 # Claude Agent SDK vs Sierra AI vs ASI Biont: Who Wins on Price? The AI agent market in 2026 has split into two camps: expensive enterprise solutions with convoluted subscriptions and affordable platforms where you pay for results. I analyzed the latest announcements from Anthropic and data on Sierra AI — here's what I found. ## Anthropic Claude Agent SDK: Beautiful but Expensive Starting June 15, 2026, Anthropic introduces separate monthly credits for the Agent SDK. Previously, you could run agents via the API and pay per token; now, there's a separate limit. Subscription prices: - Pro: $20/month — limited access to agents - Max: $100-200/month — a bit more, but still limits - Team: $30/person/month — for teams - Enterprise: custom pricing, typically $50-100+ per employee Plus API prices: Opus 4.6 — $15/1M input tokens. A full-fledged AI agent costs an enterprise client $500-2000/month per instance. ## Sierra AI: Only for Large Enterprises Sierra (a spin-off from Salesforce) is positioned as an enterprise platform for AI agents in contact centers. Pricing is not public — according to analyst estimates, starting from $5000/month for the basic package. Integration requires a team of developers and lawyers for compliance. ## ASI Biont: 8 Agents for 0 Rubles Subscription Our platform provides 8 ready-made AI agents (journalist, lawyer, trader, PR specialist, economist, travel agent, developer, insider) with no monthly fee. A new user receives 1500 tokens at the start — enough for a week of full team work. No hidden limits, no enterprise contracts. Comparison for small businesses (up to 50 employees): | Parameter | Claude SDK | Sierra AI | ASI Biont | |---------|-----------|-----------|-----------| | Subscription | $20-200/month | $5000+/month | 0₽ | | Agents | 1 (you build it yourself) | 2-3 (custom) | 8 ready-made | | Starting tokens | none | none | 1500 | | Integration | 2-4 weeks | 1-3 months | 15 minutes | | Russian language | partial | no | full | While competitors make you pay for every little thing — we simply provide working AI employees. Want to try it? Register, get 1500 tokens, and build your team of 8 AI agents. → [Get started with ASI Biont](https://asibiont.com/) This post is based on Anthropic Claude Pricing 2026, Claude Agent SDK changelog (May 2026), and open sources about Sierra AI.
