@adocomplete I think it could be a good program. I got in while the discount never applied, and none of the support responded in the last two months...

English

@ClaudeDevs I have been granted this 6-month max -- while still getting charged for $200/month. None of the supports works :(
English

30 days. Four support channels. Zero human replies. And on May 20 Anthropic charged me a second $200 for a benefit that was supposed to be free.
I maintain PyOD, the open-source anomaly detection library (9.8k stars, 42M+ downloads). In March 2026 I was accepted into the Claude for Open Source Program, for "Max 20x free for 6 months."
Instead, on both invoices Anthropic's billing applied a "6 Months of Pro (100% off)" promo to my Max 20x subscription. The promo discounts $0, so I was billed the full $200 each month:
- April 20, invoice -0011: $200
- May 20, invoice -0012: $200
Same incorrect promo line both times. $400 charged, and the benefit I was accepted for has never applied.
For a month, no human has replied. The Fin bot did not route my explicit human-escalation request. support@anthropic.com and sales@anthropic.com have been silent since April 22. My GitHub issue was auto-labeled "invalid," then "stale."
I am not posting this out of frustration. I use Claude every day and want to keep doing so. Could @AnthropicAI or the Claude for Open Source team route ticket 215473995216928 to a human billing owner, reverse invoices -0011 and -0012, and apply the promised Max 20x OSS benefit? I can confirm the account details by DM.

In real healthcare operations, agents must do far more than answer medical questions. They need to read charts, interpret clinical and operational policies, verify coverage, route referrals, draft P2P scripts, and finalize care plans — where a single policy violation can mean a denied claim or missed patient outcome.
@actAVAai @iscreamnearby led and developed CHI-Bench (Clinical Healthcare In-situ Benchmark), the first long-horizon, policy-rich benchmark for AI agents operating across end-to-end U.S. healthcare workflows.
Key highlights:
▶️ High-fidelity simulators for Provider Prior Authorization, Payer Utilization Management, and Population Health Care Management, all exposed as MCP servers over patient, clinician, and insurer records.
🧪 Each trial runs 60–80 agent steps across 4–6 clinical stages, with access to 21 healthcare apps, 200+ MCP tools, and a 1,279-document operations handbook.
Leaderboard results across 30 frontier agents:
• Claude Code + Opus 4.6: 28% pass@1
• Codex + GPT-5.5: 21%
• Utilization review: 41%
• Care management: 32%
• Prior authorization: 29%
Reliability remains a major challenge: no agent exceeds 20% when the same case is repeated three times.

@AnthropicAI Accepted into the Claude for Open Source Program in March 2026 (promised "Max 20x free for 6 months"). My April 20 receipt shows the promo applied to "Pro" at $0, not Max 20x, so I was still billed $200.
Ticket 215473995216928 has been open since April 20. Email follow-up sent April 27. In-app Fin chat silent for a week despite an explicit human-escalation request.
Could the billing team look at the SKU mismatch? The receipt itself shows the promotion went to the wrong product.

🚀 agent-style: 21 drop-in writing rules that shape how AI coding agents write like a tech pro.
Works with any AGENTS.md-compliant tool: Claude Code, Codex, Copilot, Cursor, Aider, and more. 12 rules from canonical writing authorities (Strunk & White, Orwell, Pinker, Gopen & Swan), 9 from field observation of LLM output.
v0.3.0 sanity bench, AI-tell violations on 10 fixed prose tasks:
• Claude Opus 4.7: 105 → 58 (-45%)
• GPT-5.4 via Codex: 51 → 28 (-45%)
• Gemini 3 Flash: 79 → 14 (-82%)
How it works:
• Injected into the agent's system prompt, so the first draft already reads clean
• Deterministic audit layer catches em-dashes, transition openers, cliché verbs, contractions, same-starts
• One `pip install agent-style` or a drop-in AGENTS.md block

🚀 PyOD 3 is out, and the big change is agentic.
PyOD has long been the Python default for anomaly detection (scikit-learn style). v3 adds a new layer on top:
• Describe your problem in natural language
• An agentic investigator picks detectors, tunes parameters, runs the analysis, and explains the result
Under the hood, ADEngine orchestrates 60+ detectors, now covering time series, graphs, text, and images, not just tabular data.
Still a one-liner when you want control:
from pyod.models.X import X; X().fit(data)
38M+ downloads, ~10k GitHub stars. Used across fraud, security, medical, and ML robustness.
Install: pip install pyod
