# Ai Models And Market Trends

Summer 2023 YC batch: **247** companies, **55 %** B2B SaaS.

Winter 2024 YC batch: **260+** companies, ~**65 %** B2B/enterprise.

Summer 2025 YC batch: **160** companies, **108** B2B‑focused, **12** consumer.

I decided to adopt Meta’s Segment Anything Model 3 (SAM 3) for new video‑analytics products because its multi‑object understanding cuts labeling effort and speeds development.

sam3.inference_latency_ms = 30

sam3.throughput_objects_per_frame = >100

I recorded a timestamped placeholder for an AI/ML landscape overview on 2025-12-04.

Anthropic launched a new product called Claude Design.

Anthropic added Routines that run even when the laptop is closed.

OpenAI upgraded Codex with parallel agents that click and type on your Mac.

Roughly 65–70% of enterprise code is AI‑written now.

Claude Opus 4.8 introduces a native agentic runtime, moving away from the single‑turn chat paradigm.

- Up to 16 concurrent subagents per session

Effort control offers selectable reasoning depth levels (“Low”, “High”, “Extra High”, “Max”) to trade quality for compute cost.

GitHub Copilot integration uses a 15× premium request multiplier; usage‑based billing starts June 1 2026, prompting ~300‑word bulk prompts.

The release was announced 41 days after Claude 4.7 and is referenced alongside a ~$100 billion valuation.

- Up to 1,000 total subagents per session
- Dynamic workflows generated as JavaScript scripts executed locally

I mapped a GenAI stack as a vertical table on 2026‑08‑04, deliberately leaving out version numbers because half would be wrong by October. The table has ten conceptual layers and fifty concrete tools, but the layer labels themselves encode the typical AI project lifecycle.

- Ten layers in the stack.

I noticed that teams pick the top three layers early because they appear on high‑level diagrams and are easy to benchmark, while the bottom three layers (observability, guardrails, orchestration) are adopted later, each triggered by a concrete incident – a wrong output, a customer‑facing screenshot, or a demo that must survive a Tuesday.

The dominance of the LangChain ecosystem means that teams are not truly picking fifty independent tools; they inherit the opinions of a few ecosystems across multiple layers.

- Fifty tools mapped onto those layers.
- Three layers (Frontier Models, Inference, Evals) are usually selected in week 1.
- Layers 8‑10 are typically chosen at 11 pm by on‑call personnel.
- The LangChain family occupies three of the ten layers (LangGraph in frameworks, LangChain in retrieval, LangSmith in evals).
