## iPrep.Ai

iPrep.Ai is built for job seekers who want realistic interview reps without a human coach standing by. You start an AI-driven mock interview, answer questions the way you would in a real screen, and get detailed feedback once it wraps. The platform says 92% of its users successfully cracked interviews and presents industry-specific question banks that go beyond generic prompts.

Technical candidates get extra value from CodePad, which lets you write code live during a mock interview just as you would in a real technical round, with detailed feedback on your answers afterward. An analytics layer visualizes performance across question types and interviews, so you can see strengths at a glance and focus practice where it matters most.

Personalized feedback is central to the experience: each session breaks down communication, technical knowledge, and how you handle tricky questions, then suggests targeted exercises. Pricing is structured as interview packages with different volumes of roughly 45-minute mock interviews, each including expert feedback and practical coding questions, and the platform is used by candidates preparing for a range of company interviews.

**Pricing & Plans:** Paid packages priced in Indian rupees (₹). Starter offers 3 mock interviews, Pro offers 5, and Expert offers 10, each with roughly 45-minute sessions, expert feedback, and practical coding questions.

- **AI mock interviews:** Dive into mock interviews with AI-driven interviewers that feel realistic, with no complicated setup — just hit start.
- **CodePad for technical rounds:** Tackle real coding challenges during sessions just like a live technical interview, writing code directly on the platform.
- **Progress analytics:** Charts and graphs show where you excel across question types and interviews, turning performance into action points.
- **Personalized feedback:** After each session you get detailed feedback that identifies weak spots and offers exercises and targeted practice recommendations.
- **Saved practice history:** Sessions are saved automatically, so you can review past attempts and watch scores rise as you refine your approach.

**Strengths:** Realistic AI mock interviews available without scheduling a human coach; CodePad supports live coding practice for technical rounds; Analytics and personalized feedback give actionable improvement paths; Packages scale from a few interviews up to 10 sessions

**Limitations:** Packages are sold as interview credits rather than a simple monthly subscription; CodePad and analytics shine most for technical roles, less so for purely behavioral prep

## OpenAI Platform

While ChatGPT serves end users, openai.com and the OpenAI Developer Platform (developers.openai.com) provide the foundational API, SDKs, and enterprise infrastructure powering thousands of production AI applications worldwide. In late 2026, OpenAI's API catalog is anchored by the GPT-6 and GPT-6.1 model suite—all featuring a 1.05-million-token context window and up to 128K output tokens. The lineup spans GPT-6 Astra for frontier reasoning and mission-critical research, GPT-6.1 Sol for near-Astra intelligence at one-fifth the price, GPT-6.1 Terra for fast visual reasoning and computer use, and GPT-6 Luna for ultra-high-volume, low-latency tasks, alongside specialized models like `gpt-5.3-codex` and `gpt-6-astra-law`.

The OpenAI Platform has evolved well beyond basic chat completion endpoints. Through the unified `v1/responses` API, developers can orchestrate stateful multi-step agents equipped with built-in server-side tools—including live web search, vector file search, code interpreter sandboxes, and GUI computer use—without stitching together external orchestration frameworks. Every flagship model supports configurable reasoning effort (`none`, `low`, `medium`, `high`, `xhigh`, and `max`), strict JSON schema Structured Outputs, and multimodal image/audio inputs, while `gpt-live-1` powers per-second billed speech-to-speech voice agents.

OpenAI bills API usage on a transparent consumption model scaled across usage tiers (Build, Launch, and Grow, scaling up to 40M+ tokens per minute). In 2026, aggressive price cuts on the 6.x generation dropped entry-level intelligence on GPT-6 Luna to $0.10 per million input tokens and $0.50 per million output tokens, while GPT-6.1 Sol runs at $2/$10 and flagship GPT-6 Astra sits at $10/$50. Engineering teams can cut spend by 90% on repeated context using automatic Prompt Caching, save 50% on asynchronous workloads via the Batch API, and enforce regional data residency with a 10% compliance uplift.

**Pricing & Plans:** Usage-based pay-per-token API billing: GPT-6 Astra at $10/1M input and $50/1M output tokens; GPT-6.1 Sol at $2/1M input and $10/1M output; GPT-6.1 Terra at $1/1M input and $5/1M output; GPT-6 Luna at $0.10/1M input and $0.50/1M output; GPT-Live-1 voice at $0.05/minute; 90% discount on cached inputs and 50% off via Batch API.

- **GPT-6 & GPT-6.1 Model Lineup with 1.05M Context:** Spanning GPT-6 Astra ($10/$50 per MTok), GPT-6.1 Sol ($2/$10), GPT-6.1 Terra ($1/$5), and GPT-6 Luna ($0.10/$0.50), all with a 1,050,000-token context window and 128K max output.
- **Configurable Reasoning Effort Controls:** Tune thinking token budgets per API request across six granularity levels (`none`, `low`, `medium`, `high`, `xhigh`, `max`) to balance latency, accuracy, and cost.
- **Responses API & Native Computer Use Tools:** Combine model inference with hosted web search, file search, function calling, and autonomous GUI computer-use actions in a single stateful API call.
- **GPT-Live-1 Realtime Voice API:** Build ultra-low-latency multimodal voice agents billed per second ($0.05/minute) without rounding up to whole minutes.
- **90% Prompt Caching Discount & Batch API:** Cached input tokens bill at just 10% of standard input rates, while asynchronous 24-hour Batch API jobs cut both input and output token costs by 50%.

**Strengths:** 100-fold cost flexibility from GPT-6 Luna ($0.10/$0.50 per 1M tokens) up to frontier GPT-6 Astra ($10/$50 per 1M tokens); Unified 1.05M-token context window and 128K output limit across the entire flagship GPT-6 and GPT-6.1 family; 90% discount on cached input tokens and 50% Batch API discount dramatically reduce production inference bills; Industry-standard SDKs, Structured Outputs, and built-in Responses API tools minimize boilerplate agent code

**Limitations:** Long-context requests exceeding the standard window threshold trigger roughly 2x higher per-token billing rates; Flagship GPT-6 Astra ($10 input / $50 output per 1M tokens) is significantly more expensive than Claude Opus 5.5 ($4/$20) and Grok 4.7 ($2/$6); Regional data residency endpoints incur a 10% price uplift on models released after March 2026
