Parking Solver concentrates on surface and structured parking layouts, custom stalls and drive aisles. Urban Planner is the entry point for quick massing work, with 2D and 3D visualisation, road layouts, a yield estimator and unlimited users. Around those sit optional add-ons: Site Intelligence supplies parcel, environmental and zoning data plus 3D terrain and cut-and-fill analysis; Pro Forma live-links financials to the plan and imports your own Excel templates; and the MCP Connection lets you prompt site plans from an AI assistant.

Flipping the traditional workflow matters here — TestFit validates a pro forma against an actual physical layout rather than an assumed one, which is what makes the takeoffs for parking, infrastructure and earthwork worth trusting early. Approved layouts then flow into Revit, SketchUp, AutoCAD, Excel or PDF so the concept work survives into documentation, and live feasibility reports keep consultants and stakeholders aligned. Layouts cover multi-family, single-family, industrial, retail, hotel, data center and parking typologies.

**Pricing & Plans:** Paid, quote-based at the top end. Urban Planner is $75/month and Parking Solver $195/month, both billed monthly; Site Solver starts at $15,000/year and Site Solver Portfolio at $20,000/year, billed annually. Add-ons: Site Intelligence +$150/month, Pro Forma +$170/month, MCP Connection +$100/month.

- **Generative site planning:** Map any parcel or draw custom boundaries, then generate a buildable plan with road layout, turning radii and topography handled so you avoid redesign later.
- **Parking Solver:** Produce optimal surface and structured parking layouts, set custom stalls and drive aisles, and validate parking ratios without manual drafting.
- **Site Intelligence data:** Overlay parcel, environmental and zoning data, model 3D terrain with cut-and-fill analysis, and check power and utilities infrastructure before design assumptions harden.
- **Live-linked pro forma:** Connect financial models directly to your design, with live pro forma figures and import of your own Excel templates, to see whether a deal pencils.
- **Takeoffs and direct integrations:** Generate cost estimates for parking, infrastructure and earthwork early, and push approved layouts to Revit, SketchUp, AutoCAD, Excel or PDF.

**Strengths:** Turns site feasibility from a multi-week exercise into an hours-long loop, enabling far more alternatives per budget; Financials are validated against a real generated layout instead of a rough assumption; Approved plans push straight into Revit, SketchUp, AutoCAD, Excel and PDF, so early work is not throwaway; Comprehensive typology coverage, from multi-family and industrial to data centers and structured parking

**Limitations:** Entry price for automated feasibility starts at $15,000/year, which puts full generative design out of reach for very small teams; Site Intelligence data layers such as parcel, flood zone and zoning coverage vary by country; Training and support are English-only and operate during U.S. business hours; Generative design and detailed typology solutions are gated to the Site Solver tier upward
