## 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

## ProofUp

ProofUp is a tenant screening platform built for multifamily property operators who need to confirm that an applicant can actually pay the rent. Instead of trusting whatever pay stub gets uploaded, it verifies income directly: applicants connect their bank and payroll accounts through Plaid, and earnings are read from the account rather than from a document. For those who upload instead, AI reads deposit frequency and actual earnings, which extends coverage to gig workers and guarantors.

The second layer is identity. A government-issued ID is photographed front and back, a live selfie is captured, and facial recognition confirms the two match — addressing the gap between the name on paper and the person who shows up. The third layer examines uploaded documents at the data level, checking file structure, metadata, and generator fingerprints for tampering that looks clean to the eye.

Everything converges into a single verdict per application — one of five, each carrying a risk level and the evidence behind it. Notably, the platform grades evidence quality: a direct bank connection differs from a source-downloaded PDF, which differs from a scan or phone photo. That distinction lets an approval team move fast while a review team still knows which applications deserve a sample. ProofUp positions itself against unverified approvals, which it says default far more often.

**Pricing & Plans:** Contact for pricing. ProofUp does not publish public tiers on its site; pricing is arranged through a demo request and depends on portfolio size and screening requirements.

- **Income verification from the source:** Applicants connect bank and payroll accounts through Plaid so earnings are read from the account itself, with no document in the path to forge. Uploaded documents are also analyzed for deposit frequency and real income.
- **ID plus live selfie matching:** A government ID photographed front and back is matched against a live selfie using facial recognition, catching borrowed identities before keys are handed over.
- **Document forgery detection:** Uploaded PDFs are read at the byte level for hidden text layers, metadata mismatches, generator fingerprints, and post-generation edits — evidence that visual inspection misses.
- **Five graded verdicts with reasons:** Each application returns one of five verdicts (pass, pass with caution, non-recurring, needs review, fail) with a risk level and the specific signals that produced it.
- **Auditable decision trail:** Reports record verification method, document source, per-attempt history, and plain-language flag explanations, so decisions are defensible and reviewable.

**Strengths:** Income is verified from the account via Plaid, so there is no forgeable document in the strongest path; Combines income, identity, and document-fraud checks in a single 2-3 minute flow; Five graded verdicts with explicit reasons and risk levels beat a simple pass/fail; Evidence-quality grading separates source-downloaded PDFs from scans and photos

**Limitations:** No public pricing — you must book a demo to get numbers; Strongest results depend on applicants connecting bank and payroll accounts, which some may resist; Document-level fraud analysis only applies to applicants who upload files rather than connect accounts
