Anthropic
AIAI safety company behind Claude.
This mirrors the ChatGPT Plus playbook almost exactly at $20, putting Anthropic squarely in the mainstream premium-consumer bracket rather than undercutting on price. The Max tier is the differentiator — it's a bet that some users will pay well above the standard $20 ceiling for more headroom, going after the same power-user segment OpenAI splits between Plus and Team/Enterprise.
Plans: Free $0/mo per seat · Pro $20/mo per seat · Max $100/mo per seat
-
AssemblyAI
AISpeech-to-text and audio intelligence API.
They're positioning as the developer-friendly, API-first alternative to Deepgram and Rev AI — competitive on price at scale but differentiated by the breadth of AI features (LLM Gateway, multichannel, etc.). The AWS Marketplace listing signals they're actively chasing enterprise procurement budgets.
Plans: Pay as you go $0/mo · Custom Contact Sales
-
Avoma
AIAI meeting assistant and revenue intelligence.
At $19-39/seat, Avoma undercuts heavyweight conversation intelligence platforms like Gong or Chorus by a wide margin, positioning itself as the budget-friendly alternative for revenue teams that want AI meeting insights without enterprise-level spend. They're clearly hunting SMB and mid-market deals where buyers are price-sensitive but still want Gong-like functionality.
Plans: Startup $19/mo per seat · Organization $29/mo per seat · Conversation Intelligence $29/mo per seat · Enterprise $39/mo per seat
-
Baseten
AIML model deployment infrastructure.
Sitting in the middle-to-premium range for ML infra, Baseten isn't competing on being the cheapest raw GPU hours — that's a race to the bottom against hyperscalers. Instead they're chasing teams that want managed model-serving infrastructure without building it themselves, using the free entry point to hook developers before upselling the production-grade tiers.
Plans: Basic $0/mo · Pro Contact Sales · Enterprise Contact Sales
-
Braintrust
AIEvals and observability for LLM apps.
At $249/mo for Pro, Braintrust sits mid-to-premium in the LLM observability/eval space — not a rock-bottom self-serve tool, but not locked behind a full sales-only paywall either. They're clearly courting funded startups (hence the free-months discount) who need serious eval infrastructure but aren't ready for enterprise contracts yet.
Plans: Starter $0/mo · Pro $249/mo · Enterprise Contact Sales
-
Claude
AIAnthropic's AI assistant with Free, Pro, Max, Team, and Enterprise plans
Sitting right at the industry-standard $20/seat mark alongside ChatGPT Plus and other frontier AI assistants — not undercutting on price, competing on capability. The custom-priced Max tier signals they're chasing power users and businesses willing to pay well above baseline for more headroom, rather than racing to the bottom.
Plans: Free $0/mo per seat · Pro $20/mo per seat · Max Contact Sales
-
Cohere
AIEnterprise AI models and RAG.
Cohere is squarely targeting enterprise and developer teams that can't or won't send data to OpenAI or Anthropic — data residency, security, and deployment flexibility are the pitch. They're not the cheapest option, but they're positioning as the serious infrastructure play for regulated industries and large orgs that need control.
Plans: North Contact Sales · Compass Contact Sales · Model Vault Contact Sales
-
Comet
AIML experiment tracking and evals.
At $19/mo for Pro, Comet undercuts most enterprise-first MLOps and LLM observability tools that gate everything behind a sales call — this is a land-and-expand play aimed at developers and small teams who'd otherwise bounce off a 'contact us' wall.
Plans: Open Source $0/mo · Free Cloud $0/mo · Pro Cloud $19/mo · Enterprise Contact Sales
-
Copy.ai
AIAI-powered copywriting.
That $1000/mo Growth tier puts Copy.ai firmly in premium territory compared to Jasper or Writesonic, positioning it less as a writing tool and more as a GTM automation platform competing with category names like Clay. They're clearly not chasing solo creators past the Chat tier — they want mid-market revenue teams with real budget.
Plans: Chat $29/mo per seat · Growth $1000/mo per seat · Expansion $2000/mo per seat · Scale $3000/mo per seat · Enterprise Contact Sales
-
Deepgram
AIVoice AI for developers.
Deepgram plays the developer-friendly, usage-first lane against AssemblyAI and cloud giants like Google/AWS speech APIs — cheap to start, transparent-ish per-minute rates, but pricing opacity creeps in once you're comparing STT models, TTS, and Voice Agent add-ons that aren't in the tier table. They're chasing technical buyers who want to prototype fast and scale on consumption rather than negotiate a seat-based contract upfront.
Plans: Pay As You Go $0/mo · Growth Contact Sales · Enterprise Contact Sales
